Abstract
Disclosed are personal care compositions which are suitable for application to the hair, skin, or nails. These compositions comprise a polyorganosiloxane emulsion comprising a surfactant and a polyorganosiloxane having an average particle size of less than about 150 nanometers; from about 0.01% to about 10% of a silicone-linear polyoxyalkylene block copolymer surfactant; and a carrier comprising (i) at least about 0.5%, by weight of the composition, of a first solvent selected from the group consisting of water, water soluble organic solvents, organic solvents which are strongly to moderately strong in hydrogen-bonding parameter, and mixtures thereof, wherein the solvent is other than a C.sub.1 -C.sub.3 monohydric alcohol, a C.sub.1 -C.sub.3 ketone, and a C.sub.1 -C.sub.3 ether, and (ii) at least about 40%, by weight of the composition, of a second solvent selected from the group consisting of C.sub.1 -C.sub.3 monohydric alcohols, C.sub.1 -C.sub.3 ketones, C.sub.1 -C.sub.3 ethers, and mixtures thereof. The silicone-polyoxyalkylene copolymer surfactant provides for improved stability of the polyorganosiloxane emulsion, especially when lower alcohols such as C.sub.1 -C.sub.3 monohydric alcohols are incorporated into the compositions.
