Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
DNEL related information
Explanation for the modification of the dose descriptor starting point:

As the long-term DNEL is normally sufficient to ensure that effects do not occur, and no acute effects were seen in the repeated dose study or acute studies, no acute hazards during short term exposure is expected, if long term DNELs are maintained.

Local effects

Long term exposure
Hazard assessment conclusion:
high hazard (no threshold derived)
Most sensitive endpoint:
sensitisation (skin)
Acute/short term exposure
Hazard assessment conclusion:
high hazard (no threshold derived)
Most sensitive endpoint:
