Abstract: A solid composition comprising: a) from 25 to 88 wt. % free acid equivalent of non-crystalline chiral aminopolycarboxylate; and b) from 10 to 60 wt. % free acid equivalent of non-crystalline organic acid different from aminopolycarboxylate; and c) from 2 to 30 wt. % of water wherein the pH of a solution made by dissolving the solid in water in a 1:1 weight ratio is at most 10.0, as measured at 25 degrees Celsius.

Abstract: 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.
