Granulated Foam Control Composition

A granulated foam control composition comprises a foam control agent based on a polydiorganosiloxane fluid, an organic additive of melting point 45''17C to 100° C. comprising a polyol ester, a water-soluble particulate inorganic carrier and a polymer having a net cationic charge. The mean...

Zusammenfassung:A granulated foam control composition comprises a foam control agent based on a polydiorganosiloxane fluid, an organic additive of melting point 45''17C to 100° C. comprising a polyol ester, a water-soluble particulate inorganic carrier and a polymer having a net cationic charge. The mean number of carbon atoms in the organo groups of the polydiorganosiloxane fluid is at least 1.3. The foam control agent includes a hydrophobic filler dispersed in the polydiorganosiloxane fluid, and optionally an organosilicone resin. The polyol ester is miscible with the polydiorganosiloxane fluid.
