I agree with the superfatting post. I superfat at 7% and sometimes higher and find these to be gentle. I recently participated in a soap swap and I could easily guess those that had a lower superfat, they dried out my skin.
I personally dont think you need loads of expensive butters to create a 'moisturising' bar, but I do use shea and cocoa butter and love how my skin feels, I think it adds a little extra. I recently tried a bar with Jojoba (not mine) - OMG it was delish, silky smooth and left my skin feeling great. However if your superfat was low - this would defeat the purpose of adding these great oils - IMHO
As for Red - arggh, I have over coloured so many times trying to get it right. To little and it goes pink, too much and, like Carebear said = Psycho.
