Abstract: The invention relates to a defoamer and/or deaerator based on oil-in-water emulsions which contain(s), in the hydrophobic oil phase, at least one compound that acts as a defoamer and/or deaerator, and optionally contain(s) other constituents. The oil-in-water emulsions contain 0.01 to 3 wt. % of a water-soluble, amphiphilic copolymer which comprises acid groups, or they contain a water-soluble salt thereof as a stabilizer.
