Dioxane is a colorless liquid ether used as a solvent and stabilizer for transporting chlorinated hydrocarbons. It is miscible in water but resistant to biodegradation and can leach into groundwater. Dioxane exposure through inhalation or skin contact may cause eye, respiratory, and central nervous system irritation and damage organs like the liver and kidneys. While low in toxicity to aquatic life, dioxane presents environmental hazards when it contaminates groundwater supplies.

4. Boiling point (101.1 °C).
5. Resistant to naturally occurring biodegradation
processes.

3. USES FOR DIOXANE ?
 Solvent for a variety of practical applications.
 Stabilizer for the transport of chlorinated
hydrocarbons.
 Used as an internal standard for nuclear magnetic
resonance.

4. PERMISSION EXPOSURE LIMITS
 Dioxane has an (PEL) 100 ppm (360 mg/m3) skin.
 Dioxane has an LD50 of 5170 mg/kg in rats.

5. HEALTH & ENVIRONMENTAL HAZARDS
 Cause irritating to the eyes and respiratory tract.
Exposure may cause damage to the central
nervous system, liver and kidneys.
 Has affected groundwater supplies, is highly
soluble in water, does not readily bind to soils, and
readily leaches to groundwater.
 Has low toxicity to aquatic life and can be
biodegraded via a number of pathways.
