Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Explanation for the modification of the dose descriptor starting point:

Default (DNEL calculator):

Starting point NOAEL 28-day on Oleyl tripropylenetetramine: 20 mg/kgbw/d; The corrected 8 hr inhalation NOAEC for workers with inclusion of correction from 7 day/week to 5 day/week for workers, is NOAEL(20 mg/kg) * 1.76 mg/m3 * 7/5 = 49.4 mg/m3. No factor 2 route extrapolation from oral to inhalation. Due to very low vp (< 4.7 x 10-5 Pa at 20°C), relevant exposure is only possible as aerosol or larger particles. If any inhalation does occur, this can only be in the form of larger droplets, as the use does not include fine spraying. Droplets will deposit mainly on upper airways, and will be subsequently swallowed following mucociliary transportation to pharynx. This results to no principal difference in absorption compared oral route.

Workers - Hazard via dermal route

Dose descriptor starting point:
NOAEL
Value:
20 mg/kg bw/day
Modified dose descriptor starting point:
NOAEL
Value:
28 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:

Default (DNEL calculator).

Starting point NOAEL 28-day on Oleyl tripropylenetetramine: 20 mg/kgbw/d with correction from 7 day/week to 5 day/week for workers is 7/5* 20 = 28 mg/kg bw/day. At this stage no data are available on dermal absorption. Polyamines are not expected to easily pass the skin in view of its ionised form at physiological conditions. However, as this is not quantitatively evaluated, 100% dermal absorption (i.e. similar as oral) is considered as worst case assumption.

Additional information - General Population

Consumers/general population will not be exposed.

These substances are only applied in industrial applications applying adequate PPE. 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.
