ABSTRACT:
The self-emulsifiable silicone composition of the invention comprises (a) an organopolysiloxane having polyoxyalkylene moieties and perfluoroalkyl-containing organic groups and represented by the average unit formula ##STR1## in which R is hydrogen atom or a monovalent hydrocarbon group having from 1 to 6 carbon atoms, G is polyoxyalkylene residue represented by the general formula ##STR2## and (b) an organopolysiloxane having perfluoroalkyl-containing organic groups represented by the average unit formula ##STR3## The composition is useful as an antifoam agent and, despite the high self-emulsifiability and stability, exhibits excellent defoaming activity even at relatively low temperatures around room temperature in contrast to conventional silicone-based antifoam compositions.
