Abstract
A silicone-based antifoam composition, in the form of an emulsion, is prepared from the reaction of (A) a primary silicone composition and (B) a polydiorganosiloxane having condensable terminal groups in a nonpolar organic medium selected from the group consisting of polyisobutylene and mineral oil. The reaction of the primary silicone composition (A) and the polydiorganosiloxane (B) produces a secondary silicone composition, which forms the discontinuous phase of the emulsion and the nonpolar organic medium forms the continuous phase of the emulsion. The resulting composition of the invention exhibits antifoam efficacy greater than that of the primary silicone composition.
