I've been thinking about revisiting vinegar in my CP soaps. I've only used apple cider vinegar but was wondering what others use. White vinegar (ingredients: acetic acid and water) is much cheaper where I live. Is it just as good for soap making? My main reasons for using vinegar are hardening high OO soap and softer lather (I agree with @AliOop on this one ). What's your favorite vinegar to use in soapmaking?
