Abstract
A dispersion contains: (a) a polyorganosiloxane with at least 90 mole % dimethyl D units and viscosity of one kPa*s or more dispersed as 0.5-20 micrometer particles; (b) a condensation product of: (i) a polysiloxane resin (Mw of 4,000-50,000) with composition: (RSiO)(SiO)(ZO)where a is 0.30-0.60, b is 0.40-0.70, c is 0.05-0.20, a+b is one, R is selected from hydrogen, Calkyl groups and aryl groups, and Z is selected from H, and Calkyls; and (ii) a polyoxyalkylene polymer (Mn of 4,500-50,000) with composition: A—O—(CHO)(CHO)—A' where e/p is 1-9, A and A′ are selected from hydrogen, alkyl, substituted alkyl, aryl, and substituted aryl groups and at least one of A and A′ is H; (c) non-aqueous fluid carrier miscible with (a); and (d) monoterpene; the weight-ratio of (c) to (b) is 0.5-1; weight-ratio of (b) and (c) to (a) is 0.01-0.50; and the composition contains below one ppm aromatic solvent.
