WO 01/08658 PCT/USOO/20916 1 PERSONAL CARE ARTICLES TECHNICAL FIELD 5 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 comprise a water insoluble substrate having a nonwoven first layer and a second layer disposed adjacent to the first layer; and a cleansing component disposed adjacent to the first layer, wherein the cleansing component comprises from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering 10 surfactant and wherein the article exhibits the following surfactant dissolution related physical properties individually or in combination with one another. The properties exhibited include a Dynamic Surface Tension Value of less than about 54 dynes/ cm 2 in beaker 1 and greater than about 60 dynes/ cm 2 in beaker 5, a Flash Lather Volume of from about 500 ml to about 3500 ml, a Latherability of from about 500 ml to about 7000 ml, a Lather Dissipation Time of from about 5 sec to about 62 sec, and a Surfactant Dissolution 15 Extent of greater than about 30 ml in beaker 1, greater than about 30 ml in beaker 4 and less than about 90 ml in beaker 8. Consumers use the articles by wetting them with water and rubbing on the area to be cleansed and/or therapeutically treated (e.g., conditioned). The invention also encompasses methods for cleansing and conditioning the skin and hair using the articles of the present invention. 20 BACKGROUND OF THE INVENTION 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 25 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. 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 30 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. The articles of the present invention surprisingly provide effective cleansing and/or therapeutic 35 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 WO 01/08658 PCT/USOO/20916 2 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 5 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). 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 10 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.. In preferred embodiments of the present invention, the articles are suitable for personal care applications and are useful for cleansing and therapeutically treating the skin, hair, and similar keratinous surfaces. Consumers use these articles by wetting them with water and rubbing them on the area to be 15 cleansed and treated. The article consists of a water insoluble substrate having a first nonwoven first layer, a second layer disposed adjacent to the first layer; and a cleansing component containing a lathering surfactant wherein the article exhibits the following physical properties individually and in combination: 1) a Dynamic Surface Tension Value of less than about 54 dynes/ cm 2 in beaker 1 and greater than about 60 dynes/ cm 2 in beaker 5, 2) a Flash Lather Volume of from about 500 ml to about 3500 ml, 3) a 20 Latherability of from about 500 ml to about 7000 ml, 4) a Lather Dissipation Time of from about 5 sec to about 62 sec, and 5) a Surfactant Dissolution Extent of greater than about 30 ml in beaker 1, greater than about 30 ml in beaker 4 and less than about 90 ml in beaker 8. Without being limited by theory, the substrate enhances lathering which in turn increases cleansing and exfoliation, and optimizes delivery and deposition of a therapeutic or aesthetic benefit agent which might be contained within the article. 25 SUMMARY OF THE INVENTION The present invention relates to a substantially dry, disposable personal care article suitable for cleansing, said article comprising: a) a water insoluble substrate comprising: 1) a nonwoven first layer; 30 2) a second layer which is disposed adjacent to said first layer; b) a cleansing component disposed adjacent to said first and second layers, wherein said component comprises: 1) from about 10% to about 1000%, by weight of the water insoluble substrate, of a lathering surfactant; 35 wherein said article exhibits a Dynamic Surface Tension Value of less than about 54 dynes/ cm 2 in beaker 1 and greater than about 60 dynes/ cm2 in beaker 5.

