EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol. 

Effects of short-term exposure
 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Tumours have been detected in experimental animals but may not be relevant to humans. 


Occupational exposure limits
 

ENVIRONMENT
 

NOTES
Other melting points: between -40°C and -46°C.
The recommendations on this Card also apply to 1,2-Benzenecarboxylic acid, di-C8-10-branched alkyl esters, C9-rich (CAS 68515-48-0) (DINP 1 is a trade name).
