Title: Personal care articles comprising cationic polymer coacervate compositions

Description:
TECHNICAL FIELD  
       [0001] The present invention relates to disposable, personal care articles suitable for cleansing and/or therapeutically treating the skin, hair and any other sites in need of such treatment. These articles each comprise a water insoluble substrate comprising a nonwoven layer; and a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit composition comprising a safe and effective amount of a cationic polymer exhibiting a Relative Hydrophobic Contribution of from about 0.2 to about 1.0 and a safe and effective amount of an anionic surfactant wherein said composition forms a coacervate when said article is exposed to water.  
       [0002] Consumers use the articles by wetting them with water and rubbing them on the area to be cleansed and/or therapeutically treated (e.g. conditioned).  
       [0003] The invention also encompasses methods for cleansing and/or conditioning the skin and hair using the articles of the present invention.  
       BACKGROUND OF THE INVENTION  
       [0004] Personal care products, particularly cleansing and conditioning products, have traditionally been marketed in a variety of forms such as bar soaps, creams, lotions, and gels. Typically, these products have attempted to satisfy a number of criteria to be acceptable to consumers. These criteria include cleansing effectiveness, skin feel, mildness to skin, hair, and ocular mucosae, and lather volume. Ideal personal cleansers should gently cleanse the skin or hair, cause little or no irritation, and should not leave the skin or hair with a heavy buildup or overly dry when used frequently.  
       [0005] It is also highly desirable to deliver such cleansing and conditioning benefits from a disposable product. Disposable products are convenient because they obviate the need to carry or store cumbersome bottles, bars, jars, tubes, and other forms of clutter including cleansing products and other products capable of providing therapeutic or aesthetic benefits. Disposable products are also a more sanitary alternative to the use of a sponge, washcloth, or other cleansing implement intended for extensive reuse, because such implements can develop bacterial growth, unpleasant odors, and other undesirable characteristics related to repeated use.  
       [0006] The articles of the present invention surprisingly provide effective cleansing and/or therapeutic benefits to the skin and hair in a convenient, inexpensive, and sanitary manner. The present invention provides the convenience of not needing to carry, store, or use a separate implement (such as a washcloth or sponge), a cleanser and/or a therapeutic benefit product. These articles are convenient to use because they are in the form of either a single, disposable personal care article or multiple disposable articles useful for cleansing as well as application of a therapeutic or aesthetic benefit agent. Moreover, these articles are suitable for use within or in conjunction with another personal care implement that is designed for more extensive use. In this instance, the articles of the present invention are disposed within or attached to a separate personal care implement that is not readily disposable, e.g., a bath towel or washcloth. In addition, the disposable articles of the present invention may be removeably attached to a handle or grip suitable for moving the article over the surface to be cleansed and/or therapeutically treated (e.g., conditioned).  
       [0007] Although in preferred embodiments the articles of the present invention are suitable for personal care applications, they may also be useful in a variety of other industries such as the automotive care, marine vehicle care, household care, animal care, etc. where surfaces or areas are in need of cleansing and/or application of a benefit agent, e.g., wax, conditioner, UV protectant, etc.  
       [0008] In preferred embodiments of the present invention, the articles are suitable for personal care applications and are useful for cleansing and/or conditioning the skin, hair, and similar keratinous surfaces in need of such treatment. Consumers use these articles by wetting them with water and rubbing them on the area to be treated. The article consists of a water insoluble substrate and a therapeutic benefit component. Without being limited by theory, it is believed that the nonwoven layer of the substrate, particularly, enhances cleansing and exfoliation, and optimizes delivery and deposition of a therapeutic or aesthetic benefit agent that might be contained within the article.  
       SUMMARY OF THE INVENTION  
       [0009] The present invention relates to a substantially dry, disposable personal care article comprising:  
       [0010] a) a water insoluble substrate comprising a nonwoven layer; and  
       [0011] b) a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit composition comprising:  
       [0012] 1) a safe and effective amount of a cationic polymer exhibiting a Relative Hydrophobic Contribution of from about 0.2 to about 1.0;  
       [0013] 2 ) a safe and effective amount of an anionic surfactant; wherein said composition forms a coacervate when said article is exposed to water.  
       [0014] The present invention also relates to a method of cleansing and/or conditioning the skin and hair which comprises the steps of: a) wetting such articles with water and b) contacting the skin or hair with the wetted articles.  
       [0015] All percentages and ratios used herein, unless otherwise indicated, are by weight and all measurements made are at 25° C., unless otherwise designated.

