Abstract
A creamy composition in the form of an oil-in-water emulsion comprising an oily phase dispersed in an aqueous phase, characterized in that it contains at least one anionic emulsifier which is liquid at room temperature, and at least 5% by weight of one or more waxes relative to the total weight of the composition, and in that the oily phase is in the form of a soft paste at room temperature. The anionic emulsifier is preferably a surfactant containing a phosphate group, such as octyldecyl phosphate. The present invention also relates to the uses of the said composition in cosmetics and dermatology, in particular for caring for, treating and/or making up the skin and/or mucous membranes, and more particularly for treating wrinkles and/or fine lines of the skin and/or for treating dry skin. The invention also relates to a process for preparing this composition, characterized in that at least one step of the process is carried out using a mixer-extruder.
