Description

The present invention relates to a cosmetic composition, in particular a capillary composition, that can be used to bring about a permanent change to keratinous materials, a process which can be used to provide a residual change in keratin materials. treatment using said composition. In the hair field, consumers want to have compositions to make a temporary change to their hair, and aiming for a good performance of the effect achieved. In general, it is desired that the change persists shampoos for at least 15 days, or more depending on the nature of the change.

Treatments already exist to change the color or shape of the hair and, to a certain extent, the texture of the hair. One of the known treatments for modifying the texture of the hair consists of the combination of heat and a composition comprising formalin. This treatment is especially effective to give a better appearance to damaged hair, and / or to treat long hair and curly hair. The action of formalin is associated with its ability to crosslink proteins by reaction on its nucleophilic sites. The heat used can be that of iron (flat tongs or curling tongs), whose temperature can generally reach 200 ° C or more.

However, it is increasingly sought to avoid the use of such substances, which can be aggressive for the hair and other keratin materials. It has thus been proposed, by the application WO2011 / 104282, a new method for semi-permanently smoothing the hair, consisting in applying a solution of alphaketoacid on the hair for 15 to 120 minutes, then drying and finally smoothing iron, at a temperature of about 200 ° C, the hair. The alpha-ketoacid used is preferably glyoxylic acid. However, it has been found that the use of glyoxylic acid may give rise to some important limitations; in particular, its pH of action is acid, in particular of the order of 4, or even lower, which may not always be well tolerated, especially when the scalp is sensitive and / or irritated. Nor is it desirable to use it in high concentrations because of its intrinsic acidity. Its volatility, amplified by the use of heat (iron), can also be a problem. In addition, cosmetic formulations with acidic pH can alter the hair and / or alter the color. However, the treatment sought is particularly intended to provide repair artificially colored hair. It is therefore preferred to avoid the use of assets that can provide a reinforcing effect but by contributing to alter the hair and / or their artificial color. It is already known to use glyoxylic acid esters in hair compositions, in particular in hair dyeing compositions as described in DE19859722 and in reducing compositions as described in DE19860239. Now, the Applicant has now discovered, unexpectedly and surprisingly, that certain specific compounds make it possible to provide the desired properties to keratin materials. In particular, the composition according to the invention will not cause a change in the color of the hair, and will not cause hair breakage problem. The composition will not alter the integrity of the fiber, especially its cuticle. It will further improve the mechanical properties of the hair, such as moisture resistance and shine, and reduce the effects of frizz.
