A recent study by the Environmental Working Group found the 22% of all cosmetic products might be contaminated with cancer-causing impurities.  Among the 22 products, 15 are for babies and children.  One of the cancer-causing agents is called 1,4-dioxane and the study showed that it may be present in 57 % of all baby soaps and 34% in all baby lotions.  Another article suggested that para-dioxane in some children's shampoos was at a level higher than those recommended by the USDA.
