Abstract
Abstract A translucent detergent bar is provided containing with respect to the total weight of the bar 25 to 34 wt% soap, 5 to 15 wt% alcohol, 15 to 30 wt% sugar and/or cyclic polyol, and 15 to 30 wt% water, the soap comprising a soap mixture consisting of 18 to 26 wt% soluble soaps and 8 to 16 wt% insoluble soaps calculated with respect to the total weight of the bar. The bar has good user properties and yet can be a low cost bar due to its relatively low soap content.