All percentages and ratios used herein, unless otherwise indicated, are by weight and all 10 measurements made are at 25*C, unless otherwise designated. The invention hereof can comprise, consist of, or consist essentially of, the essential as well as optional ingredients and components described therein. 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. 15 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 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 20 10, and most preferably less than about 2 entire usage events. 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 25 is discussed later. The personal care articles of the present invention comprise the following essential components. WATER INSOLUBLE SUBSTRATE The articles of the present invention comprise a water insoluble substrate that further comprises at least two layers, namely a nonwoven first layer and a second layer. Preferably, the substrate layers are soft 30 yet invigorating to the skin of the consumer when used. Accordingly, the layers are "non-scouring". As used herein, "non-scouring" means that the layers preferably exhibit an Abrasiveness 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 defined by the Abrasiveness Value Methodology detailed below. In any case, however, the nonwoven first layer and second layer are each 35 defined as having both an interior and exterior surface. In both cases, the interior surfaces of the layers are those which face the inside or innermost portion of the article of the present invention whereas the exterior surfaces of the layers are those which face the outside or outermost portion of the article. Generally, the WO 01/08658 PCT/USOO/20916 5 orientation of the articles of the present invention may be defined such that the second layer is closer to the side of the article suitable for gripping (i.e., the gripping side) while the nonwoven first layer is closer to the side of the article to be contacted with the area to be cleansed and/or therapeutically treated, e.g. the skin/site contact side. Both sides of the article, however, are suitable for contact with the skin. 5 Without being limited by theory, it is believed that 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. 10 In preferred embodiments, however, the substrate is non-scouring or nonabrasive to the skin. NONWOVEN FIRST LAYER The water insoluble substrate of the present invention further comprises a nonwoven first layer. This nonwoven first layer is preferably fluid-permeable. This nonwoven first layer is useful for engaging or retaining the cleansing component within the article. Furthermore, the nonwoven first layer may also be 15 suitable for contact with the skin in which case it is preferred that the layer is soft to the skin. Materials suitable for the nonwoven layer are selected from the group consisting of cellulosic nonwovens, non-lofty nonwovens, sponges (i.e., both natural and synthetic), formed films, non-lofty battings, and combinations thereof. Preferably, the nonwoven layer comprises materials selected from the group consisting of cellulosic nonwovens, non-lofty nonwovens, formed films, non-lofty battings, foams, 20 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, non-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 25 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 nonwoven layer can be a composite material composed of a combination of additional layers, i.e., plies, of random and carded fibers. In a preferred embodiment, the nonwoven first layer is apertured. The apertures in the nonwoven first layer of the water insoluble substrate will generally range in average diameter between about 0.5 mm 30 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 first layer of the substrate will fall outside these size ranges. More preferably, no more than about 5% of the apertures in the nonwoven first 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 35 opening of the non-circular shaped aperture.

WO 01/08658 PCT/USOO/20916 6 Within the nonwoven first 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 cleansing surface will occur at a frequency of from about 1.5 to 6 apertures per straight linear centimeter. The apertures must at least be placed within the nonwoven first layer. Such apertures need not 5 protrude completely through one surface of the nonwoven first layer to the other. They, however, may do so. Additionally, apertures may or may not be placed in the additional layers of the substrate such that the article is apertured through it's entire volume. Apertures may be formed in the nonwoven first 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 10 nonwoven first layer after the substrate comprising the layer has been completely formed. The nonwoven first 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. 15 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 20 preferred in the present invention. 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 25 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 terephthalate 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 30 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. Patent No. 4,891,227, to Thaman et al., issued January 2, 1990; and U. S. Patent No. 4,891,228, each of which is incorporated by reference herein in its entirety. A preferred nonwoven first layer comprises batting which comprises synthetic fibers. Preferred 35 synthetic 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 WO 01/08658 PCT/USOO/20916 7 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 5 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 10 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 15 materials. For the core-sheath fibers, preferably, the cores comprise materials selected from the group consisting of polyesters, polyolefins having a Tg 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 Tg of at least about 10*C lower than the core 20 material, polyesters polyolefins having a Tg of at least about 10 0 C lower than the core material, and combinations thereof. In any instance, side-by side configuration, core-sheath configuration, or solid single component configuration, the fibers of the nonwoven first layer may exhibit a helical or spiral or crimped configuration, particularly the bicomponent type fibers. 25 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. Smook, Handbook of Pulp and Paper Technologies, Technical Association for the Pulp and Paper Industry (1986); which are incorporated by reference herein in their entirety. 30 Natural material nonwovens useful in the present invention may be obtained from a wide variety of commercial sources. Nonlimiting examples of suitable commercially available paper layers useful herein include Airtex@, an embossed airlaid cellulosic layer having a base weight of about 71 gsy, available from James River, Green Bay, WI; and Walkisoft@, an embossed airlaid cellulosic having a base weight of about 75 gsy, available from Walkisoft U.S.A., Mount Holly, NC. 35 Additional suitable nonwoven materials include, but are not limited to, those disclosed in U. S. Patent Nos. 4,447,294, issued to Osborn on May 8, 1984; 4,603,176 issued to Bjorkquist on July 29, 1986; 4,981,557 issued to Bjorkquist on January 1, 1991; 5,085,736 issued to Bjorkquist on February 4, 1992; WO 01/08658 PCT/USOO/20916 8 5,138,002 issued to Bjorkquist on August 8, 1992; 5,262,007 issued to Phan et al. on November 16, 1993; 5,264,082, issued to Phan et al. on November 23, 1993; 4,637,859 issued to Trokhan on January 20, 1987; 4,529,480 issued to Trokhan on July 16, 1985; 4,687,153 issued to McNeil on August 18, 1987; 5,223,096 issued to Phan et al. on June 29, 1993 and 5,679,222, issued to Rasch et al. on October 21, 1997, each of 5 which is incorporated by reference herein in its entirety. 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, 10 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 first layer can be prepared by a variety of processes including, but not limited to, air-entanglement, hydroentanglement, thermal bonding, and combinations of these processes. Nonwoven substrates made from synthetic materials useful in the present invention can be obtained 15 from a wide variety of commercial sources. Nonlimiting examples of suitable nonwoven first layer materials useful herein include HEF 40-047, an apertured hydroentangled material containing about 50% rayon and 50% polyester, and having a basis weight of about 61 grams per square meter (gsm), available from Veratec, Inc., Walpole, MA; HEF 140-102, an apertured hydroentangled material containing about 50% rayon and 50% polyester, and having a basis weight of about 67 gsm, available from Veratec, Inc., 20 Walpole, MA; Novonet® 149-616, a thermo-bonded grid patterned material containing about 100% polypropylene, and having a basis weight of about 60 gsm available from Veratec, Inc., Walpole, MA; Novonet® 149-801, a thermo-bonded grid patterned material containing about 69% rayon, about 25% polypropylene, and about 6% cotton, and having a basis weight of about 90 gsm, available from Veratec, Inc.

