Abstract

PURPOSE: To prepare a composition capable of preventing the deterioration of mechanical properties of hair caused by attack with atmospheric air and especially with light by compounding 2-hydroxy-4-methoxybenzophenone-5- sulfonic acid or its salt. CONSTITUTION: This composition is obtained by compounding 2-hydroxy-4- methoxybenzophenone-5-sulfonic acid or its salt (e.g. a salt formed with a metal oxide, ammonia water or an amine) in an aqueous, alcoholic or alcoholic aqueous medium in an amount of at least 0.3wt.%, preferably 0.3-9wt.%. The compounding ratio (in terms of free acid) of the compound is preferably 0.3-3.5wt.% in cases where the composition is not rinsed and 0.5-6wt.% in cases where it is rinsed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and its salts as an agent for protecting the keratin of hair from atmospheric attack and especially from light rays. and to protect the hair from atmospheric attack and especially from light rays.

It has long been known that light rays attack keratin. Many publications have disclosed that natural light reduces the mechanical properties of hair by destroying certain amino acids in hair and denaturing hair M fibers, and the reduction of mechanical properties is defined as stretching. It mainly refers to the reduction in Dalier at a rate of 15%.

Variance at a 15% stretch rate refers to the weight that must be applied to a given length of wet hair to stretch the length by 15%. The greater the weight, the higher the elasticity and durability of the hair.

ahau [! In order to prevent the invasion of the keratinous substance of the hair by the light rays, it has already been proposed to use substances that are capable of filtering the light rays. In particular, benzophenone derivatives, such as 2-hydroxy-4-methoxybenzophenone and 2,2'-dihydroxy-4,4'-dimethoxy-5,5'-disulfobenzophenone disodium or dibenzoylmethane derivatives, such as 4-tertiary -butyl-41-methoxydibenzoylmethane or p-aminobenzoic acid and its derivatives such as 2-ethylhexyl p-dimethylaminobenzoate, (4'-dimedylaminobenzoyloxyethyl)dimethylalkyl (C1
6-Cl8) Ammonium tosylate (ESCALO
L 537G), cinnamates such as 2-ethylhexyl p-methoxycinnamate, or filtering agents known in the art such as 2-phenylbenzimidazole-5-sulfonic acid have been tried.

However, it has been found that these filtering substances are not effective in preserving the mechanical properties of the hair, ie its elasticity, against the harmful effects of light radiation.

Rather, the presence of these photogenic substances in certain cosmetic compositions appears to lead to a noticeable decrease in mechanical properties, especially at 15% stretch.

The present inventor intends to use r UVINUL H3 by BASF.
It has been found that 2-hydroxy-4-methoxybensif-1non-5-sulfonic acid and its salts, sold under the name 40J (7), can prevent the deterioration of the mechanical properties of hair caused by light rays. This characteristic is due to exposure to natural light (sunny environment)
and exposure to artificial light (5UNTESTII A HA
This could be confirmed using the xenon light emitting device of the U-type accelerated aging test device.

The present invention therefore provides 2-hydroxy-4 as an agent to preserve the mechanical properties of the hair, in particular the parier at N11 and a draw ratio of 15%, against deterioration caused by atmospheric attack and in particular by light radiation. -methoxybenzophenone-5-sulfonic acid or a salt thereof.
