Abstract
1,4-Dioxane is commonly used as a solvent, cleaning agent, chemical stabilizer, surface coating, adhesive agent, and an ingredient in chemical manufacture. The IRIS Program completed the assessment for oral exposure to 1,4-dioxane on August 11, 2010 and noted that new inhalation studies would be evaluated separately. Additional information regarding 1,4-dioxane toxicity resulting from exposure via inhalation has now been incorporated into the 2010 assessment without changing the oral toxicity conclusions of the previous assessment.
