Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention The present invention provides hair that has an excellent softening effect on damaged hair and can significantly improve the moisturizing properties of damaged hair. The present invention relates to cosmetic compositions.

In recent years, people's awareness of fashion has increased, and as a result, women's hair styles in particular have become more fashionable. For this reason, the use of hair perms, hair coloring, hair dryers, etc. is becoming more frequent.

Consumer surveys have also shown that the ends of the hair become dry due to the water retention properties of the hair, making it difficult to brush the hair smoothly. Hair perms and hair coloring process hair chemically, so they have the effect of breaking the molecular bonds that make up the hair and weakening it. When exposed to water, the hair is physically damaged and the water retention capacity of the hair itself is reduced. Hair is physiologically dead tissue.

Therefore, once chemically damaged hair is not restored, the ends of the hair become dry.

Research has been conducted on hair cosmetics that improve the dryness of hair ends.

For example, Special Publication No. 40-6119 and Special Publication No. 45-
Publication No. 19639 describes a hair cosmetic containing a quaternary ammonium salt having a di- or tri-long chain alkyl group. This hair cosmetic imparts flexibility and smoothness to the hair, makes the hair easy to comb, and makes the hair supple, and also prevents the hair from being electrostatically charged.

However, the dryness of one hair is still far from satisfying consumer demands.

Further, JP-A-52-47923 describes a hair cosmetic composition comprising a diol derivative and methylpolysiloxane. This hair cosmetic exhibits excellent brushing properties.

However, no effect was observed on the dryness of the ends of one hair.

Further, JP-A-52-66638 describes a hair conditioning composition comprising polyethylene glycol, polyoxyethylene sorbitan monolaurate and corn oil. This composition has the effect of imparting luster and suppleness to the hair, but similarly does not have the effect of improving the dryness of the ends of the hair.

As described above, there is currently no hair cosmetic that is fully satisfactory for improving the dryness of the ends of damaged hair.

An object of the present invention is to provide a hair cosmetic composition that can impart a softening effect to damaged hair and improve the moisturizing properties of damaged hair.

The hair cosmetic composition of the present invention is characterized by containing the following components (a), (b), and (c).

(a) Cationic surfactant.

(b) Protein derivatives.

(c) Polysaccharide.

Examples of the cationic surfactant as component (a) include quaternary ammonium salts represented by the following general formula (1) and amino acid-based cationic surfactants.

(Each symbol in the formula represents the following.

R: Alkyl group having 10 to 24 carbon atoms.

- 24 hydroxyalkyl group, R2 (○CH2CH2+ 5], benzyl group or cinnamyl group R1, R4: alkyl group having 1 to 3 carbon atoms, ε y is the same as above], benzyl group or cinnamyl group X: halogen atom or alkyl sulfate group having 1 to 2 carbon atoms) Typical quaternary ammonium salts represented by general formula (I) include stearyltrimethylammonium chloride and distearyldimethylammonium chloride.

Representative examples of amino acid-based cationic surfactants include mono-N-long chain acyl basic amino acid lower alkyl ester salts.

In addition, the polypeptide as a raw material has a molecular weight of 200 to 2
000 is preferred. The molecular weight of the polypeptide is 20
If the molecular weight is less than 0, the setting properties (clumpability) of the hair may be poor, and if the molecular weight exceeds 2000, the hair may become stiff.

The blending amount of the protein derivative is 0.05 to 5 weight percent, preferably 0.05 to 5 percent, based on the entire hair cosmetic composition.
．． It is 1 to 3% by weight.

(c) As the multi-NM component, Acinetobacter species (