       [0016] In the description of the invention various embodiments and/or individual features are disclosed. As will be apparent for the skilled practitioner all combinations of such embodiments and features are possible and can result in preferred executions of the invention.  
       [0017] All documents referred to herein, including patents, patent applications, and printed publications, are hereby incorporated by reference in their entirety in this disclosure.  
       DETAILED DESCRIPTION OF THE INVENTION  
       [0018] As used herein, “disposable” is used in its ordinary sense to mean an article that is disposed or discarded after a limited number of usage events, preferably less than 25, more preferably less than about 10, and most preferably less than about 2 entire usage events.  
       [0019] As used herein, “substantially dry” means that the articles of the present invention exhibit a Moisture Retention of less than about 0.95 gms, preferably less than about 0.75 gms, even more preferably, less than about 0.5 gms, even more preferably less than about 0.25 gms, even still more preferably less than about 0.15 gms, and most preferably, less than about 0.1 gms. The determination of the Moisture Retention is discussed later.  
       [0020] The personal care articles of the present invention comprise the following essential components.  
       WATER INSOLUBLE SUBSTRATE  
       [0021] The articles of the present invention comprise a water insoluble substrate comprising at least one nonwoven layer or ply. Preferably, this nonwoven layer is non-scouring. As used herein, “non-scouring” means that the layer exhibits an Abrasive Value of greater than about 15, preferably greater than about 30, more preferably greater than about 50, even more preferably greater than about 70, and most preferably greater than about 80 as determined by the Abrasiveness Value Methodology described below. Preferably, the substrate layers are soft yet invigorating to the skin of the consumer when used.  
       [0022] Without being limited by theory, the water insoluble substrate enhances cleansing and/or therapeutic treatment. The substrate can have the same or differing textures on each side such that the gripping side of the article is the same or a different texture as the skin/site contact side. The substrate may act as an efficient lathering and exfoliating implement. By physically coming into contact with the skin or hair, the substrate significantly aids in cleansing and removal of dirt, makeup, dead skin, and other debris. In preferred embodiments, however, the substrate is non-scouring or nonabrasive to the skin.  
       [0023] Materials suitable for the nonwoven layer are selected from the group consisting of cellulosic nonwovens, sponges (i.e., both natural and synthetic), formed films, battings, and combinations thereof. Preferably, the layer comprises materials selected from the group consisting of cellulosic nonwovens, formed films, lofty battings, foams, sponges, reticulated foams, vacuum-formed laminates, scrims, polymeric nets, and combinations thereof. More preferably, the nonwoven layer comprises materials selected from the group consisting of cellulosic nonwovens, non-lofty nonwovens, formed films, lofty battings, and combinations thereof. As used herein, “nonwoven” means that the layer does not comprise fibers which are woven into a fabric but the layer need not comprise fibers at all, e.g., formed films, sponges, foams, scrims, etc. When the layer comprises fiber, the fibers can either be random (i.e., randomly aligned) or they can be carded (i.e., combed to be oriented in primarily one direction). Furthermore, the layer can be a composite material composed of a combination of additional layers, i.e., plies, of random and carded fibers.  
       [0024] In one embodiment, the nonwoven layer of the substrate comprises batting. Preferably, the nonwoven layer is lofty, non-scouring, and is of low-density. As used herein, “lofty” means that the layer has density of from about 0.00005 g/cm 3  to about 0.1 g/cm 3 , preferably from about 0.001 g/cm 3  to about 0.09 g/cm 3  and a thickness of from about 0.04 inches to about 2 inches at 5 gms/in 2  The nonwoven layer which comprises batting preferably comprises synthetic materials. As used herein, “synthetic” means that the materials are obtained primarily from various man-made materials or from natural materials which have been further altered. Suitable synthetic materials include, but are not limited to, acetate fibers, acrylic fibers, cellulose ester fibers, modacrylic fibers, polyamide fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon fibers, polyethylene foam, polyurethane foam, and combinations thereof. Preferred synthetic materials, particularly fibers, may be selected from the group consisting of nylon fibers, rayon fibers, polyolefin fibers, polyester fibers, and combinations thereof. Preferred polyolefin fibers are fibers selected from the group consisting of polyethylene, polypropylene, polybutylene, polypentene, and combinations and copolymers thereof. More preferred polyolefin fibers are fibers selected from the group consisting of polyethylene, polypropylene, and combinations and copolymers thereof. Preferred polyester fibers are fibers selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, polycyclohexylenedimethylene terephthalate, and combinations and copolymers thereof. More preferred polyester fibers are fibers selected from the group consisting of polyethylene terephthalate, polybutylene terephthalate, and combinations and copolymers thereof. Most preferred synthetic fibers comprise solid staple polyester fibers which comprise polyethylene terephthalate homopolymers. Suitable synthetic materials may include solid single component (i.e., chemically homogeneous) fibers, multiconstituent fibers (i.e., more than one type of material making up each fiber), and multicomponent fibers (i.e., synthetic fibers which comprise two or more distinct filament types which are somehow intertwined to produce a larger fiber), and combinations thereof., Preferred fibers include bicomponent fibers, multiconstituent fibers, and combinations thereof. Such bicomponent fibers may have a core-sheath configuration or a side-by-side configuration. In either instance, the nonwoven layer may comprise either a combination of fibers comprising the above-listed materials or fibers which themselves comprise a combination of the above-listed materials.  
       [0025] For the core-sheath fibers, preferably, the cores comprise materials selected from the group consisting of polyesters, polyolefins having a T g  of at least about 10° C. higher than the sheath material, and combinations thereof. Conversely, the sheaths of the bicomponent fibers preferably comprise materials selected from the group consisting of polyolefins having a T g  of at least about 10° C. lower than the core material, polyesters polyolefins having a T g  of at least about 10° C. lower than the core material, and combinations thereof. More preferably, the core comprises a polyester material while the sheath comprises a polyethylene material.  
       [0026] In any instance, side-by side configuration or core-sheath configuration, the fibers of the nonwoven layer may exhibit a helical or spiral or crimped configuration, particularly the bicomponent type fibers.  
       [0027] The batting nonwoven layer may also comprise natural fibers.  
       [0028] Furthermore, the fibers of the batting nonwoven layer preferably have an average thickness of from about 0.5 microns to about 150 microns. More preferably, the average thickness of the fibers are from about 5 microns to about 75 microns. In an even more preferred embodiment, the average thickness of the fibers are from about 8 microns to about 40 microns. Furthermore, the fibers of the nonwoven layer may be of varying sizes, i.e., the fibers of the nonwoven layer may comprise fibers having different average thicknesses. Also, the cross section of the fibers can be round, flat, oval, elliptical or otherwise shaped.  
       [0029] In another embodiment, the nonwoven layer of the present invention may comprise a composite material, i.e., a material having one or more plies of the same or different suitable materials merely superimposed physically, joined together continuously (e.g., laminated, etc.) or in a discontinuous pattern, or by bonding at the external edges (or periphery) of the layer and/or at discrete loci. For instance, the nonwoven layer may further comprise composite materials selected from the group consisting of fibrous nonwovens, sponges, foams, reticulated foams, polymeric nets, scrims, vacuum-formed laminates, formed films and formed film composite materials. It is preferred that the nonwoven layer comprise a formed film composite material comprising at least one formed film and at least one nonwoven wherein the layer is vacuum formed. A suitable formed film composite material includes, but is not limited to, a vacuum laminated composite formed film material formed by combining a carded polypropylene nonwoven having a basis weight of 30 gsm with a formed film.  
       [0030] In another embodiment, the nonwoven layer is apertured. The apertures in the nonwoven layer of the water insoluble substrate will generally range in average diameter between about 0.5 mm and 5 mm. More preferably, the apertures will range in size between about 1 mm to 4 mm in average diameter. Preferably, no more than about 10% of the apertures in the nonwoven layer of the substrate will fall outside these size ranges. More preferably, no more than about 5% of the apertures in the nonwoven layer will fall outside these size ranges. For apertures which are not circular in shape, the “diameter” of the aperture refers to the diameter of a circular opening having the same surface area as the opening of the non-circular shaped aperture.  
       [0031] Within the nonwoven layer, the apertures will generally occur at a frequency of from about 0.5 to 12 apertures per straight linear centimeter. More preferably, the apertures in the surface of the layer will occur at a frequency of from about 1.5 to 6 apertures per straight linear centimeter.  
       [0032] The apertures must at least be placed within the nonwoven layer. Such apertures need not protrude completely through one surface of the nonwoven layer to the other. They, however, may do so. Additionally, apertures may or may not be placed in the nonwoven layer of the substrate such that the entire article is apertured through it&#39;s entire volume.  
       [0033] Apertures may be formed in the nonwoven layer of the water insoluble substrate as such a substrate, or layer thereof, is being formed or fabricated. Alternatively, apertures may be formed in the nonwoven layer after the substrate comprising the layer has been completely formed.  
       [0034] The nonwoven layer may comprise a variety of both natural and synthetic fibers or materials. As used herein, “natural” means that the materials are derived from plants, animals, insects or byproducts of plants, animals, and insects. The conventional base starting material is usually a fibrous web comprising any of the common synthetic or natural textile-length fibers, or combinations thereof.  
       [0035] Nonlimiting examples of natural materials useful in the present invention include, but are not limited to, silk fibers, keratin fibers and cellulosic fibers. Nonlimiting examples of keratin fibers include those selected from the group consisting of wool fibers, camel hair fibers, and the like. Nonlimiting examples of cellulosic fibers include those selected from the group consisting of wood pulp fibers, cotton fibers, hemp fibers, jute fibers, flax fibers, and combinations thereof. Cellulosic fiber materials are preferred in the present invention.  
       [0036] Nonlimiting examples of synthetic materials useful in the present invention include those selected from the group consisting of acetate fibers, acrylic fibers, cellulose ester fibers, modacrylic fibers, polyamide fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon fibers, polyethylene foam, polyurethane foam, and combinations thereof. Examples of suitable synthetic materials include acrylics such as acrilan, creslan, and the acrylonitrile-based fiber, orlon; cellulose ester fibers such as cellulose acetate, arnel, and acele; polyamides such as nylons (e.g., nylon 6, nylon 66, nylon 610, and the like); polyesters such as fortrel, kodel, and the polyethylene terephthalate fiber, polybutylene terephalate fiber, dacron; polyolefins such as polypropylene, polyethylene; polyvinyl acetate fibers; polyurethane foams and combinations thereof. These and other suitable fibers and the nonwovens prepared therefrom are generally described in Riedel, “Nonwoven Bonding Methods and Materials,”  Nonwoven World  (1987);  The Encyclopedia Americana,  vol. 11, pp. 147-153, and vol. 26, pp. 566-581 (1984); U.S. Pat.

       [0037] Nonwovens made from natural materials consist of webs or sheets most commonly formed on a fine wire screen from a liquid suspension of the fibers. See C. A. Hampel et al.,  The Encyclopedia of Chemistry,  third edition, 1973, pp. 793-795 (1973);  The Encyclopedia Americana,  vol. 21, pp. 376-383 (1984); and G. A.

       [0040] Methods of making nonwovens are well known in the art. Generally, these nonwovens can be made by air-laying, water-laying, meltblowing, coforming, spunbonding, or carding processes in which the fibers or filaments are first cut to desired lengths from long strands, passed into a water or air stream, and then deposited onto a screen through which the fiber-laden air or water is passed. The resulting layer, regardless of its method of production or composition, is then subjected to at least one of several types of bonding operations to anchor the individual fibers together to form a self-sustaining web. In the present invention the nonwoven layer can be prepared by a variety of processes including, but not limited to, air-entanglement, hydroentanglement, thermal bonding, and combinations of these processes.  
       [0041] Nonwovens made from synthetic materials useful in the present invention can be obtained from a wide variety of commercial sources.

