Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 33.3 µg/cm²
- Most sensitive endpoint:
- sensitisation (skin)
DNEL related information
- DNEL derivation method:
- ECHA REACH Guidance
- Overall assessment factor (AF):
- 37.5
- Dose descriptor:
- other: LOAEL (expressed in µg/cm²)
- Value:
- 1 250 mg/m³
- AF for dose response relationship:
- 3
- Justification:
- LOAEL is used as starting point
- AF for differences in duration of exposure:
- 1
- Justification:
- time-scaling is not appropriate when the toxic effect is mainly driven by the exposure concentration
- AF for interspecies differences (allometric scaling):
- 1
- Justification:
- not applicable for local effects
- AF for other interspecies differences:
- 2.5
- Justification:
- default value
- AF for intraspecies differences:
- 5
- Justification:
- worker population
- AF for the quality of the whole database:
- 1
- Justification:
- no need for further assessment factor
- AF for remaining uncertainties:
- 1
- Justification:
- no need for further assessment factor

No consumer use is foreseen for this substance. However, as exposure for humans via the environment via inhalation, dermal and oral route is considered as relevant, it was checked if DNELs had to be derived for this population. As no hazard is observed after exposure via the oral or inhalation, a DNEL derivation for these routes is not needed for man via the environment.
In addition, although a qualitative assessment for local effects after short-term exposure via the dermal route and a quantitative assessment for local effects after long-term exposure via de dermal route have been performed for the worker population based on hazard data from a local lymph node assay, these DNELs are not considered relevant for the population man via the environment and were therefore not derived.
