Abstract

Compositions, methods, and kits for caring for, treating, conditioning or durable conditioning of at least one keratinous fiber comprising at least one silicone compound comprising at least one phosphate group compound and at least one amine compound comprising greater than three amino groups, wherein the amino groups are identical or different.

Description

The present invention relates to compositions, kits comprising these compositions, and methods for using these compositions for care, treatment, conditioning or durable conditioning of at least one keratinous fiber, including at least one human keratinous fiber, comprising at least one silicone compound comprising at least one phosphate group and at least one amine compound comprising greater than three amino groups, wherein the amino groups are identical or different.

Shampoos generally comprise surfactants, such as anionic surfactants, to clean the hair. It is known that anionic surfactants not only remove the dirt and soil but also remove the naturally-present sebum from hair. Thus, shampoos may leave the hair dull and dry, that is, with what is known in the art as “creak”. This generally makes the hair extremely difficult to comb either wet or dry, and once dry, the hair may not be amenable to styling, and may have undesirable electrostatic properties, causing the hair to “fly away.” Due to the unsatisfactory condition of shampooed hair, many consumers use a conditioning composition to improve at least one of these undesirable characteristics.

Conditioning agents include cationic compounds such as cationic surfactants and cationic polymers which may render the hair more manageable, at least temporarily. For example, quaternized ammonium compounds may be used as hair conditioning agents. These compounds may be substantive to the hair due to the ionic interaction between their positive charge on the ammonium nitrogen atom and negative charges on the surface of the hair fibers. This ionic interaction, in effect, allows the conditioning agents to coat the hair shaft and thereby prevent tangling and matting of the individual hair fibers. Thus, the ability of these cationic compounds to adsorb to and/or react with the keratinous material of the hair makes them desirable compounds for conditioning the hair, such as for detangling wet hair and imparting manageability to dry hair.

However, in some cases the effect of these conditioning agents may not be long lasting. Normally, because of the weak ionic bond between the quaternized ammonium compounds and the hair fiber, the quaternized ammonium compounds are washed off the hair easily. This is especially true during shampooing, wherein anionic surfactants are present, generally in high concentrations. In such a case, the anionic surfactants in the shampoo and the cationic conditioning agents are known to form a complex which may be easily removed from the hair during the shampooing and/or which decreases the cleansing capabilities of the anionic surfactant and the conditioning capabilities of the conditioning agent.

Further, certain silicone compounds have been used as conditioning agents. However, these compounds lack durability on the hair shaft as these compounds are generally hydrophobic. Accordingly, silicone compounds may not be deposited on the hair, or are easily removed due to their weak hydrophobic interactions with the keratinous material of the hair.

Accordingly, in practice, most consumers prefer to apply an anionic surfactant-based shampoo to cleanse the hair, then rinse the hair, follow rinsing by application of a conditioner composition including a conditioning agent, such as, for example, a cationic compound, to condition the hair, and then rinse the hair again. As discussed above, this may only lead to temporary conditioning of the hair, as the next shampoo may remove the majority of the conditioning agents from the hair. Thus, there is a need for compositions and methods that condition hair, such as, for example, that impart a durable conditioning to the hair.

Compositions containing certain silicone compounds, certain amine compounds and certain silicone compounds comprising an amino group have previously been disclosed. Certain phosphated silicone polymers are known. For example, U.S. Pat. Nos. 5,070,171 and 5,149,765, the disclosures of which are hereby incorporated herein by reference, relate to phosphated silicone polymers which are disclosed to provide a nonvolatile lubricant antistat which can be applied to a variety of fibers. Further for example, U.S. Pat. No. 5,093,452, the disclosure of which is hereby incorporated herein by reference, relates to silicone phosphate organic amine salts wherein one or more pendant phosphate groups in free acid form is/are neutralized with a fatty amine group. The organic amines may be chosen from alkyl amido amines, imidazoline, alkoxyethyl alkyl amines, and alkyl tertiary amines. However, these compounds may not impart durable conditioning to at least one keratinous fiber, and may not react to condition keratinous fibers in a synergistic manner.