Preferred non-woven substrate materials have a basis weight of about from 24 gsm to about 96 gsm, more preferably from about 36 gsm to about 84 gsm, and most preferably from about 42 gsm to about 78 gsm.  
       [0042] The nonwoven layer may also be a polymeric mesh sponge as described in European Pat. Application No. EP 702550A1 published Mar. 27, 1996, which is incorporated by reference herein in its entirety. Such polymeric mesh sponges comprise a plurality of plies of an extruded tubular netting mesh prepared from a strong flexible polymer, such as addition polymers of olefin monomers and polyam ides of polycarboxylic acids.  
       [0043] The nonwoven layer may also comprise formed films and composite materials, i.e., multiply materials containing formed films. Preferably, such formed films comprise plastics which tend to be soft to the skin. Suitable soft plastic formed films include, but are not limited to, polyolefins such as low density polyethylenes (LDPE). In such cases where the nonwoven layer comprises a plastic formed film, it is preferred that the nonwoven layer be apertured, e.g., macroapertured or microapertured, such that the layer is fluid permeable. In one embodiment, the nonwoven layer comprises a plastic formed film which is only microapertured. The surface aberrations of the microapertures, i.e., the male side, are preferably located on the interior surface of the second layer and preferably face toward the inside of the substrate, i.e., toward the cleansing component. In certain embodiments which include apertures having petal-like edged surface aberrations, without being limited by theory, it is believed that when the surface aberrations of the apertures face toward the surfactant-containing cleansing component and/or therapeutic benefit component, the application of pressure by the hand to the article allows the petal-like edges of the surface aberrations to fold inward thereby creating numerous valves on the interior surface of the layer which in effect meter out the cleansing component and/or therapeutic benefit component contained within the article thereby extending the article&#39;s useful life.  
       [0044] In another embodiment, the nonwoven layer comprises a plastic formed film which is both microapertured and macroapertured. In such embodiments, the nonwoven layer is well-suited to contact the area to be cleansed given the cloth-like feel of such microapertured films. Preferably, in such an embodiment, the surface aberrations of the microapertures face opposite of the surface aberrations of the macroapertures on the nonwoven layer. In such an instance, it is believed that the macroapertures maximize the overall wetting/lathering of the article by the three-dimensional thickness formed from the surface aberrations which are under constant compression and decompression during the use of the article thereby creating lathering bellows.  
       [0045] In any case, the nonwoven layer comprising a formed film preferably has at least about 100 apertures/cm 2 , more preferably at least 500 apertures/cm 2 , even still more preferably at least about 1000 apertures/cm 2 , and most preferably at least about 1500 apertures/cm 2  of the substrate. More preferred embodiments of the present invention include a nonwoven layer which has water flux rate of from about 5 cm 3 /cm 2 -s to about 70 cm 3 /cm 2 -s, more preferably from about 10 cm 3 /cm 2 -s to about 50 cm 3 /cm 2 -s and most preferably from about 15 cm 3 /cm 2 -s to about 40 cm 3 /cm 2 -s.  
       [0046] Suitable formed films and formed film-containing composite materials useful in the nonwoven layer of the present invention include, but are not limited to, those disclosed in U.S. Pat. No. 4,342,314 issued to Radel et al. on Aug. 3, 1982, commonly assigned co-pending application U.S. Ser. No. 08/326,571 and PCT Application No. US95/07435, filed Jun. 12, 1995 and published Jan. 11, 1996, and U.S. Pat. No. 4,629,643, issued to Curro et al. on Dec. 16, 1986, each of which is incorporated by reference herein in its entirety. Furthermore, the nonwoven layer may be a formed film composite material comprising at least one formed film and at least one nonwoven wherein the layer is vacuum formed. A suitable formed film composite material includes, but is not limited to, a vacuum laminated composite formed film material formed by combining a carded polypropylene nonwoven having a basis weight of 30 gsm with a formed film.  
       [0047] Additionally, the nonwoven layer and any additional layers are preferably bonded to one another in order to maintain the integrity of the article. This bonding may consist of spot bonding (e.g., hot point bonding), continuous joining (e.g., laminated, etc.) in a discontinuous pattern, or by bonding at the external edges (or periphery) of the layers and/or at discrete loci or combinations thereof. When spot bonding is used in the present articles, it is preferred that the spot bonds are separated by a distance of not less than about 1 cm. In any instance, however, the bonding may be arranged such that geometric shapes and patterns, e.g. diamonds, circles, squares, etc., are created on the exterior surfaces of the layers and the resulting article.  
       [0048] It is also envisioned in the articles of the present invention that the nonwoven layer and any additional layers may be surface modified to form single composite layer having 2 sides with different textures. Thus, in effect, the water insoluble substrate can be construed as comprising a single composite layer with dual textured sides or surfaces.  
       [0049] In any event, it is preferred that the bonded area present between the nonwoven layer and any additional layers be not greater than about 50% of the total surface area of the layers, preferably not greater than about 15%, more preferably not greater than about 10%, and most preferably not greater than about 8%.  
       [0050] Each of the layers discussed herein comprises at least two surfaces, namely an interior surface and an exterior surface, each of which may have the same or different texture and abrasiveness. Preferably, the articles of the present invention comprise substrates and therefore layers which are soft to the skin. However, differing texture substrates can result from the use of different combinations of materials or from the use of different manufacturing processes or a combination thereof. For instance, a dual textured water insoluble substrate can be made to provide a personal care article with the advantage of having a more abrasive side for exfoliation and a softer, absorbent side for gentle cleansing and therapeutic treatment. In addition, the separate layers of the substrate can be manufactured to have different colors, thereby helping the user to further distinguish the surfaces.  
       [0051] Furthermore, each of the layers of the articles as well as the articles themselves may be made into a wide variety of shapes and forms including flat pads, thick pads, thin sheets, ball-shaped implements, irregularly shaped implements. The exact size of the layers will depend upon the desired use and characteristics of the article and may range in surface area size from about a square inch to about hundreds of square inches. Especially convenient layer and article shapes include, but are not limited to, square, circular, rectangular, hourglass, mitt-type or oval shapes having a surface area of from about 5 in 2  to about 200 in 2 , preferably from about 6 in 2  to about 120 in 2 , and more preferably from about 15 in 2  to about and a thickness of from about 0.5 mm to about 50 mm, preferably from about 1 mm to about 25 mm, and more preferably from about 2 mm to about 20 mm.  
       Abrasiveness Value Methodology  
       [0052] The Abrasiveness Value indicates the “non-scouring” property of the nonwoven layers of the present articles. The nonwoven layers of the present invention are mildly exfoliating but are not rough to the skin. Therefore, the Abrasiveness Value determination involves rubbing the substrate along a test surface using a mechanical device and then examining the resulting scratch marks produced on the test surface using different analysis techniques.  
       [0053] The following equipment is needed for the methodology.  
       [0054] 1. Martindale Toothbrush Wear and Abrasion Tester: Model 103, serial nos. 103-1386/2 upwards.  
       [0055] Martindale 07-01-88 made by James H. Heal and Co. Ltd. Textile Testing and QC Equipment. Foot area: 43×44 mm. 1 Kg weight.  
       [0056] 2. Capped Polystyrene strips 1×8 cm. Clear general purpose polystyrene layer on white High Impact Polystyrene, e. g., EMA Model Supplies SS-20201L.  
       [0057] 3. Substrates to be tested.  
       [0058] 4. Glossmeter, e.g. Sheen Tri-Microgloss 20-60-85  
       [0059] Prepare the polystyrene strips for scratching by removing plastic protective coating from the side to be scratched and rinsing with ethanol (do not use tissue). Place the strip onto non abrasive surface and allow strip to dry in the air. Then, attach the polystyrene strip to the base of a Martindale wear tester with tape along the edges. Align the strip centrally under the path of the scrubbing device, with the length of the strip in the direction of movement. Cut a 2.5″×2.5″ substrate sample. Attach the substrate sample to the scrubbing foot of the Martindale, with double sided tape, aligning the machine direction of the substrate with the direction of travel. Secure the scrubbing foot assembly into the instrument with the screws supplied. Slot 1 Kg weight on to the top of the scrubbing foot assembly and ensure the scrubbing foot moves only in one direction (forward and backwards). Cover the entire Martindale with a safety screen. Set the machine to perform 50 cycles in 1 minute and allow to run. (Frequency=0.833 Hz). Once the machine has stopped take off the footer assembly and lift the polystyrene strip off the base of the machine. Label the polystyrene indicating the substrate used and store in a plastic bag.  
       [0060] Next, the strips are analyzed. The strips are placed on a black construction paper background and at least 5 samples of the same substrate are analyzed to get a reproducible average. The Glossmeter is placed orthogonally (such that light beam is at right angles to scratches) and centrally over scratched side of the polystyrene strip. A 20° angle is selected and the sample is measured yielding the Abrasiveness Value. As the Abrasiveness Value decreases the scratchiness or scouring property of a substrate increases.  
       THERAPEUTIC BENEFIT COMPONENT  
       [0061] The articles of the present invention further comprise a safe and effective amount of a therapeutic benefit component. The benefit component is disposed adjacent to the water insoluble substrate and comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit composition. The benefit composition further comprises a safe and effective amount of a cationic polymer exhibiting a Relative Hydrophobic Contribution of from about 0.2 to about 1.0 and a safe and effective amount of an anionic surfactant wherein said composition forms a coacervate when the article is exposed to water.  
       Cationic Polymer  
       [0062] The personal care compositions of the present invention comprise a safe and effective amount of cationic polymer having a Relative Hydrophobic Contribution of from about 0.2 to about 1.0. More preferably, the cationic polymer has a Relative Hydrophobic Contribution of from about 0.3 to about 0.95 and most preferably from about 0.4 to about 0.9. Preferably, the cationic polymer is a polyamine polymer which is hydrophobically or hydrophilically modified.  
       [0063] The Relative Hydrophobic Contribution (RHC) is a calculated value for a given polymer based on the method for HLB determination detailed in R. Sowada and J. C. McGowan, “Calculation of HLB Values,” Tenside Surf. Det. 29 (1992) 2. The RHC may be determined using the following formula: 
       RHC=Degree of Substitution (D)×Hydrophobicity of Substituent (H) 
       [0064] where  
