Abstract
The present invention provides a process for mixing water soluble salts of long chain (C.sub.8 to C.sub.22) monocarboxylic acids and water soluble acyl (C.sub.8 to C.sub.22) isethionates whrein the two materials are mixed and subjected to temperatures in the range from about 55.degree. C. up to about 90.degree. C. under conditions of shear. Preferably the materials are mixed in particulate form. The weight ratio of monocarboxylic acid salts to isethionates is preferably in the range of from 10:90 to 95:5. Suitably the present process is performed by use of a cavity transfer mixer. The product of the present process can have a smooth feel both initially and during use.
