Description

PERSONAL CLEANING PRODUCTS TECHNICAL FIELD The present invention relates to a substantially dry and disposable personal cleaning product useful both for cleaning and conditioning the skin or hair. These products are used by the consumer when moistening the dry product with water. The product includes a water-insoluble substrate, a foaming surfactant and an oil-soluble conditioning agent The use of substrates increases foaming at low surfactant levels, increases cleaning and exfoliation and optimizes the delivery and deposition of conditioning ingredients. As a result this invention provides effective cleaning using lower levels, and therefore less irritating, of surfactant while providing superior conditioning benefits. The invention also encompasses products that include vain active ingredients for delivery to the skin or hair. The invention also encompasses a method for cleaning and moisturizing the skin and hair, using the products of the present invention and also methods to make these products BACKGROUND OF THE INVENTION Traditionally, personal cleansing products have been marketed in a variety of forms such as bar soaps, creams, lotions and gels. These cleaning formulations have tried to satisfy a number of criteria in order to be acceptable to consumers. These criteria include cleaning effectiveness, sensitivity to the skin, softness to the skin, hair, eye mucous membranes and foaming volume. The ideal personal cleansers should carefully cleanse the skin or hair, cause slight irritation or not cause irritation, and not leave the skin or hair too dry after frequent use. However, these traditional forms of personal cleansing products have the problem inherent in balancing the cleaning effectiveness against the supply of a conditioning benefit. One solution to this problem is to use separate cleaning products and conditioners. However, this is not always convenient or practical and many consumers would prefer to use a unique product that can both cleanse and condition the skin or hair. In a typical cleaning composition, the conditioning ingredients are difficult to formulate, since many conditioners are incompatible with the surfactants, which results in an inhomogeneous undesirable mixture. To obtain a homogeneous mixture with conditioning ingredients and to prevent the loss of conditioning ingredients before the deposition, additional ingredients, for example, emulsifiers, Thickeners and gelling agents are often added to suspend the conditioning ingredients within the surfactant mixture. This results in an aesthetically pleasing and homogeneous mixture, but often results in poor deposition of conditioning ingredients, since the conditioners are emulsified and not released efficiently during cleaning. Also, many conditioning agents have the disadvantage of suppressing foam generation. The suppression of foam is a problem because many consumers look for cleaning products that provide a rich, creamy and generous foam. Therefore, it is seen that conventional cleaning products that try to combine surfactants and conditioning ingredients suffer from disadvantages inherently resulting from the incompatibilities of surfactants and conditioners. There is a clear need to develop cleaning systems that provide effective cleaning and still provide sufficient conditioning in a single product. Likewise, it is highly desirable to provide cleansing and conditioning benefits from a disposable, single-use product. Disposable products are convenient, since they prevent the need to load bottles, bars, jars, uncomfortable tubes and other forms of cleaning and conditioning products. Disposable products are also a more sanitary alternative than the use of a sponge, cleaning cloth or other cleaning products proposed to be used again in multiple ways, since that said products develop bacterial growth, unpleasant odors and other undesirable characteristics related to repeated use. Surprisingly, it has been found in the present invention that the products can be developed to provide effective cleaning and conditioning in a convenient, inexpensive, disposable and sanitary personal cleaning product. The present invention provides the convenience of not needing the use of separate cleaning and conditioning products. The present invention is highly convenient for use, since it is in the form of a substantially dry product that is moistened before use. The present invention relates to a dry, disposable personal cleansing product useful both for cleaning and conditioning of hair or skin. These products are used by the consumer when moistening the dry product with water. The product consists of a substrate insoluble in water, a surfactant and a conditioner. Without being limited to theory, it is believed that the substrate increases foaming at low levels of surfactant, increases cleaning and exfoliation and optimizes the assortment and deposition of packaging ingredients. As a result, this invention provides effective cleaning by using lower, and therefore less irritating, levels of surfactant, while providing superior conditioning benefits. Also, it has been found that these products are useful for providing a wide range of active ingredients for the skin or hair during the cleaning process.
Therefore, an object of the present invention is to provide substantially dry products for cleaning and conditioning the skin or hair characterized because the products are used in combination with water. It is another object of the present invention to provide products that include a water insoluble substrate, a surfactant and a conditioning component. Another object of the present invention is to provide products that are disposable and proposed for single use. It is another object of the present invention to provide products that are soft to the skin or hair. It is another object of the present invention to provide useful products for delivering active ingredients to the skin or hair during the cleaning and conditioning process. It is another object of the present invention to provide cleaning and conditioning methods to the skin or hair. It is another object of the present invention to provide methods of manufacturing the products of the present invention. This and other objects of this invention will be apparent in the light of the following description.
