  • Patent number: 6133217
    Abstract: Methods and compositions relating to solubilization of alkylbenzene sulfonate surfactants in detergent formulations. Addition of one or more ethylene oxide/propylene oxide block copolymers to detergents including alkylbenzene sulfonate surfactants may be used to increase solubility of the alkylbenzene sulfonate surfactants. Increased solubility of the alkyl benzene sulfonate surfactants serves to lower the cloud point of the detergents permitting, for example, the formulation of liquid detergent compositions containing greater concentrations of low 2-phenyl linear alkylbenzene sulfonate surfactants.
    Type: Grant
    Filed: August 28, 1998
    Date of Patent: October 17, 2000
    Assignee: Huntsman Petrochemical Corporation
    Inventors: Ronald G. Lewis, David C. Lewis
  • Patent number: 6083897
    Abstract: Methods and compositions relating to solubilization of alkylbenzene sulfonate surfactants in detergent formulations. Addition of one or more polyethylene glycols to detergents including low 2-phenyl linear alkylbenzene sulfonate surfactants may be used to increase solubility of the low 2-phenyl linear alkylbenzene sulfonate surfactants. Increased solubility of the low 2-phenyl linear alkylbenzene sulfonate surfactants serves to lower the cloud point of the detergents, permitting formulation of liquid detergent compositions containing greater concentrations of low 2-phenyl linear alkylbenzene sulfonate surfactants.

  • Patent number: 5612305
    Abstract: Machine dishwashing detergents are disclosed containing a compatible mixture of a low-foaming nonionic surfactant and a high-foaming nonionic surfactant. Dishes and other utensils are cleaned to a sparkling clean spot-free condition by the machine washing detergent composition of the present invention. The machine dishwashing detergent compositions of the present invention are effective especially in controlling foam encountered upon washing dishes and other utensils encrusted with soils generally encountered on dishes, specifically egg and milk-derived protein soils.

    Inventor: Ronald G. Lewis
  • Patent number: 4305930
    Abstract: The disclosure teaches a synergistic deodorant combination of citronellyl senecioate with 3-trifluoromethyl-4,4'-dichlorocarbanilide or 3,4,4'trichlorocarbanilide. The disclosure also teaches synergistic combinations of the foregoing ingredients with 2,4,4'-trichloro-2'-hydroxy diphenyl ether. The foregoing ingredients show synergistic activity as deodorants in various combinations and concentrations as set out in the disclosure. The structures of the ingredients are shown below.

    Date of Patent: December 15, 1981
    Assignee: Armour-Dial, Inc.
    Inventor: Ronald G. Lewis
  • Patent number: 4256600
    Abstract: A translucent deodorant non-germicidal soap bar incorporates selected citronellyl esters, and a suitable alcohol, especially those selected from polyalkylene glycols and/or liquid polyols, to make a soap composition that has superior lime soap dispersancy without loss of translucency, and, in at least one case, is both deodorant and non-germicidal. The polyols have a molecular weight between about 62 to about 342 and the polyalkylene glycols have a molecular weight between about 200 to about 4,000. An effective amount of citronellyl senecioate is added, preferably about 1% by weight. The preferred concentrations of the polyalkylene glycols and polyols range between about 0.5% to 5% by weight.
