I have a question regarding petroleum based laundry detergent and non-petroleum based detergent. Does popular liquid and powder detergent contain petroleum or only powder? Do the petroleum required to make detergent actually come from raw petroleum or is it a byproduct of the gasoline industry? I guess my question boils down to--Does my use of a petroleum based laundry product create a demand for oil or is it coming from another source? Also, with the price of oil skyrocketing--does that also affect the price of laundry detergent? I haven't seen any press on the issue.
