Description of key information
Additional information
Category Amidoamines/imidazolines (AAI):
Amidoamine/imidazolines are reaction products of fatty acid and polyethyleneamines.
The resulting product therefore is a mixture of the amide structure of the fatty acid and the polyethyleneamine and its imidazoline. Also is possible that two fatty acid molecules bind at each end of the polyethyleneamine resulting to di-substituted amine or imidazoline. The final product is a mixture of these substances, containing amine-, amide-, and Imidazoline functional groups.
Furthermore it has been demonstrated that the imidazoline bond is readily hydrolysed, to re-form the Amidoamine form.
The members of this category can be characterised by their starting materials: the hydrophobic part from fatty acids and the hydrophilic part from the polyethyleneamines:
- Fatty acids (FA):
The difference in alkyl chain length distribution is limited among the members of this category. The majority is C18 unsaturated alkyl.
- Polyethyleneamines (EA):
The chain length of the polyethyleneamines used for the production of the various Amidoamines/imidazolines in this category can vary. In order of increasing EA length ranging from DETA (diethylenetriamine), TETA (triethylenetetramine), TEPA (tetraethylenepentamine), PEHA (pentaethylenehexamine) and higher, generally denoted as polyethyleneamines (PolyEA). Although some products are derived from the use of basically one specific ethyleneamine, often a mixture of ethyleneamines of different lengths are used.
All substances within the AAI group show the same reactive groups, show similar composition with the length of original EA amines used for production as biggest difference.
Justification for read-across of Phys-Chem properties
Due to the chemical similarity of the substances in the category, it is considered that the main factor influencing physical-chemical properties is the molecular weight of the substance. It is considered that C18 unsaturated fatty acid reactions product with diethylenetriamine as the smallest molecule represents the highest volatility and the lowest boiling point, flash point and self-ignition temperature.
It is also expected that as the hydrophilic polyethylene chain increases the partitioning coefficient will decrease, or be of same magnitude. Viscosity is expected to increase with the molecular weight.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
