As far as the smell goes, go ahead and try if you'd like. I personally would not bother as I would ALWAYS smell that nasty RPO funk. Adding a bit of AC to it might be interesting to see but I will warn you will still get an discoloring lather from soap with RPOWon't putting in FO or EO cover up the Red Palm's smell?
Is it that strong?
And regarding color, I am going to put Activated Charcoal so the color wouldn't be an issue.. i hope
