I have some problem with the product - Fatty acid face soap (face wash)
1. The reaction between fatty acid (mysristic acid, stearic acid, lauric acid, etc) and KOH
What the ratio of mol between them should be?
How to know the reaction do end?
2. What shoud we consider when thickening the product by Carpobol aqua SF1 (Acrylate Copolymer)?
Thank for all!
