Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition which imparts excellent gloss to the hair, provides a smooth feel to the hair, and is excellent in the effect of spreading the curly hair.

[0002]

2. Description of the Related Art Conventional hair cosmetics contain an oil component such as silicone oil, ester oil or hydrocarbon oil for the purpose of imparting luster and smoothness to the hair and extending the curly hair. It was used after being solubilized, emulsified or dissolved. In particular, silicone oil has been widely used in recent years because it has a low surface tension, is excellent in familiarity with hair, and has good gloss. Further, cationic surfactants are often used for the purpose of imparting smoothness. However, if a large amount of oil is used for a long time to achieve the above purpose, or if it is used for a long period of time, it has the drawback that the hair becomes greasy, and the cationic surfactant does not give the desired luster, and a large amount of the compound is safe. There was a disadvantage that it was not preferable. In addition, it cannot be said that these conventional oils alone have a sufficient curling effect.

The present inventors have taken these problems into consideration.
As a result of earnest research to provide hair cosmetics with excellent luster, smooth feel, and smoothing effect of curly hair, amphoteric surfactants and / or semipolar surfactants and higher fatty acids It has been found that the above object can be achieved by incorporating a composite obtained by mixing and a specific polyvinylpyrrolidone-based polymer, and the present invention has been completed based on this finding.

Most preferred are alkyl groups or alkenyl groups of 13 to 13. If the average number of carbon atoms is less than 9, the hydrophilicity is too strong and it is difficult to form a complex. On the other hand, if the average number of carbon atoms exceeds 21, the solubility in water is poor and the complex is difficult to form. R ² represents an alkyl group or an alkenyl group having an average of 10 to 18 carbon atoms. x is an integer of 2 to 4, y is an integer of 0 to 3, and z is an integer of 1 or 2. In the present invention, any one or more of these amphoteric surfactants and / or semipolar surfactants are selected and used.

The higher fatty acids used in the present invention include
For example, a higher fatty acid represented by the general formula R ³ COOH,
All of the higher fatty acids used in ordinary cosmetic bases and the like can be applied. Here, R ³ is an average of 7 carbon atoms
A saturated or unsaturated hydrocarbon having a linear or branched chain or a hydroxyl group of 25 to 25, a saturated or unsaturated hydrocarbon having a linear or branched chain or a hydroxyl group of an average of 9 to 23 carbon atoms is more preferable, and an average carbon Most preferred is a saturated or unsaturated hydrocarbon having a linear or branched chain having 11 to 21 atoms or a hydroxyl group. If the average number of carbon atoms is less than 7, the hydrophilicity is too strong and it is difficult to form a complex. On the other hand, the average number of carbon atoms is 2
When it exceeds 5, the melting point becomes high and it is difficult to form a composite. Specific examples of higher fatty acids include saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid and behenic acid, 2-palmitoleic acid, petroselinic acid, oleic acid, elaidic acid, ricinoleic acid and linoleic acid. Examples thereof include unsaturated fatty acids such as acids, linoelaidic acid, linolenic acid, and arachidonic acid, branched fatty acids such as isostearic acid, and hydroxycarboxylic acids such as 12-hydroxystearic acid. In the present invention, any one or more of these higher fatty acids are selected and used.

Amphoteric surfactant and / or used in the present invention
Alternatively, a complex obtained by mixing a semipolar surfactant and a higher fatty acid is one in which the amphoteric surfactant and / or the semipolar surfactant is bound at the carboxyl group portion of the higher fatty acid and is an excellent emulsifier. For details, see Japanese Patent Application No. 3-16
No. 6367. In the present invention, the compounding ratio of the higher fatty acid and the amphoteric surfactant and / or semipolar surfactant in the complex is such that the weight ratio of the former to the latter is preferably 0.5: 9.5 to 9.5: 0.5 {(higher fatty acid) / (amphoteric surfactant and / or semipolar surfactant)
= 0.05-19}, more preferably 1: 9-9: 1
From the viewpoint of stability, it is preferable that {(higher fatty acid) / (amphoteric surfactant and / or semipolar surfactant) = 0.1-9}. Further, the total amount of the amphoteric surfactant and / or semipolar surfactant and the higher fatty acid is preferably 0.1 to 30% by weight from the viewpoint of stability, and 0.5 to 2
It is more preferably 0% by weight.
