TECHNICAL FIELD

The present description generally refers to conformable articles.

BACKGROUND

Cleaning is an activity that has been done for many years. Over time, cleaning has included the use of compositions such as bar and liquid soaps, liquid body soaps, shampoos, conditioners, liquid and / or solid detergents, and the like. In these compositions, consumers desire good cleaning properties and foaming characteristics, softness for cleaning the surface being treated, such as leather, cloth, or hard surface, and the ability to provide beneficial agents to the surface being treated.

To enhance the consumer experience, these cleaning compositions can also be combined with implements, such as a washcloth, sponge, or bean bag. For example, many consumers dose liquid soaps or liquid body washes on a bean bag, and then clean themselves by applying the pad to their skin and / or hair. Similarly, many consumers scrub bar soaps with a washcloth, and then clean themselves by applying the washcloth to their skin and / or hair. Additionally, many consumers apply cleaning compositions to sponges to clean hard surfaces.

Although the experience of a consumer with a composition of

<img file="MX355304B_D0008.tif" />

ΙΜΡΪ

INSTITUTE ΜΓΧίςΑΝκ)

Dfc LA PRO, Λ '^{, Λ}^ cleaning can be improved by combining the cleaning composition with W ^ tti'pleme to date, this experience has not been entirely ideal. --RoF - exemplaryComposing these cleaning compositions with one implement tends to clutter up the kitchen, shower or bathroom, because the consumer needs to transport or store bulky bottles, bars, pots and / or tubes of cleaning products and implements for these. Additionally, the combination requires the user to perform additional steps to apply the liquid body soap or soap onto the implement, and then rub or wipe the implement onto the surface being treated rather than applying the liquid soap to the body and / or soap directly. As such, it tends to consume more water, which increases waste and the environmental impact produced by the consumer.

Furthermore, it may be difficult for certain personal hygiene compositions, such as bar soaps, to provide the consumer with the desired depot of beneficial agents, even when combined with an implement. Some attempts have been made to combine an implement with a personal hygiene composition into a personal care item. However, these executions did not turn out to be ideal. For example, such an item included a rigid bar soap along with an implement. The rigidity of this type of execution does not conform to the surface to which it is applied, which makes it difficult to thoroughly clean the surface being treated.

Accordingly, it would be desirable to provide a conformable cleaning article that has a cleaning composition that can have desirable cleaning properties including suitable foaming and rinsing characteristics.

"Non-woven fabric" refers to a substrate that comprises fibers that are not woven into a fabric, but rather are formed into a canvas. The fibers can be random (i.e., randomly aligned) or the fibers can be non-random. For example, the non-woven fabric may be carded (i.e., combed to orient primarily in one direction).

"Personal care" refers to a composition or article for topical application to the skin and / or hair. The personal care compositions can be rinse-off formulations, in which the composition can be applied topically to the skin and / or hair and then rinsed within a few seconds or minutes of application. Furthermore, the composition could be removed by rubbing by using a substrate.

"Personal care item" refers to an item that may include a personal care composition and a water permeable substrate. The personal care article may be reusable and conform to the object, such as a body, to which the article is applied.

"Water insoluble substrate" refers to a substrate that does not dissolve in water during the life of the article.

"Water permeable substrate" refers to a substrate that provides enough water to penetrate the personal care article to provide desired foaming capabilities.

II. Articles

Compositions, like the cleaning composition, can come in many forms. A shape is a solid composition, like a bar. Bar cleaners, such as bar soaps, can generally be non-conformable and rigid. The stiffness of most bar cleaners can cause them to be difficult to grip, making it more difficult to use during cleaning. Bar cleaners can also have the disadvantage that only the surface that comes into contact

IMPI

INSTíTi Τ 1 Xtf \ N'O · Α0 directly with the surface being treated can be used for cleaning, and this surface may be limited by the unmouldable nature ~ bafr «-.-- B-ji conventional rigid bar may have a molding value of approximately 2.5 kg / mm or greater.

Insoluble components in stick compositions can contribute to stick stiffness. With the use of conformable or conformable articles and / or compositions, the need for rigidity can be dispensed with and, frequently, may result in removal of the insoluble components giving a faster dissolving composition. While it is desirable to have a composition that provides adequate cleaning properties during a cleaning event (i.e., dissolves well enough to release surfactant), there must be a balance between these cleaning properties and the life of the composition. Otherwise, the composition may be completely consumed in just one or a few events, and the composition may be too costly and polluting for the environment.

The speed with which a consumer exhausts a composition or an article can be measured by the consumption index, the method of which is described below. Substrates can be used to control the rate of consumption. Thus, when the compositions dissolve rapidly, substrates can be used to increase the rate of consumption to a desirable level, such as that of a typical bar soap. In certain examples, a substrate can act as a water flow limiting substrate to effectively increase the rate of consumption. In certain examples, the water flow of the substrate can be manipulated by the chemical or physical texture of the substrate. For example, the substrate may contain pores to allow more water to pass through. If less water is desired to pass, the number of pores may be reduced during substrate manufacture or some pores may be sealed.

An item can be conformable. A conformal article has a conformation of approximately 5 or greater in at least one uTiáCcííreccIoñ óoMo áó^_measured by the cantilever fit test to be described below. A conformable article can have a conformation value of about 10 or greater, of about 30 or greater, of about 50 to about 90, or any combination thereof, in at least one direction as measured by the cantilever fit test.

An article can include a substrate and a composition. The article may further comprise multiple substrates and / or multiple compositions. The item can be reusable.

The article may be a personal care article comprising a personal care composition. The personal care article can be used, for example, for skin cleansing, hair cleansing, deposition of a beneficial agent and / or active ingredient, shaving preparations, after-shave treatment, pet care, or a combination of these. In one example, the personal care article is a personal hygiene article.

