Description

Styling shampoo composition

The present invention relates to a styling shampoo composition that increases the amount of coacervate produced by the anionic detergent and the styling polymer.

In general, shampoo is used to keep hair and scalp clean and beautiful by removing contamination of hair and scalp, but it is also used for additional shine and protection of hair.

Recently, consumers are trying to give hair a certain amount of hair by maintaining a certain shape to maintain beauty or stress caused by the hair. In general, after shampooing, styling products such as gel, mousse, spray, and wax are used. It is made by applying to the hair. However, the styling product has to apply a separate styling product after the use of the shampoo, and hassle to wash the hands after the application.

Therefore, as an attempt to solve this problem, products that add styling polymers and silicone elastomers to shampoo products have been studied. However, in the case of cleaning products such as shampoos, the amount of active ingredients adsorbed to the hair is extremely small due to the characteristics of the product. There is a limit.

Therefore, in order to solve this problem, efforts to increase the adsorption amount of these styling polymers and silicone elastomers on the hair have been continuously studied.

Recently, U.S. Patent Publication No. 2003/0199403 attempts to increase the adsorption of solid particle components effective for hair and scalp by coacervates produced by anionic surfactants and cationic polymers, and U.S. Patent Publication No. 2004/0146475 The study discloses a study to enhance the formation of coacervates in conditioning shampoos through the appropriate combination of ethoxy and sulfate levels of cationic cellulose polymers and anionic surfactants. U.S. Patent No. 5,977,036 discloses a study to increase the adsorptive effect of a styling polymer effective on hair by coacervates produced by anionic surfactants and cationic polymers.

However, all of them have a disadvantage in that coacervate is generated by a combination of anionic detergent and a general cationic polymer, so that the amount of coacervate is not high, and thus it is not easy to show a styling effect on the hair.

Therefore, the technical problem to be achieved by the present invention is to provide a styling shampoo composition to increase the amount of coacetate produced to enhance the hair adsorptive effect of the styling polymer and / or silicone elastomer by these coacetate.

In order to achieve the above technical problem, the present invention is a shampoo composition comprising an anionic surfactant and a styling polymer, quaternary ammonium cationic surfactant represented by the formula (1), more preferably 4 represented by the formula (1) A styling shampoo composition is provided comprising a quaternary ammonium cationic surfactant and a silicone elastomer.

In Formula 1, R is any one selected from the group consisting of a linear alkyl group having 12 to 22 carbon atoms, branched alkyl group, alkenyl group and alkylamide, n is an integer of 0 to 10, X is halogen, sulfate and Any one selected from the group consisting of acetate.

More preferably, the present invention provides a styling shampoo composition, characterized in that the content of the quaternary ammonium cationic surfactant in the styling shampoo composition is 0.1 to 10% by weight relative to the total weight of the composition.

Hereinafter, the styling shampoo composition of the present invention will be described in more detail.

The styling shampoo composition according to the present invention includes a cationic surfactant introduced with a glyceryl group represented by Formula 1 as a base for enhancing coacetate formation.

Referring to Chemical Formula 1, the cationic surfactant used in the present invention is a structure of a quaternary ammonium compound, one of substituents of ammonium ions essentially consisting of an alkylamidopropyl group, and the other is a repeating unit with a hydrophilic group. Glyceryl group having 1 to 11 is condensed and repeated structure, the remaining two substituents are composed of a methyl group.

The quaternary ammonium cationic surfactant contains at least one glyceryl group, which is a hydrophilic group, and is soluble in an aqueous solution called a pseudo-nonionic complex surfactant through interaction with an anionic surfactant. Mixed micelles can be formed. These pseudo-nonionic composite surfactants improve the problems of high viscosity and precipitation that occur when styling polymers (or styling polymers and silicone elastomers) and anionic surfactants are used at the same time, and therefore, in the presence of anionic surfactants. It is also possible to increase the amount of coacervate formed by increasing the amount of the styling polymer (and silicone elastomer).

In addition, the quaternary ammonium cationic surfactant of Formula 1 includes an alkylamido group having a relatively hydrophilic property instead of a long chain fatty acid group, so that the mixed micelle formation ability of a pseudo-nonionic complex surfactant is better. In the presence of anionic surfactants, the amount of styling polymer used may be further increased, resulting in a special function of producing more coacervates, which are complexes of anionic surfactants and styling polymers and / or silicone elastomers.

The quaternary ammonium cationic surfactant is preferably used in an amount of 0.1 to 10% by weight based on the total weight of the composition. If the content is less than 0.1% by weight, it is difficult to achieve coacervate formation and stability improvement effect by the quaternary ammonium cation surfactant, and when the content is more than 10% by weight, the hair becomes damp and there is a concern about precipitation and phase stability.

If the content of the styling polymer is less than 0.01% by weight, the styling effect may be insignificant. If the content of the styling polymer is more than 10% by weight, the usability may worsen and precipitation may occur.

More preferably, the present invention provides a shampoo composition comprising an anionic surfactant, a styling polymer, a quaternary ammonium cationic surfactant represented by Formula 1, and a silicone elastomer. When the silicone elastomer is included in the styling shampoo composition containing the anionic surfactant, the styling polymer, and the quaternary ammonium cationic surfactant of Formula 1, the amount of coacetate is increased, thereby improving the styling effect. .
