ABSTRACT:
Disclosed is a silicone-based antifoam composition capable of exhibiting high defoaming activity even at a high temperature with excellent durability so as to be useful in dyeing processes. The composition comprises, as the principal ingredient, a polyoxyalkylene-modified polydimethylsiloxane, of which, different from conventional polyoxyalkylene-modified polydimethylsiloxanes, the polyoxyalkylene groups consist of two different types relative to the molar proportion of the oxyethylene units and oxypropylene units, in addition to a silicone oil compound of a silica filler, a poly(oxyethylene-oxypropylene) copolymer and low-molecular polydimethylsiloxane terminated at each molecular chain end with a dimethyl hydroxy silyl group.
