Monkey Butt?

Via Frank Martin I've come across this product called Anti Monkey Butt Powder. Turns out that motorcyclists call the butt rash you can get from sitting on your bike for too many hours "monkey butt" cause you have to walk like a monkey. They say this product will help bicyclists too, but their website gives no hint as to the contents of the product. I'm sure they don't want to give away all of their competitive advantage, but howzabout a vague idea. Talcum? Arsenic? Cornstarch? Orange blossoms? Ganges mud?
