ABSTRACT A polysiloxan-polyoxyalkylene composition of the nominal formula: Image wherein R is an alkyl group having 1 to 3 carbon atoms and R°, R', R'' and R''' are individually monovalent polyoxyalkylene polyethers attached to the silicon atom through a difunctional link; and, the polyoxyalkylene of R' is a poly- (oxypropylene-oxyethylene) ether which ontains 20% to 60% oxyethylene by weight and has an average molecular weight of from about 3,000 to about 5,500; the polyoxyalkylene of R'' is a poly- (oxypropylene-oxyethylene) ether which contains 20% to 60% oxyethylene by weight and has an average molecular weight of from about 800 to about 2,900; and the polyoxyalkylene of R''' is a polyoxypropylene polyether having an average molecular weight from about 130 to about 1200; R° can be R', R'' or R''', a and e are individually 0 or 1; b, c, and d are numbers such that b+c+d=y, x and y are positive numbers such that the sum of x+y ranges from 25 to 400 and x is greater than y; wherein the ratio (b+c):d ranges from 0.8 to 1.9.
