  • Patent number: 6599970
    Abstract: Aqueous compositions having enhanced thickening properties containing lipophilically-modified copolymer thickeners and one or more hydrophilic surfactants are disclosed. In particular, aqueous compositions containing (i) lipophilically-modified copolymers containing at least 5% of selected lipophilically-modified components and (ii) surfactants having an HLB value of greater than 15 are useful for the thickening of a range of personal, domestic and industrial products.

  • Patent number: 6348509
    Abstract: The invention provides a method of inhibiting the formation of stable water in oil emulsions which are typically formed during the production of crude oil. The method involves the addition of one or more amphiphilic compounds which may comprise a hydrophilic backbone and hydrophobic groups attached thereto. The hydrophilic backbone may comprise polymerised units of one or more monomer compounds which may be selected from one or more of alkylene oxide, (meth)acrylic acid, acrylate, urethane, cellulose and vinyl alcohol. The hydrophobic groups may be attached to the hydrophilic backbone in one or more of the following positions: at one or more of the ends of the backbone, either regularly or randomly spaced along the length of the backbone, and as linking groups to link two or more portions of the hydrophilic backbone together.

  • Patent number: 5922661
    Abstract: A detergent tablet is disclosed which comprises at least 50 wt. % of a non-phosphate builder and from 0 to 20 wt. % of a phosphate builder, and has incorporated therein as binder from 0.3 to 5 wt. % of a neutralised polymer of hydrophilic or hydrophobic monomers which have a glass transition temperature (Tg) of from 40 to 120.degree. C., which monomers comprise(meth)acrylic acid, maleic anhydride, alkyl (meth)acrylates, alkylhydroxy (meth)acrylates, or styrene, the polymer having a weight average molecular weight of from 10,000 to 120,000.

  • Patent number: 5916967
    Abstract: Aqueous compositions comprising two or more surfactants and an associative thickener, where the type and amounts of the surfactants are selected to provide an aqueous solution having enhanced thickening properties, is disclosed. In particular, selected surfactant mixtures combined with certain hydrophobically-modified polyetherurethane thickeners provide enhanced thickening properties that are not available when the individual surfactants are combined with thickener. A method for improving the thickening properties of aqueous solutions using the mixed surfactant/associative thickener is also disclosed. The mixed surfactant/associative thickeners of the invention are useful as thickening agents in a variety of formulations such as paints, coatings, cosmetics, personal care items and cleaners.
