Stable water-in-oil emulsion for cosmetic or pharmaceutical use. This emulsion comprises a fatty phase in a proportion of 15 to 40% consisting of at least one silicone in a proportion of 15 to 40% by weight relative to the total weight of the emulsion, and an aqueous phase containing at least one electrolyte-insensitive aqueous gelling agent, the emulsifying agent of the said emulsion being an alkyl- or alkoxydimethicone copolyol of general formula: in which: X is a hydrogen atom or a C1-C16 alkyl, C1-C16 alkoxy or C1-C16 acyl, Y is a C8-C22 alkyl or C8-C22 alkoxy radical, n=0 to 200, m=1 to 40, q=1 to 100, the molecular weight of the residue (C2H4O-)x(C3H6O-)y-X being from 250 to 2000, and x and y being chosen in such a way that the weight ratio of oxyethylene to oxypropylene groups is between 100:0 and 20:80. Production of stable emulsions having excellent cosmetic properties.
