Abstract:
1. An oil-in-water organopolysiloxane emulsion composition that characteristically comprises (A) 100 weight parts of organopolysiloxane or organopolysiloxane mixture that is represented by the general formula R (B) 0.5 to 35 weight parts of organosiloxane that has a viscosity at 25° C. of 10 to 100,000 mPa·s and that characteristically contains in the molecule at least one type of organic group selected from the group consisting of nitrogen atom-containing organic groups and epoxy-functional organic groups, (C) 0.5 to 35 weight parts of nonionic surfactant selected from the group consisting of ethylene glycol/aliphatic acid esters, polyethylene glycol/aliphatic acid esters, propylene glycol/aliphatic acid esters, polypropylene glycol/aliphatic acid esters, glycol/aliphatic acid esters, trimethylolpropane/aliphatic acid esters, pentaerythritol/aliphatic acid esters, glucoside derivatives, aliphatic acid esters of glycerol alkyl ethers, trimethylolpropaneoxyethylene alkyl ethers, lanolin and its derivatives, caster oil derivatives, hardened caster oil derivatives, sterols and its derivatives, polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene trimethylolpropane/aliphatic acid esters, polyoxyethylene alkyl ether/aliphatic acid esters, polyoxyethylene-polyoxypropylene glycols, polyoxyethylene-polyoxypropylene alkyl ethers, polyoxyethylene-polyoxypropylene polyhydric alcohol ethers, glycerol/aliphatic acid esters, polyglycerol/aliphatic acid esters, polyoxyethylene glycerol/aliphatic acid esters, sorbitan/aliphatic acid esters, polyoxyethylene sorbitan/aliphatic acid esters, and sucrose/aliphatic acid esters, (D) 0.5 to 15 weight parts of water-soluble solvent, and (E) 10 to 150 weight parts of water, wherein the content of (F) ionic surfactant in the composition is less than 0.1 weight part per 100 weight parts component (A).
