TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The encapsulating material comprises a surfactant of hydrophilic lipophilic balance (HLB) below 8 which is crystalline and has a melting point of 40-100 degrees C. The surfactant of HLB 8 is a fatty acid or fatty acid ester. The organic encapsulating material is associated with a hydrophobic silicaceous material including a branched silicone resin containing monovalent trihydrocarbonsiloxy (M) groups of formula R3SiO1/2 and tetrafunctional (Q) groups SiO2 or trivalent hydrocarbonsilsesquioxy (T) RSiO3/2 groups. The hydrophobic silicaceous material is a silica with surface area greater than 100 m2/g that is rendered hydrophobic. The silicone active material is an antifoam comprising a polyorganosiloxane fluid and a hydrophobic filler. The polar organic liquid continuous phase comprises a polyether including a polyoxyethylene polyoxypropylene block copolymer. The three phase contact angle between the solid organic encapsulating material, the silicone antifoam, and the continuous phase is 45-110 degrees when measured through silicone at 25 degrees C after 10 minutes of equilibrium. The polar organic liquid has dispersed in it a polyorganosiloxane fluid, a surfactant of HLB below 8, and a hydrophobic silicaceous material. The polyorganosiloxane fluid is linear, branched, or crosslinked polydiorganosiloxane having a silanol level of 0.01-0.05 wt.%.R = monovalent hydrocarbon group.Preferred Composition: The organic encapsulating material is a blend of 50-100 wt.% crystalline surfactant of HLB 8 and 0-50 wt.% alkylmethyl polysiloxane wax or oil or fat which is not miscible with the polar organic liquid. EXAMPLE - A foam control composition was prepared by mixing 4.4 parts antifoam premix made by blending 95 parts of 1000 cSt trimethyl terminated polydimethylsiloxane fluid and 5 parts Sipermat D11 (RTM:silicon-treated silica), with 17.5 parts premix comprising Sipermat D11 (food grade polydimethylsiloxane treated) at 65 degrees C for 15 minutes at 300 rpm. The temperature was raised to 85 degrees C and mixing was continued for another 15 minutes. The rpm was increased to 450 for an additional 30 minutes of mixing. 78.13 parts of Pluronic L121 liquid polyether was added with an additional 30 minutes of mixing at 450 rpm. Finally the concentrate was cooled to ambient temperature with mixing at 600 rpm for 30 minutes. The obtained composition exhibited the encapsulated shell-like structure.
