L'invention concerne également un procédé de traitement cosmétique des fibres kératiniques, notamment de lavage et/ou de conditionnement des cheveux, à l'aide d'une telle composition, ainsi qu'une utilisation mettant en œuvre ladite composition.The present invention relates to a composition intended for the cosmetic treatment of keratin fibers, in particular the hair, comprising at least two anionic surfactants, at least one nonionic surfactant, at least one amphoteric surfactant, and at least one organosilane. The invention also relates to a process for the cosmetic treatment of keratin fibers, in particular for washing and / or conditioning the hair, using such a composition, as well as a use using said composition.

Description

The present invention relates to a composition for the cosmetic treatment of keratinous fibers, in particular human keratinous fibers such as the hair, comprising at least two distinct anionic surfactants, at least one nonionic surfactant, at least one amphoteric surfactant, and at least one organosilane. The invention also relates to a process for the cosmetic treatment of keratin fibers using such a composition, as well as a use implementing said composition.

It is often common to use caring and / or washing compositions of keratin fibers using complementary cosmetic agents known as conditioning agents in order to improve the cosmetic properties of sensitized hair. These conditioning agents can of course also improve the cosmetic behavior of natural hair.

However, these hair compositions do not necessarily give complete satisfaction and can still be improved, especially concerning the deposition of conditioning agents on keratinous fibers.

Moreover, the hair compositions of the prior art generally do not give complete satisfaction in terms of mass (or body) delivery to the hair, qualities of use (spreading and distribution of the composition, easy rinsing), and in terms of persistence to different external agents (eg shampoos, light, pollution).

There is therefore a real need to develop hair compositions intended for cleaning and conditioning keratinous fibers which are capable of imparting improved cosmetic properties to the hair, in particular a contribution of mass (or body supply), to the hair, after one or more applications, and this in a sustainable way; while maintaining a good washing power, including good foaming (abundant foam, quickly generated, good quality) and satisfactory use qualities (ease of spreading the composition on the hair particularly wet, good rinçabi-lité) , and this without charge or heavier hair.

This object is achieved by the present invention which has for object a cosmetic composition, preferably a capillary composition, especially intended for the cosmetic treatment of keratinous fibers, in particular human keratinous fibers such as the hair, comprising: (i) one or more surfactants anionic compounds selected from polynoxyalkylenated al-kyl (amido) ether carboxylic acids and their salts; (ii) one or more anionic surfactants different from the polioalkylenated alkyl (amido) ether carboxylic acid anionic surfactant (i); (iii) one or more nonionic surfactants; (iv) one or more amphoteric surfactants; and (v) one or more organosilanes.

It has been found that the composition according to the invention has satisfactory foaming power. It allows the production of an abundant foam, generated quickly, which spreads easily on keratinous fibers and which is easily removed by rinsing.

Some users of shampoos, in particular conditioners, may have hair that is more or less sensitized, that is to say hair that is generally damaged or weakened by the action of external atmospheric agents such as light and the elements, and / or or the action of mechanical or chemical treatments such as brushing, combing, dyeing, discoloration, perms and / or straightening. Also, the composition according to the invention also makes it possible to improve the cosmetic properties conferred on keratinous fibers, in particular on the hair, which are preferably sensitized. In particular, the composition according to the invention makes it possible to improve the body, the smoothing, the disentangling, the suppleness as well as the feel of the hair, without a build-up effect. Furthermore, the compositions according to the invention have a relatively low aggressive character, their application over time on the hair fiber resulting in little damage related in particular to the progressive elimination of lipids or proteins contained in or on the surface of the latter .

In addition, the composition according to the invention allows a good deposition of the organosilanes on the keratinous fibers and the scalp, and thus makes it possible to obtain an improved packaging.

In addition, the composition according to the invention can confer cosmetic properties that are remanent to shampoos.

The composition according to the invention also has the advantage of being storage stable both at room temperature (20-25 ° C) and at 45 ° C, especially in terms of its visual appearance and / or its viscosity.

By "stable" is meant in the sense of the present invention a composition which, after two months of storage shows no change in appearance, color, odor or viscosity.

Preferably, the composition according to the invention is non-coloring.

According to the present invention, the term "non-coloring composition" is intended to mean a composition which does not contain a dye for keratinous fibers such as direct dyes or oxidation dye precursors (bases and / or couplers). If they are present, their content does not exceed 0.005% by weight, relative to the total weight of the composition. Indeed, at such a content, only the composition would be tinted, that is to say, one would not observe staining effect of keratin fibers.

In what follows, and unless otherwise indicated, the boundaries of a domain of values are included in this field, especially in the expressions "between" and "from ... to ...".

Moreover, the expression "at least one" used in the present description is equivalent to the expression "one or more" and can be substituted for it.
