  • Automatic dishwashing formulation with dispersant copolymer
    Patent number: 11680230
    Abstract: An automatic dishwashing composition is provided including a builder; a phosphonate; a nonionic surfactant; and a dispersant polymer comprising: 60 to 98 wt % of structural units of formula I wherein each R1 is independently selected from a hydrogen and a —CH3 group; and 2 to 40 wt % of structural units of formula II wherein each R2 is independently selected from a —C1-4 alkyl group and wherein each R3 is independently selected from a hydrogen and a methyl group.
    Type: Grant
    Filed: May 28, 2019
    Date of Patent: June 20, 2023
    Assignees: Dow Global Technologies, Rohm and Haas Company
