A single-use product having a laminate web having a slit area of the art
The invention relates to a disposable article having a multi-layered laminate web with slotted openings and a utility component.
BACKGROUND OF THE INVENTION
Disposable articles having laminate webs formed by bonding the individual webs by laminating are well known for various applications. For example, laminate, nonwoven webs are often used in disposable absorbent articles, such as diapers, adult incontinence products, cleaning products, polishing articles, etc. Nonwoven fabrics and nonwoven laminates are also used to impart additional bulk or softness to the web component. Similarly, foil or foil laminate strips can provide advantages by combining the parameters of the various foils that they stack together. Laminate strips can also be called composite strips.
Less common examples of laminate strips include laminates of mutually different materials. The materials may be different from each other in terms of mechanical tensile properties, thermal properties, or visual or tactile properties. For example, the nonwoven web may be attached to a relatively solid fabric to provide a soft feel to the fabric surface. Different materials can be joined by fusion bonding, gluing, ultrasonic bonding and the like. Bonding methods are often determined by the materials themselves, but often require bonding by gluing. For example, a laminate or composite of materials having widely differing melt properties may require an adhesive layer between the laminate layers. Even materials having similar melt properties to nonwoven and thermoplastic film materials are often bonded by the adhesive for proper bonding to prevent unwanted breakdown. Such manufacturing processes can be expensive due to the addition of adhesive, and the resulting laminate is often relatively stiff, depending on the amount in which the adhesive is added.
Slotted apertured laminate strips can be made by methods known in the art. One preferred method of forming slotted holes in a nonwoven web is described in U.S. Patent 5,916,661. Described herein is a laminate material having, for example, at least one layer by drawing spun fibers bonded to a nonwoven web bonded to at least one layer of a spunbonded gas stream bonded to a nonwoven web, carded nonwoven web or other suitable material. Such slit-shaped strips may be used as the topsheet for a disposable absorbent article. However, this document does not disclose slit laminate strips of completely different materials, e.g. materials of different material classes or having different material properties.
As noted, nonwoven webs are preferred as components of disposable absorbent articles such as diapers, incontinence briefs, gym shorts, feminine hygiene garments and the like, as well as personal cleansing products such as disposable wet handkerchiefs. or substantially dry tissues. Non-woven materials are also preferred components in other products such as disposable garments, surgical products such as drapes, surgical gowns, etc., durable garments, automotive components, car and upholstery furniture products, filter media, care products. household polishes, eg polishing cloths, dusters etc. and other consumer or commercial goods. The nonwoven materials used in these and other applications benefit from their diverse visual and tactile properties. However, when used alone, monolayer nonwoven materials are limited in the range of advantageous properties, including visual, contact, strength, or absorbent properties, by limiting known manufacturing methods, particularly as compared to woven or knitted materials.
Therefore, it would be desirable to have a disposable article comprising a laminate web composed of webs with different material properties.
It would also be desirable to have a disposable article having a laminate web formed by joining layers without adhesive.
Further, it would be desirable to have a disposable article having a slit-like laminate strip having visually distinct areas giving a fabric or knitted look and feel.
SUMMARY OF THE INVENTION
These deficiencies are largely eliminated by a disposable product having a
(a) a laminated strip with slotted apertures, containing:
1) a first extensible strip having a first elongation at break;
2) a second extensible strip attached to the first extensible strip at the joining points, having a second extension at
-interruption, and
3) a third sheet material that is disposed between the first and second sheets, the third sheet material having a third elongation at break that is greater than both the first and second elongation at break;
b) a utility component disposed adjacent to the laminate strip.
In another embodiment, a slit-apertured laminate web having a first expanding web and a second expanding web are joined together at spaced apart bonding locations and a third material positioned between the first nonwoven web and the second nonwoven web. The first nonwoven web, the second nonwoven web, and the third nonwoven web are fluid interconnected through slotted apertures and have distinct areas that are distinguished from one another by at least one of the properties selected from the group consisting of basis weight, fiber orientation, thickness, and density.

Detailed description of the invention:
As used herein the term absorbent article means articles that absorb and contain liquids (ie, water, detergents, conditioners, polishes, body exudates). In some cases, does this mean products that are placed? against or near the body apertures of the wearer to absorb and contain various exudates excreted by the body. In other cases, the term means articles which have the ability to absorb and retain the substance until the product is used by the consumer for its intended purpose.
The term "disposable" is used herein to describe articles of the present invention that are not intended to be laundered or otherwise restored or used for a long period of time, i.e. it is primarily intended to be discarded after 25 uses, more preferably after 10 uses, more preferably after 5 uses, and most preferably after a single use. Preferably, such disposable products are recycled, composted or otherwise disposed of in an environmentally acceptable manner. One unit forming a disposable product refers to disposable products that are formed from separate parts joined together so as to form a coordinated unit so as not to require special handling parts such as a separate holder and insert.
The term nonwoven web as used herein refers to a web having the structure of individual fibers or yarns interleaved with one another, but not in some regular, repetitive manner. Nonwoven webs have in the past been produced in a number of ways, such as meltblown spinning methods into a gas stream, methods for drawing fiber from a nozzle and bonding to a nonwoven web, and methods of forming a bonded carded web.
As used herein, the term microfiber means small diameter fibers having a mean diameter of no greater than about 100 µm (microns).
As used herein, the term meltblown fibers means fibers formed by extruding molten thermoplastic material through a group of fine usually circular capillaries in the spinneret as molten fibers or into a gas stream moving at high velocity, e.g. thinens the fibers of the molten thermoplastic material to reduce their diameter until they have a microfiber diameter. Thereafter, the fibers so produced are entrained by a gas stream moving at high speed and deposited on the collecting surface where they form a web of randomly dispersed fibers.
As used herein, the term spunbonded fibers means small diameter fibers that are formed by extruding a melt of thermoplastic material as fibers from a group of fine, usually circular, capillary spinnerets, with the diameter of the extruded fibers being rapidly reduced thereafter. dragging.
As used herein, the term polymer generally includes, but is not limited to, homopolymers, copolymers such as block, graft, random and alternative copolymers, terpolymers, etc., and mixtures and modifications thereof. Further, unless otherwise specifically limited, the term polymer will include all possible geometrical configurations of the material. Such arrangements include, but are not limited to, isotactic, syndiotactic, and statistical symmetry.

As used herein, the term "elastic" refers to a material that can be pulled out, i.e. elongated by at least 60%, i.e., to a stretched stretch length that is at least 160% of the relaxed unstretched length, and that returns from at least 55% of its elongation after release of the tension elongation force. A hypothetical example would be a sample of 25.4 mm (1) long material that can be extended to at least 40.64 mm (1.60) and which returns to 40.64 mm (1.60) after release and returns to a length of not more than 32,26 mm (1,27). Many elastic materials can be extended by more than 60%, ie. much more than 160% of their unstretched length, for example, to extend by 100% or more, and many of these materials return substantially to their initial unstretched length, for example, to 105% of the initial unstretched length after release of the pulling force.
As used herein, the term inelastic means a material that does not fall within the definition of the above elastic material.
As used herein, the term extensible refers to a material that can be extended by at least 50% after application of the extensible force without devastating failure.
The products according to the invention comprise the following basic parts: laminate strip, utility component and optional other components.
Laminate belt:
The laminate web 10 of the article of the present invention has at least three layers, strips or diapers disposed in a layer relative to the forehead as shown in Figure 1. The layers should be thin enough to be processed as is. as described herein, but are not limited to any thickness (i.e., total thickness)

The first outer layer 20 and the second outer layer 40 are known as a first extensible strip having a first elongation at break and a second extensible strip having a second elongation at break. Preferably, the second outer layer comprises the same material as the first outer layer, but may be of a different material. At least one third, central layer 30 is disposed between the two outer layers. The laminate web 10 is heat calendered as described below to provide a plurality of fusion bonding sites 50 that serve to join the layers 20, 30 and 40 to form a single web forming the web. Although the laminate web 10 is primarily described in connection with nonwoven webs and composites, in principle, the laminate web 10 may be made of any web material that meets the requirements, ie, melt properties, extensibility, as described herein. The layers may be films, microporous films, apertured films, and the like.
Preferably, the first and second outer layers are nonwoven.

Methods for making nonwoven materials are well known in the art. Generally, these nonwoven materials can be made by air laying, water laying, melt pulping in an air stream, coforming, spinning nonwoven fibers, or carding, wherein the fibers or filaments are first cut to desired lengths from long strands that enter the water or air stream. and then deposited on a screen through which air or water-laying fibers pass. The resulting layer, irrespective of its method of manufacture or composition, is then subjected to at least one or more types of bonding operations to anchor the individual fibers to form a self-supporting web. In accordance with the present invention, layers comprising nonwoven materials can be prepared by a variety of processing methods including, but not limited to, air entanglement, hydroentangling, thermal bonding, and combinations thereof.
The more extensible third core layer may also be nonwoven as described above, but the core layer 30 itself does not need to be thermally compatible with the outer layers. The core layer 30 need not be melt processable either. It can be, for example, a cellulosic material such as paper, soft paper, paper towels, paper napkins, woven or knitted material such as cotton or rayon blends or a thermosetting material such as a polyester or aromatic polyamide foil. The core layer 30 may be another nonwoven material having suitable properties for processing into an apertured layer. When the core layer 30 has a melting point, this temperature is preferably at least about 20 ° C higher than the temperature of the outer layers. However, the core layer 30 may not have a melting point and may simply become softened at the calendering temperatures required to bond the laminate.

