IMPORTANT DATA
Physical State; Appearance ODOURLESS WHITE SOLID IN VARIOUS FORMS Occupational exposure limits TLV not established. MAK: (Respirable fraction) 1.5 mg/m³ (DFG 2004).	Routes of exposure The substance can be absorbed into the body by inhalation. Inhalation risk Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
