Abstract
A water-in-oil (W/O) emulsion with a discontinuous aqueous phase dispersed in a continuous oil phase has in the continuous oil phase a linear silicone polyether, an α,ω-diene crosslinked silicone elastomer, and a nonionic organic emulsifier. The W/O emulsion is otherwise free of silicone elastomers prepared using unsaturated compounds containing silicon atoms. Either the discontinuous aqueous phase of the W/O emulsion or the continuous oil phase of the W/O emulsion contains a water soluble or oil soluble active ingredient such as a vitamin.
