Description

The present invention relates to a cosmetic composition comprising a fatty phase and a water phase that are distinctly different, the aqueous phase comprising at least one aqueous phase thickening agent and the fatty phase comprising at least one oil. , and to a hair treatment method comprisingapplying the composition. In the field of styling, in particular among hair products intended for shaping and / or maintaining the hairstyle, the hair compositions generally being in the form of gels, lotions, foams or hair spray. . In particular, the hair gels allow a good maintenance of the hair. Nevertheless, many hair gels do not provide enough hair cosmetics and the final result lacks naturalness. In addition, most hair gels have a homogeneous appearance that is not very attractive. It has already been proposed to produce compositions comprising visually distinct phases, as described for example in patent applications WO2006 / 093742, WO2006 / 042179, WO2006 / 010090, or WO2007 / 004200. In practice, the weight ratio between the different phases can generally only vary within a limited range of values and the preparation of these compositions is often difficult for a stability of the compositions obtained which is not entirely satisfactory. Hair care products often use conditioning agents, especially oils. Anhydrous compositions containing oils very often lead to a touch too greasy hair. In aqueous compositions, it is very often limited by the very low solubility of the oils in water generally requiring the use of surfactants in the aqueous compositions containing these oils, with often for ccrole a final emulsion-like final appearance. creamy. There is therefore a real need to find cosmetic compositions, which provide care for hair that allow easy formulation of oils in aqueous medium. There is also a need to find hair styling compositions which allow the hairstyle to be properly held while providing hair with cosmetics. There is also a need to find cosmetic compositions, especially for styling, which make it possible to obtain a hairstyle with a natural appearance, there is also a need to find cosmetic compositions which present a new and more attractive aesthetic appearance. The Applicant has discovered that the choice of an aqueous phase comprising at least one thickening agent of aqueous phase and a fatty phase comprising at least one oil in which the two phases are visually distinct made it possible to meet these needs. Thus, the subject of the present invention is a cosmetic cosmetic composition comprising: a fatty phase comprising at least one oil; an aqueous phase comprising at least one thickening agent of aqueous phase, the two phases being visually distinct. The present invention makes it possible to produce aesthetic compositions that provide care for the hair. It is thus possible to obtain a composition which comprises a relatively large quantity of oil.