One of the unexpected advantages of the present invention is the discovery that the novel properties of the belt can be given by the choice of a central layer 30 located between the two outer layers. The core layer material is preferably selected from the group consisting of thermoplastic webs, polymeric films, elastic sponges, molded films, and combinations thereof. However, it is important that the middle layer has a third elongation at break that is greater than that of the first outer layer 20 and the second outer layer 40. The wide range of possible core layer materials 30 allows a surprising variety of structures according to the present invention, each having a preferred use in a wide variety of end uses.
Suitable materials for the core layer 30 are elastomeric polymeric films such as microscopically expanded, vacuum-shaped, three-dimensionally shaped films described in US 08/816 106. The core layer may further be a three-dimensionally shaped film having micro-holes as described in the patents US 4,629,643 and US 4,609,518.
The central layer 30 may be a web material having a stretchable web as described in U.S. Pat. No. 5,518,801. Such a web may be a Structural Elastic-Like Film (abbreviated to SELF) formed, for example, by embossing matt plates, or cylinders.
The central layer 30 may be a web of absorbent foam with an open cell. Particularly suitable absorbent foams for high performance absorbent articles, such as diapers, are those made from High Internal Phase Emulsions (abbreviated to HIPE), see, for example, U.S. Patent Nos. 5,260,345 and 5,268,224. HIPE foams provide desirable handling properties * 44

(a) relatively good wick suction and fluid distribution parameters for transporting aspirated urine or other bodily fluid away from the initial contact zone and other areas of the foam structure to allow subsequent fluid outflows to be received; and
b) a relatively high storage capacity with a relatively high fluid capacity under load, i.e. under compressive forces.
Further, since the laminate web 10 is formed without the use of thermoplastic adhesives, durable properties can be obtained as with a garment. Such laminates can be washed several times before unacceptable wear occurs.
As shown in FIG. 2, the center layer 30 is selected such that when the layers of the laminate web 10 are processed as shown below, portions of the center layer 10 in the region of the fusion joints 50 are separated. thus allowing the first outer layer 20 by melting to bond directly to the second outer layer 40 at the interface 52 of both materials at the fusion bonding points, 50. Without wishing to be bound by theory, it is believed that the method of the present invention facilitates such separation of the core layer 30 by melting, shearing, cutting or otherwise breaking the core layer 30 and sufficiently deflecting the material off the core layer 30 to allow thermal joining two outer layers.
Without wishing to be bound by theory, it is believed that in order to bond the layers of the laminate strip so as to subsequently form holes therein, the thermal bonding should be formed by calendering with the thermal tips described below. ··

4444 sites having a narrow W width and a high aspect ratio. For example, Fig. 3 shows the melting region of one melting joint 50 having a narrow width width W and a large aspect ratio, i.e. the length L is substantially greater than the width W. The length L should be selected so as to allow for a proper joint area, while the width W is narrow enough to allow the projection that is used to form the joint (as described below) to cut, punch or otherwise pierce a central layer 30 in the region of the joints as described below. The width W may be in the range of 0.0762 to 0.508 mm (0.003 to 0.020), but in a particularly preferred embodiment it is in the range of 0.127 to 0.254 mm (0.005 to 0.010) and may be adjusted depending on the properties of the core layer 30. In the embodiment, only the layer (s) 30 is punched such that the central layer is punched after joining, while the outer layers are in a bonded unpunched state. However, for some end use requirements, it may be desirable that the protrusions used to form the joining sites cut, punch, pierce or otherwise shape the apertures through the layers 20, 30, 40 at some or all of the joining sites.
It is believed that the aspect ratio can be as low as 3 (ie, the L / W ratio is equal to 3/1). It may also be between 4 and 20. In one preferred embodiment, the aspect ratio was about 10. The aspect ratio of the fusion bonding points 50 is limited only by the corresponding aspect ratio of the points connecting the projections of the calender roll or rolls as described in detail below.
In a preferred embodiment, the longitudinal axis of each connection point I, which corresponds to the directional length dimension of the connection point 50, is located in a regular, repeating pattern oriented generally in the machine direction, MD, as shown in Figure 1.

However, the connection points may be located in a regular repeating pattern oriented in a cross machine direction or randomly oriented in a cross machine direction and along the machine. For example, the joints 50 may be located in a herringbone pattern.
A further advantage of the present invention is obtained when the heat bonded laminate web described above is stretched or elongated in a direction generally perpendicular to the longitudinal axis 1 of the fusion bonding points 50. The fusion bonding at the fusion bonding points 50 tends to create local weakened areas of the band at bonding points. As the sites of the strip 10 extend in a direction generally perpendicular to the longitudinal axis I of the joining sites 50, the material in the joining site will not withstand stress and a slotted opening will be formed. The relatively large aspect ratio of the melting joints 50 makes it possible to create a relatively large slit-shaped opening after sufficient stretching. When the laminate web 10 is evenly stretched, the result is a regular pattern of a plurality of slotted apertures 60 that corresponds to the pattern of the fusion bonding locations 50.
Giant. 4 shows a fragmentary sectional view of a slit-shaped laminate strip according to the present invention. As can be seen, the partial cross-sectional representation makes it possible to show each layer or diaper in plan view. The laminate strip 10 shown in FIG. 4 is produced after the thermally bonded laminate has been pulled out in a direction perpendicular to the longitudinal axis of the melting joints 50, in this case across the machine CD. As shown, where the fusion bonding points 50 were previously, slit-shaped openings 60 are formed because relatively weak bonding points 50 do not withstand stress. It is also shown that the central layer 30 can remain substantially evenly distributed in the laminate 10 depending on the material properties of the central layer.

4 If the center layer 30 is more extensible than the first outer layer 20 or the second outer layer 40, then it simply expands, possibly by plastic deformation, but remains generally uniformly distributed in the non-perforated areas of the belt 10. For example, when utilizing the thermoplastic film as the central layer 30, extends either extensibly or elastically (depending on the type of film), but may remain generally uniform, for example in terms of density or basis weight.
When the slits 60 are formed, the thermally bonded portions of the layers 20, and 40 remain primarily on portions of the circumferences of the slotted openings corresponding to the length dimension of the joining points 50. Therefore, each of the slotted openings 60 does not have a circumference of thermally bonded material. 4. One advantageous feature of such a laminate strip is that once the slit holes have been made therein, fluid communication in the middle layer is facilitated. Thus, the absorbent layer 30 may be used between relatively non-absorbent outer layers and the laminate could be an absorbent cloth with a relatively dry-to-dry outer surface.
Giant. 5 is a schematic cross-sectional view of what is shown in FIG. 4. As can be seen, slit-like openings 60 are formed when the laminate web is pulled out in the T direction.
In some particularly preferred embodiments, the laminate web has from 10% to 20% of the surface area as an open area. As used herein, the term "open area" means that the web has slotted openings or includes openings such that the amount of material needed to cover a certain region is minimized due to the expansion of the web that occurs after pulling out, by curling into a circle. More preferably, the open area of the web is from 11% to 17%.

A surprising advantage of the laminate web structure shown in FIG. 6 is the presence of separate areas in the non-perforated portion of the web, distinguished by at least one property selected from the group consisting of basis weight, thickness, density, and combinations thereof. As can be seen from the section in FIG. 7, several such areas can be distinguished. In a particularly preferred embodiment, they are regions<sup>-</sup>Visually different and give the laminate strip an aesthetically pleasing appearance and feel which is particularly useful in the products of the present invention. The regions may also give the laminate a texture as if it were a garment or knit.
As can be seen from FIG. 7, several structurally different regions can be distinguished in the section shown. The region indicated by 64 corresponds to the slit 60. In the non-apertured belt region, the region 66 is a relatively high basis weight region comprising a central layer 30. The region 68 represents the portion of the laminate strip in which the central layer 30 has ruptured and separated. present, creating an area with a relatively low basis weight of the web 10. In general, regions of higher basis weight will also be regions of correspondingly higher density, but need not be. For example, a post-stretch embossing method may be applied to the web 10 to form multi-density regions in addition to multi-basis weight regions. For high basis weight or high density areas, differences can often be discernible by simply swiping between fingers.
Generally, a laminate web 10 having generally parallel rows of melt bonding points 50 extending in the machine direction MD that accordingly form generally parallel rows of slit-shaped apertures 60 when they are pulled out and having a central layer 30 with lower elongation at break than outer layers 20, 40 , the resulting drawn, apertured laminate web 10 has a generally low basis weight, low density regions between the slot-like openings 60 in the machine direction MD, e.g., the region 68 of Figures 6 and 7. Similarly, the laminate web 10 has a relatively high basis weight, regions of high density between adjacent rows of apertures 60 in the cross-machine direction of the CD, e.g., region 66 in Figure 7. the embossing can be varied similarly to the thickness of the laminate strip, the thicker regions generally corresponding to the higher density regions.
Another embodiment of the laminate web 10 usable in the present invention that uses nonwoven webs as the outer layer has distinct areas differentiated by fiber orientation. Different fiber orientation can be achieved by providing localized areas in the web 10 that are subjected to greater pulling than other areas. For example, by tensioning the web 10 more extensively in the regions corresponding to the regions 68 in FIG. 6, regions with significant fiber reorientation are formed. Such local tension can be produced by the method of the present invention as detailed below.
Giant. 8 is a photomicrograph showing in enlarged detail the web of the present invention which has been stretched to form holes and locally stretched to form fiber reorientation areas 68. As can be seen in FIG. 8, by locally pulling out portions of the belt more than elsewhere, the slits thus formed may have different sizes. The area generally referred to as 70 in FIG. 8 has undergone greater tension, i.e., local pull, than the area designated 72. Thus, the slit-shaped openings in the region 70 are larger than the slit-shaped openings in the region 72 and the basis weight of the nonwoven web material in the region 72 is less than the basis weight of the nonwoven web in the region 70. In addition to the difference in basis weight due to localized stress differences For example, the laminate web of the present invention may also have different fiber reorientation areas 68. In these areas, the fibers were reoriented from a general random orientation to a predominant orientation in the elongation direction.
In addition, more than one core layer 30 may be advantageously used. For example, a laminate strip having a core layer of polymeric film and a further core layer having a cellulosic soft material, both core layers positioned between the first nonwoven outer layer and the second nonwoven outer layer may an absorbent wiping product in which one side is relatively more absorbent than the other. When the central layer of the polymeric film is present, it may be a three-dimensional shaped film such that the side of the film can impart additional texture to the laminate, which is advantageous in many wiping applications. Macroscopically expanded, three-dimensionally shaped films suitable for use in the present invention include those described in U.S. Patents 3,929,135 and 4,342,314.
The core layer 30 may further comprise absorbent gelling materials. For example, superabsorbers or hydrogel materials can provide excellent absorbency when the laminate web of the present invention is used as an absorbent cloth or core in the disposable absorbent article of the present invention. As used herein, a hydrogel is an inorganic or organic compound capable of absorbing aqueous fluids and retaining them at moderate pressures. For good results, hydrogels should be insoluble in water. Examples are inorganic materials such as silica gels and organic compounds such as crosslinked
<img file="CZ20021933A3_D0002.tif" />
polymers. The crosslinking can be induced by covalent, ionic, van de Waals or hydrogen bonds. Examples of such polymers are polyacrylamides, polyvinyl alcohol, copolymers of ethylene and maleic anhydride, polyvinyl ethers, hydroxypropylcellulose, carboxymethylcellulose, polyvinylpyridine and the like. Suitable gelling materials are described below as optional ingredients relating to the personal care products of the present invention. However, it will be understood that such gelling materials may also be utilized in each of the articles of the present invention, regardless of the intended use of the article.
The structure of the laminate web is particularly useful in the product package of the present invention since the web can be made of 2. different materials without the use of adhesive or bonding. The plurality of fusion bonding points 50 are sufficient to hold the webs together in the laminate web so that the laminate web behaves as a single web and retains integrity in processing and use without undesirable delamination. However, in some embodiments and in some materials, it may be advantageous to apply adhesive between at least two of the layers of which it is composed.
Method of production of laminate strip:
FIG. 9 schematically illustrates a method 100 for manufacturing a laminate web for the subject articles.
The first, relatively extensible web 120 unwinds from the first supply roll 104 and moves in the direction indicated by the arrows associated therewith. Similarly, the second, relatively extensible web 140 is unwound from the second storage roll 105. The center layer 130 is similarly unwound from the third storage roll 107. The three components or more, when more than one center layer is used, pass through the gap 106 of the device 108. a connecting roller with heat points, formed by rollers 110 and 112.
Any outer layer may comprise a shaped film, such as a three-dimensionally shaped film having micro-holes as described in U.S. Patents 4,629,643 and 4,609,518.
In a particularly preferred embodiment, the two outer layers comprise nonwoven<sup>-</sup>and can be the same. The nonwoven material can be formed by known nonwoven extrusion methods, such as known methods for extruding a melt into a gas stream or known methods for withdrawing a fiberized fiber and passing directly through the gap 106 without first being bonded or deposited as storage rolls. In a preferred embodiment, however, the nonwoven webs are heat-merely bonded (consolidated) webs which are commercially obtainable as a roll of material.
The nonwoven webs of the outer layer (s) may be elastic or inelastic to the extent that the third central layer is more extensible than both the first and second outer layers. The nonwoven web may be any meltbonded web, including a nonwoven web of filament withdrawal, a nonwoven web of gas-spun fibers, or a bonded carded web. When the nonwoven web is a spunbonded fiber web, it may include meltblown microfibers. The nonwoven web may be made of fiber-forming polymers such as polyolefins. Examples of polyolefins include one or more of the following polymers: polypropylene, polyethylene, ethylene copolymers, propylene copolymers, and butene copolymers. The nonwoven web may have a basis weight in the range of 10 to 60 g / m 2<sup>2</sup> and more preferably 15 to 30 g / m 2<sup>2</sup>.
The nonwoven outer layers may be any multilayer material having, for example, at least one layer of a spunbonded web
9 Bonded to at least one layer of a meltblown web, a bonded carded web, or. other suitable material. For example, the nonwoven web may be a multilayer web having a first layer of spunbonded polypropylene having a basis weight of 6.8 g to 271.2 g / m 2<sup>2</sup> (0.2 to 8 ounces per square yard), and a second meltblown polypropylene layer having a basis weight of 6.8 g to 135.6 g / m 2<sup>2</sup> (0.2 to 4 ounces per square yard) and a second spunbonded polypropylene layer having a basis weight of 6.8 g to 271.2 g / m 2<sup>2</sup> (0.2 to 8 ounces per square yard). Alternatively, the nonwoven web may be a single layer of material, such as a spunbonded web having a basis weight of 6.8 g to 339, 1 g (from 0.2 to 10 ounces per square yard) or a meltblown web having a weight of 6.8 g to 271.2 g / m<sup>2</sup> (0.2 to 8 ounces per square yard).
The outer layers of the nonwoven web may also be a composite formed from a mixture of two or more different fibers or a mixture of fibers and particles. Such blends can be formed by adding fibers or particles to a gas stream in which fibers produced by spinning are entrained into the gas stream or spinning to form a thoroughly intertwined mixture of fibers and other materials such as wood pulp, staple fibers and particles prior to collection. fibers.
Prior to processing the laminate web as described herein, the outer fiber coverings of the respective layers may be bonded to form a coherent web structure. Suitable bonding methods include, but are not limited to, chemical bonding, ultrasonic bonding, thermal bonding such as point calendering, hydroentangling and needling.

