Hair cosmetic composition

Abstract

Disclosed is a hair cosmetic composition containing (a) a tertiary amine represented by general formula (1), (b) a pyrrolidone carboxylate, and (c) a higher alcohol. In the formula, R5 represents an alkyl group having 8-30 carbon atoms; -A- represents an amide group or an ether group; m represents 0 or 1; when -A- is an amide group, R6 represents an alkylene group having 2-4 carbon atoms or a hydroxyalkylene group; when -A- is an ether group R6 represents an alkylene group having 2-4 carbon atoms; R7 represents a linear or branched alkyl or alkenyl group having 8-30 carbon atoms, which may be interrupted by an amide group or an ether group, or a linear or branched alkyl or hydroxyalkyl group having 1-3 carbon atoms; and R8 represents a linear or branched alkyl or hydroxyalkyl group having 1-3 carbon atoms.

Description

technical field The present invention relates to hair cosmetics. Background technique For hair cosmetics such as shampoo, rinse, hair conditioner, hair conditioner, hair dye, mousse, etc., it is required to protect the hair and improve the touch while using it. , impart softness, smoothness, and oily feeling to hair, and impart smoothness, good combability, and soft touch to hair after drying. Due to such demands, various quaternary ammonium salts or amine salts have been blended as cationic surfactants in conventional hair cosmetics. As the counterion of these salts, the use of Cl was reported - Halogen ions such as (Patent Document 1), or short-chain alkyl sulfate ions such as methylsulfuric acid and ethylsulfuric acid, acetic acid, tartaric acid, fumaric acid, lactic acid, malic acid, succinic acid, and carboxylic acids with long-chain alkyl groups and Technology of organic acid ions such as sulfonic acid (Patent Documents 2 and 3). However, it is not possible to ful...

AI Technical Summary

Problems solved by technology

However, the two aspects of the feeling of use when applying it to the hair and washing, and the improvement of the hair quality after drying cannot be fully satisfied at the same time.

In addition, although it has been proposed that a specific etheramine compound and an organic acid can be used together to improve the conditioning effect (Patent Documents 4, 5, 6, and 7), it is still expected to further improve the touch during use and improve the hair quality after washing.
