DESCRIPTION

Cleaning solution with low residue content.

5 Background of the invention

Field of the Invention

The present invention relates, in general, to a composition and a method for reducing the content of residues left by wet cleaning substrates used for cleaning hard surfaces, such as kitchens, bathrooms and other hard surfaces.

Description of the related technique

fifteen When cleaning wipes are impregnated with cleaning compositions containing cationic biocides for disinfection, normally the cleaning operation leaves a residue on the vitreous surfaces. This may be because saturated wipes leave a substantial liquid on the surface. When using a spray cleaner, waste problems are reduced since the consumer usually rubs the spray cleaner with a dry paper towel. It is the combination of saturated cleaning substrate with the cleaning composition that makes it difficult to leave a surface free of film-forming and striated phenomena.

U.S. Patents 6,936,580 and 6,716,805 to Sherry et al. disclose alkyl polyglycosides with hydrophilic polymers and propylene glycol polyether on nonwoven substrates. US Patent 4,753,844 to Jones et al. Discloses alkylpolycoside glycosides, ethanol and isopropanol on nonwoven substrates. United States Patent

US 2006/0166849 A1 discloses a cleaning composition adapted to clean a variety of hard surfaces, such that the cleaning composition includes a cationic biocide that includes biguanide and / or quaternary compounds.

US 2005/0020473 refers to a liquid cleaning composition for all purposes that is suitable for cleaning hard surfaces, comprising an aqueous composition comprising water,

35 nonionic and / or anionic surfactants, optional amphoteric surfactants and cationic compounds of a specific formula.

WO 00/05330 refers to aqueous cleaning compositions that provide disinfectant and cleaning characteristics to hard surfaces and that include one or more quaternary ammonium surfactant compounds, an organic solvent system comprising two or more glycol ethers together with a low molecular weight monohydric alcohol, one or more amine oxides, one or more alkyl polyglucoside compounds, water and optionally additional conventional additives.

EP 1 148116 refers to a hard surface cleaner, which does not require rinsing and is suitable for

Four. Five dilution that includes either a combination of specific nonionic surfactant and a quaternary ammonium compound or a combination of specific nonionic surfactant and an anionic surfactant, a water-soluble glycol ether, a binder, d-limonene and water.

Surprisingly, the present invention has discovered a liquid cleaning composition containing a quaternary biocide that when absorbed on a nonwoven substrate provides a surface disinfection with low residue content (low film formation and striatum) and low foam formation during use. . The low foaming results in low film and striatum formation and thus significantly improves consumer acceptance of the disinfectant wipe. Without pretending to be bound by any theory, the premise to achieve a low film and striatum formation is to have a cleaning composition that does not accumulate (i.e., does not have an increase in the contact angle as the composition dries) . The choice of surfactant and solvent significantly affects the properties of the formulation as it dries. Most disinfectant wipe products based on quaternary compounds leave a significant residue that is particularly noticeable on smooth vitreous surfaces. The formulation of the invention provides disinfection and cleaning of surfaces while providing low foaming and low amount of debris (i.e. film formation and striatum), thereby eliminating the need to continue with a rub step. The problems associated with the residue remaining after cleaning with wet substrates of the prior art can be avoided by means of the low residue formation compositions of the present invention. Therefore, it is an object of the present invention to provide an anti-microbial cleaning composition in a cleaning substrate that solves the disadvantages and disadvantages

65 associated with the examples of the prior art.

about 99%, or less than about 95%. Water can be tap water, soft water or deionized water. When the cleaning composition is concentrated, water may be present in the composition in a concentration of less than about 85%.

5 Substratum

The cleaning composition is part of a cleaning substrate. A variety of materials can be used as a cleaning substrate. The substrate must have sufficient wet strength, abrasion capacity, elasticity and porosity. Examples of suitable substrates include, nonwoven substrates, woven substrates, hydro-entangled substrates, foams and sponges. Any of these substrates can be water insoluble, water dispersible or water soluble.

In one embodiment, the cleaning layer of the present invention comprises a nonwoven substrate or net. The substrate is formed by nonwoven fibers or paper. The non-woven expression is defined according to the definition normally

fifteen known provided by "Nonwoven Fabrics Handbook" published by the Association of the Nonwoven Fabric Industry. A paper substrate is defined by EDANA (note 1 of ISO 9092-EN 29092) as a substrate comprising more than 50% by weight of its fibrous content formed by fibers (excluding plant fibers digested chemically) with a proportion of length with respect to diameter greater than 300, and more preferably also has a density of less than 0.040 g / cm3. Definitions of non-woven substrates and paper do not include woven textile or a garment or sponge. The substrate can be partially or completely permeable to water. The substrate can be flexible and can be resilient, which means that once the external pressure applied is removed, the substrate recovers its original form.