A composition can have mouldable or unmouldable characteristics. For example, if the composition is a conformable personal cleansing composition for skin cleansing, then the composition will flex to some degree to better contact a curved portion of the body, such as an arm. Therefore, if the moldable personal care composition is originally flat and curved, when applied to an arm for cleaning, it will have a certain amount of flex to better conform to the arm. Similarly, if the shape of the composition has a slight bend, when applied to the arm, the composition will flex to a certain degree to more fully contact the arm. For him

On the contrary, if the personal care composition is curved in such a way that it does not need to flex to adapt to a curved surface, com ^ -eLbi ^ za_r-entonGSS.s &amp; .- ··· 'will flex to straighten when applied to a less curved surface, such as the abdomen.

In certain examples, the molding of a composition can be measured in accordance with the molding test described in more detail below. In certain examples, a composition may comprise a molding value of about 1.50 kg / mm or less. In certain examples, the molding value of the composition may be approximately 1.35 kg / mm or less; approximately 1.25 kg / mm or less; about 1.2 kg / mm or less; about 1.1 kg / mm or less; or about 1.0 kg / mm or less. In additional examples, the composition may have a molding from about 0.01 kg / mm to about 1.50 kg / mm; from about 0.03 kg / mm to about 1.50 kg / mm; from about 0.05 kg / mm to about 1.25 kg / mm; from about 0.05 kg / mm to about 1.15 kg / mm; and / or about 0.10 kg / mm to about 1.1 kg / mm.

In some examples, the article and / or composition may become moldable after exposure to water. Therefore, you can have a non-compliant composition or article that, after being exposed to a liquid, such as water, during an event of use, becomes compliant. If an item or composition becomes moldable at the end of a second use event, then it is considered moldable.

An unmouldable composition has a molding value of 2.0 kg / mm or greater. Unmouldable compositions require more than an average force used during cleaning to follow the line of the surface to which they are applied.

<img file="MX355304B_D0014.tif" />

whether or not it will change shape at all. The non-compliant compositions pufflBsff also have a molding value of about -z? R5-kg / mm or greater.

An item can have a consumption index. The consumption index is a measure of the amount of composition used during a usage event. A method of measuring the item's consumption rate is described in detail below.

An item can have a consumption rate of about 20g / use or less. Additionally, an item may have a consumption rate of approximately 15 g / use or less; from about 1.5 g / use to about 15 g / use; from about 2.5 g / use to about 10 g / use; and / or approximately

3.5g / use to about 6.5g / use.

A cleaning article may comprise a cleaning composition and a first water permeable substrate. A cleaning article 10 in accordance with an example is shown in Figures 1 to 3, respectively. As illustrated more clearly in Figure 3, the cleaning article 10 may include a first cleaning composition 14 and a second cleaning composition 15. The cleaning compositions may be compliant, non-compliant, or a combination of these. The first water-permeable substrate 22 may be adjacent to the first cleaning composition 14, and a second water-permeable substrate 24 may be adjacent to the second cleaning composition 15 as further shown in Figure 3. A barrier 13 it defines a first zone 30 and a second zone 32 such that the first cleaning composition 14 is placed practically in the first zone 30 and the second cleaning composition 15 is placed practically in the second zone 32. In an example depicted in Figure 3, a seal 16 joining the first and second water-permeable substrates (22, 24) is visible only at ends 18, but may surround the first and second cleaning compositions (14, 15) .

While the modalities are described below, for the sake of brevity, with respect to cleaning and / or personal care articles, it is envisioned that the combinations described can be used with any article as described in the present disclosure. An example of a suitable item is a cleaning item. A cleaning article may comprise a first and second compositions, which may be in the first and second zones and a first water permeable substrate. The first and second compositions may be cleansing compositions, charitable compositions, or combinations thereof. The first and second zones can be defined by one or more barriers. The first composition can be the same or different from the second composition. However, a cleaning article can comprise two or more compositions, where each of the care compositions can be in two or more areas. In certain examples, the cleaning article may further comprise a third composition in a third zone, wherein each of the first, second, and third zones is defined by one or more barriers, and wherein the first substrate permeable to the Water is adjacent to the first, second, and third compositions.

An article may further comprise additional compositions and / or zones. For example, a fourth composition may be in a fourth zone, where each of the first, second, third, and fourth zones is defined by one or more barriers, and where the first water-permeable substrate is adjacent to the first, second, third, and fourth compositions. In other examples, an article may

Each of the compositions can be configured to release in the respective zones.

Another example of an item is a personal care item. A personal care article may comprise a personal care composition. A personal care composition may be a rinse-off composition (eg, a cleanser) or a non-rinse and apply composition (eg, a humectant). A personal care composition can comprise a cleaning phase, a beneficial phase, or a combination of these. The personal care composition can comprise one or more beneficial agents that can be deposited on the skin and / or hair of an individual. The personal care compositions can be compliant or non-compliant.

The cleaning phase and the beneficial phase can be included in one or more areas such that the deposition of a beneficial agent can occur during the cleaning. In an example having a first zone and a second zone, one of the first zone and the second zone may be a cleaning phase and a charitable phase, wherein the cleaning phase and the charitable phase may be mixed. In another example, one of the first zone and the second zone may be a cleaning phase and a charitable phase, wherein the cleaning phase and the charitable phase may have a pattern.

In some examples, deposition of a beneficial agent may occur after cleaning. For example, in an article having a first zone and a second zone, one of the first zone and the second zone may be a cleaning phase and a charitable phase or a first zone may have a composition of

In another example, as illustrated in Figure 4, a personal care article 110 may include a first personal care composition 114 and a second personal care composition 115. A first water permeable substrate 122 may be adjacent to the first personal care composition 114, 10 while a second water permeable substrate 124 may be adjacent to the second personal care composition 115. And, similar to the article shown in Figure 3, a barrier 113 can define a first zone 130 and a second zone 132 so that the first moldable personal care composition 114 is placed in the first zone 130 and the second composition for personal care 115 15 is placed in the second zone 132.

