The past in the cup

Traditionally, personal care products have been marketed in a variety of forms such as soap bars, creams, lotions and gels. The compositions of these cleaning compositions attempt to satisfy a number of criteria acceptable to consumers. These criteria include effective cleansing, skin feelings, softening of skin, hair, and eye softening and foam formation. Ideal personal cleaners must gently cleanse the skin or hair, cause little or no moisture, and not leave the skin or hair feeling dry when used frequently.

These traditional forms of personal cleaners have a fundamental problem between the balance of the cleaning effect and the use of conditioner conditioning-care capabilities. One solution to this problem is to use a separate detergent and conditioner. However, this •. · Flf flf fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fl fll fll fll fll fll fll fll fll fll fll fll fll fll fll fll flll fllll flll skin or hair. In a typical cleaning composition, the treatment components are difficult to formulate because many conditioning agents are incompatible with surfactants, resulting in an undesirable inhomogeneous composition. Additives such as emulsifiers, thickeners, or gelling agents are often added to produce a homogeneous composition with the conditioning components and to prevent loss of these components prior to storage, keeping the conditioning ingredients in suspension in the mixture with the surfactant. The result is an aesthetically pleasing homogeneous composition, but also often results in the deposition of a small amount of conditioner components, since these components are emulsified and are not significantly deposited during cleaning. Also, many such conditioners have the drawback of suppressing foaming. Suppressing foaming is a problem because many consumers are seeking foaming agents that provide a rich, creamy and pleasant foam.

It can be seen that conventional cleaning products attempting to combine a surfactant with conditioners suffer from disadvantages resulting primarily from the incompatibility of the surfactant and the conditioner. There is a clear need for the development of a cleansing system in a single product that ensures efficient cleaning and also ensures that sufficient conditioner is deposited on the treated skin or hair.

Po.ds.tatavy invention

It is highly desirable to provide a cleaning and care effect in a single readily and easily removable product. A disposable and irreversible product is suitable because it avoids the need to carry uncomfortable vials, cubes, cups, tubes and other forms of both the cleansing product and the conditioner. The products available also represent a more hygienic alternative to the use of a sponge, cleaning pad or other cleaning aids for more frequent use, since they allow the growth of bacteria, produce an unpleasant odor and also have other unpleasant characteristics associated with repeated use.

Through the present invention, it has been discovered that an article can be prepared which guarantees effective cleaning and appropriate treatment in a single, unpretentious and hygienic personal cleaning article; The present invention guarantees the convenience of avoiding the need to use both, the cleaning composition and the conditioner separately. The present invention is highly convenient to use as it is in the form of a substantive dry product that only needs to be wetted before use.

Another object of the invention is to provide an article of manufacture comprising a water-insoluble substrate, a surfactant, and a conditioning component.

Another object of the present invention is to provide a suitable, readily removable article, subject to separate use.

It is a further object of the present invention to provide a skin and hair pleasant composition.

It is a further object of the present invention to provide a product delivering active components to the skin or hair during the cleaning and care process.

Another object of the present invention is to provide a method of cleansing and treating the skin or hair.

Another object of the present invention is to provide production of the compositions of the present invention.

These and other objects of the invention are illustrated in the following explanation.

The present invention relates to a readily disposable personal cleansing and care composition for single use, comprising:

(A) a water-insoluble substrate (B) a foaming surfactant, and (C) a water-soluble conditioning agent, wherein said product is substantively dry.

In another aspect, the present invention discloses a readily disposable personal care cleaning and care product comprising:

(A) a water-insoluble substrate, and (8) a cleaning and conditioning component, comprising:

(i) a foaming surfactant, and (ii) a water-soluble conditioning agent, wherein said foaming surfactant and said water-soluble conditioning agent are individually or together added or impregnated into said water-insoluble substrate, and a foaming weight ratio of foaming agent. the surfactant to the water-soluble conditioning agent is less than about 8: 1, wherein said product is substantively dry.

In another aspect, the present invention provides a process for the manufacture of a ready-to-use disposable personal care cleaning and care product in which a foaming surfactant, (A) a foaming surfactant, and (B) a water-soluble conditioner is gradually added or impregnated wherein the weight ratio of the foaming surfactant to the water-soluble conditioning agent is less than about 8: 1, and said resulting product is substantively dry.

