  • Patent number: 9832990
    Abstract: A composition and a method of preparing the composition are provided herein. The composition comprises an active substance and a polymeric additive comprising at least one unit represented by the formula (I): wherein each R is independently selected from the group of a hydrogen atom, an alkyl group, an aryl group, and combinations thereof; and Z comprises at least 10 units represented by the formula (II): wherein each R1 is independently selected from the group of a hydrogen atom, an alkyl group, an aryl group, a carbonyl group, a hydroxyl group, an ether group, and combinations thereof and R2 is a C1-C10 hydrocarbon group. The polymeric additive further comprising at least one unit represented by the formula (III): A??(III) wherein A is an alkyleneoxy group having from 2 to 10 carbon atoms.

  • Patent number: 8653016
    Abstract: The present invention provides a biodegradable cleaning composition that includes a surfactant component including an ethoxylated 2-propyl heptanol, a chelating component including a tri-sodium salt of methylglycinediacetic acid and an emulsifier component including an ethoxylated hexanol having the formula C6H13O(CH2CH2O)H. The ethoxylated 2-propyl heptanol has the formula C5H11CH(C3H7)CH2O(C2H4O)pH, wherein p is a number of from 3 to 6. The composition also includes water and an acid component to establish a pH of the composition at less than 2. The composition is substantially free of solvents thereby reducing emission of volatile organic compounds and reducing potential environmental pollution and health hazards. The composition is also effective in removing rust, lime soap, and metal salts of fatty acids from hard surfaces including metal, vinyl, and fiberglass.

  • Patent number: 5733856
    Abstract: A laundry detergency boosting polymer blend additive is made up of:a) a graft copolymer of polyalkylene oxide with vinyl ester, the graft copolymer having a molecular weight within the range of about 5,000 to 50,000; andb) at least one polycarboxylate selected from the group consisting of acrylic/maleic acid copolymers having a molecular weight within the range of about 1,000 to 100,000, and polyacrylic acid having a molecular weight of from about 1,000 to 100,000. The polymer blend additive is effective in water with an ion hardness in the range of about 50 to 500 ppm. The detergency boosting performance of the polymer blend additive is maintained or increased as the concentration of the hardness ions in water is increased.
