Abstract

A process for preparing a storage-stable and free-flowing concentrated water-based liquid detergent containing 15 to 35% by weight of anionic surfactant, 20 to 35% by weight of nonionic surfactant, and from 5 to 20% by weight of alcohol. A dilute sodium hydroxide solution is heated to 70.degree. to 85.degree. C. to which is added a fatty acid and the alcohol. The mixture is stirred at 350 to 500 r.p.m. for 3 to 10 minutes. The anionic surfactant and nonionic surfactant are added to the mixture and stirred at 150 to 350 r.p.m.
