Claim:
1. A phosphate-free dishwashing composition, comprising: 5 to 99 wt % of a builder; 0.1 to 15 wt % of a surfactant of Formula 1, Formula 2, or a combination thereof, wherein R 1 is a C 8 -C 24 alkyl group, R 2 is a C 1 -C 5 alkyl group, R 3 is hydrogen, a C 1 -C 12 alkyl group, a C 1 -C 12 arylalkyl group, or a group represented by the Formula 3, wherein E is a C 1 -C 8 alkylene group or an oxygen atom, and R 4 is a C 1 -C 8 alkyl group, m is a number between 1 and 100, and n is a number between 0 and 50, and R 0.05 to 5 wt % of a first polymer having a weight-average molecular weight between 35,000 and 100,000 g/mol and comprising 0.5 to 10 wt % of a dispersant comprising a second polymer having a weight-average molecular weight between 1,000 and 30,000 g/mol and comprising 50 to 100 wt % of monoethylenically unsaturated C wherein the phosphate-free dishwashing composition comprises less than 0.5 wt % of a phosphate-containing compound, based on a total weight of the dishwashing composition.
