Description

Washing and conditioning composition for keratin materials comprising a particular oxidized polysaccharide, use and process

The present invention relates to a composition for washing and conditioning keratinous substances, in particular keratinous fibers, comprising at least one anionic surfactant and at least one particular oxidized polysaccharide, the use of said composition for washing and conditioning keratin materials , in particular keratinous fibers, as well as a method for implementing said composition.

For washing and / or washing the hair, the use of detergent hair compositions (or shampoos) based essentially on conventional surfactants including anionic, nonionic and / or amphoteric, but more particularly anionic, is common. These compositions are applied to wet hair and the foam generated by massage or friction with the hands allows, after rinsing with water, the elimination of various soils initially present on the hair.

Although these basic compositions have a good washing power, the intrinsic cosmetic properties attached to them remain rather weak, in particular because the relatively aggressive nature of such a cleaning treatment can lead in the long run to the fiber. capillary damage more or less marked especially related to the progressive elimination of lipids or proteins contained in or on the surface of the latter.

Also, to improve the cosmetic properties of the above detergent compositions, and more particularly those that are to be applied to hair sensitized (ie hair that is damaged or weakened especially under the chemical action of atmospheric agents and / or hair treatments such as permanent, dyes or discolorations), it is now customary to introduce into the latter complementary cosmetic agents known as conditioning agents intended primarily to repair or limit the harmful or undesirable effects induced by the various treatments or aggressions that undergo , more or less repeated, the hair fibers. These conditioning agents can of course also improve the cosmetic behavior of natural hair.

The most commonly used conditioning agents in shampoos today are cationic polymers, silicones and / or silicone derivatives, which in effect give washed, dry or wet hair a considerably easier disentangling and softening effect. compared to what can be achieved with the corresponding cleaning compositions which are free of it.

However, the cosmetic benefits mentioned above are unfortunately also accompanied, on dried hair, certain cosmetic effects deemed undesirable, namely including a heavier hair, a lack of smoothing.

In addition, the use of cationic polymers for this purpose has various disadvantages. Because of their high affinity for the hair, some of these polymers, in particular cationic starches, deposit significantly during repeated uses, and lead to undesirable effects such as unpleasant, loaded, stiffening of the hair. , and interfiber adhesion affecting styling. In addition, dried hair is often rough, unruly and lacks shine. These disadvantages are accentuated in the case of fine hair, which lack of nervousness and volume.

On the other hand, polymers comprising cationic groups may have incompatibility problems with anionic surfactants.

In summary, it turns out that the current cosmetic compositions containing conditioning agents, are not completely satisfactory.

So that a strong need still exists today to be able to have new non-cationic conditioning agents having good cosmetic properties without the disadvantages mentioned above.

The present invention aims to satisfy such a need.

Thus, following important research conducted on the subject, it has now been found by the Applicant, in a totally unexpected and surprising manner, that using a washing composition comprising in a cosmetically acceptable medium, from 5 to 50% by weight relative to the total weight of the composition of one or more detergent surfactants and one or more particular oxidized polysaccharides, it is possible to obtain detergent compositions having excellent cosmetic properties such as an excellent conditioning effect, in particular softness, nervousness, smoothing and disentangling of treated hair. Moreover, the hair is not loaded, they have a natural and clean touch.

All these discoveries are at the basis of the present invention.

Thus, according to the present invention, it is now proposed new washing compositions including capillary comprising, in a cosmetically acceptable medium, from 5 to 50% by weight relative to the total weight of the composition of one or more detergent surfactants and a or several oxidized anionic or nonionic polysaccharides consisting of monosaccharides comprising 5 carbon atoms or more than 5 carbon atoms, preferably 6 or more carbon atoms and more particularly 6 carbon atoms.

A second object of the invention is the use of such a polysaccharide oxidized in cosmetics, as a hair conditioning agent.

Among these methods, one of the preferred ones is that described in application FR2842200. In this process, a glucose unit polysaccharide is subjected to the action of peroxide in the presence of a phthalocyanine-metal catalyst complex.

The amount of catalyst depends on the degree of substitution desired. In general a small amount, for example, an amount corresponding to 0.003 to 0.016 molar equivalents per 100 glucose units of polysaccharide is suitable.

The temperature of the reaction is generally between 20 ° C. and 90 ° C.

The temperature range between 45 ° C and 60 ° C and particularly preferred.