Walpole, MA; HEF Nubtex® 149-801, a nubbed, apertured hydroentangled material, containing about 100% polyester, and having a basis weight of about 84 gsm , available from Veratec, Inc. Walpole, MA; Keybak® 95 IV, a dry formed apertured material, containing about 75% rayon, about 25% acrylic fibers, and having a basis weight of about 51 gsm, available from Chicopee, New 30 Brunswick, NJ; Keybak® 1368, an apertured material, containing about 75% rayon, about 25% polyester, and having a basis weight of about 47 gsm, available from Chicopee, New Brunswick, NJ; Duralace® 1236, an apertured, hydroentangled material, containing about 100% rayon, and having a basis weight from about 48 gsm to about 138 gsm, available from Chicopee, New Brunswick, NJ; Duralace® 5904, an apertured, hydroentangled material, containing about 100% polyester, and having a basis weight from about 48 gsm to 35 about 138 gsm, available from Chicopee, New Brunswick, NJ; Chicopee® 5763, a carded hydroapertured material (8x6 apertures per inch, 3X2 apertures per cm), containing about 70% rayon, about 30% polyester, WO 01/08658 PCT/USOO/20916 9 and a optionally a latex binder (Acrylate or EVA based) of up to about 5% w/w, and having a basis weight from about 60 gsm to about 90 gsm , available form Chicopee, New Brunswick, NJ; Chicopee® 9900 series (e.g., Chicopee 9931, 62 gsm, 50/50 rayon/polyester, and Chicopee 9950 50 gsm, 50/50 rayon/polyester), a carded, hydroentangled material, containing a fiber composition of from 50% rayon/50% polyester to 0% 5 rayon/100% polyester or 100% rayon/0% polyester, and having a basis weight of from about 36 gsm to about 84 gsm, available form Chicopee, New Brunswick, NJ; Sontara 8868, a hydroentangled material, containing about 50% cellulose and about 50% polyester, and having a basis weight of about 72 gsm, available from Dupont Chemical Corp. 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 10 preferably from about 42 gsm to about 78 gsm. The nonwoven first layer may also be a polymeric mesh sponge as described in European Patent Application No. EP 702550A1 published March 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 nylon or a strong flexible polymer, such as addition polymers of olefin monomers and 15 polyamides of polycarboxylic acids. The nonwoven first layer may also comprise formed films and composite materials, i.e., multiple 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 first layer comprises a plastic formed film, it is 20 preferred that the nonwoven first layer be apertured, e.g., macroapertured or microapertured, such that the layer is fluid permeable. In one embodiment, the nonwoven first 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/ therapeutic benefit component. In certain embodiments 25 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/ 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/therapeutic benefit component 30 contained within the article thereby extending the article's useful life. In another embodiment, the nonwoven first layer comprises a plastic formed film which is both microapertured and macroapertured. In such embodiments, the nonwoven first layer is well-suited to contact the area to be cleansed and/or therapeutically treated given the cloth-like feel of such microapertured films. Preferably, in such an embodiment, the surface aberrations of the microapertures face opposite of the 35 surface aberrations of the macroapertures on the nonwoven first layer. In such an instance, it is believed that the macroapertures maximize the overall wetting/lathering of the article by the three-dimensional thickness WO 01/08658 PCT/USOO/20916 10 formed from the surface aberrations which are under constant compression and decompression during the use of the article thereby creating lathering bellows. In any case, the nonwoven first layer comprising a formed film preferably has at least about 100 apertures/cm2, more preferably at least 500 apertures/cm 2, even still more preferably at least about 1000 5 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 first layer which has water flux rate of from about 5 cm 3 /cm 2 -s to about 70 cm3/cm2-s, more preferably from about 10 cm 3 /cm 2 -s to about 50 cm3/cm 2 -s and most preferably from about 15 cm 3/cm2-s to about 40 cm3/cm2-s. Suitable formed films and formed film-containing composite materials useful in the nonwoven first 10 layer of the present invention include, but are not limited to, those disclosed in U. S. Patent No. 4,342,314 issued to Radel et al. on August 3, 1982, commonly assigned co-pending application U. S. Serial No. 08/326,571 and PCT Application No. US95/07435, filed June 12, 1995 and published January 11, 1996, and U. S. Patent No. 4,629,643, issued to Curro et al. on December 16, 1986, each of which is incorporated by reference herein in its entirety. Furthermore, the nonwoven first layer may be a formed film composite 15 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. Additionally, the nonwoven first layer and the second layer (as well as any additional layers) are 20 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.) or in a discontinuous pattern, or by bonding at the external edges (or periphery) of the layers and/or at discrete loci or combinations thereof. The bonding may also 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. 