ABSTRACT:
The present invention relates to cosmetic or dermatological compositions in the form of an ultrafine oil-in-water emulsion wherein the mean size of the particles or globules which form the fatty phase ranges from 50 nm to 1000 nm, and wherein the composition also contains at least one crosslinked poly(2-acrylamido-2-methylpropanesulphonic acid) polymer neutralized to at least 90%. These compositions may be obtained according to an emulsifying technique using phase inversion. These compositions are stable in all viscosity ranges with a large variety of possible emulsifiers and whatever oils are employed. They can contain a large variety of cosmetic active substances and adjuvants without disturbing their stability and they can be employed in many cosmetic and dermatological applications and adapted to all types of skin.
