Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Workers - Hazard via inhalation route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.12 mg/m³
Most sensitive endpoint:
repeated dose toxicity
Route of original study:
Oral
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
75
Dose descriptor starting point:
NOAEL
Value:
10 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
8.8 mg/m³
Explanation for the modification of the dose descriptor starting point:

NOAEL from the 28 day oral study in rats was 10 mg/kd/day. This dose descriptor was modified as per ECHA guidance chapter R.8 (2012).

AF for intraspecies differences:
5
AF for the quality of the whole database:
1
AF for remaining uncertainties:
1
Acute/short term exposure

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
0.03 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):
300
Dose descriptor starting point:
NOAEL
Value:
10 mg/kg bw/day
Modified dose descriptor starting point:
other: Route to route extrapolation (oral to dermal) was done as per ECHA guidance chapter R.8 (2012) to derive the corrected dermal NOAEL.
Value:
10 mg/kg bw/day
AF for dose response relationship:
1
AF for differences in duration of exposure:
6
AF for interspecies differences (allometric scaling):
4
AF for other interspecies differences:
2.5
AF for intraspecies differences:
5
AF for the quality of the whole database:
1
AF for remaining uncertainties:
1
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:
23.5 µg/cm²
Most sensitive endpoint:
sensitisation (skin)
DNEL related information
DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
100
Dose descriptor:
other: LLNA EC3 = 9.4% for Flunit was used as the dose descriptor. As per ECHA guidance , this EC3 was converted to a dose/area by multiplying by 250.The resulting value of 2350 µg/cm2 was then used as the dose descriptor for the Flunit dermal DNEL calculation.
AF for dose response relationship:
1
AF for differences in duration of exposure:
1
AF for interspecies differences (allometric scaling):
1
AF for other interspecies differences:
10
AF for intraspecies differences:
1
AF for the quality of the whole database:
1
AF for remaining uncertainties:
9
Justification:
An assessment factor of 3 was used for vehicle or matrix effect, and an assessment factor of 3 was used for exposure conditions.
