Superfat vs lye discount the difference to know http://curious-soapmaker.com/superfat-vs-lye-discount.html How to calculate the hot process superfat http://curious-soapmaker.com/how-to-calculate-the-hot-process-superfat.html

I don't think you understand my question, I don't mean drop the lye discount to 2.3% using the original recipe so it calculates correctly. Let me try and explain. This is your updated recipe with Stearic Acid NF but entered into soapcalc as palmitic, stearic and myristic acids giving a SAP...

I don't know if your aware but your superfat oils (50% of the Shea butter and 50% of the Lanolin) that you add after passing the zap test and cooking for two hours, after all the lye has reacted with the oils, are included in you lye calculation. As the superfat oils are put to one side and not...

Stearic acid cas 57-11-4 seams to be a broad description of stearic acid products with multiple composition / grades / purity. Suppliers are not clear in their descriptions at all about what you are going to purchase, you do need to be checking product descriptions / MSDS for composition (high...

I'm just a bit confused about the stearic acid in part 2, CAS 57-11-4 which is solely octadecanoic acid and you provide a link to a company who sells it. If you follow that link and check the MSDS for that product its composition is Hexadecanoic Acid 59%, Octadecanoic Acid 40%, Tetradecanoic...
