Abstract:
The present invention is directed toward a detergent composition including (a) in total in the range of from 4.0% to 25.0% by weight of at least one organic chelating agent selected from methyl glycine diacetic acid (MGDA), glutamic acid diacetic acid (GLDA), the alkali metal salts of methyl glycine diacetic acid (MGDA) and glutamic acid diacetic acid (GLDA), referring to the total solids content of the respective detergent composition, and (b) at least one enzyme selected from proteases. The present invention is also directed toward the use of the detergent composition for laundry care and for automatic dishwashing, and to a process for manufacture of the detergent compositions.
