  • Patent number: 5536451
    Abstract: Aqueous, liquid hard surface detergent compositions having good filming/streaking characteristics contain short chain amphocarboxylate detergent surfactant; hydrophobic, volatile cleaning solvent; and, optionally, zwitterionic detergent surfactant and/or monoethanolamine and/or other specific beta-aminoalkanols for improved filming/streaking and good cleaning. Preferred formulas do not contain large amounts of builders and/or other materials that contribute to bad spotting and filming and said formulas are suitable for general purpose cleaning including cleaning of glass.
    Type: Grant
    Filed: January 18, 1994
    Date of Patent: July 16, 1996
    Assignee: The Procter & Gamble Company
    Inventors: Ronald A. Masters, Michael S. Maile, Martha R. Macy-Ruhe
  • Patent number: 5536450
    Abstract: Aqueous, liquid hard surface detergent compositions having good filming/streaking characteristics contain amido zwitterionic detergent surfactant; linear cosurfactant; hydrophobic perfume; stabilizing additive that is C.sub.2-3 fatty acid and/or C.sub.2-6 alkane diol to help stabilize the hydrophobic perfume, especially as a microemulsion; optionally, cleaning solvent, monoethanolamine and/or other specific beta-aminoalkanols, etc. Preferred formulas do not contain large amounts of builders and/or other materials that contribute to bad spotting and filming and said formulas are suitable for general purpose cleaning including cleaning of glass.
    Type: Grant

  • Patent number: 5534198
    Abstract: Detergent compositions having good filming/streaking characteristics contain effective amounts of specific substantive materials to increase the hydrophilicity of the glass. Preferred formulas contain a amphoteric, including zwitterionic, and optionally, but preferably, anionic detergent surfactant at levels (e.g., from about 0.02 to about 15%); hydrophobic solvent; alkaline material, especially volatile alkaline materials comprising monoethanolamine or certain beta-amino-alkanol compounds; and salt of polycarboxylate, preferably polyacrylate, polymer at effective levels (e.g., from about 0.01% to about 10%, by weight of the composition).
    Type: Grant
    Filed: January 25, 1995
    Date of Patent: July 9, 1996
    Assignee: The Procter & Gamble Company
    Inventors: Ronald A. Masters, Michael S. Maile
  • Patent number: 5531933
    Abstract: Aqueous, liquid hard surface detergent compositions having improved cleaning and good filming/streaking characteristics contain specific polycarboxylate detergent builders at critical levels. Preferred formulas contain a zwitterionic/anionic detergent surfactant mixture at levels (e.g., from about 0.02 to about 15%); hydrophobic solvent; alkaline material, especially volatile alkaline materials comprising monoethanolamine or certain beta-amino-alkanol compounds; and salt of ethylenediaminetetraacetic acid as the detergent builder in levels (e.g., from about 0.05% to about 0.5%, by weight of the composition).
    Type: Grant

  • Patent number: 5382376
    Abstract: Detergent compositions with excellent spotting/filming characteristics comprising propylene glycol/ethylene glycol block copolymer nonionic detergent surfactant, preferably in a surfactant mixture with a nonionic detergent surfactant having a conventional hydrocarbon hydrophobic group and a mixed propylene glycol/ethylene glycol hydrophilic group; optional hydrophobic cleaning solvent; and optional suds control system preferably comprising fatty acid and anionic sulfonated and/or sulfated detergent surfactant. The compositions are preferably in the form of aqueous liquids and preferably have monoethanolamine and/or beta-aminoalkanol present.
