  • Patent number: 5236614
    Abstract: Low viscosity and high pH disinfecting and bleaching all purpose cleaning compositions in microemulsion form, suitable in both concentrated and diluted forms for applying to surfaces to be cleaned and disinfected or sanitized, include hypochlorite, higher alcohol sulfate and higher paraffin sulfonate detergents, higher fatty acid soap, alkali metal hydroxide, liquid hydrocarbon, perfume, periodate, branched lower alcohol co-surfactant and water. The compositions are of improved lipophilic soil removing capability when diluted with water, are of about equivalent such capability in neat or concentrated form and are of significantly better hypochlorite stability on aging at room and elevated temperatures, compared to other microemulsion cleaners that contain hypochlorite. Their low viscosities facilitate spraying them from squeeze bottles or pump sprayers onto surfaces to be cleaned and disinfected or sanitized, such as floors and walls.

  • Patent number: 5108643
    Abstract: Stable microemulsion cleaning compositions are described which, in the absence of opacifying component, appear clear to the eye, and which are especialy useful for cleaning surfaces having oily or greasy soils thereon, which comprise synthetic organic detergent, water, co-surfactant of a described type, and perfume (or equivalent hydrocarbon). The detergent composition may be concentrated and may be employed as is, or it may be in dilution with water, in the form of a similarly clear and stable microemulsion. In process aspects of the invention both the concentrated and the diluted compositions may be employed to remove oily and greasy stains from substrates, such as normally shiny bathroom fixture and floor and wall surfaces, including tiles, by a "spray and wipe" process, which leaves the surface shiny, with minimal or no rinsing needed. When the invented compositions are acidic they are also useful for removing lime scale and soap scum from hard surfaces.

  • Patent number: 5082584
    Abstract: An improvement is described in microemulsion compositions containing an anionic detergent, one of the specified cosurfactants, 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 10% of an anionic detergent, 2% to 10% of cosurfactant, 0.4% to 10% of perfume and the balance water or a concentrated microemulsion composition containing, by weight 18% to 65% of anionic and nonionic detergent, 2% to 30% of cosurfactant, 10% to 50% of perfume and the balance water which upon dilution with water will yield said dilute o/w microemulsion composition.

  • Patent number: 5076954
    Abstract: A stable microemulsion cleaning composition is described, which, in the absence of opacifying component, appears clear to the eye, and which is especially useful for cleaning surfaces having oily or greasy soils thereon, which comprises synthetic organic detergent, water, co-surfactant of the described type, and perfume, which is the only "solvent". The concentrated detergent composition may be employed as is, or may be easily diluted with water to form a similarly clear and stable microemulsion. In process aspects of the invention both the concentrated and the diluted compositions may be employed to remove oily and greasy stains from substrates, such as normally shiny bathroom fixture and floor and wall surfaces, including tiles, by a "spray and wipe" process, which leaves the surface shiny. When the invented compositions are acidic they are useful for removing lime scale and soap scum from hard surfaces.Also described are processed for manufacturing and diluting the invented compositions.