25 It is also envisioned in the articles of the present invention that the first 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. In any event, it is preferred that the bonded area present between the nonwoven first layer and 30 second layer 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%. 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. 35 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 WO 01/08658 PCT/USOO/20916 11 abrasive side for exfoliation and a softer, absorbent side for gentle cleansing and/or 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. Furthermore, each of the layers of the articles as well as the articles themselves may be made into a 5 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 10 200 in 2 , preferably from about 6 in 2 to about 120 in 2 , and more preferably from about 15 in 2 to about 100 in 2 , 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. SECOND LAYER The articles of the present invention further comprise a second layer. The second layer comprises 15 materials selected from the group consisting of nonwovens, wovens, sponges, and combinations thereof. This second layer is useful for providing a different texture side to the article of the present invention as well as acting as an additional carrier for the cleansing component and/or therapeutic benefit component. Nonwovens suitable for use in the second layer include but are not limited to those discussed above in the Nonwoven First Layer section. In addition, suitable wovens include, but are not limited to, polymeric 20 nets (scrims). Srims comprise fibers such as those mentioned as suitable for the nonwoven first layer. In a preferred embodiment the second layer comprises a woven comprising a synthetic material comprising nylon fibers. A more preferred synthetic material comprises nylon fibers formed into a scrim layer having additional nylon fibers bonded thereto such that the additional fibers form arcs on the scrim layer. 25 Properties of the Layers Abrasiveness Value Methodology The Abrasiveness Value indicates the "non-scouring" property of the nonwoven first layer of the present articles. The nonwoven first layer 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 30 surface using a mechanical device and then examining the resulting scratch marks produced on the test surface using different analysis techniques. The following equipment is needed for the methodology. 1. Martindale Toothbrush Wear and Abrasion Tester: Model 103, serial nos. 103-1386/2 upwards. Martindale 07-01-88 made by James H. Heal and Co. Ltd. Textile Testing and QC Equipment. Foot 35 area: 43x44mm. 1Kg weight. 2. Capped Polystyrene strips 11x8cm. Clear general purpose polystyrene layer on white High Impact Polystyrene, e. g., EMA Model Supplies SS-20201L.

WO 01/08658 PCT/USOO/20916 12 3. Substrates to be tested. 4. Glossmeter, e.g. Sheen Tri-Microgloss 20-60-85 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 5 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" x 2.5" substrate sample. Attach the substrate sample to the scrubbing foot of the Martindale wear tester, 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 10 screws supplied. Slot 1Kg 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 wear tester with a safety screen. Set the machine to perform 50 cycles in 1 minute and allow to run. (Frequency = 0.833Hz). 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. 15 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 the scratched side of the polystyrene strip. A 200 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. 20 CLEANSING COMPONENT The articles of the present invention comprise a cleansing component which further comprises one or more surfactants. The cleansing component is disposed adjacent to the water insoluble substrate. In certain embodiments, the cleansing component is impregnated into the water insoluble substrate. In another embodiment, the cleansing component is deposited onto either or both surfaces of the water insoluble 25 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. 30 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 35 present invention demonstrate skin mildness comparable to a mild alkyl glyceryl ether sulfonate (AGS) surfactant based synthetic bar, i.e., synbar. 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 WO 01/08658 PCT/USOO/20916 13 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 0) 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. Patent No. 4,673,525, to Small et 5 al., issued June 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. A wide variety of lathering surfactants are useful herein and include those selected from the group consisting of anionic lathering surfactants, nonionic lathering surfactants, cationic lathering surfactants, amphoteric lathering surfactants, and mixtures thereof. 10 Anionic Lathering Surfactants Nonlimiting examples of anionic lathering surfactants useful in the compositions of the present invention are disclosed in McCutcheon's, Detergents and Emulsifiers, North American edition (1986), published by Allured Publishing Corporation; McCutcheon's, Functional Materials, North American Edition (1992); and U.

