A foam control agent comprising 100 parts by weight of a water-insoluble organic liquid, from 0.1 to 20 parts by weight of a first hydrophobic filler with a size of no more than 20µm, preferably silica, and from 0.1 to 20 parts by weight of a second hydrophobic filler having a size of at least 30µm, preferably an organopolysiloxane resin, said fillers being insoluble in the organic liquid. The foam control agent is particularly useful as an antifoam in detergent compositions, paper pulp manufacture, textile dyeing or cutting oils. |
