Sometimes simply known as dioxane, 1,4-dioxane is a colorless, flammable liquid often used as a solvent or solvent stabilizer. It is a synthetic organic compound, meaning it does not occur naturally in the environment. Dioxane is used as a solvent, cleaning agent, chemical stabilizer, surface coating, adhesive agent, and an ingredient in chemical manufacture. Historically, dioxane was used as a stabilizer in chlorinated solvents, mainly for 1,1,1-trichloroethane (TCA). Currently, dioxane is also used as a solvent or solvent stabilizer in the manufacture and processing of paper, cotton, textile products, automotive coolant, cosmetics, shampoos and other products.
