  • Patent number: 6090768
    Abstract: Liquid laundry detergent compositions provide good detergency for the cleaning of garments and textiles, as well as further providing a germicidal action to textile fabrics in a domestic laundering process. There is provided an aqueous, germicidal liquid detergent composition comprising:A) a major anionic surfactant constituent selected from alkylethercarboxylates and alkylethersulfonates;B) a cationic germicidal surfactant;C) a nonionic surfactant preferably selected from alcoholalkoxylates, akylphenol alkoxylates, alkylpolyglycosides, amine oxides and alkanolomides, wherein the value of the cationic surfactant to the major anionic surfactant is 1:2 or greater; and,D) a compatible optical brightener constituent.Further conventional additives may be included as optional constituents.

  • Patent number: 5939374
    Abstract: A blooming type, hard surface cleaning concentrate composition includes as a blooming system the following essential constituents: a cationic quaternary ammonium surfactant; an anionic carboxylated alcohol alkoxylate surfactant; a surfactant compatibilizing agent; and, water. Further optional constituents may also be included including additional anionic, cationic, nonionic, amphoteric and zwitterionic surfactants especially to provide a further detersive effect; organic solvents such as alcohols, ethers, glycol ethers to aid in stain solubilization, as well as conventional additves such as coloring agents including dyes, fragrances, and others. In preferred embodiment, the concentrate compositions and cleaning compositions also provide a germicidal effect to hard surfaces. The cleaning concentrates exhibit a charateristic bloom when admixed to a larger volume of water, yet are substantially clear and shelf stable as concentrate compositions.
