    摘要: A foam control agent which is free from hydrocarbon oils and comprises (A) an organopolysiloxane with 0 to 60% of units (i) ##EQU1## wherein R denotes a C.sub.8 hydrocarbon group and a is 0-3, and 40 to 100% of units (ii) ##EQU2## wherein R" is --Z.sub.z --R' with R' being an C.sub.9-35 alkyl, Z is a linking group and z is 0 or 1, b 0, 1 or 2, c 1 or 2 and b+c 1, 2 or 3, provided more than 70% by weight of the carbon content of (A) is due to R", (B) a finely divided hydrophobic particulate material and (C) optionally a MQ organosilicon resin. The agents give improved performance and stability e.g. in detergent powders.
