FOR SINGLE USE, METHOD OF ITS PRODUCTION AND USE t

Technical field

The present invention relates to substantially dry, disposable personal cleansing products useful for both cleansing and conditioning the skin and hair. The products can be used by a consumer after wetting the dry product with water. The product comprises a water-soluble substrate, a foaming surfactant and a conditioner, which further comprises an oil-soluble treatment agent and a similar water-soluble agent.

The use of a foam-enhancing substrate at low surfactant levels increases cleaning power and ease of spreading and optimizes the uptake and deposition of treatment ingredients. The result of the invention is a guarantee of effective cleaning using low and thus less irritating surfactant levels while achieving peak treatment agent efficacy.

The invention also includes products containing various active components delivered to the skin or hair.

The invention also includes a method for cleansing and moisturizing the skin and hair using a product according to the present invention, as well as a procedure for working with these products.

Personal cleansing products have traditionally been marketed in a variety of forms such as bars, creams, lotions and gels. The formulation of these cleansing products attempts to satisfy a number of criteria acceptable to consumers. These criteria include effective cleansing, skin feel, skin, hair and eye moisturization, and foaming. Ideal personal cleansing products must gently cleanse the skin or hair, provide little or no moisture, and not leave the skin or hair feeling dry with frequent use.

These traditional forms of personal cleansers have a fundamental problem between balancing the cleansing effect and utilizing the conditioning ability. One solution to this problem is to use a separate cleanser and conditioner. However, this • · · · · · · · * * • · · fc ♦ « ···· • · · · · · · · * v · ·

2* fcfcfcfc fcfc · · · « fcfcfc fcfcfc • · fcfc*· · · « • fcfc fc fcfc fcfc ·· fcfc is not always convenient or practical, and many consumers prefer to use a single product that provides both cleansing and conditioning of the skin or hair. In a typical cleansing composition, the conditioning components are difficult to formulate because many conditioning agents are not compatible with surfactants, resulting in an undesirable inhomogeneous mixture. To produce a homogeneous mixture with the conditioning components and to prevent loss of these components prior to deposition, additives such as emulsifiers, thickeners, or gelling agents are often added to keep the conditioning components in suspension in the mixture with the surfactant. The result is an aesthetically pleasing homogeneous mixture, but also often results in the deposition of a small amount of the conditioning components, since these components are emulsified and not significantly deposited during cleansing. Also, many such conditioning conditioners have the disadvantage of foam suppression. Foam suppression is a problem because many consumers seek foaming agents that provide a rich, creamy, and pleasant lather.

It is apparent that conventional cleansing products attempting to combine surfactants with conditioners suffer from disadvantages resulting primarily from the incompatibility of the surfactant and the conditioning conditioner. There is a clear need to develop a cleansing system in a single product that ensures effective cleansing and also ensures that a sufficient amount of conditioner is deposited on the treated skin or hair.

It is highly desirable to deliver a cleaning and conditioning effect in a single, ready-to-use, easily disposable product. A ready-to-use, non-returnable product is convenient because it eliminates the need to carry around inconvenient bottles, cubes, cups, tubes, and other forms of both cleaning product and conditioner. The available products also represent a more hygienic alternative to using a sponge, cleaning stick, or other cleaning aids intended for frequent use, as these aids allow for bacterial growth, emit unpleasant odors, and have other unpleasant characteristics associated with repeated use.

Through the present invention, it has been discovered that a product can be prepared that provides effective cleaning and appropriate treatment in a single, convenient and hygienic personal cleansing product. The present invention provides convenience in that it is not necessary to use both the cleanser and conditioner separately. The present invention is highly convenient to use because it is in the form of a substantially dry product that only needs to be moistened before use.

The present invention describes a dry, disposable personal cleansing product useful for both cleansing and treating the skin or hair. These products are used by the consumer after wetting

The present invention may comprise, be composed of, or contain essences, as well as be composed of the essences and optical additives and components described herein.

The personal cleansing product of the present invention is highly effective in both cleansing the skin or hair and effectively depositing a conditioning agent. The product may also contain other active ingredients deposited on the skin or hair.

