Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
23.5 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):
37.5
Dose descriptor starting point:
NOAEL
Value:
1 000 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
881.5 mg/m³
Explanation for the modification of the dose descriptor starting point:

in accordance with ECHA REACH TG R8 and ECETOC technical report 110. Inhalation long-term systemic DNEL based on NOAEL (OECD 407) in rats

AF for dose response relationship:
1
Justification:
in accordance with ECETOC technical report 110
AF for differences in duration of exposure:
3
Justification:
in accordance with ECHA REACH TG R8 and ECETOC technical report 110. Increasing exposure duration does not result in an increase in incidence and severity of adverse effects, based on comparable results from animal studies after repeated oral treatment lasting 14-days, 28 days and about 63 days. A reduced AF of 3 for exposure duration is considered sufficiently conservative.
AF for interspecies differences (allometric scaling):
1
Justification:
In accordance with ECHA REACH TG R8; Allometric scaling is not applied, AF not used for inhalation route.
AF for other interspecies differences:
2.5
Justification:
In accordance with ECHA REACH TG R8 and ECETOC technical report 110.
AF for intraspecies differences:
5
Justification:
ECHA REACH TGD
AF for the quality of the whole database:
1
Justification:
ECHA REACH TGD and ECETOC technical report 110
AF for remaining uncertainties:
1
Justification:
ECHA REACH TGD and ECETOC technical report 110

Route of original study:

DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:
no hazard identified
Most sensitive endpoint:

DNEL related information

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
6.7 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):
150
Dose descriptor starting point:
NOAEL
Value:
1 000 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:

The bioavailability of dermal routes are considered equal.


NOAEL (dermal) derived according to ECHA Guidance TGD R8: "Guidance on information requirements and chemical safety assessment", Appendix R.8-2, Example B.5.
Corrected NOAEL(dermal) = NOAEL(oral,rat) * Absorption(oral, rat)/Absorption (dermal, human)
= 1000 mg/kg bw * 100% / 100%
= 1000 mg/kg bw

AF for dose response relationship:
1
AF for differences in duration of exposure:
3
Justification:
NOAEL of 1000 mg/kg bw was obtained in the 14-day study, in the 28-day study and in reproduction toxicity screening test, in which animals were treated longer than 60 days. It is not likely, that the NOAEL will be far lower than 1000 mg/kg bw for the sub-chronic and chronic toxicity. No toxicologically significant changes noted in hematology, coagulation, clinical chemistry and urinalysis parameters. There were no test item-related effects in absolute and relative organ weights, gross and histopathology parameters in both the sexes in all studies.
AF for interspecies differences (allometric scaling):
4
Justification:
According to ECHA REACH TGD R8 and ECETOC technical report 110; Allometric scaling from
rat to human => factor of 2.5 for remaining interspecies differences not taken but included into intraspecies variability consideration.
AF for other interspecies differences:
1
Justification:
According to ECHA REACH TGD R8 and ECETOC technical report 110, factor of 2.5 for remaining
interspecies differences not taken but included into intraspecies variability consideration.
AF for intraspecies differences:
5
Justification:
According to ECHA REACH TGD R8 and ECETOC technical report 110; German Ausschuss für
Gefahrstoffe- AGS 2010
AF for the quality of the whole database:
1
Justification:
According to ECHA REACH TGD R8 and ECETOC technical report 110: Good /standard quality of
database.
AF for remaining uncertainties:
2.5
