    Abstract: A composition in the form of an oil-in-water emulsion comprising, in a physiologically acceptable medium, an oily phase dispersed in an aqueous phase and comprising at least one acrylic terpolymer obtained from the polymerization of a carboxylic acid monomer having &agr;,&bgr;-ethylenic unsaturation, a non-surface-active monomer comprising ethylenic unsaturation other than (a), and a non-ionic urethane monomer which is the reaction product of a monohydric non-ionic amphiphilic compound with an isocyanate comprising monoethylenic unsaturation, in which the terpolymer/oily phase ratio by weight ranges from 1/50 to 1/125. The composition is particularly suited for cosmetic and/or dermatological applications.

    Abstract: The present invention relates to a stable fluid water-in-oil emulsion, in particular a topical emulsion, comprising, as gelling agent, a polysaccharide alkyl ether formed from units containing at least two different monosaccharide rings, each unit containing at least one hydroxyl group substituted by a saturated hydrocarbon alkyl chain. The polysaccharide alkyl ether preferably has a weight average molecular weight greater than 200,000 and preferably is a guar gum alkyl ether having a degree of substitution of approximately 2 to 3. The emulsion obtained is stable, even in the absence of an electrolyte or a fatty substance commonly used to stabilize water-in-oil emulsions. It can in particular contain an active ingredient sensitive to electrolytes. The emulsion according to the invention can be used in particular in the cosmetics and/or dermatological fields.
