Solubility in water: none
EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation and by ingestion.
Effects of short-term exposure May cause mechanical irritation to the eyes.
Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly , especially if powdered.
Effects of long-term or repeated exposure
