SBM Crafters Advanced Soap Calculator
Advanced Soap Calculator [v2.3]
sbmcrafters.com
This calculator can be used to make Solid Soaps , Liquid Soaps , or Cream Soaps and can accommodate
mixed sodium hydroxide/potassium hydroxide (NaOH/KOH) soap types and water-only or water+alcohol methods.
Calculations take into account the typical impurities percentage found in NaOH and KOH supplies.
Initial fluids calculations are as per "Failor" methods if no alcohol initial batch content is specified.
Specifying an alcohol content by entering an alcohol percent concentration to be used
will switch to the SBMC evaporated alcohol method and fluid calculations.
Accuracy of this calculator has been verified to the SAP values as provided by our oils suppliers.