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 35 of the compounds has an individual solubility parameter greater than 10.5.

WO 01/08658 PCT/USOO/20916 21 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's and solubilities of materials in the formulation process. The solubility parameter of a chemical compound, 6, is defined as the square root of the cohesive 5 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: 1/2 XE mi 10 wherein I Ei = the sum of the heat of vaporization additive group contributions, and X m = the sum of the molar volume additive group contributions Standard tabulations of heat of vaporization and molar volume additive group contributions for a wide 15 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. 20 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. Se, Handbook of Chemistry and Physics, 57th edition, CRC Press, p. C-726 (1976-1977), which is incorporated by reference herein in its entirety. Formulation chemists typically report and use solubility parameters in units of (cal/cm 3 )1/ 2 . The 25 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 IJ.

Dynamic Surface Tension Value Methodology The Dynamic Surface Tension Value measures the amount of surfactant that is released from the 15 article upon water submersion. Obtain a Sensadyne 9000 Surface Tensiometer (serial no. 0358, 4mm large glass probe, 0.5 small glass probe) (or an equivalent thereof). Calibrate the tensiometer using a sample of distilled water at room temperature and a sample of ethyl alcohol a room temperature. Insert the glass probes into the distilled water sample and have tensiometer analyze the sample. Observe the surface tension value and as soon as it 20 is stable, calibrate that value as the high surface tension. Repeat calibration for the ethyl alcohol sample and calibrate it's surface tension as the low surface tension. Using water set at 5 gpg and 37 'C ± 2'C, measure the surface tension. Then, fill a 2000ml beaker with 1000 g of the prepared water. Next, hold the cleansing article loosely at the corner and submerge the entire sample into the beaker and remove the sample from the water. This dunking should be repeated 4 25 more times such that 5 dunks are completed in 10 seconds. Being careful not to squeeze or fold the sample, it is important that the entirety of the sample is submerged. After the fifth dunk, raise the sample above the beaker and allow the excess water from the sample to drain into the beaker for 15 seconds being careful not to shake the sample. Pour 140 g water from the 2000 ml beaker into a 150 ml beaker and measure the Dynamic Surface Tension Value using the tensiometer. Continue to repeat the submergence in 1000 g 30 batches of fresh water and obtain the surface tension measurement (DSTV) of each sample until the DSTV equals the initial surface tension measurement of the prepared water. Surfactant Dissolution Extent Methodology The Surfactant Dissolution Extent measures the rate at which the surfactant contained within the article is released when exposed to water, i.e., upon submergence, as is experienced in a shower or a bath. 35 Begin by filling ten 2000ml beakers with tap water (10 grains per gallon) and label them consecutively. Maintain the temperatures of the beakers in a 104'F water bath until the temperature of the water in the beakers equilibrates. Next, hold the article above beaker 1 and submerge and remove the WO 01/08658 PCT/US00/20916 30 article six times in 5 seconds and after the sixth submergence and removal allow the excess water from the article to drip into the beaker for an additional 15 seconds. Being careful not to squeeze or fold the sample, it is important that the entirety of the sample is submerged. Repeat the submergence/removal cycle/drip cycle of the article in each of the remaining beakers consecutively. 5 Upon completion of these cycles pour 25 ml of solution from each beaker into a correspondingly labeled 100 ml capped scaled cylinder. Seal each cylinder with parafilm and mount each cylinder in a rotator such that the cylinder is clamped by the rotator at the 58 ml position (or relatively near the center of the cylinder to aid in balancing the cylinder during rotation. Rotate each cylinder at a rate of 40 rpm for 1 minute. Remove each cylinder from the rotator and let each stand for 2 minutes. Measure the lather 10 volume that appears in each cylinder. The Surfactant Dissolution Extent represents the lather volume in each beaker. Flash Lather Volume, Latherability, Lather Dissipation Time Methodologies The Flash Lather Volume (FLV) is indicative of the amount of lather generated by the articles of the present invention in a matter of one minute. The Latherability measures the amount of lather generated 15 by a cleansing article under simulated shower conditions (i.e., in the presence of running water). The Lather Dissipation Time (LDT) indicates the time required for the lather to dissipate under a constant flow of water. The test is run with water with a hardness of 10 grains per gallon, a temperature of 104'F and a water flow rate of 1.0 gallon per minute. Run the water through a sprinkler head which emits 16 individual 20 streams of water within its 2 inch diameter. Place a plastic storage box measuring 23 inches length x 16 inches width x 9 inches height in a deep sink adjacent to the running water (e.g., Rubbermaid 14.7 gallon plastic Storage Box). Then elevate one end of the storage box to create an angle of about 30-45 degrees, the slope running lengthwise. Cut away one side of the storage box (along 23 in side) in a semicircular pattern leaving a wall height of only 4" at the center to allow easy access. Place a flexible bath mat with suction 25 feet, e.g., Rubbermaid Safti-Grip Bath Mat, faced down on the bottom of the storage box. The whole unit is continuously sprayed with warm water at 104 'F before actual measurement. Once unit has been wetted, stop the water