Is there lye in Woodspirits soaps?
All soap is manufactured using some sort of alkaline as a catalyst for the reaction of soap making [saponification] to occur. Hard bar soaps use sodium hydroxide, and liquid soap uses potassium hydroxide. When the process begins the new soap molecules begin to form and actually produce heat. When the process is complete there are no longer any molecules of oils or sodium hydroxide, but only molecules of soap. It is an irreversible process. So, even though lye is used in the process, the result is lye [alkaline] free.
