Description
A toxic, colorless liquid with a slight ether-like smell. Dioxane is no longer recommended for use. In the past, it was used as a Solvent for Cellulose acetate, Ethyl cellulose, Benzyl cellulose, and other resins, oils, and waxes. It was often found in paint and varnish removers. Dioxane was also used as a Surfactant and Dispersant in textile processing, dyeing, and printing.
