Case 1-12099/+ Foam inhibitors and use thereof for defoaming aqueous systems Abstract Foam inhibitors for aqueous systems which contain a fatty acid salt of a polyvalent metal, especially an alkaline earth metal or aluminium, an anionic surfactant or a non-ionic reaction product of an alcohol or an alkyl phenol with an alkylene oxide, an aliphatic alcohol containing 5 to 18 carbon atoms or a mixture of such alcohols, and a hydrophobic organic solvent or solvent mixture. The novel foam inhibitors are stable, they are miscible to any extent with water or organic solvents and can be used e.g. for defoaming aqueous dyebaths, treatment baths, printing pastes, pulp suspensions, paints, detergent solutions or also wastewaters.
