摘要： An automatic dishwashing composition is provided, comprising: builder; nonionic surfactant; first 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; and second 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; wherein the first dispersant polymer and the second dispersant polymer are different.