Further for example, U.S. Pat. No. 5,362,484, the disclosure of which is hereby incorporated herein by reference, discloses a hair care composition for conditioning hair with silicone oil comprising a stable emulsion of water-insoluble hair conditioning silicone oil dispersed in a liquid carrier composed essentially of polyoxyalkylene glycol and an emulsifier consisting of a silicone phosphate salt in which the anionic moiety comprises a copolymer of dimethylpolysiloxane and polyoxyethylene.

In essence, certain silicone compounds and certain amine compounds have been applied to hair for numerous reasons from conditioning to cleansing. Clearly, however, not all silicone compounds are the same, nor are all amine compounds the same, and thus not all combinations of silicone compounds and amine compounds impart the same properties when applied to a keratinous fiber.

The inventors have envisaged the application to at least one keratinous fiber of at least one silicone compound comprising at least one phosphate group and at least one amine compound comprising greater than three amino groups, wherein the amino groups are identical or different. In particular, the inventors have discovered that such compositions, and methods comprising applying these compositions to at least one keratinous fiber condition the at least one keratinous fiber. The compositions of the invention may also be used to care for, or treat, the at least one keratinous fiber. Further, in one embodiment, the inventive compositions impart a durable conditioning to the at least one keratinous fiber.

Thus, to achieve at least one of these and other advantages, the present invention, in one aspect, provides a composition for conditioning at least one keratinous fiber comprising at least one silicone compound comprising at least one phosphate group and at least one amine compound comprising greater than three amino groups, wherein the amino groups may be identical or different, and further wherein the at least one silicone compound and the at least one amine compound are present in a combined amount effective to condition the at least one keratinous fiber.

As described above, certain silicone compounds and certain amine compounds have been used in hair care compositions and other treatments for their detergency, surfactant and/or conditioning effect. However, it was unexpectedly discovered by the present inventors that a composition comprising at least one silicone compound chosen from a certain class of silicone compounds and at least one amine compound chosen from a certain class of amine compounds had at least one property that make it particularly desirable for use on keratinous fibers. For example, with respect to hair, compositions comprising at least one silicone compound comprising at least one phosphate group and at least one amine compound comprising greater than three amino groups (which amino groups may be identical or different) were found to condition the hair and also found to be useful in caring for and treating the hair. Further, these compositions may impart to the at least one keratinous fiber a durable conditioning even after shampooing the at least one keratinous fiber subsequent to treatment with such a composition.

Thus, in one embodiment, the present invention provides compositions for conditioning of at least one keratinous fiber comprising at least one silicone compound comprising at least one phosphate group and at least one amine compound comprising greater than three amino groups, wherein the amino groups may be identical or different, and further wherein the at least one silicone compound and the at least one amine compound are present in a combined amount effective to condition the at least one keratinous fiber.

According to the present invention, in some cases, the ratio of amino groups in the at least one amine compound to phosphate groups in the at least one silicone compound may not be determinative of the effectiveness of the inventive composition in conditioning at least one keratinous fiber as long as the at least one amine compound comprises greater than three amino groups. For example, the examples below show that the molecular weight, the concentration, and/or the nature of the silicone compound may affect the effectiveness of the composition comprising at least one silicone compound and the at least one amine compound in conditioning at least one keratinous fiber.

As previously defined, the greater than three amino groups of the at least one amine compound are chosen from primary amino groups, secondary amino groups and tertiary amino groups. In one embodiment, the greater than three amino groups are identical. In another embodiment, the greater than three amino groups are different.