The methods of manufacturing nonwoven materials are well known in the art. Generally, these materials

25 Nonwovens can be manufactured by means of air deposition, water deposition, meltblown, shaping, spunbonding or carding processes in which the arc of fibers or filaments is first cut to the desired length from long strands, are passed through a stream of water or air, and subsequently deposited on a sieve through which water or air is passed on fibers. The air deposition process is described in United States patent application 2003/0036741 by Abba et al., And in United States patent application 2003/0118825 by Melius et al. The resulting layer, regardless of its method of production or composition, is subsequently applied to at least one of several types of bonding operations to anchor the individual fibers together in order to form a self-supporting substrate. In the present invention, the nonwoven substrate can be prepared by a variety of processes including, but not limited to, air interlacing, hydro-interlacing, thermal bonding and combinations of these processes.

35 Additionally, the first layer and the second layer can be joined, as well as additional layers, when present, to one another in order to maintain the integrity of the article. The layers can be joined by means of hot spots or using the heat generated by ultrasound waves. The joint can be configured so that geometric shapes and patterns, for example, diamonds, circles, squares, etc., are created on the outer surfaces of the layers and the resulting article.

The cleaning substrates can be provided with a dry, pre-moistened or impregnated cleaning composition, but dry to the touch. In one aspect, dry cleaning substrates can be provided with dry or substantially dry cleaning or disinfecting agents or cleaners, applied as a coating or in a layer of multi-lobular and multi-component fiber. In addition, the cleaning substrates can be provided in a pre-moistened and / or saturated form. The cleaning substrates can be kept moist over time in a container suitable for sealing such as, for example, in a bucket with a lid that joins, plastic bags suitable for sealing, containers, jars, buckets and the like. Desirably, the stacked and wet cleaning substrates are kept in a container suitable for re-sealing. The use of the container suitable for resealing is particularly desirable when volatile liquid compositions are used, since evaporation of substantial amounts of liquid can occur when the first substrates are used, leaving the rest of the substrates with little or no amount of liquid . Exemplary re-sealing containers and dispensers include, but are not limited to, those described in U.S. Patent No. 4,171,047 to Doyle et al., U.S. Patent No. 4,353,480 to McFadyen, the patent No. 4,778,048 of Kaspar et al., the patent

55 U.S. Patent No. 4,741,944 to Jackson et al., and U.S. Patent 5,595,786 to McBride et al. The cleaning substrates can be incorporated or oriented in the container as desired and / or can be folded as desired in order to improve the ease of removal or use as is known in the art. The cleaning substrates of the present invention can be provided in the form of a case, in which a plurality of cleaning substrates and cleaning utensils are provided in an individual package.

The substrate may include both natural and synthetic fibers. The substrate may also include water soluble fibers or fibers suitable for dispersion in water, from the polymers described herein. The substrate may be formed of fibers of appropriate natural and / or unmodified natural origin including cotton, strands of esparto, bagasse, hemp, linen, silk, wool, wood pulp, chemically modified wood pulp, 65 jute, ethyl cellulose and / or cellulose acetate. Various pulp fibers may be used including, but not limited to, thermomechanical pulp fibers, chemo-thermomechanical pulp fibers, chemo-mechanical pulp fibers, fiber fibers.

E07865649

mechanical pulp of refining device, pulp fibers of stone residues, peroxide mechanical pulp fibers and the like. Suitable synthetic fibers may comprise fibers of one, or more, of polyvinyl chloride, polyvinyl fluoride, polytetrafluoroethylene, polyvinylidene chloride, polyacrylics such as ORLON®, polyvinyl acetate,

5 Rayon®, poly (ethyl vinyl acetate), soluble or non-soluble polyvinyl alcohol, polyolefins such as polyethylene (for example PULPEX®) and polypropylene, polyamides such as nylon, polyesters such as DACRON® or KODEL®, polyurethanes, polystyrene and similar, including fibers comprising polymers containing more than one monomer.