As illustrated in Figure 4, a seal 116 joining the first and second water-permeable substrates (122, 124) may be visible only at ends 18, but may surround the first and second personal care compositions (114 , 115). Additionally, a first water-insoluble substrate 126 may be adjacent to the first water-permeable substrate 122 and a second water-insoluble substrate 128 may be adjacent to the second water-permeable substrate 124. The first and second water-insoluble substrates (126, 128) may be formed of the same or different materials. Similar to the seal of the first and second water-permeable substrates (122, 124), although only visible at ends 118, the seal 116 of the first and second water-insoluble substrates (126, 128) can surround the first and second compositions for personal care

INSTITUTO MtXICANú (114, 115). The seal 116 of the first and second substrates (126, 128) is insoluble, however, it may be sealed in other configurations, or it may be, for example, a bag. While the description in Figure 4 is specific to a personal care item, the description is similarly applicable to other items, as described in the present description.

The article may further comprise a chamber 40, 140, as seen, for example, in Figures 3 to 4. In certain examples, a chamber may be an open space between a substrate and a composition or between a substrate and another substrate, wherein the substrate is not in contact with the composition or the other substrate. The substrate (s) may be flexible so that they are in contact with the composition (or other substrate) in some areas and not in others. The places where the substrate may or may not be in contact with the composition or other substrate may move when the substrate (s) and composition change during handling and / or use.

As mentioned above, articles can have a variety of settings. In a configuration, an item can include a top side and a bottom side. As in the examples shown in Figures 3 to 4, a first zone can be on an upper side of the article and a second zone can be on a lower side of the article. However, in other examples, the first zone may be on the bottom side and the second zone may be on the top side.

Furthermore, the article may have a configuration that includes having a right side and a left side, and the first zone can be placed on either one of the right side or the left side and the second zone can be placed on the remaining side. In one example, as shown in Figures 5A, 5B, and 5C, a first zone 230 is shown placed on a left side and a second zone 232 is placed on a right side, where the first zone 230 and the second zone 232 are defined by a barrier 213. In said example, both the first zone 230 and the second zone are placed.

to be in contact simultaneously with the surface being treated after the application of article 210. Additionally, barrier 213 can act as a hinge and then the article can be conformable.

In another example, and as shown in Figures 6A, 6B, and 6C, the first and second zones 330, 332 may take different shapes than those shown in Figures 5A, 5B, and 5C, but an article 310 may still adopt a configuration similar to that shown in Figures 5A, 5B, and 5C, such that a first zone 330 is shown placed on a Left side and a second zone 332 is placed on a right side, the first zone 330 and the second zone 332 are defined by a barrier 313, and both the first zone 330 and the second zone 332 can be positioned to be in contact simultaneously with the surface being treated after the application of article 310. In certain Examples, one of the top side and the bottom side can be a cleaning composition with a beneficial phase. Similarly, in other examples, one on the right side and the left side may be a cleaning composition with a beneficial phase.

Another illustrative article is shown in Figures 7 to 8. Article 410 may include a first composition 414 in a first zone 430 and a second composition 415 in a second zone 432. A first water permeable substrate 422 may be adjacent to the first Composition 414 in the first zone 430, while a second water permeable substrate 424 may be adjacent to the second composition 415 in the second zone 432. The first and second compositions 414, 415 can be separated by a first interior substrate 434, a second interior substrate 436, and / or a first barrier 438. Particularly, the first Interior substrate 434 can be placed between the first barrier 438 and the first zone 430 and the second interior substrate 436 can be placed between

Additionally, a first substrate that is insoluble to water-4 ^ üqptJHdg^{,, J}gsTar ~ adjacent to the first water permeable substrate 422 and a second water insoluble substrate 428 may be adjacent to the second water permeable substrate 424. The first and second water insoluble substrates (426, 428) may be formed of the same or different material. As described herein, a chamber 440 may be a space between a substrate and a composition or between a substrate and another substrate, where the substrate is not in contact with the composition or the other substrate.

A first barrier may be, for example, a bundled substrate, non-woven fabric (i.e., a natural or synthetic non-woven fabric that includes fibrous and non-fibrous non-woven fabrics), a fabric, a film (eg, a film formed), a sponge (p. eg, a natural and / or synthetic sponge), a crosslinked polymeric mesh (ie, a "gauze"), a wadding, spunbond, spunlace, waterjet bonded, carding, punching, or any other suitable material as Described below in greater detail, so that the first barrier can act as a spring or pump to facilitate agitation of the personal care article and increase foam production. A first barrier can avoid interfering with the sealing of the first and second water-permeable substrates and / or the first and second water-insoluble substrates so that a seal can exclude the first barrier.

The article may Include from about 0.5% to about 25,000%, by weight of a total substrate (s), of full composition, which may be a combination of all compositions (eg, first care composition personal, second composition for personal care, etc.) in an article. The total substrate can be a combination of all substrates in one article. For example, an article may Include more than approximately 3,500%, by weight of the total substrate (s);

<img file="MX355304B_D0019.tif" />

more than about 4000%, by weight of the about 4250%, by weight of the total substrate (s); more about. 4500%, by weight of the total substrate (s); more than about 4750%, by weight of the total substrate (s); more than about 5000%, by weight of the total substrate (s), of a total composition; or any combination of these.

Items can be any suitable shape, for example, oval, square, rectangular, circular, triangular, hourglass-shaped, hexagonal, C-shaped, etc. Shapes include any suitable shape that facilitates consumer use, for example, mitts, gloves, arm / hand bands.

