I don't know about you, but I don't need to do any research to understand what those ingredients are, well with the exception of tocopherol, which is a synonym for Vitamin E. Dr Bronners is also certified organic, not tested on animals, contains no animal derived ingredients, is also certified fair trade.
So the conclusion??? I think I will be paying the 4 extra dollars for Dr Bronners castile soap and even though my laundry will cost 4 cents/load rather than 1 cent/load, I am OK with that.
