and
through the skin.
Inhalation Risk:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.
Effects of Short-Term Exposure:
The substance
is mildly irritating to
the eyes
,
the skin
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
