A liquid detergent composition comprising an antifoam agent consisting of (I) a reaction product, (II) a nonaqueous liquid continuous phase, and (III) a moderatedly hydrophobic particulate aid. Component (I) is prepared by heating a mixture of (i) a polyorganosiloxane fluid, (ii) a silicon compound, (iii) a finely divided filler and (iv) a catalytic amount of a compound for promoting the reaction of component (i) to (iii) at a temperature of 50 °C to 300 °C. The antifoam agent of the present invention can additionally contain (IV) at least one nonionic silicone surfactant, and (V) a nonreinforcing inorganic filler.
Une composition détergente liquide comprend un agent antimousse constitué de (I) un produit de réaction, (II) une phase continue de liquide non aqueux, et (III) un auxiliaire stabilisant particulaire modérément hydrophobe. On prépare le composant (I) en chauffant un mélange (i) d'un fluide de polyorganosiloxane, (ii) d'un composé de silicium, (iii) d'une charge finement divisée et (iv) d'une quantité catalytique d'un composé favorisant la réaction des composants (i) à (iii) à une température comprise en 50 DEG C et 300 DEG C. L'agent antimousse de la présente invention peut de plus contenir (IV) au moins un tensioactif au silicone non ionique et (V) une charge inorganique non renforçante.
