Defoamer compositions which act rapidly and over an extended period of time employ organopolysiloxanes having alkylene linking groups bridging siloxy groups, a filler, a silicone resin, and phosphoric acid.

Defoaming formulations containing organopolysiloxanes

Rapid and long lasting defoaming is accomplished by use of a defoamer formulation employing an organopolysiloxane having siloxy groups linked by an alkylene group, a filler, a silicone resin, a silanol-terminated organopolysiloxane, and an inorganic or organic acid.

Defoamer formulations with rapid knockdown and extended performance contain specific polyorganosiloxanes having alkylene linkages between siloxy groups, silicone resins, fillers, a polyoxyethylene surfactant, and an organic or inorganic acid.

A composition comprising: from 25 to 80 wt % of at least one vinyl acetate-vinyl alcohol copolymer, where the copolymer comprises at least 85 mol % vinyl alcohol units; from 1 to 25 wt % of at least one polyhydric alcohol; and from 5 to 50 wt % of a first active agent which is: a polymer comprising a monomer having at least one carboxylic acid group or a salt or ester thereof; a polymer comprising a monomer having at least one imine group or a salt thereof; or a polymer comprising a monomer having at least one aspartic acid group or a salt or ester thereof. A package containing the composition. A method of preparing the composition, the method comprising extruding the composition. A method of machine dishwashing, wherein the first active agent is released into wash water over the course of a plurality of dishwashing programs.
