Abstract: A release agent for plastic contains the following components (A) to (E) and has an average particle size of 200 nm or less: (A) 100 parts by mass of an organopolysiloxane having a viscosity at 25° C. of 100 to 100,000 mm2/s; (B) 0.1 to 15.0 parts by mass of one or more anionic surfactants; (C) 1.0 to 30.0 parts by mass of a polyoxyethylene alkyl ether; (D) 0.5 to 15.0 parts by mass of a polyoxyethylene sorbitan fatty acid ester; and (E) 50 to 100,000 parts by mass of water. The release agent is an organopolysiloxane emulsion having excellent dilution stability and mechanical stability and favorable wettability, and hardly cracking plastic.

Abstract: By incorporating a polyoxyalkylene-modified organo(poly)siloxane compound having a specific structure as an emulsifier or emulsification aid, an organopolysiloxane having a high degree of polymerization can be easily emulsified. The obtained organpolysiloxane emulsion composition has excellent resistance to polar solvents including DMF and is dispersible in water. When incorporated into a resin composition of either the solvent-based type including an organic solvent or the water-based type, the emulsion composition can hence impart slipperiness, wear resistance, and glossiness without causing cissing or blushing.

Abstract: An oil-in-water emulsion composition which contains components (A), (B) and (C). (A) 30-70% by mass of a silicone resin composition which is a mixture that is obtained by mixing component (A-1) and component (A-2) at a specific mass ratio, and which has a viscosity of from 100 mm2/s to 4,000 mm2/s at 25° C. (A-1) a silicone resin which has an (R3SiO0.5) unit and an (SiO2) unit at a specific molar ratio (A-2) a volatile oil (B) 2-10% by mass of a polyoxyethylene sorbitan fatty acid ester which has an average number of moles of added ethylene oxide (EO) of 10 or more and an HLB of 11 or more (C) 20-62% by mass of water.
