EXPOSURE & HEALTH EFFECTS

Routes of exposure
 

Effects of short-term exposure
Ingestion could cause effects on the gastrointestinal tract. 

Inhalation risk
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly. 

Effects of long-term or repeated exposure
