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).
OSHA PEL: TWA 5 mg/m3
NIOSH REL: TWA 5 mg/m3
NIOSH IDLH: 4000 mg/m3 See: 84742


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.