Referring to Figures 9 and 10, a roll bonding arrangement 108 for nonwoven materials is shown, which preferably comprises a patterned calender roll 110 and a smooth counter roll 112. One or both of the patterned calender rolls 110 and the smooth counter roll 112 may be heated, and the pressure between the two rolls may optionally be adjusted by well known means to provide the desired temperature and pressure ± ak to simultaneously deflect the center layer 30 at the fusion joints. two outer layers at the bonding points were fused together.
The patterned calender roll 110 is configured to have a circular cylindrical surface 114 and a plurality of protrusions or protruding protrusions 116 that extend outwardly. The projections 116 are spaced in a predetermined pattern, each projection 116 being arranged and positioned to deflect the central layer 30 at the fusion joints and fuse the two outer layers together in a plurality of locations. One pattern of the projections 116 is shown in FIG. 11. as can be seen, the protrusions 116 have a relatively small width WP, which may be between 0.0762 mm and 0.508 mm (0.003 and 0.020), but in a preferred embodiment it is about 0.254 mm (0- 010). The protrusions may have a length of LP in the range of 0.762 mm to 5.08 mm (0.030 to 0.200 "), preferably about 2.54 mm (0-, 100). In a preferred embodiment, the projections have an aspect ratio of 10. The pattern shown is a regular, repeating pattern of checkerboard spaced projections, generally in rows, each separated by a row spacing RS that is in the range of 0.254 mm to 5.08 mm (0.010 to 0.200). In a preferred embodiment, the row spacing RS is around 1.524 mm (0.060). The projections may be spaced apart in a row with a pitch, in a series PS, which is generally equal to, the length of the projection LP. However, the pitch and pattern may vary in any way depending on the desired end product.

As shown in FIG. 10, a patterned calender roll
110 may have a recurring pattern of protrusions 116 that extend around the entire periphery of the surface 114. Alternatively, the protrusions 116 may extend around a portion or portions of the periphery of the surface 114. Similarly, the protrusions 116 may be in a non-repeating pattern or a repeating pattern of randomly oriented protrusions.
The protrusions 116 are preferably truncated conical shapes that project radially outwardly from the surface 114 and which have rectangular or somewhat elliptical surfaces 117 at the distal end. While it is not intended to limit the scope of the present invention to the protrusions of this configuration only, it is currently believed that a high aspect ratio of the melting joint 50 can only be achieved if the protrusions also have a narrow width and large aspect ratio at the distal end surface 117. As shown above with reference to Fig. 11. Without wishing to be bound by theory, it is understood that other suitable shapes of the distal ends 117 may in particular be circular, square, rectangular, etc., to facilitate bonding and punching of the laminate web. The roller 110 preferably has a finish such that all end surfaces 117 lie in an imaginary truly circular cylinder that is coaxial with respect to the axis of rotation of the roller 110.
The height of the projections should be selected according to the thickness of the laminate to be joined. In general, the height dimension should be greater than the maximum thickness of the laminate strip during the calendering process, so that a proper bonding occurs at the bonding points and only at the bonding points.
The counter roller 112 is preferably a completely circular, smooth-surface steel cylinder. After passing through the gap 106, three strips or more of strips 120, 130, and 140 are formed into a laminate strip 10. V φ · φ φ φ φ φ φ φ φ φ
At this point in the process, the outer layers are thermally bonded and have no openings therein as shown in Figures 1 and 2. The central layer or layers 30 of the belt 130 are perforated because they have been pushed away by the protrusions 116 in the gap 106.
The laminate web 10 can be further processed by creating slotted holes at all points projecting from the laminate web perpendicular to the axis I of the joint locations 50. It is in this manner that the open region of the web is formed. 9 and 10, the I axis is generally parallel to the machine direction MD of the web being processed. Hence the elongation in cross section of the CD to. the parts that are connected, cause. 50 will rupture and open to form slotted holes in the belt.
One way of forming slit-like openings on the belt is by passing the belt through a gap 130 formed by an incremental pulling system 132 that uses opposing pressure applicators 134, 136 having three-dimensional surfaces that are at least partially complementary to each other. Tensioning of the laminate web can be accomplished by other methods known in the art, including other tensioning or even hand-stretching, but to achieve a uniform level of tension throughout the web, and especially when they are. localized voltage differentials are desired. the incremental pull-out system 132 described herein.
FIG. 12 is a partial enlarged view of an incremental pulling system 132 that includes incremental pulling rollers 134 and 136. The incremental pulling roller 134 has a plurality of teeth 160 and corresponding grooves 161- that extend around the entire periphery of the roller 134.
The incremental take-up roller 136 includes teeth 162 and

The teeth of each roller are generally triangular in shape as shown in Figure 13. they may be slightly rounded if desired for some effects in the finished strip.
Giant. 13 shows a portion of the interlocking teeth 160 and 162 of rollers 134 and 134, respectively. 136. The term tooth pitch as used herein refers to the distance between the vertices of adjacent teeth. The pitch of the teeth may be 0.508 mm to 7.620 mm (0.02 to 0.30) and is preferably in the range of 1.25 mm to 0.50 mm. 3.81 mm (0.05 to 0.15). The tooth height or depth is measured from the tooth base to the tooth tip and is preferably the same for all teeth. The height of the teeth can. be in the range of 2.54 mm to 22.86 mm (0.10 to 0.90) and is preferably 6.35 mm to 12.7 mm (0-, 25 to 0.50)
The teeth 160 in one cylinder may be offset by half the pitch relative to the teeth 162 in the other cylinder such that the teeth of one cylinder, e.g., teeth 160-, fit into a depression, i.e., a depression 163-, between the teeth in the opposite cylinder. The offset allows the opposing rollers to engage when engaged or when they engage a working position with each other. In a preferred embodiment, the teeth of the respective rollers only partially engage one another. The degree to which the teeth on the opposing rollers fit together is referred to herein as Depth of Engagement (abbreviated DOE) as seen in Figure 13, DOE E being the distance between. the position given by the plane Pl<sub>7</sub> where are they. tooth tips on respective cylinders in the same plane (0% engagement) to the position indicated by plane P2, where the tooth tips of one cylinder extend inward beyond plane P1 into a depression on the opposite cylinder.

