PHOSPHATE-FREE LIQUID CLEANING COMPOSITIONS CONTAINING POLYMER

摘要

The present invention relates to alkaline, aqueous cleaning concentrates and cleaning solutions comprising a solution of an alkali metal hydroxide, an active chlorine source, water soluble copolymers of a monoethylenically unsaturated dicarboxylic acid and monoethylenically unsaturated monocarboxylic acid, water and optionally an alkali metal silicate. These cleaning solutions are useful for the cleaning of food soils, and more specifically, are useful for the removal of milk soils from cold and hot surfaces without the use of phosphate builders.
