I was in love with Sal Suds before I investigated all of the ingredients on the EWG website. Unfortunately the second ingredient "Coco-Betaine" aka, Cocamidopropyl betaine was voted 2004 ALLERGEN OF THE YEAR by American Contact Dermatitis Society. Dr. B. website states: Coco-Betaine: Mild and easily biodegradable, coco-betaine is formed by combining coconut fatty acids with betaine (a nature-identical synthetic so-named because it was first discovered in sugar beets). This foam-boosting cleansing agent buffers irritation caused by SLS.I was using Sal Suds for laundry, cleaning, dishes, everything, and I didn't mind the cost before I knew this information. Now I've reconsidered my devotion to the product and will no longer use :(
