Diethanolamine and Triethanolamine (DEA & TEA)
These ingredients function as foaming agents and emulsifiers, while irritating to the skin. They have also been revealed as possible carcinogens. The major concern with DEA/TEA is they combine with nitrites in beauty products to form carcinogenic compounds. Companies don’t have to label nitrites, so you have no way of knowing if your mascara or body wash contains them. Again this is the reason to use products from companies you can trust to have your well being in mind.