In other embodiments, the teeth of the interlocking rollers need not be aligned to the depressions of the opposite cylinder, i.e., the teeth may be out of phase with the depressions to some extent, from a slight deflection to a large deflection.
As the laminate web 10 having the melt bonded sites 50 passes through the incremental pulling system 132, the laminate web 10 may be subjected to CD stretching across the machine, causing the laminate web 10 to stretch in the CD direction across the machine. Alternatively or additionally, the laminate web may be 1.0. tensioned in MD direction along the machine. The tensioning force exerted on the laminate web 10 can be adjusted, i. adjusting the DQE to cause the hot melt joints 50 to separate or rupture, thereby forming a plurality of slotted holes 60 that are at the hot melt joints 50 in the laminate strip 10. Portions of the hot melt joints of the laminate strip 10 but. they remain as shown by the portions 62 in FIG. 4, thereby keeping the nonwoven web in a coherent state even after the fusion bonding sites break. After being subjected to the tensioning force exerted by the incremental pulling system 132, the laminate web 10 has a plurality of slotted apertures 60 that coincide with the fusion bonding points 50 of the laminate web. As noted, a portion of the peripheral edges of the slotted apertures 60 includes remnants 62 of the melting joints 60. The remnants 60 are believed to help withstand further tearing or delamination of the laminate web.
Instead of two substantially identical rollers 134 and 136, one or both rollers may be configured to produce stretch and further patterning. For example, one or both of the rollers may be modified.

such that they have a plurality of uniformly spaced thin, planar channels 24 6 on the surface of the roll, as shown in roller 236 in Fig. 14, in the teeth. Fig. 14 is an enlarged view of an alternative incremental pulling system 232 including incremental withdrawal rollers 234 and 236. The incremental withdrawal roller 234 has a plurality of teeth 260 and corresponding grooves 261 that extend around the entire periphery of the cylinder 23.4. The incremental withdrawal roller 236 has a plurality of teeth 262 and a plurality of corresponding grooves 263. The teeth 260 on the roller 234 engage or engage the grooves 263 on roller 236 while the teeth 262 on roller 236 engage or engage grooves 261 on roller 234. The teeth on one or both rollers may have formed channels 246 for example by machining such that areas of undeformed laminate sheet material may remain after tensioning. A suitable patterned cylinder is described in U.S. Pat. No. 5,518,801.
Similarly, the incremental extraction can be performed by interlocking rolls oriented in accordance with FIG. 15. Such rolls have a series of ridges. 36Q ,. 362 and depressions 361<sub>r</sub> 363<sub>r</sub> The ridges form triangular teeth on the surface of the cylinder.

The resulting feel and appearance make such fabric belts ideal for use on the articles of the present invention.
Useful component:
The articles of the present invention further comprise a utility component that is disposed adjacent to the laminate strip. Because the products of the present invention are suitable for use in a variety of areas, eg, personal hygiene, household cleaning, etc., the utility component may be selected from the group consisting of skin cleansing ingredients, conditioning ingredients, cosmetic ingredients, cleansing ingredients, polishing ingredients. and combinations thereof.

The detergent cleaners are preferably foaming detergents. As used herein, a foaming detergent means a detergent that when combined with water and mechanically stirred to form a foam. Such detergents are advantageous because increased foaming is important for consumers as an indication of cleaning efficiency. In some personal care embodiments, the detergents or combinations thereof are preferably delicate. As used herein, the term "fine" means that detergents as well as articles of the present invention exhibit fineness such that they are at least finer than conventional dice soap matrices, which generally include a combination of natural soap and synthetic detergents, e.g., Lever 2000® and Zest®. Methods for measuring the fineness or irritability of detergent-containing products are based on the skin barrier destruction test. In this test, the finer the detergent, the less the skin barrier is destroyed. Skin barrier destruction is measured by the relative amount of radioisotope (tritium) labeled water (3H-H).<sub>2</sub>O) that passes from the test solution through the epidermis of the skin to the physiological buffer contained in the diffusate chamber. This test is described by TJ. Franz in J. Invest. Dermatol., 1975, 64, pp. 190-195 and in U.S. Pat. No. 4,673,525. Other test methodologies for determining the fineness of detergents well known to those skilled in the art may also be used.
A wide variety of foaming detergents can be used herein, including those selected from the group consisting of anionic foaming detergents, nonionic foaming detergents, cationic foaming detergents, amphoteric foaming detergents, and mixtures thereof.
Anionic foaming detergents:
• ·
Examples of anionic foaming detergents useful in the cleaning component of the article are described in: McCutcheon Detergents and Emulsifiers, North American edition (1986), published by Allured Publishing Corporation; McCutcheon: Functional Materials, North American edition (1992); and U.S. Pat. No. 3,929,678.
Detergents can be used here. non-limiting examples of anionic foaming agents include those selected from the group consisting of alkyl and alkyl ether sulfates, sulfated monoglycerides, sulfonated olefins, alkylarylsulfonates, primary or secondary alkanesulfonates, alkylsulfosuccinates, acyl sulfonate esters, acyltauronate esters, acyltauronate esters , sulfonated fatty acids, alkyl phosphates, ethoxylated alkyl phosphates, acylglutamates, acyl sarcosinates, alkylsulfoacetates, acylated peptides, alkyl ether carboxylates, acylalkylates, anionic fluorodetergents, and combinations thereof. Combinations of anionic detergents can be effectively used in the present invention.
Anionic detergents for use in the cleansing component include alkyl sulfates and alkyl ether sulfates. These materials have the corresponding formulas R<sup>X</sup>O-SC3M and R<sup>1</sup> (CH2H4O) χ-Ο-δΟβΜ in which R<sup>1</sup> is a saturated or unsaturated, branched or unbranched alkyl group of 8 to 24 carbon atoms, x is 1 to 10, and M is a water-soluble cation such as ammonium, sodium, potassium, magnesium, triethanolamine, diethanolamine and monoethanolamine. Alkyl sulfates are generally made by sulfating monohydric alcohols having from 8 to 24 carbon atoms using sulfur trioxide or other known sulfation techniques. Alkyl ether sulfates are generally made as condensation products of ethylene oxide and monohydric
<img file="CZ20021933A3_D0005.tif" />
of alcohols having from 8 to 24 carbon atoms which are then sulfated. These alcohols may be derived from fats, e.g., coconut oil or tall oil, or may be synthetic. Specific examples of alkyl sulfates that can be used in the cleaning component are sodium, ammonium, potassium, magnesium, or TEA salts of lauryl or myristyl sulfate. Examples of alkyl ether sulfates that can be used include ammonium, sodium, magnesium or TEA laureth-3-sulfate.
Another suitable class of anionic detergents are sulfated monoglycerides of formula R<sup>X</sup>CO-O-CH 2 -C (OH) H-CH<sub>2</sub>-O-SO<sub>3</sub>M, where R<sup>1</sup> is a saturated or unsaturated branched or unbranched alkyl group of 8 to 24 carbon atoms, and M is a water-soluble cation such as ammonium, sodium, potassium, magnesium, triethanolamine, diethanolamine and monoethanolamine. Generally, they are made by reacting glycerine with fatty acids having from 8 to 24 carbon atoms to form a monoglyceride and subsequent sulfation of the monoglyceride with sulfur trioxide. An example of a sulfated monoglyceride is sodium cocomonoglyceride sulfate.
Other sulfonates of suitable anionic detergents include the R-shaped olefin<sup>1</sup>S03M, where R<sup>1</sup> is a monoolefin having 12 to 24 carbon atoms and M is a water-soluble cation such as ammonium, sodium, potassium, magnesium, triethanolamine, diethanolamine and monoethanolamine. These compounds can be produced by sulfonating the alphaolefins with non-complex sulfur trioxide followed by neutralization of the acidic reaction mixture under conditions such that the sultones formed in the reaction are hydrolyzed to give the corresponding hydroxyalkane sulfonate. An example of a sulfonated olefin is C 1-6<sub>4</sub>/Whose<sub>6</sub>-alphaolef sodium sulfonate.
Other suitable anionic detergents are linear alkylbenzene sulfonates of formula R<sup>1</sup>CgH<sub>4</sub>-SO<sub>3</sub>M, where R<sup>1</sup> it is a saturated or unsaturated alkyl group of 8 to 24 carbon atoms and M is a water-soluble cation such as ammonium, sodium, potassium, magnesium, triethanolamine, diethanolamine and monoethanolamine.

Cosmetic component:
In the field of personal care, the utility of the article is suitable for providing therapeutic or aesthetic benefits to the skin or hair by imposing not only conditioning agents, but also various agents including, but not limited to, anti-acne active agents such as deodorants or antiperspirants, wrinkle formation, antimicrobial, antifungal, anti-inflammatory, as a topical anesthetic, artificially producing a tan-like appearance and accelerating tan, anti-viral agents, sunscreen enzymes, antioxidant, skin peeling agents and combinations thereof. These additional active ingredients are further detailed below in the optional additional ingredients section below
Other cosmetic ingredients that are suitable for inclusion in the subject article are bases, reds, blemishes, blends, and other typical cosmetic coloring products. Such ingredients actually result in an article of the present invention that is suitable for makeup applications.
It is also to be understood that a preferred component may comprise a combination of a cleaning component, a conditioning component, a cosmetic component, a cleaning component, a polishing component, etc. in such a way as to form a uniform preferred component with indistinguishable impurities and multiple functions.
Cleaner:
For use in household cleaning, the useful ingredient of the product is suitable to provide benefits in cleaning domestic surfaces, for example hard surfaces such as kitchen countertops, walls, washbasins, bathtubs, floors, windows, etc. Such preferred ingredients are then referred to as cleaning ingredients. . Such cleaning components are preferably liquids since they can be easily applied to contaminated surfaces in a uniform and concentrated manner. However, solid cleansing components are also acceptable when dissolved in water or other liquid in use. The cleaning components of the present invention include a safe and effective amount of a relatively hydrophilic polymer that will render the treated surface hydrophilic. This increase in hydrophilicity provides an improved final appearance by coating the water on the surface or by spreading water over the surface, and this effect is preferably seen when the surface is rewetted and even when it is subsequently dried after rewetting.
In those products of the present invention that are intended to be used as a daily shower product, the coating effect is particularly notable since most of the surfaces treated are vertical surfaces. Thus, advantages have been observed on glass, ceramics and even more when wetting surfaces such as porcelain glaze. When the water evenly covers the surface or is spread over the surface, the formation of hard water spots that are formed after drying is minimized. In an article of the present invention that is intended to be used in the context of a floor cleaner, the polymer improves surface wetting and aids cleaning.
The polymeric property is advantageous because it extends the benefits of coating and cleaning. Another advantageous feature of the preferred polymers is that there is no residue after drying. Compositions comprising particularly preferred polymers dry more evenly on the floors and improve the end result with little or no haze.
Many materials can provide coatings and have the advantages of not staining, but particularly preferred materials are polymers that contain amine oxide hydrophilic groups. Polymers containing other hydrophilic groups, such as sulfonate, pyrrolidone and / or carboxyl groups, may also be used. Examples of desirable polysulfonate polymers include polyvinyl sulfonate and more preferably polystyrene sulfonate such as those sold by Monomer-Polymer Dajac (1675 Bustleton Pike, Feasterville, Pennsylvania 19053, USA. A typical formula is as follows:
[CH (C<sub>6</sub>H<sub>4</sub>SO<sub>3</sub>Na) -CH<sub>2</sub>] <sub>n</sub>-CH (C.<sub>6</sub>H<sub>5</sub>) -CH<sub>2</sub>wherein n is a number indicating the appropriate molecular weight as described below.
Typical molecular weights are from 10,000 to 1,000,000, preferably from 200,000 to 700,000. Especially preferred polymers.

