AF for differences in duration of exposure:
6
AF for interspecies differences (allometric scaling):
1
AF for other interspecies differences:

Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.4 mg/kg bw/day
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
0.2
DNEL extrapolated from long term DNEL
Explanation for the modification of the dose descriptor starting point:
DNEL is extrapolated from long-term DNEL.
AF for dose response relationship:
0.2
Justification:
In the study, the NOAEL was derived from the Medium dose group. No additional effects were observed in the high dose group. An acute dermal toxicity study on a structural analogue did not show acute toxicity.

Local effects

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