       [0065] D is a fraction and  
       [0066] H=(methyl groups per substituent) X (HLB M  group number for methyl group=0.658)+(methylene groups per substituent) X (HLB M  group number for methylene group=0.475)+(phenyl groups per substituent) X (HLB M  group number for phenyl group=2.231)+(amide groups per substituent) X (HLB M  group number for amide group=−2.136).  
       [0067] For instance, a benzyl group which is substituted on 25% of the monomers would have an RHC of 0.25× (2.231+0.475)=0.68.  
       [0068] The cationic polymer preferably exhibits a charge density of greater than about 0.05 meq/gm, more preferably, greater than about 0.1 meq/gm, even more preferably, greater than about 0.2 meq/gm, even more preferably, greater than about 0.5 meq/gm, and most preferably, greater than about 1 meq/gm.  
       [0069] The molecular weight of the cationic polymer is preferably greater than about 250, more preferably, greater than about 350, even more preferably greater than about 450, and most preferably, greater than about 500.  
       [0070] Preferred cationic polymers may be selected from the group consisting of natural backbone quaternary ammonium polymers, synthetic backbone quaternary ammonium polymers, natural backbone amphoteric type polymers, synthetic backbone amphoteric type polymers, and combinations thereof.  
       [0071] More preferably, the cationic polymer is selected from the group consisting of natural backbone quaternary ammonium polymers selected from the group consisting of Polyquaternium-4, Polyquaternium-10, Polyquaternium-24, PG-hydroxyethylcellulose alkyldimonium chlorides, guar hydroxypropyltrimonium chloride, hydroxypropylguar hydroxypropyltrimonium chloride, and combinations thereof; synthetic backbone quaternary ammonium polymers selected from the group consisting of Polyquaternium-2, Polyquaternium-6, Polyquaternium-7, Polyquaternium-11, Polyquaternium-16, Polyquaternium-17, Polyquaternium-18, Polyquaternium-28, Polyquaternium-32, Polyquaternium-37, Polyquaternium-43, Polyquaternium-44, Polyquaternium-46, polymethacylamidopropyl trimonium chloride, acrylamidopropyl trimonium chloride/acrylamide copolymer, and combinations thereof; natural backbone amphoteric type polymers selected from the group consisting of chitosan, quaternized proteins, hydrolyzed proteins, and combinations thereof; synthetic backbone amphoteric type polymers selected from the group consisting of Polyquaternium-22, Polyquaternium-39, Polyquaternium-47, adipic acid/dimethylaminohydroxypropyl diethylenetriamine copolymer, polyvinylpyrrolidone/dimethylyaminoethyl methacyrlate copolymer, vinylcaprolactam/polyvinylpyrrolidone/dimethylaminoethylmethacrylate copolymer, vinaylcaprolactam/polyvinylpyrrolidone/dimethylaminopropylmethacrylamide terpolymer, polyvinylpyrrolidone/dimethylaminopropylmethacrylamide copolymer, polyamine, and combinations thereof; and combinations thereof. Even more preferably, the cationic polymer is a synthetic backbone amphoteric type polymer. Even still more preferably, the cationic polymer is a polyamine.  
       [0072] When the cationic polymer is a polyamine, it is preferred that the cationic polyamine polymer be selected from the group consisting of polyethyleneimines, polyvinylamines, polypropyleneimines, polylysines and combinations thereof. Even more preferably, the cationic polyamine polymer is a polyethyleneimine.  
       [0073] In certain embodiments in which the cationic polymer is a polyamine, the polyamine may be hydrophobically modified. In this instance, the cationic polyamine polymer is selected from the group consisting of benzylated polyamines, ethoxylated polyamines, propoxylated polyamines, alkylated polyamines, amidated polyamines, esterified polyamines and combinations thereof. The coacervate-forming composition comprises from about 0.01% to about 20%, more preferably from about 0.05% to about 10%, and most preferably from about 0.1% to about 5%, by weight of the coacervate-forming composition, of the cationic polymer.  
       [0074] The compositions of the present invention preferably contain 0.01% to about 20%, more preferably from about 0.05% to about 10%, and most preferably from about 0.1% to about 5%, by weight of the composition, of the cationic polymer.  
       Anionic Surfactant  
       [0075] The coacervate compositions of the present invention also comprise an anionic surfactant. Without being limited by theory, it is believed that the anionic surfactant interacts with the cationic polymer to partially reduce cationic charge density, decreasing solubility and enhancing deposition on skin. The compositions preferably comprise from about 10% to about 1,000%, preferably from about 50% to about 600%, and more preferably from about 100% to about 250%, based on the weight of the water insoluble substrate, of the anionic surfactant.  
       [0076] A wide variety of anionic surfactants are suitable for use in the compositions of the present invention. See, e.g., U.S. Pat. No. 2,929,678, issued to Laughlin et al. on Dec. 30, 1975. Nonlimiting examples of anionic surfactants include the acyl isethionates (e.g., C, 2 -C 30 ), alkyl and alkyl ether sulfates and salts thereof, alkyl and alkyl ether phosphates and salts thereof, alkyl methyl taurates (e.g., C 12 -C 30 ), monoalkanol amine phosphates and soaps (e.g., alkali metal salts like sodium or potassium salts) of fatty acids. Preferably, for the coacervate-forming composition, the anionic surfactant is selected from the group consisting of sarcosinates, glutamates, sodium alkyl sulfates, ammonium alkyl sulfates, sodium alkyleth sulfates, ammonium alkyleth sulfates, ammonium laureth-n-sulfates, sodium laureth-n-sulfates, isethionates, glycerylether sulfonates, sulfosuccinates, monoalkanol amine phosphates and combinations thereof. More preferably, the anionic surfactant is selected from the group consisting of sodium lauroyl sarcosinate, monosodium lauroyl glutamate, sodium alkyl sulfates, ammonium alkyl sulfates, sodium alkyleth sulfates, ammonium alkyleth sulfates, monoalkanol amine phosphates, and combinations thereof.  
       [0077] Without being limited by theory, it is believed that the cationic polymer and anionic surfactant coexist in the form of a coacervate when exposed to an aqueous medium. As used herein, “coacervate” means an associative phase separation of oppositely charged polymer and surfactant or polymer and polymer caused by product dilution. The result is an aqueous gel-like material which is formed, the coacervate. Once formed, the coacervates alone in the present compositions may improve the appearance of dry skin once applied. Furthermore, such coacervates may also serve as mechanisms for deposition of a therapeutic benefit agents thereby facilitating the substantivity of such agents to the skin. As the substantivity of the agent to the skin and/or hair is increased the effectiveness of the agent is increased.  
       pH  
       [0078] When the article is exposed to water, the therapeutic benefit compositions of the present invention exhibit a pH of from about 4 to about 10. Preferably, the pH is from about 4.5 to 9.5 and more preferably from about 5 to 9.  
       Surface to Saturation Ratio Methodology  
       [0079] The articles of the present invention comprise a therapeutic benefit component which is substantially on the surface of the substrate. By “substantially on the surface of the substrate” is meant that the surface to saturation ratio is greater than about 1.25, preferably greater than about 1.5, more preferably greater than about 2.0, even more preferably greater than about 2.25, and most preferably greater than 2.5. The surface to saturation ratio is a ratio of the measurement of benefit agent on the surface of the substrate. These measurements are obtained from Attenuated Total Reflectance (ATR) FT-IR Spectroscopy the use of which is well known to one skilled in the art of analytical chemistry.  
       [0080] Many conventional methods of application of conditioning agents to substrates employ processes and/or product rheologies unsuitable for the purposes of the present invention. For example, a process to dip the substrate web in a fluid bath of conditioning agent and then squeeze the substrate web through metering rolls, so called “dip and nip” processing, applies conditioning agent through the entire substrate and therefore does not afford opportunity for effective direct transfer of the composition off the cloth and onto another surface during use. Furthermore, many of the articles of the present invention utilize sufficient loadings of conditioning agent onto substrates to provide an effective whole body benefit, usually requiring about 100-200% loading rates based on the weight of the dry substrate. Known personal care implements that use these high loading levels essentially avoid dealing with aesthetic issues that can result from these high loadings by distributing the loading evenly throughout the substrate, including the substrate interior. Applicants have surprisingly found that high loadings of conditioning agent can be maintained on the surface of the article, thus advantageously affording opportunity for direct transfer of the benefit agents from the substrate to the surface to be treated during use, while delivering improved aesthetics by the compositions of the present invention.  
       [0081] The procedure to obtain the measurements is as follows:  
       Instrumental Setup  
       [0082] A BioRad FTS-7 spectrometer, manufactured by Bio Rad Labs, Digital Laboratory Division, located in Cambridge, Mass., is used to collect the infrared spectra. Typically, the measurements consist of 100 scans at 4 cm −1  resolution. The collection optics consist of a flat 60 deg ZnSe ATR crystal, manufactured by Graseby Specac, Inc., located in Fairfield, Conn. Data is collected at 25° C. and analyzed using Grams 386 software, distributed by Galactic Industries Corp., located in Salem, N.H. Prior to measurement the crystal is cleaned with a suitable solvent. The sample is placed onto the ATR crystal and held under constant 4 kilogram weight.  
       Experimental Procedure  
       [0083] (1) Measure the reference (background) spectrum of the cleaned, air dried cell.  
       [0084] (2) First, select a substrate with no benefit agents applied to it, the substrate selected comprising the external surface of the article. Place substrate on top of the ATR crystal., external surface against the crystal. First lay the substrate flat on the measuring platform. Then place a 4 kg. weight on top of the substrate. Then, measure the spectrum (typically 100 scans at 4 cm −1  resolution). The substrate acts as an internal standard because the absorbancy of the substrate alone is thus identified. Identify the main substrate peaks and wavenumbers.  
       [0085] (3) Repeat the procedure for the substrate of the article with benefit agent applied to it. Identify the primary benefit agent&#39;s peak heights, which are the highest observed peaks that either do not correspond to a substrate peak as observed previously; or which may correspond to a previously observed substrate peak but which exhibit the greatest percentage increase in absorbance due to presence of the conditioning agent. Record the wavenumber and absorbance of several benefit agent peaks.  
       [0086] (4) Select the substrate peak from the spectra determined in step 3 which occurs at a wavenumber determined in step 2, but which does not correspond to one of the primary benefit agent peaks selected in step 3. Record the wavenumber selected and the absorbance from the absorbance spectrum in step 3.  
       [0087] (5) Calculate the ratio of each benefit agent&#39;s peak height determined in step 3 to the substrate&#39;s peak height determined in step 4. The highest number of the group represents the surface to saturation ratio for the article.  
       [0088] The following contain some examples:  
                                                   Substrate Peak       Conditioner           Substrate*   and Peak Ht.   Conditioner   Peak Ht.

