Abstract

Described are novel synthetic detergent base materials having a pH from 5 to 8 and consisting essentially of from 45 to 70 weight percent of mild synthetic surfactant, salts thereof, or a mixture of the mild synthetic surfactant and salts thereof; from 20 to 30 weight percent of C.sub.8 -C.sub.22 fatty acid; from 1.5 to 10 weight percent of C.sub.8 -C.sub.22 n-acyl sarcosine, salts thereof, or a mixture of the sarcosine and salts thereof; from 0.5 to 5 weight percent of C.sub.1 -C.sub.22 alkyl aryl sulfonic acid, salts thereof, or a mixture of the sulfonic acid and salts thereof; and from 1 to 5 weight percent soap, e.g., salts of C.sub.8 -C.sub.22 fatty acid. Also described are syndet bars prepared from the synthetic detergent base material.
