Beschreibung
Zusammenfassung:	The present invention relates to a zero-phosphate machine dish wash composition in unit dose format comprising non-phosphate builder, alkali percarbonate, a manganese bleach catalyst in relatively low amounts and one or more polycarboxylate polymers. The builder comprises one or more from methylglycine-N,N-diacetic acid and/or one or more salts thereof, citric acid and/or one or more salts thereof, and glutamic acid-N,N-diacetic acid and/or one or more salts thereof. The polycarboxylate polymers have a weight average molecular weight of between 1000 and 100,000, the polymers comprising at least 20 mol-% of acrylate monomers and from 0 to 40 mol-% of maleate monomers. The composition provides improved tea stain removal upon use.
