Hi Everyone! After reading this entire thread about tooth soap, I decided to share my experience. I have used my own tooth soap for over 2 years now, and have a whiter smile than ever before. Love how clean my teeth feel. I am allergic to toothpaste from the store. My insides of my cheeks would literally peel off after every brush! Anyway, recently I ventured into liquid soap making. I made a cold process 100% coconut milk liquid soap made from mostly olive oil and castor oil. It does have 5% coconut oil in it. I put a small amount of this into a squeeze bottle and it works wonderful as a tooth paste! I did scent it with a few drops of peppermint eo. I say whoever wondered if you could use KOH and make a liquid version, GO FOR IT! I like it a lot better! Byrdi
