The performance of a multi-monomer sulfonated copolymers, Alcoguard 4160, was studied. It was found that Alcoguard 4160 showed excellent water film/water spot resistant performance, excellent anti-scaling properties for insoluble calcium and magnesium salts even in harsh condition such as using high hardness water. This product can effectively disperse kitchen soils and prevent it from re-attached to the matrix surface; hence it is excellent for hard surface cleaning especially in automatic dish wash detergents.
