Acute/short term exposure
Hazard assessment conclusion:
hazard unknown but no further hazard information necessary as no exposure expected
DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:

DNEL related information

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
5 mg/kg bw/day
Route of original study:
Dermal
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
200
Dose descriptor starting point:
NOAEL
Value:
100 mg/kg bw/day
Modified dose descriptor starting point:
NOAEL
Value:
1 000 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

Application of route-to-route extrapolation leads to a difference between oral and dermal absorption (100% versus 10%). This leads to an increase of the NOAEL for systemic effects after dermal exposure with a factor 10.

AF for dose response relationship:
1
Justification:
reliable dose responses found for both the acid and amine parts
AF for differences in duration of exposure:
2
Justification:
based on a 90-day toxicity study with the amine
AF for interspecies differences (allometric scaling):
4
Justification:
study in rat
AF for other interspecies differences:
2.5
Justification:
remaining differences default
AF for intraspecies differences:
5
Justification:
worker exposure considered
AF for the quality of the whole database:
2
Justification:
The data available are of sufficient quality to allow a derivation of a DNEL, but no data on the compound are available.
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.027 mg/cm²
Most sensitive endpoint:
skin irritation/corrosion
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
30
Dose descriptor:
other: NOAEL in 28 day dermal study 0.8 mg/cm2
AF for dose response relationship:
1
AF for differences in duration of exposure:
6
Justification:
subacute to chronic
AF for interspecies differences (allometric scaling):
1
Justification:
no specific species differences expected
AF for other interspecies differences:
1
Justification:
no specific species differences expected
AF for intraspecies differences:
5
Justification:
extrapolation for worker exposure
AF for the quality of the whole database:
1
Justification:
data available are adequate
AF for remaining uncertainties:
1
Justification:
worst case by using the data on the amine part
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
