Soap ingredient calculator

A soap calculator, what is it for and how does it work?

It’s important to calculate how much caustic soda you need for the saponification of the oils and fats that you want to use. Too much caustic soda might cause skin irritation as not all caustic soda has reacted with the fats and oil. Too little and your soap will work as well. You can calculate precisely how much you need of every ingredient using a soap calculator.
