Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
29 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):
18
Modified dose descriptor starting point:
NOAEC
Value:
529 mg/m³
Explanation for the modification of the dose descriptor starting point:
An OECD 422 combined 28-day/reproduction screening study with AAI-TEPA resulted to an overall NOAEL of 300 mg/kg/day. The corrected 8 hr inhalation NOAEC for workers is NOAEL (300) * 1.76 mg/m3 = 529 mg/m3. No factor 2 route extrapolation from oral to inhalation. Due to very low vp (< 0.00017 mPa at 25°C), exposure is only possible as aerosol. 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.
AF for dose response relationship:
1
Justification:
No specific concerns; starting point is NOAEL, effects at LOAEL are not severe and of local nature.
AF for differences in duration of exposure:
6
Justification:
The guidance indicates that for subacute to chronic a factor 6 should be applied. A lower factor could be considered as the females have been dosed for at least 43 days rather than 28 days.
AF for interspecies differences (allometric scaling):
1
Justification:
Already included in NOAEC calculation
AF for other interspecies differences:
1
Justification:
ECETOC reported in 2010 after an extensive review that there is no justification for the suggested additional factor of 2.5 for this, therefore a factor of 1 has been applied. As effects are interpreted as being local and related to the route of exposure (see comments), the already applied allometric scaling already represents a worst case.
AF for intraspecies differences:
3
Justification:
ECETOC reported in 2010 after an extensive scientific review that the appropriate fact for intra-species differences for workers is 3 and not 5. As the effects for which the risk assessment is made is based on a local response following an non-specific mechanism with expected inherently relative low variation between individuals, no additional factor is needed to accommodate for possible high uncertainty between individuals on the basis of possible specific sensitivities.
AF for the quality of the whole database:
1
Justification:
Available data derived from valid studies showing consistent results within category.
AF for remaining uncertainties:
1
Acute/short term exposure
Hazard assessment conclusion:
low hazard (no threshold derived)
Most sensitive endpoint:
repeated dose toxicity
DNEL related information

Local effects

Long term exposure
Hazard assessment conclusion:
hazard unknown (no further information necessary)

Workers - Hazard via dermal route

Systemic effects

Long term exposure
Hazard assessment conclusion:
DNEL (Derived No Effect Level)
Value:
4.2 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):
72
Modified dose descriptor starting point:
NOAEL
Value:
300 mg/kg bw/day
Explanation for the modification of the dose descriptor starting point:
An OECD 422 combined 28-day/reproduction screening study with AAI-TEPA resulted to an overall NOAEL of 300 mg/kg/day. Extrapolation from oral NOAEL represents a worst case situation, as dermal absorption is considered to be lower compared to oral absorption.
AF for dose response relationship:
1
Justification:
No specific concerns. Effects at LOAEL are not severe and probably only of local nature.
AF for differences in duration of exposure:
6
Justification:
The guidance indicates that for subacute to chronic a factor 6 should be applied. A lower factor could be considered as the females have been dosed for at least 43 days rather than 28 days.
AF for interspecies differences (allometric scaling):
4
Justification:
Default factor for allometric scaling from rat to human.
AF for other interspecies differences:
1
Justification:
ECETOC reported in 2010 after an extensive review that there is no justification for the suggested additional factor of 2.5 for this, therefore a factor of 1 has been applied. As effects are interpreted as being local related to the route of exposure, the applied allometric scaling already represents a worst case.
AF for intraspecies differences:
3
Justification:
ECETOC reported in 2010 after an extensive scientific review that the appropriate fact for intra-species differences for workers is 3 and not 5. As the effects for which the risk assessment is made is based on a local response following an non-specific mechanism with expected inherently relative low variation between individuals, no additional factor is needed to accommodate for possible high uncertainty between individuals on the basis of possible specific sensitivities.

AF for remaining uncertainties:

Workers - Hazard for the eyes

Local effects

Hazard assessment conclusion:
medium hazard (no threshold derived)

Additional information - workers

As explained in the category justification, for cross-reading in general use is made of data from substances of same or lower EA-length where available. For "Fatty acids C18 unsat, reaction product with polyethylene amines" (or AAI-PolyEA) cross-reading is applied to Fatty acids C18 unsat, reaction product with pentaethylenehexamine (AAI-PEHA).

Workers:

Inhalation route:

Use of the substance is limited to industrial and professional users. The likelihood of exposure via inhalation is low considering its high boiling point (> 300 °C) and very low vapour pressure (< 0.00017 mPa at 25°C) and use applications that do not involve the forming of aerosols, particles or droplets of an inhalable size.

 

Dermal route:

No threshold effect: Substance is corrosive and sensitising. Effects following dermal exposures will be characterized by local corrosive and possible sensitising effects that are related to duration, quantity and concentration of the substance, rather than by systemic toxicity due to dermal uptake. Specifically as acute oral toxicity is low.

For corrosive and sensitising substances, the use of protective gloves and other equipment, such as face shields, aprons and good work practices are mandatory. As a result, direct dermal contact occurs only occasionally. Therefore, repeated substantial daily dermal exposure is unlikely. (For properly labelled corrosives, the emphasis in the CSR and ES should be on the presentation of adequate risk management measures, rather than on the assessment of the risks from dermal exposure.)

Oral

DNEL derivation method:
ECHA REACH Guidance
Overall assessment factor (AF):
30
Modified dose descriptor starting point:
NOAEC
Value:
261 mg/m³
Explanation for the modification of the dose descriptor starting point:
An OECD 422 combined 28-day/reproduction screening study with AAI-TEPA resulted to an overall NOAEL of 300 mg/kg/day. The corrected 24 hr inhalation NOAEC for general population is NOAEL (30) * 1/1.15 mg/m3 = 261 mg/m3. No factor 2 route extrapolation from oral to inhalation. Due to very low vp (< 0.00017 mPa at 25°C), exposure is only possible as aerosol. 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.

Additional information - General Population

General population: These substances are only applied in professional or industrial setting in oilfield and mining applications applying adequate PPE. Use results to the inclusion into or onto a matrix. Consequently, consumers/general population will not be exposed.

However, in order to be able to evaluate possible secondary exposures via environment, additionally long-term systemic DNELs for general population have been derived.
