Description

B11-1477EN 1 Cosmetic composition comprising a hydrophobically modified cellulose, a cationic surfactant and a branched fatty alcohol. The present invention relates to a composition for the cosmetic treatment of keratinous substances, in particular human keratinous fibers such as the hair, comprising one or more particular hydrophobically modified celluloses, one or more cationic surfactants and one or more branched fatty alcohols. The present invention also relates to a process for the cosmetic treatment of keratin materials using such a composition as well as a cosmetic use of said composition. In the hair cosmetic field, it is sought to treat keratin fibers subjected to various external aggressions. Indeed, these fibers can undergo assaults of various origins, such as mechanical aggression, for example related to disentangling or blow drying, or chemical aggression, for example following a coloring or a permanent. These attacks have repercussions on the qualities of the keratinous fiber and can induce a difficult disentangling at the time of the washing of the hair, on dry hair and / or wet hair as well as a degradation of the surface properties of the fibers, which become on the surface not smooth and irregular, especially when the hair is dry. There are care products that can limit these phenomena. These products contain, in general, one or more agents for conditioning keratinous fibers, such as cationic surfactants. However, while improving the cosmetic properties of the hair, these compounds, used in skincare products, are not environmentally friendly.

There is therefore a need to develop cosmetic compositions that do not comprise silicone, which are less ecotoxic or even non-ecotoxic, making it possible to condition the hair satisfactorily, or even better, compared to the compositions of the state of the art. . The Applicant has now discovered that, surprisingly, the combination of a particular hydrophobically modified cellulose with at least one cationic surfactant and at least one branched fatty alcohol makes it possible to achieve the objectives set out above. These particular celluloses are described in particular in international patent application WO 2006/065848. The subject of the present invention is therefore a cosmetic composition for cleaning the body or for conditioning the hair, comprising one or more hydrophobically modified celluloses having a content of hydrophobic group (s) (hydrophobization rate) greater than 0.6%. by weight, relative to the total weight of the hydrophobically modified cellulose, one or more cationic surfactants and one or more branched fatty alcohols.

This particular combination has proved particularly suitable for the care of the hair and allowed to improve their cosmetic properties, and in particular to bring a better shaping and more volume to the hair with a very good disentangling and very good properties. flexibility and shine.

In addition, these care compositions are more eco-friendly, that is to say less ecotoxic vis-à-vis the environment. The present invention also relates to a method of conditioning the hair or washing / cleaning the body, comprising applying to the keratin materials a composition according to the invention. In particular, the composition according to the invention may be rinsed or not, applied under the effect of heat or not, and associated or not with chemical and / or mechanical treatments of the hair.
