The invention concerns an emulsion comprising an oily phase dispersed in an aqueous phase, characterised in that the oily phase globules have an average size less than 20 microns, the oily phase constitutes at least 15 wt. % relative to the emulsion total weight and the aqueous phase contains at least a copolymer consisting of a majority fraction of C3-C6 carboxylic acid monomer with mono-olefin unsaturation or its anhydride and a minority fraction of an acrylic acid fatty chain ester monomer, and is surfactant-free. The invention also concerns the use of said emulsion in cosmetics and/or dermatology, in particular for the treatment, protection, care and/or cleaning of the skin, mucous membranes and/or hair, and/or as make-up for the skin and/or mucous membranes. The invention further concerns a method for preparing said emulsion, which consists in introducing under pressure the oily phase into the aqueous phase containing the copolymer, through a porous hydrophilic glass membrane having an average pore size ranging from 0.1 to 5 mu m and preferably from 0.3 to 3 mu m, under pressure higher than critical pressure. |
