No, it's not bad to use...your soap will be fine so take a deep breath and relax

I've done some digging around, and including the comments on that product page for Rooto and Millers site all are saying it's 100% Sodium Hydroxide....{http://www.millersoap.com/soapingred.html}
Can you check your ingredients label on your can and see what it says? Not because its 'bad'..but Im curious what it says since the product page in that link doesn't show the back of the can

I checked mine and the one I have is 100% lye. Its not the one posted above that's a "lye based formula"
