  • Method of removing volatile compounds from emulsions
    Patent number: 10537853
    Abstract: Various embodiments disclosed relate to methods of separating volatile compounds from a liquid feed mixture comprising an emulsion. In various embodiments, the method includes contacting a first side of a first membrane with a liquid feed mixture including an emulsion having a polymer, and at least one volatile compound. The method can also include contacting a second side of the first membrane with a sweep medium including at least one a sweep fluid to produce a permeate mixture on the second side of the first membrane and a retentate mixture on the first side of the first membrane, wherein the permeate mixture is enriched in the volatile compound, and the retentate mixture is depleted in the volatile compound.
    Type: Grant

  • Process For Making Polysiloxane Emulsions
    Publication number: 20130116381
    Abstract: A process is described for making polysiloxane emulsions by emulsion polymerizing a silicon monomer or oligomer under an elevated pressure. The process produces emulsions of a polysiloxane containing a lower amount of octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5) than conventional emulsion polymerization techniques. The emulsions by the inventive method can be used in cosmetic and personal care products, for textile treatment, lubrication, release, and building material protections.
