Predicted bar properties
Predicted from the fatty acid profile of the oils, the same way the calculator scores a recipe. The right-hand figures are the usual cold process ranges; green bars fall inside them.
Reading the numbers
- •Cleansing sits at 20, inside the 12 to 22 range most makers aim for.
- •Hardness is 42, a solid bar without being brittle.
Making it
Add 1-2 tbsp pumice powder or dried coffee grounds per pound of oils at medium trace. The high castor boosts lather. Lower superfat allows stronger cleaning action.