Other materials may also provide mass and hydrophilicity, including cationic materials that also contain hydrophilic groups and polymers that contain multiple ether bonds. Cationic materials include cationic sugar and / or starch derivatives, and typical block copolymer detergent surfactants based on mixtures of polypropylene oxide and ethylene oxide are representative of polyether materials. However, the polyether materials are less massive.
Particularly preferred polymers include water-soluble amine oxide moieties.
Preferred polymers include water-soluble amine oxide moieties. It is believed that the partial positive charge of the amine oxide group can act to adhere the polymer to the surface of the substrate that is on the surface, allowing water to more easily spread into the layer. The amine oxide moiety can also bind through hydrogen with hard surface substrates such as ceramic tiles, glass, fiberglass, porcelain glaze, linoleum, wax-free tiles and other hard surfaces commonly used in consumer homes. To the extent that the anchoring of the polymer aids in better layering, higher molecular weight materials are preferred. Improved molecular weight improves the efficiency of amine oxide-based polymers. Particularly preferred polymers of the invention have one or more monomer units that contain at least one N-oxide group. At least 10%, preferably more than 50%, more preferably more than 90% of the polymer-forming monomers comprise an amine oxide group. These polymers may be described by the general formula: P (B), wherein each P is selected from homopolymerizable and fused to form preferably a vinyl moiety, copolymerizable moieties that have a polymer backbone, such as C (R)<sub>2</sub>-C (R)<sub>2</sub>wherein each R is hydrogen, C1-C<sub>12</sub> (with benefit

Preferred polymers that can be used in the cleaning component have the unexpected property of being massive without leaving a visible residue that makes the surface substrate unattractive to the consumer.

High molecular weight polymers often allow the use of lower levels of wetting polymer, which can provide benefits in floor cleaner applications. The desired molecular weight range of the polymers useful in the present invention is in contrast to the prior art disclosed for polycarboxylate-based polystyrenesulfonate polyether additives which provide molecular weights in the range of 400,000 to 1,500,000. The low molecular weights of the particularly preferred polyamine oxide polymers of the present invention are due to the greater difficulty in producing the higher molecular weight polymers.
The level of amine oxide polymer will normally be less than 0.5%, preferably from 0.005% to 0.4%, even more preferably from 0.01% to 0.3% by weight. mixture or solution for end use.
Some non-limiting examples of homopolymers and copolymers that can be used as the water-soluble polymers of the present invention are: copolymer of adipic acid and epoxypropyldiethylenetriamine, polyvinyl alcohol, copolymer of methacryloylethyl betaine and methacrylates, copolymer of ethyl acrylate, methyl methacrylate, methacrylic acid and acrylic acid, polyylamine resins and polyquaternary amine resins, poles (ethenylformamide), poles (ethenylformamide) poles (vinyl alcohol-to-12% vinylamine), poles (vinyl alcohol-to-6% vinylamine hydrochloride) and poles (vinyl alcohol-to-12% vinylamine hydrochloride). Preferably said copolymers or homopolymers are selected from the group consisting of copolymers of adipic acid and dimethylaminohydroxypropyldiethylenetriamine, poly (vinylpyrrolidone / dimethylaminoethyl methacrylate), polyvinyl alcohol, copolymer of ethyl acrylate, methyl methacrylate, methacrylic acid, methacrylic acid, methacrylic acid, methacrylic acid, methacrylic acid and methacrylic acid. polyquaternary amine resins, poles (ethenylformamide), poles (vinylamine) hydrochloride, poles (vinyl alcohol-to-6% vinylamine), poles (vinyl alcohol-to 12% vinylamine hydrochloride).
The polymers useful in the cleaning component of the present invention can be selected from the group consisting of copolymers of hydrophilic monomers. The polymer may be linear random or block copolymers and mixtures thereof. The term hydrophilic is used herein consistent with a standard meaning having affinity for water. As used herein in relation to monomer units and polymeric materials, including copolymers, hydrophilic means substantially water-soluble. In this regard, substantially water-soluble will mean a material that is soluble in distilled (or equivalent) water at 25 ° C at a concentration of about 0.2% by weight. and are preferably soluble at about 1% water. The terms soluble, solubility and the like for this purpose correspond to the maximum concentration of monomer or polymer, as appropriate, that can be dissolved in water or other solvents to form a homogeneous solution as understood by those skilled in the art.
Non-limiting examples of useful hydrophilic monomers are unsaturated organic mono- and polycarboxylic acids such as acrylic acid, methacrylic acid, crotonic acid, maleic acid and its semi-esters, itaconic acid, unsaturated alcohols such as wine alcohol, allyl alcohol, polar vinyl heterocycles such as vinylcaprolactam , vinylpyridine, vinylimidazole, vinylamine, vinylsulfonate, unsaturated amides such as acrylamides, e.g. N, N-dimethylacrylamide, N-t-butylacrylamide, hydroxyethyl methacrylate, dimethylaminoethyl methacrylate, acid salts and amines listed above and the like, and mixtures thereof. Some preferred hydrophilic monomers are acrylic acid, methacrylic acid, N, N-dimethylacrylamide, N, N-dimethylmethacrylamide, Nt-butyl acrylamide, dimethylaminoethyl methacrylate and mixtures thereof.
Polycarboxylate polymers are those polymers that are formed by polymerizing monomers, at least some of which contain carboxyl functionality. Common monomers include acrylic acid, maleic acid, ethylene, vinylpyrrolidone, methacrylic acid, methacryloylethyl betaine, etc. Particularly preferred polymers for weight are those having a higher molecular weight. For example, polyacrylic acid having a molecular weight below 10,000 is not exactly mass and therefore does not normally ensure hydrophilicity after three wetting of all compositions, although with higher levels or certain surfactants such as amphoteric or zwitteronic detergent surfactants, the molecular weights can be up to down to 1000 giving certain results. In general, polymers should have a molecular weight of more than 10,000, preferably more than 20,000, even more preferably more than 300,000 and even more preferably more than 400,000. It has also been found that higher molecular weight polymers, for example those having weights of more than 3,000,000 are extremely difficult to formulate and are less effective in providing soil protection benefits than low molecular weight polymers. Accordingly, the molecular weight should normally be from 20,000 to 3,000,000, preferably from 20,000 to 2,500,000, more preferably from 300,000 to 2,000,000, even more preferably from 400,000 to 1,500,000, particularly for polyacrylates.
An advantage for some polycarboxylate polymers is the effectiveness of the detergent component in such polymers. Although such polymers interfere with film formation or striation, like other detergent ingredients, they provide enhanced cleaning performance for typical particulate-containing impurities that are difficult to remove.
Some polymers, especially polycarboxylate polymers, thicken mixtures that are aqueous liquids. This may be desirable, but when the compositions are placed in containers with a trigger spray device, the compositions are not desirable as dense as they would require excessive trigger pressure. Shear viscosity should generally be less than about 200 cP (2 dynes / cm)<sup>2</sup>), preferably less than 100 cP (1 dynes / cm)<sup>2</sup>), more preferably less than 50 cP (0.5 dyn.s / cm<sup>2</sup>). However, it may be desirable to have dense compositions to prevent the mixture from flowing to the surface, especially vertical surfaces.
Non-limiting examples of polymers for use in the present invention include the following: vinylpyrrolidone-acrylic acid polymer sold under the name Acrylidone® by ISP and acrylic acid polymer marketed under the name Accumer® by Rohm & Haas. Other suitable materials include sulfonated polystyrene polymers sold under the name Versaflex ® sold by the National Starch and Chemical Company, especially Versaflex 7000.
The level of polymeric material will normally be less than 0.5%, preferably 0.01% to 0.4%, even more preferably from 0.01% to 0.3%. In general, low molecular weight materials, such as low molecular weight polyacrylic acid, such as those having molecular weights below 10,000, and especially around 2000, do not provide good non-staining benefits after rewetting, especially at low levels, such as 0.02%. Only more efficient materials at low levels should be used. In order to use low molecular weight materials, weight should be increased, for example by adding groups that provide improved surface attachment, such as cationic groups, or materials of na 4 * 4 should be used.

A particularly preferred polymer is polyvinylpyridine n-oxide.
Another embodiment of the cleaning component comprises an effective amount of a detergent surfactant in place of the polymer described above. Suitable detergent surfactants include those foams described above as suitable for inclusion in the cleansing component.
Particularly preferred surfactants for use in the present invention are the alkyl polysaccharides described in U.S. Patent Nos. 5,776,872, 883,059, 5,883,062 and 5,906,973.
Suitable alkylpolysaccharides for use in the present invention are described in U.S. Pat. No. 4,565,647 having a hydrophobic group containing from 6 to 30 carbon atoms, preferably from 10 to 16 carbon atoms, and a polysaccharide, for example a polyglycoside having a hydrophilic group. For acidic or alkaline cleaning compositions or solutions suitable for use in non-rinsing methods, the preferred alkyl polysaccharide preferably includes a wide distribution of chain lengths, such as those that provide the best combination of wetting, cleansing, and low residue after drying. This broad distribution is defined such that at least 50% of the chain length mixture comprises from 10 carbon atoms to 16 carbon atoms. Alkyl • 4 ♦ * 4 * 44 44

