  • Patent number: 6583101
    Abstract: Hard floor finishes and other stubborn soils can be removed using an aqueous dispersion of an alkylene glycol phenyl ether solvent combined with an ether alcohol solvent/coupler. Each component is used at a concentration that result in the creation of a visible dispersed appearance of the aqueous dilute use solutions. We have found that the alkylene glycol phenyl ether, in combination with at least one ether alcohol coupler or solvent, interacts with the aqueous medium to surprisingly provide enhanced cleaning performances. Hard to remove soils such as highly crosslinked urethanes and acrylic materials can be solubilized and removed by the alcohol solvent dispersions of the invention. We have found that the alkylene phenyl ether solvent requires a specific coupler cosolvent for activity. Such activity can be enhanced by the presence of a second coupler cosolvent and the use of a specific class of nonionic surfactant materials.

  • Patent number: 5895782
    Abstract: A solution for cleaning metal surfaces particularly non ferrous alloys such as copper, brass and high strength aluminum alloys. The solution is prepared by mixing Ca(OH).sub.2 and KOH with equivalent sulfuric acid in water then passing the solution through a 10 micron filter. the resulting concentrate can be used full strength or diluted depending on the degree of surface oxidation of the metal to be treated.

  • Patent number: 5877134
    Abstract: Automatic dishwashing detergent compositions comprising a mixed nonionic surfactant system comprising low cloud point and high cloud point nonionic surfactants. The low cloud point nonionic surfactant has the formula:R.sub.1 O?CH.sub.2 CH(CH.sub.3)O!.sub.x ?CH.sub.2 CH.sub.2 O!.sub.y CH.sub.2 CH(OH)R.sub.2wherein R.sub.1 is a linear or branched, aliphatic hydrocarbon radical having from about 4 to about 18 carbon atoms; R.sub.2 is a linear or branched aliphatic hydrocarbon radical having from about 2 to about 26 carbon atoms; x is an integer having an average value of from 0.5 to about 1.5; and y is an integer having a value of least about 15. The high cloud point nonionic surfactant comprises an ethoxylated surfactant derived from the reaction of a monohydroxy alcohol containing from about 10 to about 16 carbon atoms, with from about 6 to about 15 moles of ethylene oxide per mole of alcohol on an average basis and having a hydrophile-lipophile balance value within the range of from about 12 to about 14.

  • Patent number: 5872089
    Abstract: A descalant means, comprising L.sub.E structured liquid crystals which when placed close to, or into a liquid stream, cause the formation of microscopic liquid crystalline structures, which act as nucleation sites for the formation of crystal structures of normally liquid-soluble or insoluble salts, and other suspended particles, these crystalline structures being chemically stable and causing a large reduction in the scaling potential of the liquid, thereby avoiding scale buildup on metal or other containment surfaces and also initiating descaling of surfaces already containing scale buildup. Furthermore, said means will reduce the amount of detergents, soaps, surfactants and polymers required in washing and other forms of water use.
