I have a friend who produces bio diesel and glycerin is a by-product of the process. After the ethanol evaporates off it has a lard consistancy and lathers and clean quite well.
My question is what quanity of lye to glyerin is needed? Original oil is deep fryer oil.
Answer:
Sorry Chuck but I don't know anything at all about making soap from bio diesel glycerin.
Hopefully a reader will be able to point you in the right direction.
