According to the Durango Herald [1], "Most toothpaste, skin lotions, sunscreens, shampoos, conditioners, soaps and cosmetics contain toxic substances you do not want in your body. All of these products also end up in our waterways to affect us a second time when we use the water." More product information is available at the Cosmetic Safety Database [2].