Without wishing to be bound by theory, and as described above, it is believed that an article, for example, a personal care article, can eliminate the problems associated with reuse, waste, consumption, foam, dissolution, and conformity or molding. As described in the present disclosure, it was found that the use of a personal care composition can improve the durability of a personal care article so that the personal care article can be used for a number of use events and it can be shaped to or mimic a shape of the surface to which the personal care composition is applied. Additionally, it was found that such a personal care composition can be combined with a water insoluble substrate made of particular materials to control the flow of water and thus the dissolution and consumption of the personal care composition to increase the Durability of the personal care item without sacrificing foam or other desirable properties for consumers.

Without wishing to be bound by theory, it is believed that providing a multi-zone personal care article can eliminate the problems associated with efficiency, ergonomics, and waste. An article for personal care

By including multiple zones in a single personal care item, stages involving multiple containers and / or items can be eliminated and consumers can take advantage of the ease of use of a single personal care item to obtain beneficial properties. and cleaning desired.

Methods of increasing foam properties may include providing a personal care article that has two or more zones defined by one or more barriers. The foam can be produced into a personal care article containing the personal care compositions by manual agitation of the personal care article. However, by increasing aeration in the personal care article, the foam produced by such agitation can be improved. Without wishing to be bound by theory, it is believed that by providing one or more barriers between the zones, additional oxygen can be introduced to the personal care compositions during agitation to increase the foam that is produced, and thus, the article For personal care it can be used more efficiently and effectively.

A._Substrates

An article can comprise at least one substrate. The substrate can enhance the cleaning and therapeutic treatment of a treated surface, such as skin, hard surfaces, and / or hair. For example, when physically coming into contact with the

INáTITVTC ¢, -—- // ¡- / - A surface that is treated like skin and / or hair, the substrate can remove dirt, makeup, dead skin and other debris, so that the substrate— can act As an effective foaming and / or exfoliating implement, but it can also be non-abrasive to the skin. A substrate can be a composite (that is, the substrate has multiple sheets that can be of the same or different materials). In one example, the substrate can be insoluble in water. In other examples, the substrate may be water permeable. However, the article may comprise both water permeable substrates and water insoluble substrates.

A substrate can at least partially surround one or more 10 compositions. Additionally, a substrate can completely surround one or more personal care compositions. A substrate can be in the form of a bag, pocket, wrap, or any other suitable configuration to hold one or more compositions.

As described above, the substrate can be water permeable.

When permeable to water, the substrate can have a water flow index. The water flow index can be used to limit the wetting of the composition included in the article and, thus, control the foam, dissolution and / or consumption of the composition included in the article. Without being limited by theory, the first substrate can handle or limit the flow rate of water to provide controlled wetting and extend the life of a composition while still allowing sufficient wetting to provide, for example, a suitable foam. In certain examples, the flow rate of the water may be approximately 0.1 cm³/ cm²/ s at about 200 cm³/ cm²/ s, about 0.4 cm³/ cm²/ s at about 120 cm³/ cm²/ s, about 20 cm³/ cm²/ s at about 100 cm³/ cm²/ s, or any combination of these, as measured by the water flow index test

<img file="MX355304B_D0021.tif" />

described below. The ability to control the rate of water flow can allow adjustments so that the composition, such as a cleaning composition, can be reusable and therefore last through various shower, bath or toilet experiences, at at the same time that it presents the foaming characteristics that consumers expect.

In certain examples, there may be a water flow differential between the substrates. In certain examples, the flux differential between substrates can be at least about 2.5 cm³/ cm²/ s; about 3.0 cm³/ cm²/ s or more; or about 4.0 cm³/ cm²/ s or more.

In certain examples, the substrate can be a non-woven fabric (i.e., a natural or synthetic non-woven fabric that includes fibrous and non-fibrous non-woven fabrics), which can typically have flat part regions (i.e., regions that do not allow water and / or personal care composition to pass through) and openings; a tissue; a movie (eg, a formed movie); a sponge, which may include a natural and / or synthetic sponge (eg. eg, polymeric mesh sponge), examples of which may include those described in European patent application no. EP 702550A1 published March 27, 1996; a crosslinked polymeric mesh (ie, a "gauze"), examples of which may include those described in US Pat. USA no. 4,636,419; a wadding spunbond; spunlace; cohesive by jet of water; carded; punching; or any other suitable material. In certain examples, the substrate may be a composite material which may include, for example, one or more sheets of the same or different materials, such as overlapping nonwovens, woven fabrics, films, sponges, gauze, wadding, and the like. Physically bonded together continuously (eg, laminated, etc.) in a discontinuous pattern or by bonding to the outer edges (or periphery) of the substrate and / or at different locations. Suitable examples for each type of substrate and other suitable substrate materials are described in US Provisional Application. USA with no. of series 61 / 523,824 and the application of the EE.

Parameters to consider when selecting substrates (eg, formed films) may include thickness, configuration, polymer stiffness, and permeability. Additional information on these parameters is further described in the US provisional application. USA with no. of series 61 / 523,824 and the application of the EE. USA with no. serial 13 / 438,918.

A substrate can include one or more openings so that water, composition, and / or foam, for example, can pass through the substrate. In one example, where a permeable substrate can be adjacent to the composition, water can pass through the water permeable substrate to interact with the composition. As the composition dissolves, it can then pass through the substrate to supply a treated surface (eg, skin).

