Abstract:
An automatic dishwashing composition is provided including a dispersant polymer; a builder; and a surfactant, wherein the surfactant is a fatty alcohol alkoxylate of formula I: wherein R1 is a linear or branched, saturated C8-24 alkyl group; R2 is a linear saturated C2-8 alkyl group; m has an average value of 22 to 42; n has an average value of 4 to 12; wherein m+n is an average value of 26 to 54; wherein the fatty alcohol alkoxylate has an average ethyleneoxy unit concentration per molecule, X, of >45 wt %; and, wherein the fatty alcohol alkoxylate has a ratio, Z, equal to X divided by n, wherein the ratio, Z, is
