Patent ID: 7985724

Claim:
A detergent composition for hard surface, comprising: (A) a monoalkyl glyceryl ether whose alkyl group has 3 to 8 carbon atoms, (B) a compound represented by the following formula (1): R 1 (OR 2 ) m OH (1) wherein R 1 is a C2 to C6 alkyl group, m is a number of 1 to 4, and R 2 is a C2 or C3 alkylene group, (C) monoethanolamine, (D) citric acid, 0.1 to 5% by mass of (E) at least one surfactant selected from the group consisting of the following (IV) to (V): (IV) an alkyl glycoside represented by the following formula (6): R 30 (OR 31 ) x G y (6) wherein R 30 represents a C8 to C18 linear or branched alkyl or alkenyl group or an alkyl (C1 to C6) phenyl group, R 31 represents a C2 to C4 alkylene group, G represents a residue derived from a reducing sugar having 5 to 6 carbon atoms, x represents a number of 0 to 5 on the average, and y represents a number of 1 to 10 on the average; (V) an alkylamine oxide represented by the following formula (7): wherein R 40a represents a C8 to C16 linear alkyl or alkenyl group, R 40c and R 40d each represent a C1 to C3 alkyl or hydroxyalkyl group; R 40b represents a C1 to C5 alkylene group; A represents a group selected from the group consisting of —COO—, —CONH—, —OCO—, —NHCO—, and —O—, and p is a number of 0 or 1; and water, wherein: the mass ratio of (A) to (B) is (A)/(B)=0.2 to 5, the total content of (A) and (B) is (A)+(B)=1 to 15% by mass, the mass ratio of (C) to (D) is (C)/(D)=5 to 30, the total content of (C) and (D) is (C)+(D)=2 to 7% by mass, provided that (D) is calculated as acid form, and the pH of the detergent composition at 20° C. is 9.5 to 11.5.
