Stain removal method using granular detergent composition comprising magnesium salt

摘要

Built granular detergent compositions containing from 0.015% to 0.2%, based on weight of magnesium, of a water-soluble magnesium salt and 0.05% to 0.4% (acid basis) of ethylenediaminetetra(methylene phosphonic acid), diethylenetriamine penta(methylene phosphonic acid) or water-soluble salts thereof. The compositions deliver improved detergency at low wash temperatures.
