An automatic dishwashing composition is provided including a builder; a nonionic surfactant; and a dispersant polymer comprising: (a) >60 to <90 wt %, based on weight of the dispersant polymer, of structural units of formula I wherein each Ris independently selected from a hydrogen and a —CHgroup; and (b) >10 to <40 wt %, based on weight of the dispersant polymer, of structural units of formula II wherein each Ris independently selected from the group consisting of a Chydroxyalkyl group and a Calkoxy group; and wherein each Ris independently selected from a hydrogen and a methyl group.

Dishwashing formulation with dispersant copolymer

An automatic dishwashing composition is provided including a builder; a phosphonate; a nonionic surfactant; and a dispersant polymer, comprising: (a) 50 to 95 wt %, based on weight of the dispersant polymer, of structural units of a monoethylenically unsaturated monocarboxylic acid monomer; and (b) 5 to 50 wt %, based on weight of the dispersant polymer, of structural units of a sulfate bearing ethylenically unsaturated monomer.