The cleaning substrate of the present invention may be a multi-layer laminate and may be formed by several different techniques including, but not limited to, the use of adhesives, needle piercing, ultrasonic bonding, thermal calendering and through air bonding. . Said multi-layer laminate may be an embodiment in which some of the layers are spunbond and some are meltblown, such as a spunbond / meltblown / spunbond (SMS) laminate as disclosed. in U.S. Patent No.

fifteen 4,041,203 of Brock et al. and in U.S. Patent No. 5,169,706 to Collier et al. The SMS laminate can be prepared by means of sequential deposition on a conveyor belt that moves or a spunbond network layer can be formed first, then a meltblown network layer and finally another layer bonded by spun and then bond the laminate in the manner described above. Alternatively, the three network layers can be formed individually, can be collected in rolls and can be combined in a separate joining stage.

The substrate may also contain super absorbent materials. Those skilled in the art know a wide variety of highly absorbent materials (also known as super-absorbent materials). See, for example, U.S. Patent No. 4,076,663 issued February 28, 1978 to Masuda et al., U.S. Patent No. 4,286,082 issued August 25, 1981 to Tsubakimoto et al., United States Patent No. 4,062,817 issued December 13, 1977 to Westerman and United States Patent No. 4,340,706 issued July 20, 1982 to Obayashi et al. Generally, the absorbent capacity of such highly absorbent materials is many times greater than the absorbent capacity of the fibrous materials. For example, a fibrous matrix of wood pulp fluff can absorb approximately 7-9 grams of liquid (such as 0.9% by weight saline solution) per gram of wood pulp fluff, while highly absorbent materials they can absorb at least about 15, preferably at least about 20, and often at least about 25 grams of liquid, such as 0.9% percent saline, per gram of highly absorbent material. US Patent No. 5,601,542, issued to Melius et al., Discloses an absorbent article in which the super-absorbent material is

35 present in layers of discrete bags. Alternatively, the super-absorbent material may be within a layer or dispersed throughout the substrate.

55 Wiper Supply System

Suitable wipe supplier systems include both individually packaged disinfectant wipes and one or more disinfectant wipes packaged together or other appropriate disinfectant items. The delivery system suitably comprises a container suitable for sealing, which is substantially impermeable against liquids and / or gases. The term "container" refers, but is not limited to, packages containing one or more individual wipes and mass delivery devices, such as containers, buckets and jars, which supply one disinfectant wipe each time, and also an appropriate means with additional features to re-seal the mass delivery device between each use in order to preserve the integrity of the disinfectant items. An example is a cylindrical container supply device that houses a roll of individual wipes, separated by means of perforations to allow tearing of the individual wipes

E07865649

22-08-2014

for use Said delivery device is properly held by the user and is grasped while the wipe is removed. Appropriate delivery devices have a resealable supply cap and a hole (See, for example, Chong, US 6,554,156 common assignment and incorporated herein by reference) which supplies individual wipes to starting from a roll and that

5 it retains the next wipe in a position ready for the next supply, allowing the sealing of the supply lid in order to close the container with respect to the environment when it is not in use. A further example, within the scope of the present invention, consists in packaging the individual wipes in an unbound manner, in a delivery device that allows their removal one at a time, as in the case of the wipe / delivery device combinations known in the art.

10 Wipes supply devices are convenient objects that provide moistened sheets or wipes for a variety of uses. Normally, the wipes are formulated for specific purposes including wipes for children, wipes for personal hygiene, wipes for cleaning dishes, wipes for the treatment of hard surfaces, disinfectant wipes, cosmetic or sanitary wipes, hand wipes, wipes used in the

fifteen car cleaning, or for the maintenance and domestic or institutional cleaning, cleaning and maintenance of computers and other areas in which a substrate having a useful liquid treatment composition has application.

Instructions for use

twenty In one embodiment, the instructions include rubbing the clean surface with the wipe and letting it air dry. In one embodiment, the instructions include rubbing the surface, using enough wipes so that the treated surface is visibly wet for 30 seconds or 1 minute or 2 minutes or 4 minutes, and letting the surface dry. For heavily soiled surfaces, it may be necessary to clean excess dirt first. In a

25 embodiment, the instructions include rubbing the surface to be disinfected with a wet cleaning wipe and letting the surface dry.

Examples

30 In Table I, the formulas on wipe substrates with a loading ratio of 3.75 were introduced. Subsequently, the wipe substrates were rubbed on glass mirrors and allowed to dry. The test on black enamel and ceramic tile surfaces was carried out. The examples show the results on mirrors, which were examined visually for film and striatum formation, and were classified from very low film / striatum formation to low and medium and high. C18-C10 alqulipoliglucoside is superior to the oxide of

35 amine.
