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.