44 The alkyl polysaccharide group is preferably composed of mixtures of chain lengths, preferably of 6 to 18 carbon atoms, more preferably of 8 to 16 carbon atoms, and a hydrophilic group containing from 1 to 1.5 carbohydrate, preferably glucoside groups per molecule. This broad distribution of chain lengths is defined by at least 50% of the chain length mixture, comprising from 10 carbon atoms to 16 carbon atoms.<sub>8</sub> to C<sub>16</sub> is highly desirable compared to a narrower range of chain length mixtures and especially to lower (e.g.<sub>8</sub> to Ci<sub>0</sub> or C<sub>8 to</sub> C<sub>12</sub>) chain length of alkyl polyglucoside mixtures. It is also found that preferred C<sub>8 </sub>up to C 16 alkylpolyglucoside provides much better perfume solubility over lower and narrower chain lengths of alkyl polyglucosides, as well as other preferred surfactants, including C<sub>8 </sub>to C14 alkyl ethoxylates. Any reducing carbohydrate containing 5 or 6 carbon atoms can be used, for example glucose, galactose and galactosyl moieties can be substituted for glucosyl moieties (optionally, the hydrophobic moiety is attached at the 2-, 3-, 4-, etc. positions, giving glucose or galactose versus glucoside or galactoside). The linkages within the saccharides may be, for example, between position one of the other saccharide units and positions 2, 3, 4, or 6 on the preceding saccharide units. The glycosyl is preferably derived from glucose.
Alternatively, and less desirably, there may be a polyalkylene oxide chain linking the hydrophobic moiety and the polysaccharide moiety. A preferred alkylene oxide is ethylene oxide. Typical hydrophobic groups include alkyl groups, either saturated or unsaturated, branched or unbranched, containing from 8 to 18, preferably from 10 to 16 carbon atoms. The alkyl group is preferably a straight chain saturated alkyl group. The alkyl group may contain up to 3 hydroxyl groups or the polyalkylene oxide chain may contain up to 10, preferably less than 5
4 · ··· 4 alkylene oxide moieties. Suitable alkyl polysaccharides are octyl, nonyldecyl, undecyldodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, heptadecyl and octadecyl, di-, tri, tetra-, penta- and hexaglucosides or galactose. Suitable mixtures include coconut oil alkyl, di-, tri-, tetra- and pentaglucosides and tallow alkyl-, penta- and hexaglucosides.
To prepare these compounds, an alcohol or an alkylpolyethoxy alcohol is first formed and then reacted with glucose or a source of glucose to form a glucoside (attachment at position 1). Further glycosyl units can then be attached between their 1-position and the preceding glycosyl units at position 2, 3, 4 or 6, preferably at position 2.
In alkyl polyglycosides, alkyl moieties may be derived from conventional sources such as fats, oils or chemically produced alcohols, while their sugar moieties are formed from hydrolysed polysaccharides. Alkyl polyglycosides are the condensation product of fatty alcohol and sugars such as glucose with a number of glucose units defining relative hydrophilicity. As discussed above, the sugar units may additionally be alkoxylated either before or after reaction with fatty alcohols. Such alkyl polyglycosides are described in detail, for example, in WO 86/05199.

C<sub>8</sub> to Ci<sub>6</sub> alkyl polyglycosides are commercially available, for example, as Simusol® detergents from Seppic Corporation, 75 Quai d'Orsay, 75321 Paris, Cedex 7, France, and as Glucopon® 425 available from Henkel. However, it has been found that the purity of an alkyl polyglucoside may also affect functionality, particularly the end result for certain applications, including daytime shower product technology. In the present invention, preferred alkyl polyglucosides are those which have been sufficiently purified for use in personal cleansing. Most preferred are cosmetic types of alkyl polyglucosides, especially C<sub>8</sub> to C 18 alkyl polyglucosides such as Plantaren 2000 ®, Plantaren 2000 N ® and Plantaren N UP ®, which are available from Henkel Corporation (Postfach 101100, D 40191 Dusseldorf, Germany). Such detergents would thus also be advantageous for use in the cleaning component when the article is used for personal care applications.
In the context of applications to floors, kitchen countertops, walls, etc., another class of preferred nonionic surfactants are alkyl ethoxylates. The alkyl ethoxylates of the present invention are either linear or branched and contain from 8 carbon atoms to 14 carbon atoms and from 4 ethylene oxide units to 25 ethylene oxide units. Examples of alkyl ethoxylates include Neodol® 91-6, Neodol 91-8® supplied by Shell Corporation (PO Box 2463, 1 Shell Plaza,
Houston, Texas), and Alfonic® 810-60 supplied by Vista Corporation, (900 Threadneedle PO Box 19029, Houston, TX, USA). More preferred surfactants are alkyl ethoxylates of carbon atoms and from 4 to 8 These surfactants comprising from 9 to 12 ethylene oxide units.
They offer excellent cleaning benefits and work synergistically with the desired hydrophilic polymers. The most preferred alkyl ethoxylate is C11EO5, available from Shell Chemical Company under the trademark Neodol® 1-5. This surfactant provides desirable moisturizing and cleansing properties and can be advantageously combined with preferred C<sub>8</sub> to C<sub>16</sub> an alkylpolyglucoside in a matrix comprising the humectant polymers of the present invention. Without wishing to be bound by theory, it is believed that C<sub>8</sub> up to C 16 alkylpolyg lucoside can provide excellent end result (ie reduced haze) in compositions that additionally contain a preferred alkyl ethoxylate, especially when a preferred alkyl ethoxylate is required for excellent purification. It has been found that preferred C<sub>8</sub> The alkyl to polyglucoside also improves the solubility of the perfume compositions comprising alkyl ethoxylates. Higher levels of perfume can be beneficial by being more accepted by customers.
More preferred detergent surfactants are selected from the group consisting of alkyl polysaccharide detergents having an alkyl group containing from 8 to 18 carbon atoms, more preferably from 8 to 16 carbon atoms, and from one to four, preferably from one to 1.5 carbohydrate moieties per molecule or a combination consisting of alkyl polysaccharide detergent surfactants having an alkyl group containing from 8 to 18 carbon atoms, more preferably from 8 to 16 carbon atoms and from 1 to 4, preferably from 1 to 1.5 carbohydrate moieties per molecule together with an alkyl ethoxylate comprising from 8 to 16 carbon atoms and from 4 to 25 oxyethylene units, and combinations thereof.
The cleaning components are prepared with relatively low levels of active ingredients. These compositions generally include sufficient surfactant and optional solvent, as discussed below, which are effective as detergent compositions. 9 9 9 9 9 9 99 99 9 9 99 9 9 9 9 9 9 9 999 9 999 9 99 99 9999 on hard surfaces, but remain economical. Therefore, they generally contain from 0.005% to 0.5% by weight. a surfactant mixture, preferably an alkylpolyglycoside and / or C<sub>8</sub> to C<sub>i4</sub> an alkyl ethoxylate surfactant, more preferably from 0.01% to 0.4% surfactant, and even more preferably from 0.01% to 0.3% surfactant. It has been found that the use of low rather than high levels of surfactant is advantageous in terms of overall end results. It has also been found that when the primary surfactant system comprises preferred alkyl ethoxylates, the resulting haze is alleviated by specific surfactant aids. Preferred co-surfactants are C<sub>8 </sub>sulfonate and Poly-Tergent CS-1.

Methodology of moisture retention measurement:
As described above, in some cases the products of the present invention are considered to be substantially dry. As used herein, the term substantially dry means that the articles of the present invention exhibit a moisture retention of less than 0.95 g / m 2<sup>2</sup>, preferably less than 0.75 g / m 2<sup>2</sup>even more preferably less than 0.5 g / m 2<sup>2</sup>even more preferably less than 0.25 g / m 2<sup>2</sup>even more preferably less than 0.15 g / m 2<sup>2</sup> and most preferably less than 0.1 g / m 2<sup>2</sup>. The moisture retention indicates how dry the users feel when they touch certain articles of the present invention as compared to the moisture feel of wet products.
On the other hand, there are articles of the present invention that are substantially wet. As used herein, the term & quot; substantially wet & quot; means that the consumer is perceived to be wet when touched. This means that the products have a moisture retention greater than 0.95 g / m<sup>2</sup>.
In order to determine the moisture retention of the subject articles and other substrate disposable articles, the following devices and materials are required:
Bounty Procter & Gamble Wipes SKU 37000 63037 white paper
The basis weight is 42.14 g / m<sup>2</sup>
Balance Accuracy to 0,0 g
Lexan Thickness 0.5
Large enough to completely cover samples and weights of 1000 g
Weights 2000 g weights or a combination equal to 2000 g
Then weigh two paper towels separately and record each weight. One paper napkin is placed on a flat surface (for example, a lab table). A sample of the product is placed on this napkin. A second paper napkin is placed on a sample of the article. Then Lexan is placed on it and then 2000 g of weight on the product sample layers. Wait 1 minute. After 1 minute, weights and Lexan are removed. Weigh the top and bottom paper tissues and record their weight.
The moisture retention is calculated by subtracting the initial weight of the paper towels from their final weight (after 1 minute) for both the top and bottom paper towels. The weight differences obtained for the upper and lower wipes are added together. Assuming multiple products are tested, the overall weight differences are averaged to obtain moisture retention.

Organic cleaning solvent:
The cleaning component of the disclosed disposable articles may comprise an effective amount of one or more organic cleaning solvents, generally not less than 0.25%, more preferably at least 0.5%, even more preferably 3.0% and not more than 7%, more preferably 5%. % cleaning component.
The surfactant provides cleaning or wetting even in the absence of a hydrophobic cleaning solvent, but cleaning can normally be further improved by using a genuine organic cleaning solvent. By organic cleaning solvent is meant an agent that aids the surfactant to remove impurities such as those normally found in a bathroom. The organic cleaning solvent may also be involved in forming the viscosity, if desired, and in increasing the stability of the composition. Mixtures containing<sub>8</sub> to Ci<sub>6 </sub>alkylpolyglucosides and C<sub>8</sub> to C 11 alkyl ethoxylates also have less soap bubble formation when a solvent is present. Thus, by simply controlling the amount of hydrophobic solvent in the formulation, the soap profile can be largely controlled.
Such solvents typically have a terminal hydrocarbon chain C<sub>3</sub> to C<sub>6</sub> attached to one to three moieties of ethylene glycol or propylene glycol to ensure an appropriate degree of hydrophobicity and preferably surface activity. Examples of commercially available hydrophobic cleaning solvents based on ethyl glycol chemistry include monoethylene glycol hexyl ether (Hexyl Cellosolve®, available from Union Carbide). Examples of commercially available hydrophobic cleaning solvents based on propylene glycol chemistry include
114 dipropylene glycol and tripropylene glycol derivatives of propyl alcohol and butyl alcohol, available from Areo Chemical, 3801 West Chester Pike, Newtown Square, PA 19073, USA, and Dow Chemical (1691 N. Swede Road, Midland, Michigan, USA) under the trade names Arcosolv ® and Dowanol®.
In the context of the present invention, preferred solvents are selected from the group consisting of monopropylene glycol mono propyl ether, dipropylene glycol monopropyl ether, monopropylene glycol monobutyl ether, dipropylene glycol monobutyl ether, dipropylene glycol monobutyl ether, ethylene glycol monobutyl ether, ethylene glycol monobutyl ether, ethylene glycol monobutyl ether, ethylene glycol monobutyl ether. Butyl includes both normal butyl, isobutyl and tertiary butyl groups. Monopropylene glycol and monopropylene glycol monobutyl ether are the most preferred cleaning solvents and are available under the trade names Dowanol DPnP® and Dowanol DPnB®. Dipropylene glycol mono-t-butyl ether is commercially available from Areo Chemical under the trade name Arcosolv PTB®.
The amount of organic cleaning solvent may vary depending on the amount of other components present in the composition. Hydrophobic cleaning solvent normally helps ensure good cleaning, as is the case with floor cleaner applications.
When cleaning indoors, the solvent may cause undesirable small droplets to be inhaled. Therefore, it is desirable that the mixtures or solutions to be used in such spaces be substantially, more preferably completely free of such solvents.

