Becky explains the difference between a beauty bar and cleansing bar soap. She explains what saponification is. A lot of people ask if you can use a beauty bar for making home made laundry soap. The answer is no. A beauty bar is a superfat recipe, that means there is extra oil left over in the bar to nourish your skin when you use it. To make home made laundry soap you need to use a cleansing bar which is a soap recipe that is perfectly even so when it saponifies there is no extra oil left over, a cleansing bar is more “dry”.