       Moisture Retention Methodology  
       [0089] As described above, the articles of the present invention are considered to be “substantially dry”. As used herein, “substantially dry” means that the articles of the present invention exhibit a Moisture Retention of less than about 0.95 gms, preferably less than about 0.75 gms, even more preferably, less than about 0.5 gms, even more preferably less than about 0.25 gms, even still more preferably less than about 0.15 gms, and most preferably, less than about 0.1 gms. The Moisture Retention is indicative of the dry feel that users perceive upon touching the articles of the present invention as opposed to the feel of “wet” wipes.  
       [0090] In order to determine the Moisture Retention of the present articles and other disposable substrate-based products, the following equipment and materials are needed.  
                                      Bounty White Paper Towel   Procter &amp; Gamble SKU 37000 63037           Basis Weight = 42.14 gsm       Balance   Accurate to 0.0 g       Lexan   0.5″ thickness           large enough to cover samples completely           and weighs 1000 g       Weight   A 2000 g weight or combination to equal           2000 g                  
 
       [0091] Next, weigh two paper towels separately and record each weight. Place one paper towel on flat surface (e.g. lab bench). Place the sample article on top of that towel. Place the other paper towel on top of sample article. Next, place the Lexan and then the 2000 g weight(s) on top of the sandwiched sample article. Wait 1 minute. After the minute, remove weight(s) and Lexan. Weigh the top and bottom paper towel and record the weight.  
       [0092] Calculate the Moisture Retention by subtracting the initial paper towel weight from the final weight (after 1 minute) for both the top and bottom paper towels. Add the weight differences obtained for the top and bottom paper towels. Assuming multiple articles are tested, average the total weight differences to obtain the Moisture Retention.  
       MULTIPLE ARTICLE EMBODIMENT  
       [0093] The articles of the present invention may also be packaged individually or with additional articles suitable for providing separate benefits not provided by the primary article, e.g., aesthetic, therapeutic, functional, or otherwise, thereby forming a personal care kit. The additional article of this personal care kit preferably comprises a water insoluble substrate comprising at least one layer and either a cleansing component containing a lathering surfactant or a therapeutic benefit component disposed onto or impregnated into that layer of the substrate of the additional article.  
       [0094] The additional article of the present invention may also serve a functional benefit in addition to or in lieu of a therapeutic or aesthetic benefit. For instance, the additional article may be useful as a drying implement suitable for use to aid in the removal of water from the skin or hair upon completion of a showering or bathing experience.  
       MULTIPLE CHAMBERED EMBODIMENT  
       [0095] The articles of the present invention may also comprise one or more chambers. Such chambers or compartments result from the connection (e.g., bonding) of the substrate layers to one another at various loci to define enclosed areas. These chambers are useful, e.g., for separating various article components from one another, e.g., the surfactant-containing cleansing component from a conditioning agent. The separated article components which provide a therapeutic or aesthetic or cleansing benefit may be released from the chambers in a variety of ways including, but not limited to, solubilization, emulsification, mechanical transfer, puncturing, popping, bursting, squeezing of the chamber or even peeling away a substrate layer which composes a portion of the chamber.  
       OPTIONAL COMPONENTS  
       [0096] The articles of the present invention may contain a variety of other components such as are conventionally used in a given product type provided that they do not unacceptably alter the benefits of the invention. These optional components should be suitable for application to human skin and hair, that is, when incorporated into the article they are suitable for use in contact with human skin without undue toxicity, incompatibility, instability, allergic response, and the like, within the scope of sound medical or formulator&#39;s judgment.

The articles of the present invention may include carrier components such as are known in the art. Such carriers can include one or more compatible liquid or solid filler diluents or vehicles which are suitable for application to skin or hair.  
       [0097] The articles of the present invention may optionally contain one or more of such optional components. Preferred articles optionally contain a safe and effective amount of therapeutic benefit component comprising a therapeutic benefit agent selected from the group consisting of vitamin compounds, skin treating agents, anti-acne actives, anti-wrinkle actives, anti-skin atrophy actives, anti-inflammatory actives, topical anesthetics, artificial tanning actives and accelerators, anti-microbial actives, anti-fungal actives, sunscreen actives, anti-oxidants, skin exfoliating agents, and combinations thereof. As used herein, “a safe and effective amount” means an amount of a compound or component sufficient to significantly induce a positive effect or benefit, but low enough to avoid serious side effects, (e.g., undue toxicity or allergic reaction), i.e., to provide a reasonable benefit to risk ratio, within the scope of sound medical judgment.  
       [0098] The optional components useful herein can be categorized by their therapeutic or aesthetic benefit or their postulated mode of action. However, it is to be understood that the optional components useful herein can in some instances provide more than one therapeutic or aesthetic benefit or operate via more than one mode of action. Therefore, classifications herein are made for the sake of convenience and are not intended to limit the component to that particular application or applications listed. Also, when applicable, the pharmaceutically-acceptable salts of the components are useful herein.

       Hydrogel Forming Polymeric Gelling Agents  
       [0120] In certain embodiments of the present invention, the articles may optionally comprise an aqueous gel, i.e., a “hydrogel”, formed from a hydrogel forming polymeric gelling agent and water. More specifically, the hydrogel is contained within the cleansing component or the therapeutic benefit component of the article. When an aqueous gel is present, the articles preferably comprise from about 0.1% to about 100%, by weight of the water insoluble substrate, more preferably from about 3% to about 50%, and most preferably from about 5% to about 35%, of a hydrogel forming polymeric gelling agent, calculated based on the dry weight of the hydrogel forming polymeric gelling agent.  
       [0121] In general, the hydrogel forming polymeric gelling agent materials of the present invention are at least partially crosslinked polymers prepared from polymerizable, unsaturated acid-containing monomers which are water-soluble or become water-soluble upon hydrolysis. These include monoethylenically unsaturated compounds having at least one hydrophilic radical, including (but not limited to) olefinically unsaturated acids and anhydrides which contain at least one carbon-carbon olefinic double bond. With respect to these monomers, water-soluble means that the monomer is soluble in deionized water at 25° C. at a level of at least 0.2%, preferably at least 1.0%.  
       [0122] Upon polymerization, monomeric units as described above will generally constitute from about 25 mole percent to 99.99 mole percent, more preferably from about 50 mole percent to 99.99 mole percent, most preferably at least about 75 mole percent of the polymeric gelling agent material (dry polymer weight basis), of acid-containing monomers.  
       [0123] The hydrogel forming polymeric gelling agent herein is partially crosslinked to a sufficient degree preferably that is high enough such that the resulting polymer does not exhibit a glass transition temperature (Tg) below about 140° C., and accordingly, the term “hydrogel forming polymeric gelling agent,” as used herein, shall mean polymers meeting this parameter. Preferably the hydrogel forming polymeric gelling agent does not have a Tg below about 180° C., and more preferably does not have a Tg prior to decomposition of the polymer, at temperatures of about 300° C. or higher. The Tg can be determined by differential scanning calorimetry (DSC) conducted at a heating rate of 20.0 C.°/minute with 5 mg or smaller samples. The Tg is calculated as the midpoint between the onset and endset of heat flow change corresponding to the glass transition on the DSC heat capacity heating curve. The use of DSC to determine Tg is well known in the art, and is described by B. Cassel and M. P. DiVito in “Use of DSC To Obtain Accurate Thermodynamic and Kinetic Data”, American Laboratory, January 1994, pp 14-19, and by B. Wunderlich in  Thermal Analysis,  Academic Press, Inc., 1990.

