Patent ID: 8183196

Claim:
A neutral automatic dishwashing detergent composition comprising a) an acidifying particle comprising i) an aminocarboxylic builder, wherein the aminocarboxylic builder comprises from about 5% to about 80% by weight of the acidifying particle, and ii) an acidifying agent comprising a mineral acid selected from the group consisting of sulfuric acid, hydrochloric acid, and mixtures thereof; wherein the acidifying particle has a low hygroscopicity, a cake strength of at most 20N and a pH of from about 2 to about 6 as measured in 1% aqueous solution at 20° C.; and b) a polymer selected from the group consisting of a sulfonated polymer, a carboxylated polymer, and a mixture thereof; wherein the polymer comprises from about 0.1% to about 50% by weight of the detergent composition; and wherein the detergent composition has a pH from about 5 to 7.5 when dissolved in a weight ratio of 1:100 of the detergent composition to deionized water at 20 degrees Celsius.