In another aspect, the present invention relates to a process for cleaning and treating the skin and hair with the personal cleansing product described herein.

Another aspect of the present invention is a method of depositing a conditioner on the skin or hair.

All percentages and ratios used herein, unless otherwise indicated, are by weight and all measurements were made at 25 ° C unless otherwise noted. The present invention may comprise, be composed of or comprise essences, as well as be composed of the essences described herein and preferred ingredients and components.

The personal cleansing products of the present invention are highly efficient in both skin or hair cleaning and efficient deposition of conditioning agents. The articles may also contain other active ingredients deposited on the skin or hair.

Without being limited by theory, it is believed that the substrate significantly contributes to the formation of foam and deposition of conditioning agents or other active components. It can be assumed that the increased foaming is due to the surface reaction of the substrate. As a result, a milder and significantly less surfactant is used. A reduction in the amount of surfactant required will significantly translate into a decrease in the drying effect of the skin and hair by the surfactant. Further, a reduced amount of surfactant will dramatically reduce the inhibitory effect (i.e., by emulsifying or by direct removal of the surfactant) of the surfactant deposition conditioner.

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

Finally, the substrate also promotes cleaning ability. The substrate may have a different texture on each side, i.e. it may be both coarse and fine. The substrate acts as a powerful foaming and refining tool. Because it comes into physical contact with the skin or hair, the substrate significantly helps in cleaning and removing dirt, makeup, dead skin and other residues.

By the term "foaming surfactant" is meant a surfactant which, in combination with water and mechanical spreading, provides foam or suds. Preferably, such a surfactant must be gentle, which means that such a surfactant provides sufficient cleansing or detersive effect while not drying the skin or hair, yet still providing the foaming criteria described previously.

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

As used herein, the term "water-activated" means that the present invention is presented to the consumer in dry form, for use after wetting with water. It is emphasized that these products produce foam or are not "activated" on contact with water and subsequent spreading.

The term "substantively dry" as used herein means that the product is substantively anhydrous and is generally perceived to be dry when touched. The product of the present invention comprises 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 will be appreciated by conventional experience that the water content of the article of the present invention may vary according to the relative humidity of the environment.

The term " fine " used in relation to the foaming surfactant and the product of the present invention means that the product of the present invention acts gently on the skin as compared to the fine alkyl glycerin ether sulfonate (AGS) surfactant based on synthetic soap, i. synbaru. Methods for determining the pleasantness or inversity of a surfactant component are based on the skin barrier disruption test. According to the test, the finer the surfactant component, the less breakdown of the skin barrier. The degree of skin barrier disruption is measured based on the relative amount of radio-labeled (tritium) water (3H-H ₂ O) passing through the skin epidermis into the physiological buffer contained in the diffusion chamber. The test is described by TJFranz v

J. Invest.Dermatol, 1975, 64, pp. 190-195; and in U.S. Patent No. 4,673,525 to Smali et al. on June 2, 1987, both of which are incorporated herein by reference. Other test procedures for determining the fineness of a surfactant are well known to those skilled in the art and can also be used.

The care products of the present invention comprise the following essential components. The composition, which is either impregnated or deposited on the substrate, contains essence one or more surfactants and one or more kinds of conditioners. Other active components may also be added to the composition. An alternative preferred method is to apply each component to the substrate separately.

The solubility parameter is well known to the skilled chemist in formulating the formulation of the articles and is routinely used as a guide for determining the kDability 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 density of the compound. Typically, the solubility parameter is determined from the tabulated values by adding the contribution of each group to the heat of evaporation and the molar volume of the component of this compound, according to the following equation:

I / 2

Σει

ΣπΥ | and

where Σ, Ε, = sum of the evaporative heats of the contributing additive group, and Zim, = sum of the molar volume of the contributing additive group.

Standard tabulated values of evaporative heats and molar volumes of contributing additive groups for a wide range of atoms and atomic groups 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, FLF., &Quot; A Method for Estimating Both Solubility Parameters and Molar Volumes of Liquids, Polymer Engineering and Science, vol. 14, No. 2, pp. 147-154 (February 1974). ), and are also fully incorporated by reference.

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

Composition chemists usually utilize solubility parameters in units (cal / cm ³ ) ^{, z} .
