    So guys, I heard so much about dual lye and wanted to try it out. I got extra pure KOH and the supplier claims its 99% pure. So, do I change the 90% to 99 in soapee?

    Hello Soapprentice, how much did the specific KOH cost?

    Where I live, I have been told that so high purity (>98) in KOH is very expensive and is used specifically for lab uses.
    The normal KOH purity that is affordable for soapmaking ranges from 85% to 92%.

    Can your supplier give you a CoA file for the specific KOH in order to see the purity that the manufacturer claims?

    If used for pharmaceutical manufacturing, yes, the KOH would be high-purity reagent grade. Lucky you!