flow. Place an article of the present invention comprising a surfactant containing cleansing component in the center of the bath mat. If the article is flat in design, hold its leading edge up to allow wetting of the underside. Point the water at the article for 1 second to wet it, and then spray the water at the 30 article while stroking the article in circle on the unit. Continue spraying and lathering the article for an additional 4 seconds such that water is sprayed for 5 seconds total seconds and then stop the water flow. A diverting lever to maintain flow but direct it through the shower head or towards the drain is useful. After the initial 5 seconds of wetting and lathering the article, an experimenter begins further lathering the article vigorously at a stroke rate of 2 per second, dipping the article into the water through at the bottom of the mat 35 after each stroke to maintain a fully wet article and mat. Each stroke covers the entire distance, end-to-end, of the bath mat, reaching to each edge of the box. After 30 seconds total elapsed time (5 seconds with water spraying and 25 seconds without water spraying), repeat 30 second lathering cycle again. Then, remove the WO 01/08658 PCT/USOO/20916 31 article from the tub without squeezing and place the article in a beaker. Remove the lather filled box from the sink and pour the box's contents through a cheesecloth covered colander (100% cotton, heavy duty cheesecloth, cut to about 16 inches x 23 inches). Remove all of the lather and place in a suitable beaker for lather volume measurement while a catch basin under the colander catches the water that is then weighed to 5 check the water flow rate. Carefully lift the cheesecloth out of the colander and transfer the foam to the previously filled foam containing beaker. Once all lather is transferred to the beaker, level the lather in the beaker and measure its volume. This volume is the Flash Lather Volume. Next, measure the lather weight and calculate the density of the lather using its weight and volume. Next, return the box to the sink, and repeat the above-listed steps with the previously used article. The total 10 lather volume in the two minutes of lathering is the Latherability of the article. To ensure consistency, run two standard products at least at the start and end of each (daily) group of experiments. The standard products are the articles of Comparative Examples A and B. The standard product typically produces an average of about 1250 ml of lather with a lather density of about 0.058 g/ml. The articles of the present invention preferably produce from about 500 ml to about 4000 ml in 2 15 minutes, more preferably from about 750 ml to about 3000 ml and most preferably from about 1000 ml to about 2500 ml, of lather based on the Latherability Test. Once the Latherability is determined, the Lather Dissipation Time may be determined. Transfer the entire lather volume back to the cheesecloth-covered colander and place the stableness colander (top opening: 11.5" in diameter; base circle diameter: 4.5"; 3.7" deep, 3 mm holes one inch apart, total hole 20 numbers: 120 holes distributed evenly on circular side and 37 holes distributed evenly on the bottom of the colander) in the sink. Begin timing once lather-filled colander is placed beneath the water flow (1.0 gpm at 104 *F). Rotate the colander under the water flow and stop timing as soon as lather completely disappears. The time required for lather disappearance is the Lather Dissipation Time. Loft-Soft Ratio Methodology 25 Loftiness of substrates and softness of substrates are related. Softness has several independent, contributing components. One component is a kind of "pillowy" softness. That is, when a force is applied by hand or finger pressure, the substrate easily compresses in much the same way a pillow compresses under pressure to support a body member resting thereon. This test measures parameters related to loftiness using the following pieces of equipment: 30 1. Instron Model 1122 Compression and Tensile tester (or equivalent thereof); 2. Instron Serial Number 445 (200 grams full scale) compression load cell (or equivalent thereof); 3. Flat top plate, attachable to load cell; 4. Flat base plate, under load cell; 5. 1.875 inch diameter punch; and 35 6. a hammer. Substrate samples are cut using a 1.875 inch diameter punch and hammer. In instances where the punching process inelastically compresses edges of discs, the edges are carefully fluffed to restore original WO 01/08658 PCT/USOO/20916 32 dimension. With the top plate in position, the Instron load cell is calibrated and is then run in compression mode at 0.50 inches/minute rate of descent. The Instron may be controlled manually or by computer as long as the final compression is greater than 30 grams/in 2 pressure and data is collected quickly enough (computer assisted recommended) to determine the height at various compression values during descent. 5 The top plate is then moved down until it contacts the base plate at which point the height is set at zero. It is important that the top plate and base plate are parallel, making contact at all points simultaneously. Once the apparatus is zeroed, the top plate is retracted to a position above the base plate allowing sufficient space to interpose a substrate sample disc. A substrate disc is then placed in the center of the base plate. The Instron is then set to compress each substrate sample once fully. Next, the Instron is turned on 10 and the height and force of the top plate is continuous recorded. Once the compression of the sample is complete, the compression of new samples of the same substrate is repeated as many times as is needed to establish a reliable average. The average height above the base plate at compression values of 5 gms/in2 and 30 gms/in 2 equals the thickness at 5 gms/in 2 and 30 gms/in 2 , respectively. The Loft-Soft Ratio is then calculated as the ratio of the thickness at 5 gms/in 2 divided by the thickness at 30 gms/in 2 . 