Abstract
Thickening can be obtained by adding a silicone latex to the water phase of a water-in-silicone emulsion, instead of adding the silicone latex to the silicone phase of the emulsion. The latex is used in a range of about 0.1-5.0% by weight. Thick emulsions are made by (i) separately preparing a silicone phase containing a silicone polyether and a cyclic siloxane; (ii) separately preparing an aqueous phase containing water and at least one active ingredient; (iii) adding the latex to the aqueous phase; and (iv) combining and mixing the phases.