BRIEF DESCRIPTION OF THE INVENTION The present invention relates to a disposable cleaning and conditioning product, for personal care and single use, which is substantially free of C12-15 alcohol benzoates including: (A) a water insoluble substrate, (B) an agent foaming surfactant, and (C) an oil-soluble conditioning agent, wherein the entire product is substantially dry. In further embodiments, the present invention relates to a disposable, single use personal conditioner and cleaning product that is substantially free of C12-15 alcohol benzoates, consisting of: (A) a water insoluble substrate , and (B) a cleaning and conditioning composition that includes: (i) a foaming surfactant, and (ii) an oil-soluble conditioning agent, wherein said foaming surfactant and said oil-soluble conditioning agent are added or impregnated. separately or simultaneously in said water-insoluble substrate, and wherein the weight ratio of the foaming surfactant to the oil-soluble conditioning agent is less than about 20: 1, and wherein the product is substantially dry.
In additional embodiments, the present invention relates to a method for manufacturing a conditioner and personal cleansing product for single use, disposable, which is substantially free of C12-15 alcohol benzoates, consisting of the step of adding separately or simultaneously onto or impregnated into a water-insoluble substrate: (A) a foaming surfactant, and (B) a oil-soluble conditioning agent, and wherein the weight ratio of the foaming surfactant to the oil-soluble conditioning agent is less than about 20: 1, and wherein the product is substantially dry.
In other embodiments, the present invention relates to methods for cleaning and conditioning the hair or skin with the personal cleansing products described herein. In still other embodiments, the present invention relates to methods for depositing conditioning agents on the skin or hair. All percentages and ratios used herein, unless otherwise specified, are by weight and all measurements made are at 25 ° C, except those otherwise designated. The invention herein may include, consist of, or consist essentially of essential ingredients and components, as well as optional ingredients and components described herein.
DETAILED DESCRIPTION OF THE INVENTION The personal cleansers of the present invention are highly effective in cleaning hair or skin, and still provide effective deposition of conditioning agents. The products may also contain other active ingredients that can be deposited on the skin or hair. Without being limited to theory, it is believed that the substrate contributes significantly to the generation of foam and deposition of conditioning agents and other active ingredients. It is believed that this increase in foaming is the result of the action on the surface of the substrate. As a result, milder and significantly lower amounts of surfactants can be employed. It is believed that the reduced amount of surfactant required is related to the reduction in the drying effect of the skin or hair by the surfactants. In addition, the reduced amount of the surfactant drastically decreases the inhibitory action (for example, via emulsification or direct removal by the surfactants) or surfactants to deposit the conditioning agents. Without being limited to theory, the substrate also increases the deposition of conditioning agents and active ingredients. Since the invention is in dry form, the invention does not require emulsifiers that inhibit the deposition of conditioning agents and active ingredients. Also, since the skin conditioners and active ingredients are dried or impregnated in the substrate, they are transferred directly to the skin or hair by contacting the surface of the wet product with the skin Finally, the substrate also increases the cleanliness The substrate can have different textures on each side, for example a rough side and a soft side The substrate acts as an effective foaming agent and exfoliating product. When physically entering into contact with skin or hair, the substrate significantly helps to clean and remove dirt, makeup, dead skin cells and other debris. By a "foaming surfactant" is meant a surfactant, which when combined with water and mechanically stirred generates a foam or suds. Preferably, these surfactants must be soft, which means that these surfactants provide sufficient cleaning or detersive benefits , but they do not dry the skin or hair too much and still gather the foaming material described above. The terms "disposable" or "single use" are used here in their ordinary meaning to mean a product that can be discarded or discarded after use. The term "activated in water" as used herein, means that the present invention is presented to the consumer in dry form for use after wetting with water. It was found that these products produce a foam or are "activated" when in contact with water. and more agitation The term "substantially dry" as used herein means that the product is substantially free of water and usually feels dry to the touch. The products of the present invention include less than about 10% by weight of water, preferably less than about 5% by weight of water and more preferably less than about 1% by weight of water, the above measured in a dry environment, for example low humidity. Those skilled in the art will recognize that the water content of a product as in the present invention can vary with the relative humidity of the environment. The term "soft" as used herein in reference to the foaming surfactants and products of the present invention means that the products of the present invention demonstrate comparable skin softness with an alkylglyceryl ether sulphonate surfactant (AGS) based on a bar synthetic, for example synbar bar. Methods to measure the mildness or vice versa the irritability of a surfactant, which the products contain, are based on a skin bar destruction test. In this test, while the surfactant is softer, the skin bar will be less destroyed. The destruction of the skin bar is measured by the relative amount of water labeled with radium (marked with tritium) (3H-H20) that passes from the test solution through the epidermis of the skin into a physiological pH enhancer content in the diffused camera. The test is described by T.J.Franz in J. Invest. Dermatol .. 1975,64, pp. 190-195; and in U.S. Patent No. 4,673,525 to Small et al., issued June 16, 1987, which they are incorporated here by reference in their entirety. Other test methodologies for determining the surfactant softness well known to those skilled in the art can also be used. The personal care products of the present invention include the following essential components. The composition, which is impregnated or applied to the substrate, consists essentially of one or more surfactants and one or more conditioning agents. Additional active ingredients may also be included within the composition. An alternative and preferred method is to apply each ingredient separately to the substrate. In embodiments where only an oil-soluble conditioning agent is required, these cleaning and conditioning products are substantially and preferably free of benzoate of C12-15 alcohols, for example free of benzoic acid esters of alcohols having mainly about 12 to around 15 carbon atoms. See International Cosmetic Ingredient Dictionary, Fifth Edition, 1993, p. 87, which is incorporated herein by reference in its entirety. Also, "substantially free of benzoates of C12-15 alcohols" means less than about 1%, preferably less than about 0.5% and more preferably less than about 0.25% by weight of the cleaning and conditioning composition, which includes the surfactant foaming agent and the oil-soluble conditioning agent.
