Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute toxicity
There is no C&L relevant hazard apparent after repeated exposure.
Local effects
Since no local effects were described, no local DNELs were derived.

General Population - Hazard via oral route
Systemic effects
Long term exposure
- Hazard assessment conclusion:
- DNEL (Derived No Effect Level)
- Value:
- 1.7 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):
- 100
- Dose descriptor starting point:
- NOAEL
- Value:
- 170 mg/kg bw/day
- Modified dose descriptor starting point:
- NOAEL
- Value:
- 170 mg/kg bw/day
- Explanation for the modification of the dose descriptor starting point:
- not required, no difference in oral absorption between rats and human is expected
- AF for dose response relationship:
- 1
- Justification:
- NOAEL used as starting point
- AF for differences in duration of exposure:
- 1
- Justification:
- exposure for complete pregnancy, no longer exposure possible
- AF for interspecies differences (allometric scaling):
- 4
- Justification:
- This factor describes the differences in metabolic rate between rats and humans based on body weight and is generally applicable to renally excreted substances.
- AF for other interspecies differences:
- 2.5
- Justification:
- Default factor for remaining differences
- AF for intraspecies differences:
- 10
- Justification:
- Default factor for consumers
- AF for the quality of the whole database:
- 1
- Justification:
- GLP guideline study
- AF for remaining uncertainties:
- 1
- Justification:
- NOAEL is already worst case due to wide spacing of doses
Acute/short term exposure
- Hazard assessment conclusion:
- no hazard identified
DNEL related information
General Population - Hazard for the eyes
Local effects
- Hazard assessment conclusion:
- no hazard identified
Additional information - General Population
Acute toxicity
A DNEL acute should be established for substances if an acute hazard toxicity (leading to C&L) has been identified and a potential for high peak exposures exists. Since DEHA is not classified for acute toxicity, a DNEL acute is not needed.
Local effects
Since no local effects were described, the DNELs are based on the systemic effects only