Non-limiting examples of suitable polymers include homopolymers comprising greater than three amino groups, copolymers comprising greater than three amino groups, and terpolymers comprising greater than three amino groups. Thus, the at least one amine compound comprising greater than three amino groups may be chosen from, for example, polymers comprising greater than three amino groups formed from (i) at least one monomer unit comprising greater than three amino groups as defined herein, and, optionally, (ii) at least one additional monomer unit different from the at least one monomer (i); and polymers comprising greater than three amino groups formed from (i) at least one monomer comprising at least one amino group as defined herein, and, optionally, (ii) at least one additional monomer unit different from the at least one monomer (i).

The amounts of the at least one amine compound disclosed herein therefore reflect the weight percent of active material.

In one embodiment of the present invention, the at least one silicone compound and the at least one amine compound are present in the inventive composition in a synergistically effective amount to condition at least one keratinous fiber. Example 1 provides for a simple screening test, the combability test (See Garcia, M. L., and Diaz, J., J. Soc. Cosmet. Chem. 27, 370-398 (1976)), to determine the presence of synergy and what constitutes a synergistically effective amount of the at least one silicone compound and the at least one amine compound in such mixtures. The combability test is known in the art to correlate well to the amount of conditioning that is afforded hair by a composition. Wet combing work of normal hair is determined prior to treatment. The hair is then divided into three groups and treated, one group with a composition comprising both the at least one silicone compound and the at least one amine compound, a second group with a control solution containing the at least one silicone compound alone, and a third group with a control solution containing the at least one amine compound alone. The increase in work or force required to comb wet hair is compared for hair treated with the inventive composition versus the hair treated with the controls to determine if a synergistic effect is observed.

The compositions of the present invention as well as those used in the methods of the present invention may, for example, be in the form of a shampoo, a conditioner, a hair dye, a hair bleach, a permanent waving product, a relaxing product, a styling product, or a hair care product, such as a hair treatment.

Further, the inventive compositions may be acidic or basic.

In one embodiment, these compositions may further comprise at least one suitable additive chosen from additives commonly used in compositions for keratinous fibers. Non-limiting examples of the at least one suitable additive include anionic surfactants different from the at least one silicone compound and from the at least one amine compound, cationic surfactants different from the at least one silicone compound and from the at least one amine compound, nonionic surfactants different from the at least one silicone compound and from the at least one amine compound, amphoteric surfactants different from the at least one silicone compound and from the at least one amine compound, zwitterionic surfactants different from the at least one silicone compound and from the at least one amine compound, thiol compounds, fragrances, penetrating agents, antioxidants, sequestering agents, opacifying agents, solubilizing agents, emollients, colorants, screening agents (such as sunscreens and UV filters), preserving agents, vitamins, silicones, polymers such as thickening polymers different from the at least one silicone compound and from the at least one amine compound, plant oils, mineral oils, synthetic oils and any other additive conventionally used in compositions for the conditioning, care and/or treatment of at least one keratinous fiber.

Needless to say, a person skilled in the art will take care to select the at least one suitable additive such that the advantageous properties of the composition in accordance with the invention are not, or are not substantially, adversely affected by the addition(s) envisaged.

Unless otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term “about.” Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches.

Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific example are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The following example is intended to illustrate the invention without limiting the scope as a result.

EXAMPLES

Example 1

The Synergistic Effects of a Composition Comprising at Least One Silicone Compound and at Least One Amine Compound

A solution containing a combined amount of 5% by weight of Pecosil® PS100 (3.92% by weight) and Lupasol™ PR8515 (1.08% by weight) and having a pH adjusted to 6 was used to treat bleached hair swatches (0.5 g of solution/g hair). After 2 minutes of treatment, the hair swatches were rinsed with warm water for 1 minute. Before and after treatment, the force needed to comb through the wet hair swatches was determined using an Instron Tensile Tester. After the initial treatment and combability test, the hair swatches were shampooed 6 times with 10% SLES, and the combability of the shampooed hair swatches was determined. The percent improvement (% improvement) is defined as: [0078]
% Improvement=(W[0079] _b−W_a)/W_b×100%