Preferred hydrogel forming polymeric gelling agent hereof will be able to absorb at least about 40 g water (deionized) per gram of gelling agent, preferably at least about 60 g/g, more preferably at least about 80 g/g. These values, referred to as “Absorptive Capacity” herein can be determined according to the procedure in the Absorptive Capacity “Tea Bag” test described above.

Suitable cross-linking agents having at least two functional groups reactive with the acid-containing monomer material include glyoxal; polyols such as ethylene glycol and glycerol; polyamines such as alkylene diamines (e.g., ethylene diamine), polyalkylene polyamines, polyepoxides, di- or polyglycidyl ethers and the like. Suitable polyvalent metal cross-linking agents which can form ionic cross-linkages include oxides, hydroxides and weak acid salts (e.g., carbonate, acetate and the like) of alkaline earth metals (e.g., calcium, magnesium) and zinc, including, for example, calcium oxide and zinc diacetate.  
       [0128] Cross-linking agents of many of the foregoing types are described in greater detail in Masuda et al., U.S. Pat. No. 4,076,663, issued Feb. 28, 1978, and Allen et al., U.S. Pat. No. 4,861,539, issued Aug. 29, 1989, both incorporated herein by reference. Preferred cross-linking agents include the di- or polyesters of unsaturated mono- or polycarboxylic acids mono-allyl esters of polyols, the bisacrylamides, and the di- or tri-allyl amines. Specific examples of especially preferred cross-linking agents include N,N′-methylenebisacrylamide and trimethylol propane triacrylate.  
       [0129] The cross-linking agent will generally constitute from about 0.001 mole percent to 5 mole percent of the resulting hydrogel-forming polymeric material. More generally, the cross-linking agent will constitute from about 0.01 mole percent to 3 mole percent of the hydrogel-forming polymeric gelling agent used herein.  
       [0130] The hydrogel forming polymeric gelling hereof may be employed in their partially neutralized form. For purposes of this invention, such materials are considered partially neutralized when at least 25 mole percent, and preferably at least 50 mole percent of monomers used to form the polymer are acid group-containing monomers which have been neutralized with a base. Suitable neutralizing bases cations include hydroxides of alkali and alkaline earth metal (e.g. KOH, NaOH), ammonium, substituted ammonium, and amines such as amino alcohols (e.g., 2-amino-2-methyl-1,3-propanediol, diethanolamine, and 2-amino-2-methyl-1-propanol. This percentage of the total monomers utilized which are neutralized acid group-containing monomers is referred to herein as the “degree of neutralization.” The degree of neutralization will preferably not exceed 98%.

       Hydrophobic Conditioning Agents  
       [0147] The articles of the present invention may comprise one or more hydrophobic conditioning agents which are useful for providing a conditioning benefit to the skin or hair during the use of the article. The articles of present invention preferably comprise from about 0.5% to about 1,000%, more preferably from about 1% to about 200%, and most preferably from about 25% to about 100%, by weight of the water insoluble substrate, of a hydrophobic conditioning agent.  
       [0148] The hydrophobic conditioning agent may be selected from one or more hydrophobic conditioning agents such that the weighted arithmetic mean solubility parameter of the hydrophobic conditioning agent is less than or equal to 10.5. It is recognized, based on this mathematical definition of solubility parameters, that it is possible, for example, to achieve the required weighted arithmetic mean solubility parameter, i.e., less than or equal to 10.5, for a hydrophobic conditioning agent comprising two or more compounds if one of the compounds has an individual solubility parameter greater than 10.5.  
       [0149] Solubility parameters are well known to the formulation chemist of ordinary skill in the art and are routinely used as a guide for determining compatibility&#39;s and solubilities of materials in the formulation process.  
       [0150] The solubility parameter of a chemical compound, δ, is defined as the square root of the cohesive energy density for that compound. Typically, a solubility parameter for a compound is calculated from tabulated values of the additive group contributions for the heat of vaporization and molar volume of the components of that compound, using the following equation:  
       δ   =       [         ∑   i          E   i           ∑   i          m   i         ]       1   /   2                     
 
       [0151] wherein Σ i Σ i = the sum of the heat of vaporization additive group contributions, and  
       [0152] Σ i m i = the sum of the molar volume additive group contributions  
       [0153] Standard tabulations of heat of vaporization and molar volume additive group contributions for a wide variety of atoms and groups of atoms are collected in Barton, A.F.M.  Handbook of Solubility Parameters,  CRC Press, Chapter 6, Table 3, pp. 64-66 (1985), which is incorporated by reference herein in its entirety. The above solubility parameter equation is described in Fedors, R. F., “A Method for Estimating Both the Solubility Parameters and Molar Volumes of Liquids”,  Polymer Engineering and Science,  vol. 14, no. 2, pp. 147-154 (February 1974), which is incorporated by reference herein in its entirety.  
       [0154] Solubility parameters obey the law of mixtures such that the solubility parameter for a mixture of materials is given by the weighted arithmetic mean (i.e. the weighted average) of the solubility parameters for each component of that mixture. See  Handbook of Chemistry and Physics,  57th edition, CRC Press, p. C-726 (1976-1977), which is incorporated by reference herein in its entirety.  
       [0155] Formulation chemists typically report and use solubility parameters in units of (cal/cm 3 ) ½ . The tabulated values of additive group contributions for heat of vaporization in the  Handbook of Solubility Parameters  are reported in units of kJ/mol. However, these tabulated heat of vaporization values are readily converted to cal/mol using the following well-known relationships: 
       1 J/mol=0.239006 cal/mol and 1000 J=1 kJ.

       [0157] Solubility parameters have also been tabulated for a wide variety of chemical materials.

       [0169] When the therapeutic benefit component comprises such conditioning agents, the benefit component may be made to include a variety of forms in addition to the coacervate that is formed when the article is exposed to water. In one embodiment of the present invention, the conditioning agents are in the form of an emulsion. For instance, oil-in-water, water-in-oil, water-in-oil-in-water, and oil-in-water-in-silicone emulsions are useful herein. As used in the context of emulsions, “water” may refer not only to water but also water soluble or water miscible agents like glycerin.  
       [0170] In one embodiment, the conditioning agents comprise an emulsion which further comprises an aqueous phase and an oil phase. As will be understood by the skilled artisan, a given component will distribute primarily into either the aqueous or oil phase, depending on the water solubility/dispersibility of the therapeutic benefit agent in the component. In one embodiment, the oil phase comprises one or more hydrophobic conditioning agents. In another embodiment, the aqueous phase comprises one or more hydrophilic conditioning agents.  
       [0171] When the conditioning agents of the therapeutic benefit are emulsion form, the emulsion generally contains an aqueous phase and an oil or lipid phase. Suitable oils or lipids may be derived from animals, plants, or petroleum and may be natural or synthetic (i.e., man-made). Such oils are discussed above in the Hydrophobic Conditioning Agents section. Additionally, preferred emulsions also contain a hydrophilic conditioning agent such as glycerin such that a glycerin-in-oil emulsion results.  
       [0172] Therapeutic benefit component which contains an emulsion will preferably further contain from about 1% to about 10%, more preferably from about 2% to about 5%, of an emulsifier, based on the weight of therapeutic benefit component. Emulsifiers may be nonionic, anionic or cationic. Suitable emulsifiers are disclosed in, for example, U.S. Pat. No. 3,755,560, issued Aug. 28, 1973, Dickert et al.; U.S. Pat. No. 4,421,769, issued Dec. 20, 1983, Dixon et al.; and  McCutcheon&#39;s Detergents and Emulsifiers,  North American Edition, pages 317-324 (1986). Therapeutic benefit components in emulsion form may also contain an anti-foaming agent to minimize foaming upon application to the skin. Anti-foaming agents include high molecular weight silicones and other materials well known in the art for such use.  
       [0173] The therapeutic benefit component may also be in the form of a microemulsion. As used herein, “microemulsion” refers to thermodynamic stable mixtures of two immiscible solvents (one apolar and the other polar) stabilized by an amphiphilic molecule, a surfactant. Preferred microemulsions include water-in-oil microemulsions.  
       Cleansing Component  
       [0174] The articles of the present invention may optionally comprise a cleansing component which further comprises one or more surfactants. The cleansing component is disposed adjacent to the nonwoven layer of the water insoluble substrate. The articles of the present invention comprise from about 10% to about 1,000%, preferably from about 50% to about 600%, and more preferably from about 100% to about 250%, based on the weight of the water insoluble substrate, of the surfactant. Also, the articles of the present invention preferably comprise at least about 1 gram, by weight of the water insoluble substrate, of a surfactant. Thus, the cleansing component may be added to the substrate without requiring a drying process.  
       [0175] The surfactants of the cleansing component are preferably lathering surfactants. As used herein, “lathering surfactant” means a surfactant, which when combined with water and mechanically agitated generates a foam or lather. Such surfactants are preferred since increased lather is important to consumers as an indication of cleansing effectiveness. In certain embodiments, the surfactants or combinations of surfactants are mild. As used herein, “mild” means that the surfactants as well as to the articles of the present invention demonstrate skin mildness at least milder than common bar soap matrices which typically comprise a combination of natural soap and synthetic surfactant (e.g., Lever 2000® and Zest®. Methods for measuring mildness, or inversely the irritancy, of surfactant containing articles, are based on a skin barrier destruction test. In this test, the milder the surfactant, the lesser the skin barrier is destroyed. Skin barrier destruction is measured by the relative amount of radio-labeled (tritium labeled) water (3H-H 2 O) which passes from the test solution through the skin epidermis into the physiological buffer contained in the diffusate chamber. This test is described by T. J. Franz in the  J. Invest. Dermatol.,  1975, 64, pp. 190-195; and in U.S. Pat. No. 4,673,525, to Small et al., issued Jun. 16, 1987, which are both incorporated by reference herein in their entirety. Other testing methodologies for determining surfactant mildness well known to one skilled in the art can also be used.

