<P>PROBLEM TO BE SOLVED: To provide a method for producing a liquid detergent composition which is excellent in productivity, and can neutralize high concentration fatty acids in a short time, in production of a liquid detergent composition mainly comprising higher fatty acid salts and giving rich and creamy foam. <P>SOLUTION: A method for producing a liquid detergent composition containing 25-40 mass% higher fatty acid salts in total includes: a step (1) of neutralizing and dissolving higher fatty acids having a melting point of 35°C or lower, in an aqueous alkaline solution at a temperature higher than the melting points of the higher fatty acids; and a step (2) of neutralizing and dissolving higher fatty acids having melting points exceeding 35°C, in the solution obtained in the step (1) at 80-85°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
