FIELD: chemistry.SUBSTANCE: invention relates to compositions for controlling foaming for liquid detergent systems. Disclosed is a composition for controlling foaming, which contains: (A) an organosilicon antifoaming agent containing (i) organopolysiloxane having at least one substitute of formula X-Ar linked to silicon, where X is a divalent aliphatic group linked to a silicon atom through a carbon atom, and Ar is an aromatic group, (ii) an organosilicon polymer of formula R?SiO, where Ris a hydrocarbon group, hydrocarbon oxy or hydroxyl, and a has an average value from 0.5 to 2.4, and (iii) hydrophobic filler, and (B) organopolysiloxane resin containing at least one polyoxyalkylene group, as well as tetrafunctional siloxane links of formula SiOand monofunctional siloxane links of formula R?SiO, wherein the total number of tetrafunctional siloxane links in the resin is not less than 50% of the total number of siloxane links, and Ris a hydrocarbon group. Also disclosed is a liquid detergent containing one or more surfactants, weater and said composition for controlling foaming.EFFECT: disclosed composition is safe and inert to detergent components, provides stability of the mixture in detergents and excellently control foaming.4 cl, 1 dwg, 2 tbl, 8 ex |
