  • Liquid thickener for surfactant systems
    Patent number: 8623132
    Abstract: The present invention generally relates to blends that contain alkoxylated, lipophilic polyol compounds having about three moles of lipophilic, substituents per mole of polyol which are polyethylene glycol methyl glucose trioleate and polyethylene glycol methyl glucose dioleate and, more specifically, to the use of such compounds as thickeners in liquid surfactant compositions.
    Type: Grant

  • Device for the removal and concentration of organic compounds from the atmosphere
    Patent number: 5395426
    Abstract: A device and method for removing, concentrating and analyzing airborne organic compounds. The device includes a nonporous membrane which contains a collection media. The liquid collection media typically includes a component which has a molecular weight that is too large to pass through transport corridors in the nonporous membrane and a component which has a molecular weight which is sufficiently small enough to pass through the transport corridors in the nonporous membrane and thereby forming a thin film on the exterior surface of the device. The collection media can consist of only components too large to pass through the membrane transport corridors. Organic contaminants are trapped in the thin film on the exterior surface of the device or the membrane and transported by concentration gradient diffusion forces into the bulk of the collection media within the nonporous membrane.

  • Binary concentration and recovery process
    Patent number: 5098573
    Abstract: A binary process for the concentration and recovery of contaminants from an aqueous environment by submerging lipids (11) inside of a thin non-porous polymeric film enclosure (10) in an aqueous environment (13) to concentrate the contaminants in the lipids (11) and polymeric film (10); and, recovering contaminants or impurities from the first part or from other contaiminated lipids or biogenic extracts by sumberging the polymeric film enclosed materials (10) in a solvent medium (16).
