In another thread I said I'd just about made everything I need for personal care except toothpaste and I wasn't sure I wanted to make toothpaste. Sort of seriously, I was kinda creeped out by the idea of homemade toothpaste. Then
@earlene linked me to a thread about tooth soap, which is apparently something people have done. I was intrigued. Now I'm doing a quick HP tooth soap experiment, a very small batch (SoapMaker said it was about $2 worth of ingredients) so not much of a risk. We'll see how it works out.
10% Shea Butter
60% Olive Oil
30% Babassu Oil
Plus a capsule of activated charcoal. I started by looking at
@Misschief's recipe, but I adapted it for what I have on hand. Shea instead of cocoa butter. I doubled the olive since I don't have any peanut oil. And I used babassu instead of PKO, gives you similar fatty acids without using coconut 'cause Misschief said coconut soap tastes nasty. I also did 3.5:1 KOH:NaOH, I think the others who tried this all used NaOH and made a bar, but I'm going to try making it a paste sort of like my shave soap where I put it in a jar and rub with a damp brush to lather.
Worst case scenario is that I put it in my mouth, poison myself, and die. Sounds like fun.
