You're most welcome, glad that I could help in any way at all :) My math was wrong anyway. I suppose that creating a 1.5% solution in your soap has to do with what the volume of soap is, in the first place. If you see the infomercials about Proactive and then Murad - they sound like they are the same, but they're completely different things. Dr. Murad is a dermatologist/scientist, since his name is out front, I tend to trust his research more.
I'm glad that today is a better day! *hugs* carrie