SUBSTRATE INSQLUBLE IN WATER The products of the present invention include a water insoluble substrate. By "insoluble in water" it is meant that the substrate does not dissolve in or break easily due to immersion in water. The water-insoluble substrate is the product or vehicle for supplying the foaming surfactant and the conditioning component of the present invention to the skin or hair for cleaning or conditioning. Without being limited to the theory, it is believed that the substrate, by providing mechanical stirring, provides a foaming generation effect and also aids in the deposition of the conditioning component. A wide variety of materials can be used as the substrate. The following non-limiting characteristics are desirable: (i) sufficient wetting force to be used, (ii) sufficient abrasivity, (iii) sufficient bulging and porosity, (iv) sufficient thickness and (v) appropriate size.

CONDITIONER COMPONENT The products of the present invention include an oil-soluble conditioning agent that is useful for providing a conditioning benefit to the skin or hair during use of the product. The oil-soluble conditioning agent comprises from about 1% about 99%, preferably about 2% about 50% and more preferably about 3% about 25% by weight of said water-soluble substrate. The oil-soluble conditioning oil is selected from one or more oil-soluble conditioning agents, so that the heavy arithmetic average solubility parameter of the oil-soluble conditioning agent is less than or equal to 10.5. It is recognized, based on its mathematical definition of solubility parameters, that it is possible, for example, to achieve the required arithmetic mean solubility parameter, for example, less than or equal to . 5, for an oil-soluble conditioning agent that includes two or more compounds, if one of the compounds has an individual solubility parameter greater than 10.5. Solubility parameters are well known in formulation chemistry for those skilled in the art and are routinely used as a guide for the compatibility and solubilities of materials in the formulation process. The solubility parameter of a chemical compound, d, 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 contributions of the additive group for the heat of vaporization and the molar volume of the components of that compound, using the following equation: where S, S, = the sum of the heat of vaporization of the additive group contributions, and S, m, = the sum of the contributions of the molar volume additive group. Standard vaporization heat tabs 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 Solubilitv Parameters. CRC Press, Chapter 6, Table 3. Pp. 64-66 (1985), which is unofficial here by reference 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," Polvmer Enqineerinq and Science, vol. 14, no. 2, pp. 147-154 (February 1974), which is incorporated herein by reference in its entirety. The solubility parameters obey the laws of mixtures, so the solubility parameter for a mixture of matepals is given by the heavy arithmetic medium (for example, the heavy average) of the solubility parameters for each component of that mixture. See, Handbook of Chemistrv and Phvsiscs. 57th edition, CRC Press, p. C-726 (1976-1977), which is hereby incorporated by reference in its entirety. The formulation chemicals typically report and use solubility parameters in units of (cal / cm3) 1'2. The tabulated values of contributions of additive groups for heat of vaporization in Handbook of Soiubilitv Parameters are reported in units of Kj / mol. However, this tabulated heat of vaporization values is easily converted to cal / ml using the following well-known relationships: 1 J / mol = 0.239006 cal / mol and 1000 J = 1 Kj.
See Gordon, A.J. et al., The Chemist's Companion. John Wiley & Sons, pp. 456-463. (1972), which is unofficial here by reference in its entirety. The solubility parameters have also been tabulated for a wide variety of chemical materials. Solubility parameter tabulations are found in the aforementioned Handbook of Solubilitv Parameters.
