PURPOSE:To provide a neutral liquid detergent composition having a high concentration of 60 to 90wt.% surfactant concentration and keeping a relatively high viscosity even when diluted to a concentration for general use. CONSTITUTION:This detergent composition contains 60 to 90wt.% surfactant components composed of 10 to 50wt.% straight-chain alkylbenzenesulfonic acid ethanol amine salt and 10 to 55wt.% fatty acid alkanol amide, 5 to 15wt.% viscosity reducing agent composed of one or more kinds of ethanol, PG and PEG and a viscosity modifier composed of one or more kinds of sodium chloride, sodium sulfate and a betaine-type amphoteric surfactant in an amount of 0 to 3.5wt.% based on the surfactant components. The amounts of the viscosity reducing agent and the viscosity modifier are adjusted so as to have gamma500cP viscosity at 25 deg.C and form a diluted aqueous solution having 70 to 400cP viscosity at 25 deg.C when diluted to 15wt.% concentration of the surfactant components. A nonionic surfactant may be contained. |