In one example, the permeability of the openings can be selected based on a half-life of dissolution of a composition and a desired reusability of the article. For example, when the dissolution half-life of the composition is high, a higher level of permeability can be selected to offset the high dissolution half-life and provide a desirable consumption rate for the article. Alternatively, when the dissolution half-life of the composition is low, the permeability of one or more of the openings may be less and still provide a desirable consumption rate for the article. In certain examples, a substrate can include a permeability of about 1 aperture / cm² or greater, about 10 openings / cm² or greater, about 100 openings / cm² or greater, approximately 500 openings / cm² or older,

The openings may or may not have perforations, or a combination thereof For example, one or more of the openings may include well-defined perforations, such as microperforations or macroperforations, holes, perforations, cavities, fibrous and / or non-fibrous screeds elevated or depressed , gaps between regions, and the like, which can allow, for example, water and / or composition to pass through the substrate.

A substrate can be a contact substrate, which can be a substrate for contacting a treated surface (eg, skin). A substrate may further be a contactless substrate. Non-contact substrates can be used, for example, to help impart the desired properties of index consumption, softness, foam, etc. to an article.

In certain examples, a substrate may require sufficient tensile strength to effectively perform a desired function. For example, a contact substrate may require greater tensile strength than a non-contact substrate, because the contact substrate may be in contact with a treated surface. In one example, a substrate can provide ultimate tensile strength of about 10 g / mm (width) or greater, about 30 g / mm (width) or greater, approximately 60 g / mm (width) or greater, or approximately 200 g / mm (width) or greater and a stiffness of approximately 1 g / mm (width) or greater, approximately 2 g / mm (width) or greater, approximately 7 g / mm (width) or greater, approximately 20 g / mm (width) or greater, or approximately 80 g / mm (width) or greater, measured by the voltage test described below.

The substrate can further provide a variety of textures. Textured substrates can be used for contact substrates and substrates without

For example, the item may include a grip side, and ... a, Jad &amp;&gt;. JJ, e. ^ Substrate application. In one example, the grip side may include a texture that is the same as that of the substrate application side. In another example, the gripping side may include a texture that is different from that of the substrate application side.

An article can comprise more than one substrate. More than one substrate can be contact substrates. A combination of contact substrates can be used, for example, to give different properties to different sides of an article.

In one example, a first water-insoluble substrate may be a contact substrate that facilitates grip, and a second water-insoluble substrate may be a contact substrate in another part of the article selected for its application properties. In one example, a personal care item can have an exfoliating contact substrate on one side of the personal care item and a relaxing contact substrate on the other side.

An article can include more than one substrate, where a substrate can

Including a contact substrate and another substrate can include a contactless substrate. For example, the first and second water-insoluble substrates may be contact substrates, while the first and second water-permeable substrates may be non-contact substrates. A non-contact substrate can be surrounded, at least partially, by at least one contact substrate. Two contactless substrates can be surrounded by two contact substrates. Furthermore, an article may comprise a first side and a second side, such that the first water permeable substrate may be adjacent to a first composition on one side of the article, a second water permeable substrate may be adjacent to a second composition on On the other side of the article, a first water-insoluble substrate may be adjacent to the

As described above, one or more barriers can define two or more zones of an article. In certain examples, such as the example shown in

Figure 8, an article may include a first zone and a second zone separated by a first Interior substrate, a second interior substrate, and a first barrier, such that the first Interior substrate can be placed between the first barrier and the first zone and the second interior substrate can be placed between the first barrier and the second zone. A barrier can be a substrate, and as such the barrier can be any of the substrates described in the present description. In one example, the barrier may be a formed film, a polyurethane sponge, gauze, a seal, a substrate, or combinations of these. In certain examples, the barrier can act as a spring or pump to facilitate agitation of the article and increase foam production. In such examples, the barrier may comprise a grouped substrate. In certain examples, one or more barriers may be practically impervious, while in other examples, the barrier may be practically permeable (eg, where the first and second zones comprise a cleaning composition).

A combination of substrates can be used not only to provide different properties as a user experience, as an exfoliant compared to a relaxer, but the combination of the substrates can also be used to provide other desirable properties of an article, such as rate of consumption and suitable foaming properties. When combining substrates to form an article, the properties of the composition, in addition to the individual properties of the substrates, must be taken into account to obtain the article with the desired properties. In a

In certain examples, the two non-contact substrates can be the same. In certain examples, the two contact substrates can be the same. In addition, and as described in the present disclosure, to provide a desirable consumption rate for an article, a substrate with a higher level of permeability can be selected to counteract a care composition with a high dissolution half-life and A substrate with a lower permeability level can be selected to counteract a care composition with a lower half-life of dissolution. Therefore, in certain examples, different substrates can be selected for each zone so that the different zones can have similar consumption rates and the article as a whole can be consumed at an effective rate.

B._Compositions for personal care

A personal care item may comprise a substrate and composition (s) for personal care. Such personal care compositions can be rinse-off compositions (eg, a cleanser) or non-rinse and apply compositions (eg, a humectant). Furthermore, the compositions can be compliant, non-compliant, or a combination of these. A personal care composition can be in any suitable shape, for example, powder, ball, bar, square, rectangle, octagon, circle, cube, sphere, etc. An example of a conformable personal care article 510, where the personal care compositions are in the form of bars can be seen in Figure 9.

As described above, a personal care item may comprise first and second personal care compositions, the

which can be in the first and second zones, and a first water permeable substrate. The first and second zones can be defined by one or more barriers. In certain examples, the first personal care composition may be the same as the second personal care composition. However, a personal care article may comprise two or more personal care compositions, wherein each of the personal care compositions may be in two or more areas. A personal care article may further comprise a third composition for personal care in a third zone, where each of the first, second, and third zones is defined by one or more barriers, and wherein the first substrate Water permeable is adjacent to the first, second, and third personal care compositions. The personal care article may further comprise additional compositions and areas. Each of the personal care compositions can be configured to release in the respective areas.