15 Crepe Ratio Method Creping produces substrates that have patterns of peaks and valleys. Creping can add value to substrates by providing bulk, softness, enhanced ability to remove dirt, enhanced transport of air and water necessary for lather, compressive resiliency, and visually pleasing appearance. Individual substrates can be creped and optionally combined with other substrates, creped or uncreped; also multi-layered articles can be 20 creped. This method can be used to define amount of creping for individual substrates or finished articles. There are a number of different ways to measure the amount of creping. The objective of this method is to measure a bulky, thick dimension representative of the peak-to-nadir dimension of the substrate; and a thin dimension representative of "wall thickness" of the substrate. The first layer preferably exhibits a Crepe Ratio of from about 3 to about 45, more preferably the 25 lower Crepe Ratio limit is about 4.1, more preferably about 4.15, even more preferably about 4.2, and most preferably about 4.25. The upper limit for the Crepe Ratio is more preferably 20, even more preferably 15 and most preferably about 12. These lower and upper limits may be combined to give an optimum range. First, the thickness of the substrate to be tested is measured at a Compression Relaxation Hysteresis Value (CRHV) of 5 grams/in2 according to the Loft-Soft Method that is discussed above. Several 30 representative pieces of the same substrate are then cut measuring a few square inches. Next, the Flat End Knife Probe (0.02 inches thick X 7mm wide) is attached to the top of an Instron Model 1122 Compression and Tensile tester (or equivalent thereof) in a vertical position. The knife end plane is defined by the .0200 inch x 7 mm rectangular cross section being parallel to the base plate. An Instron Serial Number 445 load cell (with 100 gms full scale load setting) is calibrated with the top plate in position. The Instron tester is 35 run in compression mode at 0.20 inches/minute rate of descent. The apparatus can be computer or manually controlled so long as the final compression reaches a minimum of 25 grams force and data is collected sufficiently rapidly (computer assisted recommended) to determine the height at various compression values WO 01/08658 PCT/USOO/20916 33 during descent. The top plate is then moved down until the knife end establishes contact with the base plate and the zero point height is set. The knife flat end and base plate must be parallel, making contact at all points simultaneously. The knife probe is retracted to a position above the base plate allowing sufficient space to interpose a substrate. The substrate is then placed on the base plate so that the descending Flat End 5 Knife Probe can descend for the longest possible time without contacting any portion of the substrate. The Instron is then run so as to compress this trough portion of the sample with the knife blade. The sample may be maneuvered during the slow descent of the knife blade to ensure the thinnest possible substrate dimension is being measured. This is the wall thickness. The Instron is then run until a force of about 50 grams is reached during which the height and force are being continuously recorded, preferably by computer 10 print out. Additional substrate samples are similarly tested in order to establish a reliable average. The average height above the base plate at a compression value of 10 grams force is then recorded. The Crepe Ratio is then determined to be the ratio of the substrate thickness at 5 grams/in 2 measured by the Loft-Soft Method, divided by the thickness measured with the Flat End Knife Probe at 10 grams force. Surface to Saturation Ratio Methodology 15 The articles of the present invention which include a therapeutic benefit component have the therapeutic benefit component 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 20 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. 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 25 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 30 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 35 compositions of the present invention. The procedure to obtain the measurements is as follows: WO 01/08658 PCT/USOO/20916 34 Instrumental Setup: A BioRad FTS-7 spectrometer, manufactured by Bio Rad Labs, Digital Laboratory Division, located in Cambridge, MA, is used to collect the infrared spectra. Typically, the measurements consist of 100 scans at 4 cm-' resolution. The collection optics consist of a flat 60 deg ZnSe ATR crystal, manufactured by Graseby Specac, Inc., located in Fairfield, CT. Data is collected at 25'C and 5 analyzed using Grams 386 software, distributed by Galactic Industries Corp., located in Salem, NH. 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: (1) Measure the reference (background) spectrum of the cleaned, air dried cell. 10 (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 resolution). The substrate acts as an internal standard because the absorbancy of the substrate 15 alone is thus identified. Identify the main substrate peaks and wavenumbers. (3) Repeat the procedure for the substrate of the article with benefit agent applied to it. Identify the primary benefit agent'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 20 absorbance due to presence of the conditioning agent. Record the wavenumber and absorbance of several benefit agent peaks. (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 25 spectrum in step 3. (5) Calculate the ratio of each benefit agent's peak height determined in step 3 to the substrate's peak height determined in step 4. The highest number of the group represents the surface to saturation ratio for the article. The following contain some examples: 30 Substrate* Substrate Peak and Conditioner Conditioner Ratio Peak Ht. Peak Ht.

