ACS -- Dozens of children’s bath products are contaminated with formaldehyde and 1,4-dioxane, both considered probable human carcinogens by the U.S. EPA, according to a study published by the nonprofit Environmental Working Group. No More Toxic Tub documents that more than 60% of 48 popular products tested, including Johnson’s Baby Shampoo and Sesame Street Bubble Bath, contained one or both of the toxic chemicals.
