Dr Bronner's embraces quackery outright, as to what degree it was intentional originally it's a mystery, the founder had a troubled background as a Jew escaping Nazi Germany, and went to the US to found a pacifistic cult around castile soap, that had actual followers.
Anyway, I find it's very good on the skin, I guess that them selling somewhat fancy soap as overpriced floor cleaner just adds to the mystique.
