  • Aqueous based surfactant compositions
    Patent number: 6177396
    Abstract: The use of a stabiliser comprising a hydrophilic polymeric chain of more than four hydrophilic monomer groups and/or having a mass greater than 300 amu, linked at one end to a hydrocarbon-soluble hydrophobic group to reduce or prevent the flocculation of systems comprising a flocculable surfactant and a liquid medium which is capable of flocculating the surfactant and in which the stabiliser is capable of existing as a micellar solution at a concentration of at least 1% by weight.
    Type: Grant
    Filed: July 17, 1996
    Date of Patent: January 23, 2001
    Assignee: Albright & Wilson UK Limited
    Inventors: Richard Malcolm Clapperton, John Reginald Goulding, Boyd William Grover, Ian Foster Guthrie, William Paul Haslop, Edward Tunstall Messenger, Jill Elizabeth Newton, Stewart Alexander Warburton
  • Method of preparing a drilling fluid comprising structured surfactants
    Patent number: 6166095
    Abstract: A pourable aqueous composition for use as, or for dilution to form, a drilling mud comprises a least 2% by weight of a water soluble polyvalent metal salt of an alkyl polyoxyalkylene sulphuric or carboxylic acid, and at least 1% by weight of a corresponding salt of an alkyl benzene sulphuric acid, preferably in the presence of a water soluble inorganic salt or base of said polyvalent metal.
    Type: Grant
    Filed: October 15, 1996
    Date of Patent: December 26, 2000
    Assignee: Albright & Wilson UK Limited
    Inventors: Edward Bryan, Boyd William Grover, William John Nicholson

  • Functional fluids and liquid cleaning compositions and suspending media
    Patent number: 5964692
    Abstract: Aqueous structured surfactants, e.g., lamellar, or preferably spherulitic systems optionally containing suspended solids are used as functional fluids, such as drilling fluids, cutting fluids, hydraulic fluids, heat transfer fluids, construction muds and lubricants. A composition consisting essentially of: water; a surfactant or mixture of surfactants present in a concentration sufficient to form a mobile spherulitic or dispersed lamellar phase in the absence of an electrolyte; and a substantially water insoluble functional material, suspended in the composition, the composition being substantially free from electrolyte.
    Type: Grant
    Filed: June 6, 1995
    Date of Patent: October 12, 1999
    Assignee: Albright & Wilson Limited
