  • Particulate foam control agents and their use
    Patent number: 5861368
    Abstract: A method of providing a foam control agent with 1 to 30 parts of a silicone antifoam and 70 to 99 parts of a zeolite carrier, with the ability to release some of the antifoam within 10 minutes of being dispersed in an aqueous surfactant solution, by deposition 5 to 70% of the antifoam of an organo-polysiloxane polyoxyalkylene copolymer, onto the zeolite carrier not later than depositing the silicone antifoam. Also claimed is the use of the copolymer to achieve that end and compositions where the antifoam is branched or high viscosity. Also claimed is encapsulated agents.
    Type: Grant
    Filed: January 18, 1997
    Date of Patent: January 19, 1999
    Assignee: Dow Corning S. A.

  • Particulate foam control agents
    Patent number: 5589449
    Abstract: A particulate foam control agent comprises 1 to 30 parts silicone antifoam, 70 to 99 parts zeolite carrier, 1 to 60% of the antifoam of an organopolysiloxane polyoxyalkylene copolymer, deposited onto the zeolite carrier not later than the antifoam and 1 to 40 parts by weight of a polycarboxylate-type binder or encapsulant. This combination give good release in early stages, storage stability and powder characteristics.