As used herein, "substantially dry" means that the articles of the present invention exhibit a Moisture 5 Retention of less than about 0.95 gins, 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 gins, 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. 10 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 & Gamble SKU 37000 63037 Basis Weight = 42.14gsm Balance Accurate to 0.Og Lexan 0.5" thickness large enough to cover samples completely and weighs 10OOg Weight A 2000g weight or combination to equal 2000g Next, weigh two paper towels separately and record each weight. Place one paper towel on flat 15 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 2000g 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. Calculate the Moisture Retention by subtracting the initial paper towel weight from the final 20 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.

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 35 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 0 C or higher.

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 5 Obtain Accurate Thermodynamic and Kinetic Data", American Laboratory, January 1994, pp 14-19, and by B. Wunderlich in Thermal Analysis, Academic Press, Inc., 1990.

A first side is prepared. A first layer of the first side is prepared which is a polyester batting having a basis weight of 2 oz/yd 2 and is comprised of a blend of fibers of about 23 microns and 40 microns 10 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 has an air permeability of about 1270 cfm/ft 2 and a foam permeability critical pressure of about 2.7 cm H 2 0. The batting is believed to be heat-bonded, utilizing no adhesive. The batting is cut into a 10 inch square. A second layer of the first side is prepared which is a 10 inch square sheet of microapertured 100 mesh formed film prepared by forming hydroapertures at high pressure 15 on a drum comprising a 100 mesh forming screen (e.g., as disclosed in U. S. Patent No. 4,629,643). The sheet is laid on the first layer with the male apertured side facing up. Twenty-five grams of the skin cleansing composition of Example 1 is placed on the center of the first side. The composition is slightly flattened, shaped to be about /2 inch thick and several inches in diameter. A layer of an impermeable polyethylene film is placed across the composition, measuring the same 10 inch square dimension as the 20 first layer. Twenty-five grams of the skin conditioning composition of Example 63 is shaped the same as the cleansing composition, and placed on top of the film in the same x-y position as the surfactant. A layer of a microapertured and macroapertured formed film which (also disclosed in U. S. Patent No. 4,629,643) is placed with the male side of the macroapertures facing towards the composition and the male side of the microapertures facing up. The layer is also cut to a 10 inch square. A last layer is prepared which is a 25 hydroentangled blend of fibers, having soft, fine denier fibers. The layer is prepared by airlaying two webs comprising 3 denier polyester (PET) fibers, one web on top of the other, each having a basis weight of about 17 gsm. A web of an elastomeric scrim having fibers of about 100 micron diameter in one direction laced with fibers of about 40 micron diameter in the other direction, laced at about 1.0 cm intervals, is fed over the fibrous webs continuously as a third web. Such a web is available from Conwed Plastics, 30 Minneapolis, MN. Fourth and fifth webs comprising 3 denier polyester fibers are airlaid at about 17 gsm each on top of the web. The webs are hydroentangled to fix them into a single web unit, and dried on drying cans until moisture free. The web is creped due to web tension during the hydroentangling and drying process and subsequent relaxation after processing. A piece of the layer is cut to a size of about 10 inches by 10 inches and placed over the top of the other layers. The layers are sealed together with a 35 pressure-platen type heat sealing device such as a Sentinel Model 808 heat sealer available from Sencorp, Hyannis, MA. A recessed (unheated) bottom plate is used which is shaped to contain the composition, and a recessed (heated) top plate which matches the bottom plate around the circular sealing rim is used to WO 01/08658 PCT/USOO/20916 94 effect a heat seal. Typical sealing conditions are 300* C for about 3.5 seconds dwell time with a supply pressure of about 30 psig to the machine, but will vary according to the sealing apparatus used.