Without being limited by theory, it is believed that the substrate contributes significantly to the formation of foam and the deposition of conditioning agents or other active components. It is believed that the increased foaming is a result of the surface reaction of the substrate. As a result, it is possible to use a milder and significantly lower amount of surfactant. The reduction in the amount of surfactant required will significantly reduce the drying effect of the surfactant on the skin and hair. Furthermore, the reduced amount of surfactant will dramatically reduce the inhibitory effect (i.e., by emulsification or direct removal by the surfactant) of the surfactant on the deposition of the conditioner.

Without being limited by theory, the substrate also promotes the deposition of the conditioner and active ingredients. Since the invention is in dry form, the invention does not require emulsifiers to prevent the deposition of the conditioner and active ingredients. Furthermore, since the skin conditioner and active ingredients are dried or impregnated onto the substrate, they are transferred directly to the skin or hair upon contact of the wetted product with the skin.

Finally, the substrate also supports the cleansing ability. The substrate can have different textures on both sides, i.e. it can be both coarse and fine. The substrate acts as a powerful foaming and softening tool. Because it comes into physical contact with the skin or hair, the substrate significantly assists in cleansing and removing dirt, makeup, dead skin cells and other debris.

The term "foaming surfactant" refers to a surfactant which, when combined with water and mechanically agitated, produces a foam or lather. Preferably, such a surfactant must be mild, meaning that such a surfactant provides sufficient cleaning or detersive action but does not dry out the skin or hair, and yet still provides the foaming criteria described earlier.

The terms "disposable" or "single-use" are used herein in their ordinary meaning and refer to a product intended to be disposed of or destroyed after a single use.

• · ··· • · · • · · ·· » · · ·« · «

The term "water-activated" as used herein means that the present invention is presented to the consumer in a dry form, for use after being moistened with water. It is emphasized that these products produce foam or are "activated" upon contact with water and further application.

The term "substantially dry" as used herein means that the product is substantially anhydrous and generally feels dry to the touch. The product of the present invention contains less than about 10% by weight of water, preferably less than about 5% by weight of water, most preferably less than about 1% by weight of water, determined in a dry environment, i.e., at low humidity. It is recognized from ordinary experience that the water content of a product of the type of the present invention may vary with the relative humidity of the surrounding environment.

The term "mild" as used herein in relation to the foaming surfactant and the product of the present invention means that the product of the present invention is gentle on the skin compared to a mild alkylglycerin ether sulfonate (AGS) surfactant based on synthetic soap, i.e. synbar. Methods for determining the pleasantness; or inversely the unpleasantness of a surfactant are based on a skin barrier disruption test. According to the test, the milder the surfactant, the less the skin barrier is disrupted. The degree of skin barrier disruption is measured based on the relative amount of radiolabeled (tritiated) water (3H- _H2O ) passing through the skin epidermis into a physiological buffer contained in a diffusion chamber. The test is described by TJ Franz in J.Invest.Dermatol, 1975, 64, pp. 190-195; and in U.S. Pat. No. 4,673,525, Smali et al., issued June 16, 1987, both of which are incorporated herein by reference. Other test procedures for determining surfactant fineness are well known to those skilled in the art and may also be used.

The personal care products of the present invention contain the following essential components. The composition, which is either impregnated or applied to the substrate, contains essentially one or more surfactants and one or more types of conditioners. Other active components may be added to the composition. An alternative preferred method is to apply each component to the substrate separately.

Water-insoluble substrate

The product of the present invention comprises a water-insoluble substrate. "Water-insoluble" means that the substrate does not dissolve in water or disintegrates when placed in water.

The water-insoluble substrate and conditioner of the present invention cleanse and condition the skin or hair. Without being limited by theory, it is believed that the substrate, upon mechanical agitation, will form a lather and help to provide deposition of the conditioning agent.

A variety of materials can be used as the substrate. The following non-limiting characteristics are required: (i) sufficient moisture in use, (ii) sufficient abrasiveness, (iii) sufficient density and porosity, (iv) sufficient thickness, and (v) appropriate grain size.

