Important Data
|
Physical State; Appearance:
COLOURLESS LIQUID.
Physical Dangers:
Chemical Dangers:
The substance can presumably form explosive peroxides.
Reacts
with
strong oxidants
.
Occupational Exposure Limits:
EU OEL: 50.1 mg/m3 10 ppm as TWA (skin) (EU 2006).
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation,
through the skin
and
by ingestion.
Inhalation Risk:
No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
Effects of Long-Term or Repeated Exposure:
The liquid defats the skin.
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
