Abstract
A water-in-oil emulsion and a method of making the emulsion in which the emulsion includes 5 to 50 percent by weight of an organic oil; 44 to 94.5 percent by weight of water; and 0.5 to 5 percent by weight of a water dispersible silicone wax. The emulsion is free of organic emulsifying agents. The water dispersible silicone is a wax derived from the reaction of (i) an .ident.SiH containing siloxane; (ii) a linear C30+ organic alpha-olefin; and (iii) an unsaturated ethylene oxide polymer. Emulsions having a viscosity in about 150,000 centistokes to about 200,000 centistokes are described.
