Synergistic protein soil removal through novel chelator combination

A concentrated detergent composition comprising:

• from 0.5 wt. % to 5 wt. % of a nonionic surfactant,
• at least 52 wt. % of an alkali metal carbonate, and
• chelating/sequestering agents, wherein the chelating/sequestering agents comprise of from 5 wt. % to 25 wt. % of methyl glycine diacetic acid, from 5 wt. % to 10 wt. % glutamic acid N,N-diacetic acid, and from 5 wt. % to 17 wt. % of an alkali metal tripolyphosphate;
• wherein the detergent composition removes protein soil;
• wherein the total quantity of the chelating/sequestering agents is less than 45 wt. % of the composition;
• and
• wherein the molar ratio of the glutamic acid N,N-diacetic acid to the sum of the methyl glycine diacetic acid and the alkali metal tripolyphosphate is 0.05 to 2 further wherein the wt % of each component is based on the total weight of the composition.
