Defoamer compositions containing a plurality of defined organopolysiloxanes exhibit very short initial foam collapse and yet exhibit long lasting defoaming activity when added to aqueous media prone to foaming.

A recycled cellulose pulp composition is provided which comprises recycled cellulosic fibers and cellulose ester staple fibers. The recycled cellulose pulp containing co-refined re-cycled cellulose fibers and cellulose ester staple fibers can be added to a hydropulper and fed back through a refiner to make wet laid products.

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.

Defoamer compositions containing a plurality of defined organopolysiloxanes exhibit very short initial foam collapse and yet exhibit long lasting defoaming activity when added to aqueous media prone to foaming.

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.

Disclosed herein are methods of defoaming industrial process streams, the methods comprising adding to the industrial process stream an emulsion stabilized by Janus particles, wherein the Janus particles comprise at least one hydrophobic surface and at least one hydrophilic surface, and wherein the emulsion comprises silicone emulsion droplets in a continuous aqueous phase. Also disclosed herein are defoamer compositions comprising Janus particles and methods of making such compositions.
