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 Ris independently selected from a hydrogen and a &#x2014;CHgroup; and 2 to 40 wt % of structural units of formula II wherein each Ris independently selected from a &#x2014;Calkyl group and wherein each Ris independently selected from a hydrogen and a methyl group.

Automatic dishwashing formulation with dispersant copolymer

Disclosed is an improved method for the preparation of highly pure haloformimine compounds in high yields by reacting a formimine compound in a solvent with a halogenating agent while maintaining the pH of the halogenation reaction in the range of 2 to 5. The pH of the reaction may be maintained by a variety of means, such as by the addition of a base.
