Definitions

• the subject of the present invention is a cosmetic composition, in particular for topical application, consisting of two distinct phases, an aqueous phase and a water-in-oil (W / O) or oil-in-water (O / W) emulsion phase.

• compositions consisting of two distinct phases, in particular an aqueous phase and a phase comprising oily compounds, said phases being distinct and not emulsified one in the other at rest, are generally referred to as "two-phase compositions ". They are distinguished from emulsions by the fact that at rest, the two phases are distinct, instead of being emulsified one in the other.
• the use of these two-phase compositions requires prior agitation to form an emulsion, the latter must be of sufficient quality and stability to allow a uniform application of the two phases on the skin or the keratin material where it is applied. At rest, said phases must separate quickly and return to their initial state, this phenomenon being better known as "phase shift".
• a rapid phase shift (or demixing) of the two phases after their use is one of the desired qualities of two-phase compositions. Indeed, obtaining a rapid phase shift is desirable for various reasons, in particular because a poor separation of the two phases is perceived as unsightly by users. However, it has proved difficult to find phase shift agents which make it possible to obtain a good phase shift without the formation of foam in the oily phase of the biphase during stirring. However, this formation of foam is prohibitive for the user. In addition, with conventional two-phase compositions, an emulsion is not necessarily formed after stirring the composition, which results in unsatisfactory makeup removal, and leaves a greasy residue on the skin or the keratin material.
• the Applicant has developed a two-phase formulation having the desired qualities, that is to say, separating rapidly in two clear phases after use, without there being foaming in the oily phase. during agitation.
