Copolymers comprising polyalkylene oxide groups and quaternary nitrogen atoms

An automatic dishwashing cleaning composition including a dispersant polymer and a surface-modification surface-substantive polymer wherein the composition leaves glass after being washed with the composition in an automatic dishwasher with a contact angle with deionised water of less than about 50&#xb0; and wherein the surface-modification surface-substantive polymer has a rivulet forming effect on water drainage from glass.

Automatic dishwashing cleaning composition

The need for a liquid hard surface cleaning composition which provides reduced drying time is met by formulating the composition using copolymer comprising non-ionic monomeric units, a low level of cationic monomeric units, and other optional monomers.
