Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint summary
Administrative data
Description of key information
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- adverse effect observed (sensitising)
- Additional information:
Tall oil fatty acids, reaction products with polyethylenepolyamines (Amidoamine) was found to be sensitising to skin in a GPMT test.
All substances within the AAI group show the same reactive groups, show similar composition of amide, imidazoline, and some dimer structures of both, with the length of original EA amines used for production as biggest difference. Inherent reactivity and toxicity is not expected to differ much between these substances, aspects which determine sensitization.
All skin sensitisation studies performed on AAI substances all indicate them to be sensitising.The following information is available on sensitising properties of AAI substances:
TO + DETA Sensitising: 40% positive reaction in GPMT
TO + DETA Sensitising: LLNA: EC3: 0.3%.
C16-18, C18 unsat + TEPA Sensitising: 100% positive reaction in GPMT
TO + PolyEA(Amidoamine) Sensitising: 100% positive reaction in GPMT
Based on the available data, all substances in the AAI group should be considered sensitising to skin.

Respiratory sensitisation
Endpoint conclusion
- Additional information:
There is no information on respiratory sensitisation, but AAI products are sensitising to skin.
The likelihood for exposure via inhalation and thus becoming sensitised to AAI, is however very low, based on the high boiling point (> 300 °C) and very low vapour pressure (0.00017 mPa at 25°C for DETA based AAI).
Migrated from Short description of key information:
No data.
Justification for classification or non-classification
Tall oil fatty acids, reaction products with polyethylenepolyamines (Amidoamine)was found to be sensitising to skin in a GPMT test.
The actual risk of sensitisation is probably low, as AAI are corrosive to skin and consequently exposure will be low due to necessary protetive measures to limit dermal exposure.
Also the likelihood for exposure via inhalation and thus becoming sensitised to AAI, is very low, based on the high boiling point (> 300 °C) and very low vapour pressure (0.00017 mPa at 25°C for DETA based AAI).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
