Abstract
A non-aqueous silicone emulsion is provided. It comprises a continuous phase of a polar organic liquid containing droplets of an organopolysiloxane dispersed therein. An organic wax, which has a melting point in the range 40 to 100° C. and is sparingly soluble in the polar organic liquid at 25° C., is dispersed in the polar organic liquid continuous phase as a network of interconnected particles which stabilizes the organopolysiloxane droplets in emulsion in the polar organic liquid. A process for the production of the emulsion is also disclosed.
