Separated from strong oxidants. 

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW VISCOUS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
Decomposes on burning. This produces toxic and irritating fumes (phthalic anhydride - see ICSC 0315). Reacts with strong oxidants. 

Occupational exposure limits
TLV: 5mg/m³ as TWA; (ACGIH 2001).
MAK: 0.05 ppm, 0.58 mg/m³; Carcinogen category: 4; Peak limitation category: I(2); Pregnancy risk group: C; (DFG 2009). 

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

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
