Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

DNEL related information
Local effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 3.83 µg/m³
- Most sensitive endpoint:
- irritation (respiratory tract)
DNEL related information
- DNEL derivation method:
- ECHA REACH Guidance
- Overall assessment factor (AF):
- 75
- Dose descriptor:
- NOAEC
- AF for dose response relationship:
- 1
- Justification:
- Use of a NOAEC of 0.287 mg/m3 available in the key study used.
- AF for differences in duration of exposure:
- 6
- Justification:
- Use of a subacute study to assess a long-term DNEL
- AF for interspecies differences (allometric scaling):
- 2.5
- Justification:
- Allometric scale is not relevant for local effects according to REACH guidance
- AF for intraspecies differences:
- 5
- Justification:
- Only workers are exposed to the substance.
- AF for the quality of the whole database:
- 1
- Justification:
- Good quality of the database.
