I'm hoping someone can help me out!
I've been reading about "salting out" glycerin from soap and I wondered, once the soap is skimmed off the top, how does one separate the glycerin from the nasty stuff and salt and so on? Like, my understanding is that there's going to be impurities and such in the water layer, so how would I get the glycerin without those impurities?
I'm looking to make glycerin myself out of my soap for using in various concoctions, and then use the glycerin-stripped soap for other purposes. I think I understand how to chemically separate them, but not physically separate them, if that makes sense?
Thanks!
