  • Patent number: 9347027
    Abstract: Described are dishwashing detergents, comprising a builder, a surfactant, and a polymer comprising units derived from an ethylenically unsaturated aminocarboxylate monomer having Formula (I): wherein m is 1, 2, or 3, n is, independently at each occurrence, 1, 2, or 3, R1 is H or C1-C4 alkyl, R2 is H2 or ?O, X is, independently, H, K+, Na+, or NH4+, and an ethylenically unsaturated monomer selected from (meth)acrylic acid.
    Type: Grant

  • Publication number: 20060234890
    Abstract: Floor finishes can be stripped using a substantially nonchlorinated concentrate comprising a floor finish dissolver and an at least partially water-unactivated water thickener. The concentrate is diluted with water at an intended use location to activate the water thickener and noticeably increase within sixty minutes or less the viscosity of the resulting mixture, then applied to a hardened floor finish atop a floor and allowed to soften or dissolve the floor finish so that the finish may be removed from the floor.

  • Publication number: 20060199756
    Abstract: There is provided a laundry composition comprising i) at least one laundry component selected from the group consisting of surfactants, softening agents, and mixtures thereof and ii) at least one ampholytic polymer comprising, as polymerized units, a) 20% to 90% by weight, based on the solid weight of said ampholytic polymer, at least one cationic monomer, b) 10% to 70% by weight, based on the solid weight of said ampholytic polymer, at least one anionic monomer, and c) 0% to 90% by weight, based on the solid weight of said ampholytic polymer, at least one nonionic monomer; wherein the equivalent ratio of said monomer a) to said monomer b) is from 0.33:1 to 1.2:1; and wherein said ampholytic polymer has weight-average molecular weight of 50,000 or less. Further provided is a method of laundering textiles comprising treating said textiles with such laundry compositions.

  • Patent number: 6395185
    Abstract: The invention relates to the inhibition of tripolyphosphate and pyrophosphate scales in aqueous systems involving adding to said aqueous system at least one copolymer comprising the following monomers in polymerized form: (I) 50-80% by weight of one or more weak acids; (II) 2-50% by weight of one or more strong acids; (III) 0-30% by weight of one or more monoethylenically unsaturated C4-C8 dicarboxylic acids; and (IV) 0-30% by weight of one or more monomethylenically unsaturated monomers polymerizable with (I), (II) and (III); wherein the total of monomers (I), (II), (III), and (IV) equals 100% by weight of copolymer. The invention is particularly suited to the inhibition of tripolyphosphate and pyrophosphate scales which occur as a result of using low phosphate (STPP) containing detergent formulations.
