  • Patent number: 5547918
    Abstract: A biocidal or agrochemical composition comprising particles or droplets of a substantially water-insoluble or sparingly-soluble biocidally-or agrochemically-active substance cosuspended, by an aqueous structured surfactant, with an aliphatic hydrocarbon or glyceride oil, wherein the weight ratio of said surfactant to said active substance is less than 20:1
    Type: Grant
    Filed: June 1, 1995
    Date of Patent: August 20, 1996
    Inventors: Jill E. Newton, Richard M. Clapperton, William J. Nicholson

  • Patent number: 4871467
    Abstract: Pourable, fluid, non sedimenting, laundry detergent composition, comprising water, surfactant, builder, a surfactant desolubilizing electrolyte and, optionally, the usual minor ingredients, consist essentially of: at least one predominantly aqueous liguid phase which is separable into a distinct layer by centrifuging the composition at 800 times normal earth gravity at 25.degree. C. for 17 hours, and which contains at least part of the electrolyte and less than 75% by weight, preferalby less than 10% by weight, of the surfactant, and one or more other phases which together contain at least part of the builder as solid particles dispersed in the composition and at least part of the surfactant, preferably either as a network of solid surfactant hydrate, or as a "G" phase liquid crystal which may be associated with an "L" phase, micellar solution.
    Type: Grant
