Abstract
Defoamer compositions which exhibit both high defoaming activity as well as good storage stability are prepared by mixing at least an organopolysiloxane having a defined but limited fraction of silicon-bonded hydroxyl and/or alkoxy groups and hydrophilic silica, followed by heating until the viscosity of the mixture has fallen to less than 50% of its value prior to heating.
