US 2003/0143176 A1 · Compositions containing silicone oil-in-water emulsions, salts, alcohols and solvents

Abstract

Silicone oil-in-water emulsions are prepared using a silicone polyether as the surfactant, and the silicone oil-in-water emulsions are stable in an aqueous media in the presence of salts such as electrolytes, alcohols, solvents, and combinations thereof. The silicone oil-in-water emulsions are prepared by (i) polymerizing silicon atom containing monomers in water containing the monomer, a silicone polyether, a catalyst, and optionally an organic surfactant(s), until a silicone oil of a desired molecular weight is obtained. The silicone oil-in-water emulsions possess utility as additives in various coating products, personal care products, household care products, automotive care products, and petroleum products.

Dependent claims

A method of making a silicone oil-in-water emulsion comprising (i) preparing an aqueous phase containing water, a silicone polyether surfactant, and optionally one or more organic surfactants;

(ii) preparing an oil phase comprising a silicon atom containing monomer polymerizable to a silicone oil of a desired molecular weight;
(iii) combining the aqueous phase and the oil phase;
(iv) adding a polymerization catalyst;
(v) heating and agitating the combined phases for a time sufficient to allow the silicon atom containing monomer to polymerize to a silicone oil having the desired molecular weight;
and (vi) recovering a silicone oil-in-water emulsion containing the silicone oil of the desired molecular weight.
