Okay so I've decided to make my first HP soap and I've never made 100% coconut. I understand that I am to use a 20% SF but I am unsure of what the lye concentration should be. I will be using a crockpot with a lid if that makes any difference. My other question is about salt. When people say they are adding salt to a soap is it usually dissolved in the lye water or is it added at trace like an exfoliant, or should I just leave the salt out all together. Does dissolving salt in the lye water add to the hardness of the soap, and how much PPO? Anyadvice would be greatly appreciated so just let me know. I am ready to soap!!!
