Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 4.7 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:
- 1 000 mg/kg bw/day
- Modified dose descriptor starting point:
- NOAEL
- Value:
- 1 400 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
There are no valid experimental data on repeated exposure by the dermal route available. Therefore, the worker-DNEL long-term for dermal route - systemic is derived from the NOAEL of 1000 mg/kg bw/day, obtained in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with a strucutral analogue in Wistar rats. The NOAELcorr. is calculated
as follows:
- absorption (oral, rat) = absorption (dermal, human)
--> modified dose descriptor (corrected dermal NOAEL) = 1000 mg/kg bw/day *(absorption (oral, rat) / absorption (dermal, human)) * (7 exposure days/week; rat / 5 exposure days/week; worker) = 1400 mg/m³
- AF for dose response relationship:
- 1
- Justification:
- ECHA REACH Guidance (starting point for the DNEL calculation is a NOAEL)
- AF for differences in duration of exposure:
- 6
- Justification:
- ECHA REACH Guidance (subacute --> chronic)
- AF for interspecies differences (allometric scaling):
- 4

- Modified dose descriptor starting point:
- NOAEL
- Value:
- 1 000 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
There are no experimental data on repeated exposure by the dermal route available. Therefore, the general population-DNEL long-term for dermal route - systemic is derived from the NOAEL of 1000 mg/kg bw/day,
obtained in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test with a strucutral analogue in Wistar rats. The NOAELcorr. is calculated
as follows:
- absorption (oral, rat) = absorption (dermal, human)
--> modified dose descriptor (corrected dermal NOAEL) = 1000 mg/kg bw/day *(absorption (oral, rat) / absorption (dermal, human)) = 1000 mg/m³

- Overall assessment factor (AF):

- Dose descriptor starting point:
- NOAEL
- Value:
- 1 000 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
The NOAEL of 1000 mg/kg bw/day, obtained in a combined repeated dose toxicity study with the reproduction/developmental toxicity screening test in Wistar rats, is used as dose descriptor starting point. As this as an study with oral substance administration, a modification of the starting point is not necessary.