Non-limiting examples of suitable insoluble substrates meeting the above criteria include nonwoven substrates, woven substrates, water and air felt substrates, natural sponges, synthetic sponges, polymer meshed substances, and the like. Preferred substrates include nonwoven substrates because they are economical and readily available in a variety of materials. By nonwoven substrates is meant herein fibrous materials that are not woven into a fabric but rather arranged in layers, mats, or pads. The fibers may be randomly arranged (i.e., randomly arranged) or may be carded (i.e., oriented preferentially in one direction by a comb). Finally, nonwoven substrates may be composed of a combination of randomly arranged layers and carded fibers.

Nonwoven substrates can consist of a variety of materials, both natural and synthetic. Natural materials are materials derived from plants, animals, insects, or by-products of plants, animals, or insects. Synthetic materials are materials obtained primarily from various man-made materials or by modifying natural materials. Conventional materials are usually based on a fibrous fabric composed of some common synthetic or natural textile material, or a mixture thereof.

Non-limiting examples of natural materials suitable for use in the present invention include silk fibers, keratin fibers, and cellulose fibers. Non-limiting examples of keratin fibers include those selected from the group consisting of wool fibers, camel hair, and the like. Non-limiting examples of cellulose fibers include those selected from the group consisting of wood pulp fibers, cotton fibers, hemp fibers, jute fibers, flax fibers, and mixtures thereof.

Non-limiting examples of synthetic materials useful in the present invention include those selected from the group consisting of acetate fibers, acrylic fibers, cellulose ester fibers, modacrylate fibers, polyamide fibers, polyester fibers, polyolefin fibers, polyvinyl alcohol fibers, rayon, polyurethane foam, and mixtures thereof. Examples of some of these synthetic materials include acrylates, such as acrylate, cresate, and fibers.

These and other suitable fibers and nonwovens for this purpose 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. U.S. Patent No. 4,891,227, Thaman et al., issued January 2, 1990; U.S. Patent No. 4,891,228, all of which are incorporated herein by reference in their entirety.

Nonwoven substrates made from natural materials include webs or sheets, most often prepared by sedimentation of liquid suspensions of these fibers on fine metal screens. See C.A.Hampel et al., The Encyclopedia of Chemistry, 3rd ed., 1973, pp. 793-795 (1973); The Encyclopedia of America, vol. 21, pp. 376-383 (1984); and G.A.Smook, Handbook of Pulp and Paper Technologies, Technical Association for the Pulp and Paper Industry ((986); all of which are incorporated herein by reference in their entirety.

Substrates made from natural materials and suitable for use in the present invention can be obtained from a wide variety of commercial sources. Non-limiting examples of suitable commercially available paper laminate substrates suitable herein include Airtex ^R , an air-laid embossed laminate, with a basis weight of about 85 g/m ² , available from James River, Green Bay, Wi; and Walkisoft ^R , an air-laid embossed cellulose material with a basis weight of about 90 g/m ² , available from Walkisoft USA, Mount Holly, NC.

Methods for preparing nonwoven substrates are well known. In general, such nonwoven substrates can be produced by air layup, water layup, meltblown, forming, spinning or carding, whereby the fibers are first cut to the desired length from long bundles, passed into a water or air stream, and then deposited onto a substrate by a deposition stream of water or air. The resulting layer, regardless of the production method, is then subjected to at least one bonding operation to anchor the individual fibers to form a self-supporting web. According to the present invention, the nonwoven layer can be prepared by various processes including water-based, thermal or thermal bonding, or a combination of these processes. The substrates according to the present invention can be single-layer or multi-layer. At the same time, multi-layer substrates can contain films or other non-fibrous materials.

Alternatively, a polymerized reticulated sponge can be used as the water-insoluble substrate, as described in European Patent No. EP 702550 A1, published March 27, 1996, and incorporated herein by reference. The polymerized sponge comprises a plurality of interlocked and extruded tubular reticulations prepared from a strong flexible polymer, such as an addition polymer of olefinic monomers and polycarboxylic acid polyamides. Although these polymerized sponges are intended for use in conjunction with a liquid cleaning agent, these types of sponges can be used as the water-insoluble substrate of the present invention.

