  • Patent number: 5767055
    Abstract: An apparatus for surface cleaning is provided in which a first liquid, which includes an oxidizing agent, and a second liquid, which includes a builder or a chelating agent, are initially maintained separately. The apparatus is constructed to facilitate delivery of these two liquids such that they are combined to form an admixture during delivery to a surface to be treated. Either or both of the first and second liquids include a pH-adjusting agent, which is present in an amount such that when the liquids are so delivered, the resulting admixture is maintained at a pH sufficient for cleaning efficacy and stability of the oxidizing agent. The present invention also provides a composition produced by a process of maintaining the two above-mentioned liquids separately and forming an admixture thereof during delivery to a surface to be treated.

    Abstract: The present invention discloses an alkaline cleaning composition for cleaning heavily soiled surfaces such as food fryers, baking pans, high temperature pasteurizers, beer kettles and similar equipment that normally requires caustic soda based cleaners to clean. The present invention is also useful in cleaning ceramics such as restaurant grade ceramic china plates and platters. The present invention is particularly useful in cleaning brass and aluminum parts and equipment without causing corrosion damage. Further, since the cleaning composition of the present invention is not based on caustic soda, the composition is not considered hazardous. Further, the cleaning composition of the present invention dissolves readily in water, providing a solution that can be used in mechanical sprayers, soak-tanks and clean-in-place equipment. Also the cleaning composition may be effectively used at lower temperatures than caustic cleaning agents.

  • Patent number: 5549842
    Abstract: Thickened aqueous hypochlorite compositions comprises (a) an alkali metal hypochlorite, (b) a tertiary amine oxide with one alkyl group having from 10 to 16 carbon atoms and the two other alkyl groups having from 1 to 3 carbon atoms, (c) an alkali metal salt, (d) a pH stabilizer to bring the pH to a level of 11 or higher, (e) a C.sub.10 -C.sub.16 alkali metal sarcosinate, and (f) C.sub.10 -C.sub.14 straight chain alkyl benzene sulfonate. The molar ratio of (b):(f) is from about 5:1 to about 11:1 and is adjusted so that the viscosity of the composition is between 231 and 402 cps. The compositions are useful for general cleaning purposes, particularly bathrooms and toilet bowls, and also as a laundry additive.

  • Patent number: 5543073
    Abstract: A microemulsion cleaning composition having superior solubilizing power and cleaning performance and low concentration of active ingredients has been developed which comprises an organic anionic surface active agent together with an optional nonionic surfactant, an electrolyte, alkylene glycol monoalkyl ether surfactant and water. The monoalkyl moiety of the alkylene glycol ether surfactant must have at least six carbon atoms.

  • Patent number: 5542983
    Abstract: Disclosed is a method and system for the efficient recycling of components involved in removing water insoluble contaminants from the surface of articles. A physically emulsified terpene-containing composition is applied to the surface of articles to effectively remove water insoluble contaminants. Following application, the physically emulsified composition quickly separates, releasing the contaminants and terpene from the water. The water, terpene and contaminants are separated for reuse in accordance with the present process. The physically emulsified composition includes between about 2 weight percent and about 40 weight percent of a terpene in water.

  • Patent number: 5538664
    Abstract: Hard surface detergent compositions comprise nonionic detergent surfactant; tripropylene glycol or short chain alkyl ether of tripropylene glycol as a hydrophobic cleaning solvent; and optional, but preferred suds control system 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. The compositions clean vinyl no-wax flooring without rinsing and without substantial filming/streaking.
