In order to ensure zero contamination, it has to be vacuum stripped and there is no way to know whether or not companies do this. A 1990 Danish study that assessed 76 personal care products: shampoos, body gels, soaps, etc. found 1,4-dioxane in 82% of the cosmetic products and 85% of the dishwashing products (4).
