WETTING AND ANTI-FOAMING AGENTS Abstract of the Disclosure Wetting and anti-foaming agents based on anionic surfactants are provided, which contain (1) 2 to 50 percent by weight of an anionic surfactant, 6 to 50 percent by weight of component (2) and optionally (3), said component (2) being a reaction product, which is insoluble or sparingly soluble in water, with a molecular weight of app. 2000 to 7000, of (a1) monohydric to hexahydric alcohols containing 1 to 6 carbon atoms, monoalkyl- or monoalkylolmonoamines or polyalkylenepolyamines, and (a2) 1,2-propylene oxide, and component (3) being a water-insoluble aliphatic monoalcohol of at least 8 carbon atoms, a reaction product of alkylene oxides and a water-insoluble aliphatic monoalcohol containing at least 8 carbon atoms, a reaction product of alkylene oxides and an alkylphenol, a reaction product of a saturated dicarboxylic acid containing 3 to 10 carbon atoms and 1,2- propylene oxide or polypropylene glycols, a reaction pro- duct of a fatty acid containing 10 to 18 carbon atoms and 1,2-propylene oxide or polypropylene glycols, a reaction product of a fatty acid containing 10 to 18 carbon atoms, a trihydric to hexahydric alcohol and 1,2-propylene oxide, or a reaction product of a fatty acid containing 10 to 18 carbon atoms, a polyalkylenepolyamine and 1,2-propylene oxide, (4) 0 to 30 percent by weight of silicone oil and (5) 2 to 92 percent by weight of water. These new agents are useful for preventing foam formation or for removing foam that has formed for example in processes for finishing and dyeing textile materials or for purifying and processing effluents.
