DETERGENT COMPOSITION FOR WASHING TABLEWARE

PROBLEM TO BE SOLVED: To provide a detergent composition for washing a tableware, exhibiting excellent detergency to stains which are lipids and proteins mixed, dried and adhered to a surface of a tableware, and to provide a method of washing the tableware using the same.SOLUTION: A detergent composition for washing a tableware contains: (A) a compound represented by general formula (1); (B) a copolymer including a constitutional unit derived from carboxylic acid having a reactive unsaturated group and 3 to 6 carbon atoms or (b-1) a salt thereof, and a constitutional unit derived from (b-2) olefin having 2 to 12 carbon atoms; and (C) a polymer other than(B) the component, including a constitutional unit derived from maleic acid or a salt thereof. Here, a content of (A) the component is 0.1 to 50 mass%, a content of (B) the component is 0.1 to 20 mass%, a content of (C) the component is 0.1 to 25 mass%, a mass ratio ((A)/[(B)+(C)]) of (A) the component to the total of (B) the component and (C) the component is 0.1 to 10, and a mass ratio ((B)/(C)) of (B) the component to (C) the component is 0.1 to 2.5.
