Abstract:
Efficient defoamer and foam prevention formulations contain an organopolysiloxane defoamer and an efficiency promoting waxy β-ketocarbonyl-functional organosilicon compound. The compositions also preferably contain a filler and a silicone resin, and are highly efficient in surfactant-containing aqueous systems such as detergents and cleaners.
