    Assignee: Lever Brothers Company, Division of Conopco Inc.
    Inventors: Eddie N. Gutierrez, Shang-Ren Wu
  • Patent number: 5466394
    Abstract: Heavy duty liquid detergent compositions containing an anionic surfactant component and a quaternary ammonium fabric-softening agent of the formula ##STR1## The anionic surfactant component comprises, by weight of the composition, from about 5% to 40% of alkyl polyethoxylate sulfates and no more than about 5% of alkyl benzene sulfonates. The compositions are substantially clear and isotropic, provide excellent cleaning of soils and provide softening through the wash and anti-static benefits. The compositions preferably also contain a fatty acid component, ethoxylated nonionic surfactant, a detergent builder and enzymes.

  • Patent number: 5464552
    Abstract: The invention provides a phase stable liquid detergent containing at least one particulate oxidant, comprising:a) a liquid phase which comprises: i) an effective amount of at least one surfactant selected from the group consisting of anionic, nonionic, cationic, amphoteric, zwitterionic surfactants, and mixtures thereof; ii) a liquid carrier therefore, comprising organic Solvents, water, or a mixture thereof;b) an effective amount of a particulate oxidant stably suspended in said liquid phase, which maintains oxidative stability, said oxidant being selected from the group consisting of alkali metal perborate and percarbonates; andc) an oxidant stabilizer selected from the group consisting of alkali metal chloride, alkali metal borate, boric acid and mixtures thereof.

    Inventors: David Peterson, Gregory V. Buskirk
  • Patent number: 5462690
    Abstract: An improvement is described in microemulsion compositions which contain an anionic detergent, a nonionic surfactant, a grease release agent, a hydrocarbon ingredient, and water which comprises the use of a water-insoluble odoriferous perfume as the essential hydrocarbon ingredient in a proportion sufficient to form either a dilute o/w microemulsion composition containing, by weight, 1% to 20% of an anionic detergent, 6 to 50% of a cosurfactant, 0.1% to 10% of a grease release agent, 0.4% to 10% of perfume and the balance being water as well as all purpose hard surface cleaning composition or light duty liquid detergent compositions which contain a grease release agent.

    Assignee: Colgate-Palmolive Co.
    Inventor: Robert Rhinesmith
  • Patent number: 5454984
    Abstract: A synergistic cleaning composition has been discovered comprising an aqueous solution a quaternary ammonium compound component; a nonionic surfactant component; and a glycol ether solvent. Surprisingly, the combination of the quaternary ammonium compound component, the nonionic surfactant component, and glycol ether solvent provides a synergistic effect where the cleaning composition functions with a low level of quaternary ammonium compound component while still maintaining at least one of the following desirable properties, as follows: an acceptable cleaning efficacy; a low level irritation or toxicity profile; and/or a broad spectrum antimicrobial activity.
