Abstract
An improved process for making a mild, detergent-soap, toilet bar containing a C6-C18 acyl isethionate as the principal surfactant in combination with minor proportions of C12-C20 fatty acids, a water soluble soap and water which comprises the step of forming a liquid mixture of said acyl isethionate, fatty acids and soap at a temperature of about 85.degree. C. to 105.degree. C. in the presence of about 0.5% to 2.5% by weight, based upon the bar, of vegetable oil prior to processing said liquid mixture on a chill roll to form particles which are further processed to yield said bar, said liquid mixture having reduced viscosity and being readily pumpable as compared to a liquid mixture prepared in the absence of said vegetable oil. The bar produced by the foregoing process also is part of the invention.
