Liquid Castile Soap
Liquid Castile Soap! What a process…
I cooked it for 6 hours instead of the 3 to 4 the tutorial said. I was waiting for the stages I was supposed to see, and I still didn’t see all of them. But when I finally tested it to see if it was translucent, it was. So I assume it is done.
The soap-paste sat all night in distilled water to dissolve, but it didn’t. This morning, I ran it through the Vita-Mix on low speed in small batches to break up the very sticky clumps of soap-paste. Then I added more boiling distilled water to finally dissolve all the little clumps. They dissolved in another hour or two. I’ve got more than a gallon, for sure.
The final step remaining is to neutralize the KOH (Potassium Hydroxide) excess, which is about 10%. I don’t want to rely on the “about this much” method that the recipe uses. Instead, I will wait for Jeff, our resident chemist, to help me figure out exactly how much borax in solution I need to neutralize 1.16 ounces of KOH excess. He told me on the phone this morning that we’d have to do conversions involving ounces, grams, moles and possibly g/moles. I have a smidge of understanding, but no real idea of what to do. So I’ll wait for him, unless I can find a handy-dandy table on the internet somewhere to just give me the answer.
That’s that. It looks good, it smells good and I think pretty soon I can call it a success. I hope.
