  • Patent number: 8192552
    Abstract: The invention relates to a detergent composition, suitable for use in dish washing or laundry, comprising at least 15% of a detersive surfactant(s), and a block copolymer, selected from the group consisting of (block A)-(block B) diblock copolymers, (block A)-(block B)-(block A) triblock copolymers, and (block B)-(block A)-(block B) triblock copolymers, wherein block A and block B derive from alpha ethylenically unsaturated monomers, at least one block being water-soluble. The detergent compositions provide an increased cleaning, and/or a decreased redeposition of the fatty substances once they are removed from a substrate.

  • Patent number: 7064232
    Abstract: The invention relates to the preparation of hydrophobic modified diquaternary cationic monomers and their copolymer as well as the use such monomers and copolymers as thickening agents/rheology modifiers for acidic compositions. The hydrophobic modified diquaternary cationic monomer having the general formula: wherein X is selected from O, NH, or NR; Y is any alkyl, alkylene with or without heteroatoms, and R0, R1, R2 R3, R4, which are identical or different, are selected from C1–C4 alkyl groups, R is selected from any alkyl group with or without heteroatoms, and R5 is a hydrphobe having an alkyl chain of more than 4 atoms.

  • Publication number: 20040194800
    Abstract: An aqueous hard surface cleaner composition contains a surfactant selected from the group consisting of nonionic surfactants, cationic surfactants, amphoteric surfactants, zwitterionic surfactants and mixtures thereof, a germicidal agent, which may be absent if the surfactant comprises a quaternary ammonium surfactant, a hydrophilic polymer comprising styrene sulfonate repeating units, and water, wherein the composition exhibits a pH of greater than or equal to about 6, and provides an easier cleaning benefit.