As described herein, a personal care composition may be a rinse-off composition (eg, a cleanser) or a non-rinse and apply composition (eg, a humectant). In certain examples, a personal care composition can comprise a cleaning phase, and in certain examples, the personal care composition can comprise a beneficial phase. In certain examples, a personal care composition can comprise a cleaning phase and a beneficial phase, wherein the cleaning phase can be a continuous phase domain. The personal care composition may further comprise one or more beneficial agents that can be deposited on the skin and / or hair of an individual. The cleaning phase and the beneficial phase can be included in one or more areas such that the deposition of a beneficial agent can occur during the cleaning. In

The deposition of a beneficial agent can occur after cleaning. In an illustrative article having a first zone and a second zone, one of the first zone and the second zone may be a cleaning phase and a charitable phase or zone one may comprise a cleaning phase and zone two may comprise a beneficial phase, where the beneficial phase can be used after cleansing to apply a beneficial agent to an individual's skin. Such an arrangement may allow an individual to cleanse the skin and / or hair before applying the beneficial agent through the area having the cleansing phase and / or the beneficial phase.

In certain examples, a personal care composition can have a half-life of dissolution. In certain examples, a personal care composition can have a half-life of dissolution of about 1.0 min to about 15 min; from about 1.1 min to about 13 min; from about 1.2 min to about 12 min; from about 1.3 mln to about 11 mln; from about 1.4 min to about 8.0 min; from about 1.5 min to about 5 min; or any combination of these, as measured by the dissolution rate test described below.

A personal care composition can be adjacent to one or more substrates. For example, a personal care article may include a personal care composition arranged between one or more of the substrates. By

IV. Methods of use

A method of cleaning the skin and / or hair with a personal hygiene article may include moistening a reusable personal hygiene article and contacting the skin or hair with the moistened personal hygiene article.

A personal care item may be intended to be moistened with water before use. The personal care item can

- moisten, for example, by immersion in water or by placing the personal care article under a stream of water. In one example, foam can be generated in the personal care article by agitating and / or mechanically deforming the personal care article either before or during contact of the article with the skin and / or hair. The generated foam can be useful to clean the skin and / or hair. During a cleaning process and subsequent rinsing with water, any therapeutic or aesthetic benefit agent can be deposited on the skin and / or hair.

INDUSTRIAL the first composition for personal care can be the same as the second composition for personal care. Furthermore, the first and second zones can be defined by one or more barriers. The method of increasing lather may further include stirring the personal care article. In one example, such agitation may include compressing the personal care article repeatedly vertically so that constant flattening and reformation of one or more barriers achieves increased foam production. In certain examples, each of the first and second personal care compositions can be placed practically on the outer portions of the personal care article, relative to one or more barriers, so that the personal care compositions can enter more easily contact with skin and / or hair and water to allow dissolution. In certain examples, a personal care item can produce approximately 200 ml or more of foam in accordance with the piston foam test described in this description. Foam measurements are shown below in Table 1.

As described above, the present description describes personal care articles used in said method of increasing foam. As such, the personal care compositions used with the personal care article may include those described above. Similarly, the substrates and barriers used for the personal care article may also include those described above. For example, the barrier may be any of a formed film, a polyurethane sponge, gauze, a seal, a substrate, and combinations of these. In one example, a barrier can comprise a grouped substrate. The barrier can act as a spring or pump to facilitate agitation of the personal care item and increase foam production.

V. Procedures

A._Water flow index test

The water flow index test can measure the water permeability of a substrate. Without intending to be bound by theory, water permeability may be a major determinant of surfactant life in a foaming substrate that is used in the presence of water, especially running water. When a surfactant is present, it may be desirable for it to foam quickly and profusely, but to be fully depleted at an expected time to indicate that the used substrate may be discarded. If the water flow rate is very low (eg, zero or nearly zero), insufficient wetting of the surfactant contained in the substrate can cause the foam to start very slowly. On the other hand, if the water flow rate is too high, the surfactant can be washed too easily from the substrate, and

to attach a substrate to the bottom of a plastic funnel with the following measurements: an internal diameter (id) of 24mm at an outlet, an Id of 145mm at the top, a height of 135mm (from the top superior to the ice of a neck), a neck 20 mm long and a total volume of approximately 600 ml. Sufficient tension is applied to the substrate to ensure that it is completely flat, without applying it excessively. Tape or rubber bands are attached as close as possible to the funnel outlet to prevent backflow under water pressure. The funnel is then held in an annular holder over a sink. 600 ml of water at room temperature is measured in a test tube. Then, with one hand, the outlet of the funnel is blocked, the test substrate is pushed, and the water is quickly poured into the funnel. When the funnel is completely full, the hand is removed and the drain time, which is the time it takes for the water to exit the funnel, to the nearest tenth of a second is measured. The stopwatch stops when the water reaches the Neck Intersection and the sloping portion of the funnel. This process is repeated 5 times per test substrate, and the measurements are averaged for each substrate.

Substrates that exhibit long drain times (i.e., approximately 10 minutes or longer) can be tested by weighing the drained water over a set period of time (eg, 5 minutes) with a funnel filled with water and then using the Algebraic determination of the flow time of 600 ml of water. Thereafter, the flow rate of water in the opposite direction of the substrate is determined (unless the substrate is the same in both directions), and both results are averaged. For substrates with high surface tension with respect to water and small pores (that is, it is observed that the flux increases significantly with a * τ · *

A small amount of surfactant added) adds a sufficient amount of wetting agent to the water (eg, Dawrr® liquid)^iH* "P^ra'^ra"Tte crockery), at least a critical micellar concentration for water to flow through the substrate without the obstruction of wetting forces prior to testing. The water flow index is expressed in cm³/ cm²-s according to the equation: Water flow rate = (600 g of water) x (1 cm³/g)/((1.2 cm)² x (average time in seconds)).