The acyl isethionates typically have the formula R1CO—O—CH2CH2SO3M wherein R1 is a saturated or unsaturated, branched or unbranched alkyl group having from about 10 to about 30 carbon atoms, and M is a cation. These are typically formed by the reaction of fatty acids (having from about 8 to about 30 carbon atoms) with an alkali metal isethionate. Nonlimiting examples of these acyl isethionates include ammonium cocoyl isethionate, sodium cocoyl isethionate, sodium lauroyl isethionate, and mixtures thereof.  
       [0187] Still other suitable anionic surfactants are the alkylglyceryl ether sulfonates of the form R1-OCH2-C(OH)H—CH2-SO3M, wherein R1 is a saturated or unsaturated, branched or unbranched alkyl group from about 8 to about 24 carbon atoms, and M is a water-soluble cation such as ammonium, sodium, potassium, magnesium, triethanolamine, diethanolamine and monoethanolamine.

       Additional Layers  
       [0242] In another embodiment, the article of the present invention may comprise one or more additional layers which one having ordinary skill in the art would recognize as separate and distinct from nonwoven layer yet which are attached to the nonwoven layer at some point. The additional layers are suitable for enhancing the overall grippability of the side of the article closest to the hand or other means for exerting mechanical action on the surface to be cleansed. Also, the additional layers are suitable for enhancing the soft feel of the side of the article which contacts the area to be cleansed. In any instance, these additional layers may also be referred to as consecutively numbered layers in addition to the two essential layers of the articles of the present invention, e.g., third layer, fourth layer, etc.  
       [0243] Suitable additional layers may be macroscopically expanded. As used herein, “macroscopically expanded, refers to webs, ribbons, and films which have been caused to conform to the surface of a three-dimensional forming structure so that both surfaces thereof exhibit a three-dimensional forming pattern of surface aberrations corresponding to the macroscopic cross-section of the forming structure, wherein the surface aberrations comprising the pattern are individually discernible to the normal naked eye (i.e., normal naked eye having 20/20 vision) when the perpendicular distance between the viewer&#39;s eye and the plane of the web is about 12 inches.  
       [0244] As used herein, “embossed” it is meant that the forming structure of the material exhibits a pattern comprised primarily of male projections. On the other hand, “debossed” refers to when the forming structure of the material exhibits a pattern comprised primarily of female capillary networks.  
       [0245] Preferred macroscopically expanded films comprise formed films which are structural elastic-like films. These films are described in U.S. Pat. No. 5,554,145, issued Sep. 10, 1996, to Roe et al., which is incorporated by reference herein in its entirety.  
       [0246] Materials suitable for use in the additional layer having a thickness of at least one millimeter include, but are not limited to, those web materials disclosed in U.S. Pat. No. 5,518,801, issued to Chappell et al. on May 21, 1996, which is incorporated by reference herein in its entirety.  
       METHODS OF MANUFACTURE  
       [0247] The personal care articles of the present invention are manufactured by adding the therapeutic benefit component to the appropriate sheet of the layer via a conventional method which may include, but is not limited to, sprinkling, dip coating, spraying, slot coating, and roll transfer (e.g., pressure roll or kiss roll). The sheet of the remaining layer is then placed on the sheet of the first layer, preferably, but not always, over the therapeutic benefit component. The sheets are sealed together by a conventional sealing method which may include, but is not limited to, heat, pressure, glue, ultrasound, etc. Heat sealing devices vary in design, and where a seal may not be able to be effected an interposing layer of a low-melting heat-sealable fibrous web such as the polyamide fibrous web known as Wonder Under (manufactured by Pellon, available from H. Levinson &amp; Co., Chicago, Ill.) may be used between layers for this and other examples without changing the effect or utility of the articles. The sealed sheets are then partitioned into units for the consumer&#39;s use. Optional manufacturing steps may include calendaring to flatten the article, drying, creping, shrinking, stretching, or otherwise mechanically deforming.  
       METHODS OF CLEANSING AND DELIVERING A THERAPEUTIC OR AESTHETIC BENEFIT AGENT TO THE SKIN OR HAIR  
       [0248] The present invention also relates to a method of cleansing the skin and/or hair with a personal care article of the present invention. These methods comprise the steps of: a) wetting with a substantially dry, disposable personal care article, said article comprising a water insoluble substrate comprising a nonwoven layer; and a therapeutic benefit component, disposed adjacent to said water insoluble substrate, wherein said component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a therapeutic benefit composition comprising a safe and effective amount of a cationic polymer exhibiting a Relative Hydrophobic Contribution of from about 0.2 to about 1.0 and a safe and effective amount of an anionic surfactant, wherein said composition forms a coacervate when the article is exposed to water and b) contacting the skin or hair with the wetted article.  
       [0249] The articles of the present invention are water-activated and are therefore intended to be wetted with water prior to use. As used herein, “water-activated” means that the present invention is presented to the consumer in dry form to be used after wetting with water. It is found that when the articles of the present invention include a lathering surfactant they produce a lather or are “activated” upon contact with water and further agitation. Accordingly, the article is wetted by immersion in water or by placing it under a stream of water. When the articles of the present invention comprise a lathering surfactant, lather may be generated from the article by mechanically agitating and/or deforming the article either prior to or during contact of the article with the skin or hair. The resulting lather is useful for cleansing the skin or hair. During the cleansing process and subsequent rinsing with water, any therapeutic or aesthetic benefit agents are deposited onto the skin or hair. Deposition of the therapeutic or aesthetic benefit agents are enhanced by the physical contact of the substrate with the skin or hair as well by the inclusion of one or more deposition aids.

     Prepare a representative skin cleansing article in the following manner.  
     [0265] Four grams of the cleansing component of Example 2 is applied to one side of a permeable, fusible web comprised of low-melting heat-sealable polyamide fibers. The permeable web is Wonder Under manufactured by Pellon, available from H. Levinson &amp; Co., Chicago, Ill. The cleansing component is applied to an oval area approximately 13 cm by 18 cm. The cleansing component is air dried. A layer of 2 oz/sq yd polyester batting cut to the same size as the web is placed over the fusible web. The polyester batting has a basis weight of 2 oz/yd 2  and is comprised of a blend of fibers of about 23 microns and 40 microns average diameter, at least some of which are crimped. The thickness of the batting is about 0.23 in. measured at 5 gsi. The batting is believed to be heat-bonded, utilizing no adhesive. A layer of a nonwoven is placed under the fusible web to form the second side of the article. The nonwoven is a spunlace blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is hydroapertured to form holes about 2 mm in diameter and having a basis weight of about 70 gsm. The shape of the article is about 122 mm×160 mm oval. The layers are sealed together using point bonds in a grid pattern with a heat sealing die utilizing a pressure-platen heat sealing device such as a Sentinel Model 808 heat sealer available from Sencorp, Hyannis, Mass. The point bonds measure about 4 mm diameter each and there are about 51 individual sealing points evenly spaced. The article is trimmed and ready for use.  
     Example 19  
     Prepare a Representative Skin Cleansing Article in the Following Manner  
     [0266] The cleansing component of Example 2 is applied to one side of a first substrate by extruding it through a coating head continuously in four lines separated by a distance of 20 mm, 40 mm, and 20 mm respectively, measuring widthwise across the web, making a pair of parallel lines on each side of the web. The cleansing component is extruded at a rate to yield 4.4 grams of cleansing component per finished article. The substrate is a spunlace blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is hydroapertured to form holes about 2 mm in diameter and having a basis weight of about 70 gsm. A second web which is an airlaid, lofty, low density batting is continuously fed over the first substrate placing it in contact with the surfactant-containing layer. The batting comprises a blend of 30% 15 denier PET fibers, 35% 3 denier bicomponent fibers with PET core and PE sheath, and 35% 10 denier bicomponent fibers of the same core-sheath composition, and has a basis weight of about 100 grams per square meter (gsm). The webs are continuously fed to an ultrasonic sealer which seals a dot pattern comprising a grid of 4 mm diameter sealing points spaced evenly across the web. The web is cut into individual articles measuring about 120 mm×160 mm rectangles with rounded corners, which has a total of about 51 sealing points per article.