The cleaning component of the present articles may comprise a small amount of anionic or nonionic detergent surfactants. Such anionic surfactants typically include a hydrophobic chain having from 8 carbon atoms to 18 carbon atoms, preferably from 8 carbon atoms to 16 carbon atoms, and typically include a sulfonate or carboxylate hydrophilic group. Generally, the level is optional, e.g.

In the context of flooring products, kitchen countertops and other surface applications, the choice of surfactant adjuvant can be critical both in choice of type and level. It has been found that cleaning components comprising C<sub>8</sub> to Ci<sub>4</sub> alkyl ethoxylates may have low C levels<sub>8</sub> sulfonate to improve the end result by producing a tinting effect. Tinting means improving the appearance of the final product by having less turbidity. If C<sub>8 </sub>sulfonate present, preferably in an amount of 1:10 to 1: 1 by weight based on the primary surfactant (s). C<sub>8</sub> the sulfonate is commercially available from Stepan under the trade name Bio-Terge PAS-8® as well as from Witco Corporation under the trade name Witconate NAS-8®. Another excellent tinting surfactant which is preferred in the present invention is Poly-Tergent CS-1, which is available from BASF. If present, Poly-Tergent CS-1 is preferably used in a weight ratio of 1:20 to 1: 1 to the primary surfactant (s). Other surfactants that can be used, although less preferably, and generally at very low levels, include C<sub>8</sub> to Ci<sub>8 </sub>alkyl sulfonates (Hostapur SAS® from Hoechst,
Aktiengesellschaft, D-6230 Frankfurt, Germany), Cio to C<sub>14</sub>
116 linear or branched alkylbenzene sulfonates, C8 to C8<sub>15 </sub>alkylethoxycarboxylate detergent surfactants (Neodox® surfactants available from Shell Chemical Corporation), C<sub>10</sub> to C<sub>X4</sub> alkyl sulfates and ethoxy sulfates (e.g., Stepanol AM® from Stepan). The alkyl ethoxycarboxylates may advantageously be used at very low levels (0.01% or less) to dissolve the perfume. This may be an important advantage if low levels of active ingredient are needed for the present invention to be most effective as a household cleaning product.
Alternative nonionic detergent surfactants for use in the present invention are alkoxylated alcohols, generally comprising from 6 to 16 carbon atoms in the hydrophobic alkyl chain of the alcohol. Typical alkoxylation groups are a combination of propoxy or propoxy ethoxy. Such compounds are commercially available under the tradename Antarox® from Rhodia (POBox 425 Cranberry, New Jersey 08512) with a wide range of chain lengths and alkoxylation steps. Block copolymers of ethylene oxide and propylene oxide can also be used and are available from BASF under the trade name Pluronic®. Preferred nonionic detergent surfactants for use in the present invention are of the formula R (X)<sub>n</sub>H, wherein R is an alkyl chain having from 6 to 16 carbon atoms, preferably from 8 to 12, X is propoxy or a mixture of ethoxy propoxy groups, n is an integer from 4 to 30, preferably from 5 to 8. Other nonionic surfactants active agents that can be used include those derived from natural sources such as sugars and include C 8 to C 16 N alkyl glucosoamide surfactants. If present, the concentration of alternative nonionic surfactants is from 0.01% to 0.2%, more preferably from 0.01% to 0.1% by weight.

Monocarboxylic or polycarboxylic acids:
For the purpose of removing the soap and hard water stains, the cleaning component of the article may be acidified to a pH of from 2 to 5, more preferably around 3. The acidity is at least partially achieved by using one or more organic acids which then have less than 5, preferably less. Such organic acids may aid in the formation of phases for thickening, if necessary, as well as providing for the removal of hard water stains. Organic acids have been found to be very effective in removing hard water stains within the compositions of the present invention. Lower pH and the use of one or more suitable acids has also proven advantageous for disinfection purposes.
Examples of suitable monocarboxylic acids include acetic acid, glycolic acid or β-hydroxypropionic acid and the like. Examples of suitable polycarboxylic acids include citric acid, tartaric acid, succinic acid, glutaric acid, adipic acid, and mixtures thereof. Such acids are readily available commercially. Examples of more preferred polycarboxylic acids, especially non-polymeric polycarboxylic acids include citric acid (available from Aldrich Corporation, 1001 West Saint Paul Avenue, Milwaukee, Wisconsin, USA), a mixture of succinic, glutaric and adipic acid available from DuPont (Wilmington, Delaware, USA). ) sold as refined AGS di-basic acid, maleic acid (also available from Aldrich) and mixtures thereof.

Aroma agents:
The cyclodextrins can be used in the cleaning component of the present invention. As used herein, the term cyclodextrin includes all known cyclodextrins, such as unsubstituted cyclodextrins containing from 6 to 12 glucose units, especially alpha-cyclodextrin, beta-cyclodextrin, gamma-cyclodextrin, or derivatives or mixtures thereof. Alpha-cyclodextrin consists of 6 glucose units, beta-cyclodextrin consists of 7 glucose units, and gamma-cyclodextrin consists of 8 glucose units arranged in donut-shaped circles. The specific bonding and structure of the glucose units gives the cyclodextrins rigid, conical molecular structures with hollow interiors with specific volumes. The lining of each inner cavity is formed by hydrogen atoms and glycosidic bridging oxygen atoms. This surface is therefore relatively hydrophobic. The particular shape and physicochemical properties of the cavity allow the cyclodextrin molecules to be absorbed, ie, to form inclusion complexes with organic molecules or portions of organic molecules that may fit into the cavity. Many aroma-forming molecules can fit into the cavity, including many unpleasant smelling molecules and perfume molecules. Therefore, cyclodextrins, and in particular mixtures of cyclodextrins with cavities of different sizes, can be used to treat the aroma caused by a wide variety of organic aromatic materials, which may or may not contain reactive functional groups. Complexing between cyclodextrin and aromatic molecules takes place in the presence of water
119 it appears rapidly, but the extent of complex formation also depends on the polarity of the absorbed molecules. In aqueous solution, strongly hydrophilic molecules (those that are highly water soluble), if at all, only partially absorbed. Thus, cyclodextrin does not complex effectively with some very low molecular weight organic amines and acids when present to a small extent on a wet surface. However, when water is removed, for example, when a surface is dried, some low molecular weight organic amines and acids have greater affinity and more easily complex with cyclodextrins.
The cavities in the cyclodextrin in the solution of the present invention should remain substantially unfilled (cyclodextrin remains uncomplexed) when the cyclodextrin is in solution to allow the cyclodextrin to absorb various aromatic molecules when the solution is applied to the surface. The non-derivatized (normal) betacyclodextrin may be present in an amount up to its solubility limit of about 1.85% (about 1.85 g in 100 grams of water) at room temperature. Beta-cyclodextrin is not preferred for ingredients that call for a level of cyclodextrin higher than its water solubility limit. Non-derivatized beta-cyclodextrin is generally not preferred when the component contains a surfactant, as it affects the surface activity of most preferred surfactants that are compatible with the derivatized cyclodextrins.
The aqueous cleaning component of the present invention is preferably clear. The term clear as defined herein means transparent or translucent, preferably clear as water, i.e. transparent when viewed through a layer of less than 10 cm thickness.
The cyclodextrins used in the present invention are preferably highly water-soluble, such as alpha-cyclodextrin or its
120 derivatives, gamma-cyclodextrin or derivatives thereof, derivatized beta-cyclodextrins or mixtures thereof. Cyclodextrin derivatives consist mainly of molecules in which some OH groups are converted to OR groups. Cyclodextrin derivatives include, for example, those having short chain alkyl groups such as methylated cyclodextrins and ethylated cyclodextrins, wherein R is methyl or ethyl; those having hydroxyalkyl substituted groups such as hydroxypropylcyclodextrins or hydroxyethylcyclodextrins, wherein R is -CH<sub>2</sub>-CH (OH) - CH<sub>3</sub> or -CH<sub>2</sub>CH<sub>2</sub>-OH; branched cyclodextrins such as maltose-linked cyclodextrins; cationic cyclodextrins such as those containing 2-hydroxy-3- (dimethylamino) propyl ether, wherein R is CH<sub>2</sub>-CH (OH) - CH<sub>2</sub>-NCH3) <sub>2</sub>which is cationic at low pH; quaternary ammonium, e.g. 2-hydroxy-3- (trimethylammonio) propyl ether chloride, wherein R is CH<sub>2</sub>-CH (OH) —CH<sub>2</sub>—N<sup>+</sup> (CH3) <sub>3</sub>NO. 1<sup>-</sup>; anionic cyclodextrins such as carboxymethylcyclodextrins, cyclodextrinsulfates and cyclodextrinsuccinylates; amphoteric cyclodextrins such as carboxymethyl / quaternary ammonium cyclodextrins; cyclodextrins in which at least one glucopyranose unit has a 3-6-anhydrocyclomalt structure, e.g., mono-3-6-anhydrocyclodextrins and mixtures thereof as described in F.

Highly water soluble cyclodextrins are those having a water solubility of at least 10 g in 100 ml of water at room temperature, preferably at least 20 g in 100 ml of water, more preferably at least 25 g in 100 ml of water at room temperature. The availability of soluble, non-complex cyclodextrins is essential for effective control of aroma activity. Water-soluble cyclodextrins can exhibit more efficient aroma control than water-insoluble cyclodextrins when deposited on the surface.
Examples of preferred water-soluble cyclodextrin derivatives suitable for use in the present invention include hydroxypropyl-alpha-cyclodextrin, methylated alpha-cyclodextrin, methylated beta-cyclodextrin, hydroxyethyl-beta-cyclodextrin, and hydroxypropyl-beta-cyclodextrin. The hydroxyalkylcyclodextrin derivatives preferably have a degree of substitution of from 1 to 14, more preferably from 1.5 to 7, wherein the total number of OR groups per cyclodextrin is defined as the degree of substitution. The methylated cyclodextrin derivatives generally have a degree of substitution of from 1 to 18, preferably from 3 to 16. The known methylated beta-cyclodextrin is heptakis-2,6-di-O-methyl-D-cyclodextrin, commonly known as DIMEB, in which each glucose unit has about 2 methyl groups with a degree of substitution of about 14. A preferred, more commercially available, methylated beta-cyclodextrin is a randomly methylated beta-cyclodextrin, commonly known as RAMEB, having various degrees of substitution, normally about 12.6. RAMEB is more preferred than DIMEB because DIMEB affects the surface activity of preferred surfactants more than RAMEB. Preferred cyclodextrins are available, for example, from Cerestar USA Inc. and Wacker Chemicals (USA), Inc.
It may also be advantageous to use a mixture of cyclodextrins in the cleaning component. Such compositions absorb more aroma by complexing

Suitable silicone suds suppressors used herein include silicone and silica-silicone mixtures. Silicones can generally be represented by alkylated polysiloxane materials, while silica is normally used in fine forms, such as silica aerogels and xerogels and hydrophobic silicas of various types. In industrial practice, the term silicone has become a generic term that includes a number of relatively high molecular weight polymers containing siloxane units and hydrocarbon groups of various types. Silicone compounds have been widely described in the art, see, for example, U.S. Pat. Nos. 4,076,648, 4,021,365, 4,749,740, 4,983,316, and European Patents EP 150,872, EP 217,501 and EP 499,364.

