I think as society we better educate ourselves on every little ingredient that we our bodies. Petroleum has no place in our body. The cosmetic companies putting toxins in the Makeup, Lotions, Creams, and Hair Products, shaving products, Lipsticks and Deodorants, Toothpaste and hundreds of other cosmetic and products that we use everyday. Dioxane is chemical petroleum and widely used by the Deodorant. This chemical contaminants known to cause skin cancer. I strong advice to avoid any skin care product which made petroleum.
