I am having a little difficulty getting my mind around adding lye to an emulsion. How much are we talking about here? Say, I have a small batch of 8 oz, and my pH reading is around 3. (This has happened to me.) Would you add a just a few crystals? And why would this not be irritating to the skin? Would the lye change the consistency of the emulsion? Thanks in advance. a Quote Link to comment Share on other sites More sharing options...
