Claim:
1. An organopolysiloxane emulsion composition obtained from emulsion polymerization of an emulsion comprising (A) an organopolysiloxane containing a silanol or organoxy group, (B) 1 to 100 parts by weight of a nonionic surfactant having the general formula (2): wherein R 2 is a straight or branched alkyl group of 1 to 30 carbon atoms or an organic group of R 4 (CO)—, R 4 is a straight or branched alkyl group of 1 to 30 carbon atoms, R 3 is a straight or branched alkyl group of 1 to 30 carbon atoms or an organic group of R 5 (CO)—, R 5 is a straight or branched alkyl group of 1 to 30 carbon atoms, EO is an ethylene oxide group, PO is an alkylene oxide group of at least 3 carbon atoms, a and b each are a number of 0 to 100, a+b>0, and the sequence of EO and PO may be random or in blocks, (C) 1 to 100 parts by weight of a surfactant other than component (B), (D) 0 to 100 parts by weight of a polymerization catalyst, and (E) 1 to 100,000 parts by weight of water; wherein the amounts are based on 100 parts by weight of the component (A).
