You have to use at least minimum water required in a soap calc for the lye to dissolve. Otherwise you will end up with undissolved lye crystals in your soap with dire consequences. Water is used as a carrier and it is needed for handmade soaps.Pentazole said:Ok of course I know that commercial toilet soaps are made in a different way than CP soap, and I wasn't recommending that anyone makes CP soap using alcohol as solvent I was just trying to make the point that water is not needed for saponification, that's all. The fact that plain old alcohol CAN be used, means water is only added for convenience.
I live in a country where it's so humid that my dishes have to sit in the dish rack for two days to dry out. You can imagine that if I use 35% water in my soaps it would take 5 years for a bar to cure/dry. Therefore I'm a proponent of 10-15% water.
