JP7335593B2 - Hair cleanser composition - Google Patents

Description

The present invention relates to a hair cleansing composition.

Alkyl sulfates, alkyl ether sulfates, and the like are conventionally used as anionic surfactants that are excellent in foaming and detergency in hair cleansing agents. However, since these ingredients may reduce the hair conditioning effect, they are used in hair cleansing agents in combination with amino acid-based anionic surfactants or amphoteric surfactants, which are milder on hair.

Moreover, in recent years, in order to further enhance the conditioning effect on hair, attempts have been made to blend cationic surfactants and oils such as silicones. However, in order to obtain a high conditioning effect, it is necessary to add a large amount of oil agents such as cationic surfactants and silicones. there were.

Patent Document 1 proposes a hair cleanser composition that foams quickly, produces creamy foam that is easy to pass through fingers during rinsing, has excellent conditioning properties, and foams well even when hair is washed using hair wax. there is
