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.
