摘要:
The present invention provides a method for the easy preparation of a mixture comprising betaine alkyl ester which gives good softness, smoothness and oily feeling to hair. Thus, according to the present invention, a specific monohalogen carboxylic acid alkyl-ester is made to react with a specific tertiary amine using a specific long-chain alcohol as a reaction solvent and, after a specific betaine alkyl ester is obtained, the excessive above-mentioned tertiary amine is removed whereupon a mixture comprising the said long-chain alcohol and the said betaine alkyl ester is obtained.