Perfume:
One or more perfumes may also be included in the cleaning component of the articles of the present invention. As used herein, perfume includes perfume ingredients that are added primarily because of their olfactory advantageous properties, often accompanied by the use of a volatile organic solvent such as ethanol.
Most hard surface cleaning products contain some perfume in order to achieve an olfactory aesthetic advantage and to conceal the chemical aroma that the product may have. The main function of the small fraction of highly volatile, low-boiling (low boiling) perfume ingredients in these perfumes is to improve the scent of the product itself rather than achieve the subsequent scent of the cleaned surface, but some less volatile, high-boiling perfume ingredients can provide a fresh and clean impression of surfaces it is desirable that these components be stored and present on a dry surface.
Perfumes are preferably those which are more water soluble or volatile to minimize staining and film formation. Perfumes that can be used in the present invention are described in more detail in U.S. Patent 5,108,660, col. 8, lines 48 to 68, col. 9, lines 1 to 68 and col. 10 rows 1 to 24.
The perfume ingredients may be natural products such as essential oils, absolute, resinoids, resins, concretes, etc., and abeno synthetic perfume ingredients such as hydrocarbons, alcohols, aldehydes, ketones, ethers, acids, acetals, ketals, nitriles, etc., including saturated and unsaturated compounds, aliphatic, carboxyl and heterocyclic compounds.

Examples of such perfume compounds are: geraniol, geranylacetate, linalool, linalylacetate, tetrahydrolinalool, citronellol, citronellyl acetate, dihydromyrcenol, dihydromyrcenylacetate, terpineol, terpinylacetate, acetate, 2-phenylethanol, 2-phenylethyl acetate, benzyl alcohol, benzyl acetate, benzylsalicylate, benzyl benzylbenzylate, benzyl benzoate, cyclohexyl acetate, isononyl acetate, alpha-n-amyl cinnamic aldehyde, alpha-hexyl cinnamic aldehyde, 2-methyl-3- (p-tert-butylphenyl) propanal, 2-methyl-3- (p-isopropylphenyl) propanal, 3- (p-tert-butylphenyl) propanal, tricyclodecenyl acetate, tricyclodecenyl propionate, 4- (4-hydroxy-4-methylpentyl) 3- caclohexenecarbaldehyde, 4- (4-methyl-3-pentenyl) -3-cyclohexenecarbaldehyde, 4-acetoxy-3-pentyl tetrahydropyran, methyldihydrojasmonate, 2-n-heptyl-cyclopentanone, 3-methyl-2-pentyl-cyclopentanone, n- decanal, n-dodecanal, 9-decenol-1, phenoxyethylisobutyrate, phenylacetaldehyde diethyl acetal, phenylacetaldehyde diethyl acetal, geranonitrile, citronellonitrile, cedrylacetate, 3isocamphylcyclohexanol, cedrylether, isolongifolanone, aubepinenitrile, aubepine, heliotropin, coumarin, eugenol, vanillin, diphenyloxide, hydroxycitronellal, ionones, methylionones, hexyl, isomethylolizone, isomethylolizone, esomethylolone tetralin musk, isochroman musk, macrocyclic ketones, macrolactone musk, ethylenebrassylates, aromatic nitro musk. In this sense, the cleaning component typically comprises from 0.1% to 2% by weight of the composition. perfume ingredients, based on the cleaning component, or mixtures thereof, preferably from 0.1% to 1%. In a preferred peroxide-containing embodiment, the perfumes may be selected to be compatible with the oxidant.

LogP values have been published for many folders. For example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc. (Daylight CIS), Irvine, California, USA, contains many values, along with citations to the original literature. However, logP values are most easily calculated using CLOGP, which is also available from daylight CIS. This program also reports experimental LogP values when available in the Pomona92 database. The calculated logP (ClogP) is determined by the fragment approach of Hansch and Leo (cf. A.Leo in Comprehensive Medicinal Chemistry, Volume 4, C. Hansch, PGSammens, JB Taylor and CARamsden, Eds., P. 295, Pergamon Press, 1990). The fragment approach is based on the chemical structure of each component and takes into account the numbers and types of atoms, the conductivity of atoms and the chemical bonds. The ClogP values, which are the most reliable and widely used estimates for this physicochemical property, are preferably used in place of the experimental logP values in the choice of the basic solvent ingredients used in the present invention. Other methods that can be used to calculate ClogP include, for example, the Crippen fragmentation method as described in J. Chem. Inf. Comput. Sci., 27, 21 (1987); The Viswnadham fragmentation method as described in J. Chem. Inf. Comput. Sci., 29,163 (1989); and the Brot method as described in Eur. J. Med. Chem.-Chim. Theor. 19, 71 (1984).
Substances with detergent effects:

129 surfaces and have less film and smudge capability. Preferred detergent materials are the carboxylic acids described above in describing polycarboxylic acids. They include citric acid and tartaric acid. Tartaric acid improves cleaning and can minimize the problem of film formation or smudges that typically occur when detergents are added to hard surface cleaners.
The detergent agent is present in an amount that provides detergent effects and those detergent agents that are not part of the acidic pH adjustment described above are generally present in an amount of from 0.01% to 0.3%, more preferably from 0.005% % to 0.2%, and most preferably from 0.05% to 0.1%. cleaning agent.
Buffers:
The cleaning component of the article of manufacture may also contain other various additives known in the art about detergent compositions. Preferably, they are not used in an amount that causes unacceptable film and smear formation. Buffers are an important class of additions in this application. They appear mainly as a result of using a low amount of active ingredient. An ideal buffer system will maintain the pH within the desired narrow range without causing smears and film. Preferred buffers in the context of the invention are those that are highly volatile but can provide cleaning benefits in use. As such, they are advantageous in that they can be used in higher amounts than the corresponding buffers, which are less volatile. Such buffers tend to have a low molecular weight, i. less than 150 g / mol and generally contain no more than one hydroxy group. Examples of preferred buffers include ammonia, methanolamine, ethanolamine, 2-amino-2-methyl-1-propanol, 2-amino-2-methyl-1-propanol. ·· ··· ·
130 dimethylamino-2-methyl-1-propanol, acetic acid, glycolic acid and the like. Of these, ammonia, 2-dimethylamino-2-methyl-1-propanol and acetic acid are most preferred. When used, these buffers are present in an amount of 0.005% to 0.5%, with higher amounts being more preferred for more volatile chemicals.
Non-volatile buffers can also be used in the present invention. Such buffers can generally be used in lower amounts than preferred amounts because they tend to form stripes and film. Examples of such buffers include, but are not limited to, sodium carbonate, potassium carbonate, and bicarbonate, 1,3bis (aminomethyl) cyclohexane, sodium citrate, citric acid, maleic acid, tartaric acid, and the like. Particularly preferred is maleic acid as a buffer because of its tendency not to induce surface damage. Citric acid is also desirable because it provides antimicrobial benefits as a registered EPA active agent. In addition, detergents comprising polymers have been found to have an acidity to provide better wetting and provide a longer lasting coating, especially when the articles in question are used for daily shower cleaning. When used, the nonvolatile buffers are present in an amount of 0.001% to 0.05% by weight based on the weight of the composition.
Non-limiting examples of other ingredients are enzymes such as proteases, hydrotropes such as sodium toluene sulfonate, sodium cumene sulfonate and potassium xylene sulfonate; thickeners other than hydrophilic polymers in an amount of from 0.01% to 0.5%, preferably from 0.01% to 0.1%; appearance enhancing additives, such as colorants, provided that they do not adversely affect the formation of film or smudges.

Protective agents may also be used and may be required in many of the preferred ingredients of household care products, especially those containing large amounts of water. Examples of preservatives include bronopol, hexitidine sold by Angus Chemical, 211 Sanders Road, Northbrook, Illinois, USA. Other preservatives include cathone, - 2- (hydroxymethyl) (amino) ethanol, propylene glycol, sodium hydroxymethylaminoacetate, formaldehyde and glutaraldehyde, dichloro-s-triazine trione, trichloro-s-triazine trione and quaternary ammonium salts including dioctyldimethylammonium chloride, didecyldimethylammonium ammonium<sub>2</sub>-, C<sub>14</sub>and Ci<sub>6</sub>-dimethylbenzyl. Preferred preservatives include 1,2-benzisothiazolin-3-one and polyhexamethylenebiguanide, marketed by Avicia Chemicals, Wilmington, Delaware 19897, USA, and chlorhexide diacetate, marketed by Aldrich-Sigma, 1001 West Saint Paul Avenue, Milwaukee, WI 53233, USA , sodium pyrithione, sold by Arch Chemicals, 501 Merritt Seven, POBox 5204, Norwalk CT 06856,

The same preservatives may act to provide antibacterial control on the surface, but will generally require higher concentrations of from 0.005 to 0.1%. Other antibacterial agents may be present, including quaternary ammonium salts, but are not preferred in the context of the present invention at high concentrations, i.e., concentrations greater than 0.05%. It has been found that such compounds often interfere with the advantages of preferred polymers. In particular, quaternary ammonium surfactants tend to hydrophobically modify hard surfaces. Thus, it has been found that preferred polymers are ineffective in compositions comprising significant concentrations of quaternary ammonium surfactants. Similar results were found when used

Surfactants and fatty alcohol are mixed in a low speed rotor mixer while heating to 65 ° C. Stop heating and allow the mixture to cool to 65<sup>0</sup> with continued stirring. Add the cationic polymer and mix until homogeneous. The remaining components of Part A are added slowly with stirring. It is homogenized to disperse SEFA as an emulsion. It is then titrated with concentrated sulfuric acid until a pH of about 6.5 is reached. prepare a dry mixture by spreading the mixture of part A in trays and drying in a suitable (vacuum or convection) oven at a temperature not exceeding 65 ° C until substantially no water remains. The dried components of Part A are mixed with the polymeric gelling agents of Part B, heated until they dissolve or disperse. The resulting mixture is mixed with physical gelling agents. Heat and dissolve the gelling agents into the mixture. The mixture is applied to the surface or surfaces of the substrate or cooled to room temperature and stored.
