ABSTRACT:
A method for preparing oil-in-water emulsions of oils, gums or silicone resins by kneading a mixture of (1) a silicone phase (A) with a viscosity of at least 3 Pas or a consistency of at least 200, and (2) an aqueous phase comprising water, at least one surfactant (B) and optionally at least one water-soluble thickening polymer (C), wherein the relative amounts of water, (B) and optionally (C) are such that the aqueous phase preferably has at least as much viscosity or consistency as the silicone phase (A), said kneading being performed for a sufficient time and with sufficient shear to give an oil-in-water emulsion having a particle size of 0.1-5 .mu.m; and optionally by diluting the medium in water.
