Abstract
The present invention is in the field of machine dishwashing compositions. More particularly, it relates to machine dishwashing compositions comprising a phosphonate and polycarboxylate comprising acrylic acid monomers. The invention also relates to a method of washing kitchenware in a machine dishwasher with a machine dishwashing composition comprising a phosphonate and a polycarboxylate comprising acrylic acid monomers and a process for making said composition.
Claims15
