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
The substance decomposes on burning producing toxic and irritating fumes (phthalic anhydride, ICSC 0315). Reacts with strong oxidants.

Occupational exposure limits
TLV: 5 mg/m³ as TWA (ACGIH 2001).

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