Description

  The present invention relates to a hair cosmetic composition. More specifically, the present invention relates to a hair cosmetic composition that can effectively prevent specific problems when hyaluronic acids are blended in the hair cosmetic as a moisturizing component.

  As is well known, hyaluronic acid is a linear polymer mucopolysaccharide consisting of repeating disaccharide units in which glucuronic acid and N-acetylglucosamine are glycosidically linked, and having a molecular weight of about several hundred thousand to several million daltons. And distributed in each part of the living body. And since hyaluronic acid has the capability to couple | bond with a lot of water | moisture contents, it is often mix | blended with various hair cosmetics as a moisturizing component, for example.

[Patent Document 1] Japanese Patent Application Laid-Open No. S59-110612 Patent Document 1 discloses hyaluron as a hair treatment agent for hair treatment, hair conditioner, hair spray, set lotion and the like for the purpose of recovering damaged hair and giving gloss to hair. It discloses that an acid or a salt thereof is added.

Japanese Patent Laid-Open No. 1-221308 discloses a hair cosmetic comprising hyaluronic acid or a salt thereof, a cationic surfactant, and a nonionic or amphoteric surfactant. Hyaluronic acid Or it states that the salt can be expected to give moisturizing effect and moist feeling to the hair.

JP-T-2002-522570 gazette The above Patent Document 3 contains, as a “hyaluronic acid derivative”, a hyaluronic acid salt in which a certain amino acid is amide-bonded to a carboxyl group of glucuronic acid constituting hyaluronic acid, and this Cosmetic compositions and the like are disclosed. This document also describes the water retention capacity of hyaluronate.

  As described above, it is known that hyaluronic acids such as hyaluronic acid and salts or derivatives thereof are blended in hair cosmetics, and in that case, hyaluronic acids impart a moisturizing effect to hair.

  However, according to the study of the present inventor, when these hyaluronic acids are added to the hair cosmetic, it is possible to expect an excellent moisturizing effect, but on the other hand, it has been found that there is a problem that a hair bundle feeling is produced in the finished hair. did. “Feeling of hair bundles” refers to excessive cohesion between hairs when hand combs are passed through the hair, and the hairs are bundled in units of dozens of units along the part through which the hand combs are passed. It gives a streak-like appearance and feel. It is not preferable to produce a feeling of hair bundle after using the hair cosmetic.

  Therefore, the present invention, when blended with hyaluronic acid in hair cosmetics, ensures excellent moisturizing effect and secondary effects related to this (hair glossiness, etc.), and the hair bundle feeling in the finished hair. Preventing the occurrence of this is a technical problem to be solved.

  In the course of researching the means for solving the above problems, the inventor of the present application uses (1) a cationized hyaluronic acid having a specific structure, which is rare as hyaluronic acid to be blended for such purposes, and (2) The present inventors have found that the means of blending a specific silicone derivative with cationized hyaluronic acid is extremely effective and completed the present invention.

In cationized hyaluronic acid and its analogs, it is not always necessary to modify all of the carboxyl groups of the many glucuronic acids constituting the repeating unit (the modification rate is 100%). It is sufficient that the modification rate be higher than the level that can be regarded as “constituted”. Furthermore, the “quaternary ammonium-containing modifying group” means a modifying group having at least a portion having a structure of a quaternary ammonium compound and a functional group chemically bonded to a carboxyl group of glucuronic acid.

  When the hair cosmetic composition containing both the component (A) and the component (B) is applied to the hair as in the first invention, the excellent moisturizing effect peculiar to hyaluronic acids and secondary effects resulting therefrom In this way, it is possible to effectively prevent the occurrence of a bundle of hairs in the finished hair.

  The reason why such an effect can be ensured by the hair cosmetic composition of the first invention has not yet been clearly clarified, but hyaluronic acid in which component (A) is cationized by quaternary ammonium or its analogs. It is presumed that the point that the cationization modification site is a carboxyl group of glucuronic acid and the point that the component (B) is blended are important.

(Second invention)
The configuration of the second invention of the present application for solving the above-described problem is that the quaternary ammonium-containing modifying group in the component (A) according to the first invention is at least a bond between quaternary ammonium and the carboxyl group. It is a hair cosmetic composition which is an organic group provided with the provided hydroxyl group.

  In the quaternary ammonium-containing modifying group of the component (A) in the first invention, the type of the functional group chemically bonded to the carboxyl group of glucuronic acid is not particularly limited, and may be, for example, an amino group. As in the second invention, the functional group is more preferably a hydroxyl group.

As in the third aspect of the invention, the cationized hyaluronic acid has a repeating unit represented by the formula 2 and the cationized hyaluronic acid analog has a hydroxyl group of the cationized hyaluronic acid represented by the formula 2 And those in which the N-acetyl group is salt-formed or modified are particularly preferred.

(Fourth invention)
The constitution of the fourth invention of the present application for solving the above problem is that the component (B) according to any of the first to third inventions is an aminoethylaminopropylmethicone / dimethicone copolymer, aminopropyldimethicone, high polymerization The hair cosmetic composition is at least one selected from aminopropyl dimethicone, amodimethicone and dimethiconol.

  The type of component (B) is not particularly limited as long as it is dimethiconol and amino-modified silicone, but more preferably at least one selected from the silicone derivatives listed above.

  The hair cosmetic composition of the present invention has a hair bundle feeling at the finish that is unique when blended with hyaluronic acids while ensuring excellent moisturizing effect and hair gloss based on the blended cationized hyaluronic acid and its analogs. Can be prevented.
