  • Patent number: 5719244
    Abstract: Latex binders are disclosed which are used to prepare freeze-thaw-stable latex coating compositions which may be free of volatile freeze-thaw/open-time additives. The latex binders are prepared by combining a polymer which is the polymerization product of a polymerizable saccharide monomer, an acrylic monomer and, optionally, a monomer selected from styrenic monomers, ionic monomer and wet adhesion monomers. The latex coating compositions are freeze-thaw stable, even in the total absence of a volatile freeze-thaw additive, and exhibit improved open-time when compared to a latex coating composition which does not contain a volatile freeze-thaw additive. Methods for preparing the freeze-thaw-stable latex coating compositions are also disclosed.

  • Patent number: 5385685
    Abstract: The present invention relates to detergent compositions comprising a glyceroglycolipid having one or two ether linkages for use as a surfactant or cosurfactant in the detergent compositions.
    Type: Grant
    Filed: November 25, 1992
    Date of Patent: January 31, 1995
    Assignee: Lever Brothers Company, Division of Conopco, Inc.
    Inventors: Robert W. Humphreys, Anthony Hung, Shang-Ren Wu, Abid N. Khan-Lodhi
  • Patent number: 5358656
    Abstract: The present invention relates to liquid detergent compositions wherein the detergent active mixture of the compositions comprises 65 to 99% of a glyceroglycolipid compound having an amine linkage and 1 to 35% of a nonionic surfactant. Unexpectedly, applicants have discovered a synergy in the mixture of these surfactants which leads to enhanced detergency.
