Lye Calculator™

January 2010 Added Butterfat to the calculator. The saponification value is for butterfat with no milk solids or water content. February 2004 We have adjusted the water to give a range of values. In the past the water was calculated at 6 fl oz per pound of fats. We are now offering 4 to 6 fl oz per pound of fats. If you want the same amount as before use the higher number. If you need to reduce the water in your soap quickly for packaging purposes then you may reduce the water to the lower amount, or anywhere in between. Best! MMS Staff
