Sodium Hexametaphosphate Reactions in Lye Soap
Does anyone have any advice/warnings on adding Sodium hexametaphosphate (NaPO3)6 to a cold process soap recipe? Cold process soap uses Lye (NaOH, aka Sodium hydroxide), and I was wondering if I could add Sodium hexametaphosphate as a lather enhancer/water softener, or would there be a bad reaction with the Lye? Any other possible dangers?
