Abstract
Natural bristles (animal hairs) are submerged in a solution containing at least one or more kinds of cationic surfactants selected from alkyl ammonium salts containing a quaternary nitrogen or alkylbenzyl ammonium salts containing a quaternary nitrogen, and alkylpyridinium salts to adsorb the cationic surfactants onto the natural bristles in an amount of 0.2-5% by weight by treating with heat, and a hair brush is produced using these natural bristles.
Claims8
A cosmetic brush having wash-and-rub-durable antimicrobial and deodorant properties, comprising natural animal hair bristles to which at least one or more kinds of cationic surfactants selected from alkyl ammonium salts containing a quaternary nitrogen or alkylbenzyl ammonium salts containing a quaternary nitrogen, and alkyl pyridinium salts in an amount of 0.2-5% by weight are adhered by heat solution adsorption.
A method of producing a cosmetic brush having wash-and-rub-durable antimicrobial and deodorant properties, characterized in that natural bristles are submerged into an aqueous solution containing at least one or more kinds of cationic surfactants selected from alkyl ammonium salts containing a quaternary nitrogen or alkylbenzyl ammonium salts containing a quaternary nitrogen, and alkyl pyridinium salts, said cationic surfactants in an amount of 0.2-5% by weight are adhered onto the natural bristles by adsorption with heating, and then the resulting natural bristles are used for the cosmetic brush.
