1,4 dioxane has been getting a lot of press lately.  It has been called a likely cancer causing chemical and it is contained in many things that we use frequently. As a refresher, 1,4 dioxane is found in chemical solvents like trichloroethane or TCA, as a stabilizer and is used in the manufacture of chemicals, plastics, food additives and pharmaceuticals. It is also a contaminant produced in making surfactants, cosmetics, shampoos and detergents.
