Abstract
Abstract Water-in-oil emulsions usefully employed in the preparation of cosmetics for the skin comprise a discontinuous aqueous internal phase, a continuous oil external phase, and as an emulsifying agent a compound having the formula RO-C2H3O(R'')-C2H3O(CH2OH)-H wherein R is alkyl having 16-18 carbon atoms or the residue of hydrogenated lanolin alcohol, R'' is methyl or ethyl, m is 3-5 and n is 2-3. The emulsion also contains a polymeric emulsion stabilization agent or a magnesium salt thereof, or magnesium isostearate.
