Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
0.123 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):
25
Dose descriptor starting point:
NOAEL
Value:
2.5 mg/kg bw/day
Modified dose descriptor starting point:
NOAEC
Value:
3.08 mg/m³
Explanation for the modification of the dose descriptor starting point:

Default (DNEL calculator). Starting point NOAEL 90-day on Tallow dipropylenetriamine: 2.5 mg/kgbw/d; The corrected 8 hr inhalation NOAEC for workers is NOAEL(2.5 mg/kg) * 1.76 mg/m3 = 4.4 mg/m3. A correction for exposure condition for 7 d/wk to 5 d/wk for workers has been applied. Leading to 6.17 mg/m3.

Justification:
Available data derived from valid studies showing consistent results between data.
AF for remaining uncertainties:
1
Justification:
Cross-reading to more studies on similar polyamine structures does not indicate additional concerns to be considered.

Explanation for the modification of the dose descriptor starting point:

Default (DNEL calculator)
Starting point is NOAEL 90-day on C12-14-Diamine: 0.4 mg/kgbw/d; The corrected 24 hr inhalation NOAEC for general population is NOAEL(2.5 mg/kg) * 1/1.15 mg/m3 = 2.17 mg/m3. An additional factor 2 has been applied for the route-to-route extrapolation from oral to inhalation.

Additional information - General Population

These substances are only applied in professional or industrial setting in asphalt applications applying adequate PPE. Use results to the inclusion into or onto a matrix. Consumers/general population will not be exposed.
However, to allow for evaluation from indirect exposures via the environment, DNELs have been derived for systemic toxicity from long term exposures via all routes.
