Patent ID: 7268106

Claim:
An aqueous liquid detergent composition comprising: a plurality of long-chain fatty acid glycol esters represented by the following formula (1): R 1 COO(CH 2 CH 2 O) m A (1) wherein, R 1 represents a C 11-21 alkyl or alkenyl group, A represents a hydrogen atom or COR 2 (in which R 2 represents a C 11-21 alkyl or alkenyl group), and m stands for a number of from 1 to 3; and a surfactant, wherein the fatty acid constituent of the long-chain fatty acid glycol ester contains 65 to 85 wt. % of fatty acids having 18 or more carbon atoms, 15 to 35 wt. % of fatty acids having less than 18 carbon atoms, 35 wt. % or less of fatty acids having 16 carbon atoms, and 5 wt. % or less of fatty acids having less than 16 carbon atoms; and wherein the composition has a pH of from 1 to 5 at 25° C. when diluted to 20 times the weight with water.
