Automatic dishwashing detergent

A phosphate-free dishwashing composition, comprising:

• 5 to 99 wt % of a builder;
• 1 to 8 wt % of a surfactant of Formula 1,
• R1O—(CH2CH2O)m—(CH2CHR2O)n—R3 (1),
• wherein R1 is a C8-C24 alkyl group, R2 is a C1-C5 alkyl group, R3 is hydrogen, m is a number between 10 and 30, and n is a number between 0 and 8;
• 0.05 and 1 wt % of a first polymer having a weight-average molecular weight between 35,000 and 100,000 g/mol and comprising
• 22 to 80 wt % of monoethylenically unsaturated C3-C6 carboxylic acid units, and
• 20 to 78 wt % of C1-C12 alkyl acrylate units;
• and
• 1 to 8 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 C3-C6 carboxylic acid units;
• 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.

A method of manufacturing a dishwashing composition, the method comprising contacting

• 5 to 99 wt % of a builder;
• 0.1 to 15 wt % of a surfactant of Formula 1, Formula 2, or a combination thereof,
• R1O—(CH2CH2O)m—(CH2CHR2O)n—R3 (1),

• wherein R1 is a C8-C24 alkyl group, R2 is a C1-C5 alkyl group, R3 is hydrogen or a C1-C12 alkyl or arylalkyl group or a group represented by the Formula 3,
• —CH2CH(OH)CH2-E-R4, (3),
• wherein E is a C1-C8 alkylene group or an oxygen atom, and R4 is a C1-C8 alkyl group,
• m is a number between 1 and 100, and n is a number between 0 and 50, and R5 is a C1-C8 alkylene group;
• 0.05 and 5 wt % of a first polymer having a weight-average molecular weight between 35,000 and 100,000 g/mol and comprising
• 22 to 80 wt % of monoethylenically unsaturated C3-C6 carboxylic acid units, and
• 20 to 78 wt % of C1-C12 alkyl (meth)acrylate units;
• and
• 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 C3-C6 carboxylic acid units;
• wherein the dishwashing composition comprises less than 0.5 wt % of a phosphate-containing compound, based on a total weight of the dishwashing composition.