B._Proof of consumption

To measure the consumption rate of an item or composition, a rotating drum (Lortone, Inc., Seattle, WA, USA model 33B or equivalent) with a 4-inch (102 mm) cylindrical rubber housing is used. diameter by 102 mm (4 inches) deep that has an internal volume of 825 cc. The housing rotates on the drum at 43 rpm. A tap water supply is obtained with a water hardness of approximately 7.5 grains and a conductivity of 100 to no more than

400 microsiemens per centimeter (pS / cm) and heated in a beaker with a receptacle at ° C. The water supply is maintained at the indicated temperature within 1 degree for the duration of the test. 200.0 g of water is added from the receptacle to the housing. An item or composition is weighed to obtain the initial weight, and the item or composition is added to the housing. The housing is sealed with its watertight lid, and the sealed housing is placed on the rotating drum for an exact time of 3 minutes. The housing is removed, uncovered, and the article or composition is recovered. The remaining water in the housing is stirred for a few seconds, and its conductivity and temperature are determined with a Mettler Toledo SevenMulti meter with an InLab 740 probe or equivalent. The surface of the article or composition is dried by pressing, not rubbing, with paper towels and light manual pressure for

If the article or composition transfers partially dissolved or dissolved components in addition to liquid water (e.g. For example, if a composition is a conventional bar soap, you can transfer a paste-like material), the transferred components should be removed, and the item or composition is considered dry when the visible transfer is no longer evident. The item or composition is weighed.

The housing is emptied and rinsed with hot tap water and dried to complete one (1) cycle. The cycle is repeated with the same article or composition 4 more times for a total of 5 cycles. The conductivity of the water container is determined at 30 ° C, 35 ° C, 40 ° C, and 45 ° C. With a new article of the same composition, a 1% solution is prepared by removing 1.00 grams of its soluble chemical composition and adding it to 99.00 grams of water from the container. The chemical composition is completely dissolved with stirring and heat as necessary. The conductivity of the 1% solution is determined at the same 4 temperatures. A 2% solution is prepared in the same way (2.00 grams of composition in 98.00 grams of water), and its conductivity is determined at the same 4 temperatures. The conductivity results are compared to the temperature for each solution (0%, 1% and 2%) and algebraic expressions are obtained for each one.

For each conductivity-temperature data for water in the housing obtained during each cycle, the regression for conductivity in 0%, 1% and 2% solutions is calculated at the temperature measured by the InLab 470 probe for each cycle. A second set of linear regressions is performed for each temperature obtained in the cycles by using the solution concentrations iN .-. Τιτυ Λ ·. · ,.)

This second regression is used_a ^ ada_J ^ JIipsiaíUIS., „« .. obtained in each cycle with its pair of conductivity value obtained as the input value of x to obtain y, which is the amount of dissolved solids in the article for each cycle. Dissolved solids for the 5 cycles are added, and divided by 5 to obtain the average dissolved solids. The value is multiplied by 1.67 to obtain the article consumption index, which is based on the relationship between this method and the consumption during the use of articles in an average of showers ad libde consumers.

C._ Tensile test of the substrate and the article

To measure the stiffness of a substrate and / or article, a tensile testing instrument is used with a TA-XT2Í texture analyzer (Texture Technologies Corp, NY,

USA ) Equipped with a load cell of at least 5 kg and adjustable upper and lower jaws in environmental conditions. An instrument reference length (the closest distance between jaws) is set to 50 mm. 25.4 mm (1 inch) wide strips are cut from the personal care item or water-insoluble substrate with a precision cutter in a machine direction (MD). (Note: The properties of an article can be determined by physically separating the personal care composition from the article substrates and cutting 25.4 mm (1 inch) wide strips of the removed personal care article. the cleaning composition If the strips are too short, the reference length of the Instrument is adjusted to accommodate the strips of the substrate, as the results are expressed in tension. Additionally, if the strips are too narrow, they are evaluated by normalizing, arithmetically, the results obtained to a width of 25.4 mm (1 inch).

The strips are attached to the jaws on the instrument, the instrument is programmed

The maximum force (grams) is recorded and the maximum force recorded is divided by the width to generate the ultimate tensile strength in g / mm width of the article or substrate. For materials that exceed the capacity of a load cell, the width of the strips is reduced or the capacity of the load cell is increased to measure stiffness and ultimate tensile strength.

D._ Dissolution rate test

A straight walled glass beaker with an internal diameter (id) of 63mm and an Inner height of 87mm is obtained (eg, Pyrex 250 ml (# 1000), widely available). 150 grams of distilled water at room temperature (24 ° C [75 ° Fj) is poured into the beaker, and a Teflon® coated magnetic stir bar is added to the beaker. (Note: The stir bar can be nominally 38mm (1.5 inches) long x 8mm (5/16 inches) in diameter, and octagonal when viewed from the end, and may have a 1/16 inch (1.6 mm) wide molded pivot around its center, where diameter may be approximately 9 mm [0.35 inch]) Examples of a suitable stir bar may include commercially available Spinbar® magnetic stir bars by Slgma Aldrich Corp. worldwide, which includes Milwaukee, Wl,

USA USA, and at www.sigmaaldrich.com.

The conductivity of the water is measured and recorded with a conductivity meter (eg, a Mettler-Toledo SevenMulti meter with lnLab740 probe). (Note:

Equipment Co, Cincinnati, OH, United States). The glass is centered on the stirrer, and the stirrer is turned on to obtain a constant rotational speed of 500 rpm and to establish a vortex in the water that is approximately 3 cm deep from the highest point of water at the edge of the glass at lowest point of air in the center of the vortex. The vortex is viewed from above to ensure that the beaker is centered and that the magnetic stir bar is centered in the vortex. Weigh 1.0 gram of a pressed or formed cleaning composition as a single unit and add it to the water near the edge of the glass, but without touching it. A timer is turned on and the water with the cleaning composition is allowed to stir for 1 minute.