The substrate can be prepared in a wide variety of shapes and forms including flat pads, thick pads, thin sheets, ball-shaped particles, irregularly shaped particles, and • 4

Particularly suitable are square, round, rectangular or oval pads with a surface area of from about 6 cm ² to about 930 cm ² , preferably from about 65 cm ² to about 770 cm ² , and more preferably from about 193 cm ² to about 516 cm ² and a thickness of from about 0.025 mm to about 12.5 mm, preferably from about 0.125 mm to about 6.25 mm, more preferably from about 0.25 mm to about 2.5 mm.

The water-insoluble substrates of the present invention may comprise two or more layers, each with a different texture and abrasiveness. The different textures may result from the use of different combinations of materials or from a different manufacturing process or combination thereof. The dual texture of the substrate may provide the advantage that the more abrasive side is more suitable for particle removal and the softer, absorbent side for gentle cleaning. Another advantage is that the separate layers of the substrate may be prepared with different colorations to help the user distinguish the type of surface.

Foaming surfactants

The products of the present invention contain from about 0.5% to about 12.5%, preferably from about 0.75% to about 11%, more preferably from about 1% to about 10%, of foaming surfactant based on the weight of the water-insoluble substrate.

By foaming surfactant is meant a surfactant that, in conjunction with water and mechanical friction, foams or forms a lather. Preferably, these surfactants or combinations thereof must be mild, meaning that these surfactants provide sufficient cleaning or detersive properties but do not dry out the skin or hair, and yet meet the foaming criteria described above.

In this case, various surfactants are suitable, selected from the group of anionic foaming surfactants, nonionic foaming surfactants, amphoteric foaming surfactants and mixtures thereof. Cationic surfactants may also be used as a preferred component provided that they do not adversely affect the overall foaming characteristics of the desired foaming surfactant.

The solubility parameter is well known to experienced chemists when formulating product compositions and is routinely used as a guide to determine the compatibility and solubility of materials during the formulation process.

The solubility parameter of a chemical compound, δ, is defined as the square root of the cohesive energy of the density of that compound. Commonly, the solubility parameter is determined from tabulated values by adding the contributions of individual groups to the heat of vaporization and the molar volume of the component of that compound, according to the following equation:

1/2

Σ _Εί i

Change it

where Σ,Ε, = sum of the heats of vaporization of the contributing additive group, and = sum of the molar volumes of the contributing additive group.

Standard tabulated values of the heats of vaporization and molar volumes of the contributing additive group for a wide range of atoms and groups of atoms are summarized in Barton, A.F.M. Handbook of Solubility Parameters, CRC Press, Chapter 6, Table 3, pp. 64-66 (1985), and are also incorporated by reference. The above equation for the solubility parameter is described in Fedors, R.F., "A Method for Estimating Both the Solubility Parameters and Molar Volumes of Liquíds, Polymer Engineering and Science, vol. 14, no. 2, pp. 147-154 (February 1974), and are also fully incorporated by reference.

Solubility parameters follow the mixing law, i.e., the solubility parameter of a mixture of materials is given by the arithmetic mean (i.e., weight average) of the solubility parameters of each component of the mixture. See: Handbook of Chemistry and Physics, 57th ed., CRC Press, pp. C-726 (1976-1977), which is also fully incorporated by reference.

Formulation chemists typically use solubility parameters in units of (cal/cm ³ ) ^V2 .

The amount of conditioning agent deposited on the skin or hair can be determined by various well-known standard analytical procedures known to chemists skilled in the art. Such procedures include, for example, extraction from the skin or hair surface with a suitable solvent followed by chromatographic analysis (i.e., e.g., gas chromatography, liquid chromatography, supercritical fluid chromatography, etc.), IR spectroscopy, UV/VIS spectroscopy, mass spectrometry, etc. Direct measurements can be made on the skin and hair by techniques such as IR spectroscopy, UV/VIS spectroscopy, opacity measurements, fluorescence spectroscopy, ESCA spectroscopy, and the like.

In a typical procedure for determining the amount deposited, the product of the present invention is moistened with water and kneaded and spread to form a foam. The product is then spread for about 15 seconds on the skin or scalp over a spot of about 25 cm ² to about 300 cm ² , preferably 50 cm ² to about 100 cm ² , which is marked with a suitable indelible marker. The spot is then rinsed with water for about 10 seconds and then air dried for about 10 minutes. The spot is then extracted and the extract is analyzed, or it is analyzed directly using the technique recommended above.
