Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
88 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):
5
Modified dose descriptor starting point:
NOAEC
Value:
441 mg/m³
Explanation for the modification of the dose descriptor starting point:

Undertaken as described in REACH Guidance R.8

AF for dose response relationship:
1
Justification:
Default factor, in accordance with REACH Guidance R.8
Justification:
Not applicable, NOAEL based on chronic data
Justification:
Not applicable (scaling addressed in route to route extrapolation) in accordance with REACH Guidance R.8
Justification:
The toxicity of metal complexing agents, of which this substance is an example, is associated with their ability to complex metals and either enhance their excretion or prevent their absorption. They are not metabolised and are rapidly excreted. As such there are likely to be no ‘Toxicodynamic’ differences between animals and humans that would justify use an addition factor
AF for intraspecies differences:
5
Justification:
Default factor, in accordance with REACH Guidance R.8
AF for the quality of the whole database:
1
Justification:
Default factor, in accordance with REACH Guidance R.8
AF for remaining uncertainties:
1
Justification:
Default factor, in accordance with REACH Guidance R.8
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
Most sensitive endpoint:
acute toxicity
Route of original study:
By inhalation
DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
10 mg/m³
Most sensitive endpoint:
irritation (respiratory tract)
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
Most sensitive endpoint:
acute toxicity
DNEL related information

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
no hazard identified
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified
DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:
no hazard identified
Acute/short term exposure
Hazard assessment conclusion:
no hazard identified

Workers - Hazard for the eyes

Local effects

Hazard assessment conclusion:
medium hazard (no threshold derived)

Additional information - workers

DNEL derivation for each of the relevant endpoints was based on the most conservative value obtained from available animal toxicity studies and the application of relevant assessment factors.