The stirrer is turned off. The conductivity probe is inserted into the water in a location away from any undissolved material. The measurement is allowed to stabilize for a few seconds, and the conductivity is recorded. The agitator turns on again. The automatic clock is restarted when the digital reading passes 250 rpm. After another minute, the stirrer is turned off and the conductivity is measured and recorded in the same way as explained above. The agitator turns on again. The automatic clock is restarted when the digital reading passes 250 rpm. The process is repeated until a conductivity reading has been obtained for each minute of agitation, for 5 minutes.

After taking the 5-minute conductivity reading, the beaker is covered with a suitable watertight cover (eg, plastic wrap). Shake the beaker vigorously for approximately 1 minute to dissolve the remaining solids with a vortex type stirrer and / or moderate heating

The solution is cooled to npsnns dp 27. ísn-iEi. before the final measurement. The beaker is uncapped, the conductivity is measured, and the value is recorded as the final conductivity.

The fractional solution (f) at each time point is calculated with the equation: f = (conductivity - water conductivity) / (final conductivity water conductivity)

The dissolution half-life is calculated by fitting the fractional dissolution time series (6 points from 0 to 5 minutes) to a second-order polynomial, and an interpolated or extrapolated result is calculated for a time when a composition is semi-dissolved. (i.e. f = 0.5).

The half-life of solution can be a measure of the tendency of a composition to resist solubilization by water. Soap bars, for example, can have a dissolution half-life of 21.1 minutes (Ivory® ™ soap) and exhibit long life and a low rate of use during use without the need for substrates as permeability barriers. Liquid body soap may have a shorter half-life to dissolution than ¹/ 2 minute and may be unsuitable as a cleaning composition for some items.

A compression force (kg) is determined at a Tndíééde “dmprésion'ciene 1 mm / s over a depth of 5 mm, and ensures that the composition or personal care item forms a flat surface over the contact area with the ball probe near the center of the article or composition. Measurements are repeated as necessary (eg, at least 3 times) to obtain a representative average value. To determine the composition or article fit, the maximum observed force (kg) is divided by the maximum compression depth (5 mm). When using a 5 kg load cell, some samples may exceed capacity; in this case, the maximum compression depth will be less than the established 5mm depth specified in the procedure.

F._ Foam tests

JL_Manual foam test

A 2000 ml volumetric glass having an internal diameter of approximately 127 mm (5 inches) and a depth of approximately 190 mm (7.5 inches) is filled with 600 ml of warm tap water (40 ° C) having a hardness of water of approximately 0.12 g / l (7.5 grains per gallon) and conductivity between 100 to no more than 400 microsiemens per cm. The item is completely immersed in the water for 5 seconds, the item is removed from the water and the water is allowed to drain into the beaker for 5 seconds. The item is rubbed in the hands in a reciprocating motion for 50 seconds, the item is squeezed and rotated from side A to side B at the second mark of 10, 20, 30 and 40 seconds. Foam from hands and item is captured in 2000 ml volumetric beaker, removes as much foam from hand and item as

With a ruler, measure the height of the foam from the base of the foam (i.e. top of the water) to the top of the foam, repeat the measurement in 3 places around the side of the glass. The height values are averaged and used to calculate the foam volume, using the interior radius of the glass.

2._Piston foam test

The item is attached to the bottom of a modified potato masher (eg, as commonly marketed by OXO). The potato masher should be modified to support the weight on the top surface of the mash rack so that the combined weight of the potato masher and the added weight is 704 g. The upper handle of the crusher is attached to an instrument that will provide vertical movement, resulting in 16cm of vertical movement at a rate of 10.2 cm / s. However, the machine does not add downward force to the system in the vertical direction. A 2000 ml volumetric glass with an internal diameter of approximately 127 mm (5 inches) and a depth of approximately 190 mm (7.5 inches) is filled with 100 ml of warm tap water (40 ° C) having a hardness of water of approximately 0.12 g / l (7.5 grains per gallon) and conductivity between 100 to no more than 400 mlcrosiemens per centimeter. Place the potato masher in the glass and leave the cleaning article to soak in the water for 5 seconds. Then, with the potato masher attached to the machine, a vertical movement is supplied, the machine is turned on and 100 vertical movements are carried out from top to bottom. With a ruler, the height of the foam from the base of the foam (i.e. top of the water) to the top of the foam is measured, the measurement is repeated in 3 places around the side of the glass.

Cl_Proof of cantilever molding

Cantilever fit is a measure of the ability of an item to conform to a shape under an applied force. Cantilever fit is determined by creating an overhang with the article and measuring deflection under applied stress. Preferably, the length and width of the article is determined and the article is positioned as a cantilever such that% of the length protrudes beyond the support structure.

o A weight is attached to the cantilevered end of the article using paper clip clips, the total weight applied should represent the typical forces exerted on an article used for cleaning and can range from 0.05 to 0.75 kg. The cantilever deflection in the vertical direction is measured and divided by% of the length of the article and multiplied by 100 to obtain the cantilever fit value. Cantilever molding = 100 * (deflection / (0.75 * length)).

The method can be repeated by orienting the article so that% of the width protrudes beyond the support structure to determine the cantilever fit of the article in terms of the width of the article. Cantilever fit = 100 * (deflection / (0.75 * W))

In this embodiment, the cantilevered fit of an article can be determined, both in the machine direction and in the cross-machine direction, where the machine direction is defined as perpendicular to the direction in which the articles move to throughout the assembly process.

An article does not become conformable simply because a composition can break or fracture during testing.
