USE OF 2-HYDROXY-4-METHOXYBENZOPHENONE-5-SULFONIC ACID OR ITS SALTS FOR HAIR PROTECTION AGAINST ATMOSPHERIC AGGRESSIONS, ESPECIALLY AGAINST LIGHT, AND HAIR PROTECTION METHOD USING THE SAME

摘要

P Use to preserve the mechanical properties of hair from degradation by atmospheric aggression, and particularly by light, of at least 0.3% by weight of 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid in an aqueous, alcoholic or aqueous-alcoholic carrier, cosmetically acceptable. The acid is optionally salified with a metal hydroxide, ammonia or an amine. The invention also relates to a method of protecting hair from keratin against light, comprising applying to the hair at least 30 mg / g of hair of a cosmetic composition containing at least 0.3% by weight of 2-hydroxy-4- acid methoxybenzophenone-5-sulfonic acid. / P
