More Information
Summary:A method for removing stain or soil from laundry, including contacting the laundry with a laundry detergent composition including an aminocarboxylate builder or co-builder, a polymer, and a protease. The aminocarboxylate may be methylglycine diacetate (MGDA), iminodisuccinic acid (IDS), glutamic acid diacetate (GLDA), ethylenediaminedisuccinic acid (EDDS), polyasparatic acid, and associated salts. The polymer may be an ethoxylated polyethylenimin with an average molecular weight from 3,000 to 250,000 g/mol having 80 to 99% by weight ethylene oxide side chains, based on total ethoxylated polyethylenimine, and/or an ethoxylated hexamethylene diamine, quaternized and optionally sulfated with an average molecular weight from 2,000 to 10,000 g/mol. The disclosure further relates to the use of such compositions for removing stain or soil from laundry, to such laundry compositions themselves and their manufacturing process, as well as to methods of improving stain-removal ability of a protease in laundry detergent compositions.
