Abstract
Defoamer preparations contain a polyorganosiloxane having aryl groups bonded to silicon at a ring carbon, filler particles and/or silicone resin particles, and a polyoxyalkylene polyether containing oxypropylene moieties. In addition to being efficient and compatible, the defoamer compositions retain their efficiency, especially in liquid detergents, after storage.