     [0271] Four grams of the cleansing component of Example 2 is spread evenly by hand across a lofty batting. The batting is an airlaid, lofty, low density batting comprising a blend of 30% 15 denier PET fibers, 35% 3 denier bicomponent fibers with PET core and PE sheath, and 35% 10 denier bicomponent fibers of the same core-sheath composition, and has a basis weight of about 100 grams per square meter (gsm). A layer of fibrous nonwoven which is a hydroentangled blend of 55% cellulose and 45% polyester having a basis weight of about 65 gsm (available as Technicloth II from The Texwipe Company, Saddle River, N.J.) is placed over the cleansing component coated side of the batting. The layers are sealed together using interlocking sealing plates using an unheated plate having inverted thimble-shaped reservoirs spaced evenly in a hexagonal grid pattern. The thimble shaped reservoirs are about 1.2 cm diameter at the base and are spaced about 2 cm apart, center-to-center. The land area between the dimples on the unheated plate is concave inwards by several mm, forming an interconnected trough. The heated plate has an external ridge which fit precisely into the trough on the land area of the unheated plate. The heated plate contacts the cellulose/polyester substrate and a heat seal is effected using pressure-platen heat sealing device such as a Sentinel Model 808 heat sealer available from Sencorp, Hyannis, Mass. The resulting unfinished article has pronounced thimble shapes rising up on the batting side, and shorter dimples or ‘buttons’ rising up on the cellulose/polyester substrate side of the article, making both sides easy to grip. The article is cut into a rectangle about 120 mm by 160 mm. Three grams of skin conditioning composition per article is pipetted into the trough area while the composition is hot, and allowed to cool and solidify. The article is packaged until ready for use.

     [0272] The liquid cleansing component of Example 3 is applied to a first substrate by dipping a 120 mm by 160 mm section of the substrate in a bath of the composition until it has increased its weight by about 8 grams. The substrate is a batting comprising a blend of 30% 15 denier PET fibers, 35% 3 denier bicomponent fibers with PET core and PE sheath, and 35% 10 denier bicomponent fibers of the same core-sheath composition, and has a basis weight of about 100 grams per square meter (gsm). The substrate is dried. A piece of a second substrate which is a spunlace blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive and hydroapertured to form holes about 2 mm in diameter, having a basis weight of about 70 gsm is placed over the first substrate. The substrates are sealed together using an ultrasonic sealer which seals a dot pattern comprising a grid of 4 mm diameter sealing points spaced evenly across the article. Four grams of skin conditioning composition is applied evenly over both sides of the article by feeding the composition through a slotted rolling device with a machined 1.5 mm gap and a feed reservoir held at about 60° C. The composition quickly cools on the article surface and is stored in a sealed, metallized film package until ready for use.

The thimble shaped reservoirs are about 1.2 cm diameter at the base and are spaced about 1.5 cm apart, center-to-center. The land area between the dimples on the unheated plate is convex upwards by several mm, forming an interconnected ridge. The heated plate has an external trough which fits precisely onto the ridge of the unheated plate. The heated plate contacts the cellulose/polyester substrate and a heat seal is effected using a pressure-platen heat sealing device such as a Sentinel Model 808 heat sealer available from Sencorp, Hyannis, Mass. The resulting unfinished article has topographical features on both sides, assisting lather generation and also making it easy to grip and slide across the skin surface during use. The article is cut into a rectangle about 120 mm by 160 mm.

Three grams of the skin conditioning inverse emulsion paste is pipetted hot into the depressed zones on the cellulose/polyester side of the article. The composition quickly cools to a semi-solid paste. The article is packaged until ready for use.  
     Example 35  
     Prepare a Representative Skin Conditioning Article in the Following Manner Using the Skin Conditioning Composition of Example 7  
     [0276] The conditioning composition is applied to one side of a first substrate by extruding it through a coating head continuously in four strips, each 5 mm wide, separated by a distance of 20 mm, 40 mm, and 20 mm respectively, measuring widthwise across the web, making a pair of parallel lines on each side of the web. The composition is extruded at a rate to yield 3 grams of composition per finished article. The substrate is a spunlace blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is hydroapertured to form holes about 2 mm in diameter and having a basis weight of about 70 gsm. A second web which is an airlaid, lofty, low density batting is continuously fed over the first substrate placing it in contact with the first substrate on the side containing no skin conditioning composition. The batting comprises a blend of 30% 15 denier PET fibers, 35% 3 denier bicomponent fibers with PET core and PE sheath, and 35% 10 denier bicomponent fibers of the same core-sheath composition, and has a basis weight of about 100 grams per square meter (gsm). The webs are continuously fed to an ultrasonic sealer which seals a dot pattern comprising a grid of 4 mm diameter sealing points spaced evenly across the web. The web is cut into individual articles measuring about 120 mm×160 mm rectangles with rounded corners, which has a total of about 51 sealing points per article.

     [0277] The conditioning composition is applied to one side of a first substrate by extruding it through a coating head continuously in four strips, each 5 mm wide, separated by a distance of 20 mm, 40 mm, and 20 mm respectively, measuring widthwise across the web, making a pair of parallel lines on each side of the web. The composition is extruded at a rate to yield 1.1 grams of composition per finished article. The substrate is a spunlace blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is hydroapertured to form holes about 2 mm in diameter and having a basis weight of about 70 gsm. A second web which is an airlaid, lofty, low density batting is continuously fed over the first substrate placing it in contact with the first substrate on the side containing no skin conditioning composition. The batting comprises a blend of 10% 15 denier PET fibers, 50% 3 denier bicomponent fibers with PET core and PE sheath, and 40% 10 denier bicomponent fibers of the same core-sheath composition, and has a basis weight of about 80 grams per square meter (gsm). The webs are continuously fed to an ultrasonic sealer which seals a dot pattern comprising a grid of 4 mm diameter sealing points spaced evenly across the web. The web is cut into individual articles measuring about 120 mm×90 mm rectangles with rounded comers, which has a total of about 51 sealing points per article. The article is convenient for application to smaller areas of skin, for example the face, elbows, neck and/or feet.

     [0278] The cleansing component of Example 2 is applied to one side of a first substrate by extruding it through a coating head continuously in four lines separated by a distance of 20 mm, 40 mm, and 20 mm respectively, measuring widthwise across the web, making a pair of parallel lines on each side of the web. The cleansing component is extruded at a rate to yield 0.52 grams of cleansing component per finished article. The substrate is a spunlace blend of 70% rayon and 30% PET fibers, bonded with a styrene-butadiene adhesive, which is hydroapertured to form holes about 2 mm in diameter and having a basis weight of about 70 gsm. A second substrate web which is an airlaid, lofty, low density batting is continuously fed over the first substrate placing it in contact with the surfactant layer. The batting comprises a blend of 10% 15 denier PET fibers, 50% 3 denier bicomponent fibers with PET core and PE sheath, and 40% 10 denier bicomponent fibers of the same core-sheath composition, and has a basis weight of about 80 grams per square meter (gsm). A third substrate web which is the same as the second substrate web is continuously fed over the second substrate web placing it in contact with the second substrate. The webs are continuously fed to an ultrasonic sealer which seals a dot pattern comprising a grid of 4 mm diameter sealing points spaced evenly across the web. Skin conditioning composition is slot coated from a hot reservoir pumped through a slot dye onto both sides of the substrate web at a rate equal to 1.25 grams of skin conditioning composition per finished article (about 55 gsm add-on per side), and passed across a cooling fan so the composition cools quickly on the article outer surfaces. The web is cut into individual articles measuring about 120 mm×90 mm rectangles with rounded comers.
