DI(2-ETHYLHEXYL) PHTHALATE ICSC: 0271
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO LIGHT COLOURED VISCOUS LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing irritating fumes. Reacts with strong oxidants acids, alkalis, and nitrates.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/m; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: 10 mg/m; Peak limitation category: II(8); Carcinogen category: 4; Pregnancy risk group: C; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the testes. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
