Comparing Shampoos, Looking for Advice.
Soapmaking is at its heart, a science. When we add colors and fragrance to the process, we turn the science into an art. Each oil has its own saponification value, or the amount of lye it takes to turn 1 gram of oil into 1 gram of soap. When we make cold process soap, it’s a mathematical formula that looks like this: (Oil Amount) x (SAP value) = Lye Amount needed. For a real example, it looks like this (10 oz. Olive Oil) x (.134) = 1.34 oz. lye. So, it takes 1.34 ounces of lye to turn 10 ounces of Olive Oil into soap. Using the exact amount of lye you need to make the exact amount of soap with nothing left over (no extra oils) is called a 0% superfat or a 0% lye discount.
Many soapmakers like to have some extra oils in their soap that are leftover and not bound to lye. Any extra oil left in the soap and not attacked by the lye is called a ‘superfat.’ The terms ‘superfat’ and ‘lye discount’ can be used interchangeably
superfatted simply means more oils re used then are broken down into soaps by the lye
