PROBLEM TO BE SOLVED: To obtain a water-base neutral detergent which does not contain an arom. carboxylic acid, is a stable liq., and is excellent in degreasing and permeating properties even at a temp. higher than the cloud point by combining an alkanolamine, specific nonionic surfactants, and an aliph. carboxylic acid. SOLUTION: This detergent has a pH of 6-8.5 and contains 1-20wt.% alkanolamine, 10-30wt.% nonionic surfactant which comprises an ethylene oxide adduct of a 10-14C linear sec. alcohol and of which the average number of moles of ethylene oxide added is 5-10, 1-20wt.% nonionic surfactant which comprises an ethylene oxide/propylene oxide adduct of a 10-14C linear sec. alcohol and of which the average number of moles of ethylene oxide added is 5-9 and the average number of moles of propylene oxide addedd is 4-8, 1-20wt.% 6-12C aliph. carboxylic acid, and water. |
