Can denatured alcohol be substituted for ethyl alcohol to produce a “lye” solution used to create soap?
It depends on what it is denatured with. Some denatured alcohol merely has a small concentration of bitter (denatonium) or foul smelling substances, which will not interfere with soapmaking. Other may have other alcohols added which would probably work, too, but still others may have acetone and other ketones.
