- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
The target substance Fatty acids, tall-oil, reaction products with maleic anhydride and triethylene-tetramine (TOFA-MA-TETA) and the source substance Fatty acids, tall-oil, reaction products with di-ethylenetriamine (DETA), maleic anhydride, tetraethylenepentamine (TEPA) and triethylenetetramine (TETA) are characterised by the same starting materials: the hydrophobic part from fatty acids and the hydrophilic part from the polyethyleneamines.
The source substance is a mixture of ethyleneamines of different lengths (DETA, TETA and TEPA). The target substance contains only one ethyleneamine: TETA.
The source and the target substance show therefore the same reactive groups and a similar composition with the absence of two original ethyleneamines (DETA and TEPA) as biggest difference. A read-across to the source is therefore justified.
2. SOURCE AND TARGET CHEMICAL(S) (INCLUDING INFORMATION ON PURITY AND IMPURITIES)
The target substance actually is manufactured from the same starting materials of the source:
Fatty acids, tall-oil and maleic anhydride. TOFA is reacted with maleic anhydride to make a Diels-Alder intermediate which is a tri-acid. This is reacted with the TETA to produce a mixture of amido-amine & oligomeric UVCB constituents. The source substance also contains two other ethyleneamines: di-ethylenetriamine and tetraethylenepentamine.
The source substance has been registered already and the NOEC, LOEC and IC50 values after 24 and 48 h, calculated based on nominal concentration tested, were as follows:
NOEC 100 mg/L
LOEC > 100 mg/L
IC50 > 100 mg/L.
The absence of two amines does not influence the acute toxicity effect on aquatic invertebrates of the substance.
3. ANALOGUE APPROACH JUSTIFICATION
The target substance is one of the constituent of the UVCB source substance and thus read-across from the bigger compound Fatty acids, tall-oil, reaction products with diethylenetriamine, maleic anhydride, tetraethylenepentamine and triethylenetetramine to TOFA-MA-TETA is common practice and justified.
4. DATA MATRIX
Whereas the source substance is a Fatty acids, tall-oil, reaction products with di-ethylenetriamine (DETA), maleic anhydride, tetraethylenepentamine (TEPA) and triethylenetetramine (TETA), hence using a mixture of DETA, TETA and TEPA as reactant, the target substance uses pure TETA (triethylenetetramine) instead, being a more purified (narrower cut distillation) form of DETA/TETA/TEPA resulting in a name change of the target substance, being Fatty acids, tall-oil, reaction products with maleic anhydride and triethylenetetramine (TETA). - Reason / purpose for cross-reference:

- Conclusions:
- The test item “Fatty acid, tall-oil, reaction products with diethylenetriamine, maleic anhydride, tetraethylenepentamine and triethylentetramine” caused no adverse effect to Daphnia magna after 48-hours exposure at a nominal product concentration of 100 mg/L under static conditions.
The NOEC, LOEC and IC50 values after 24 and 48 h, calculated based on nominal concentration tested, were as follows:
NOEC 100 mg/L
LOEC > 100 mg/L
IC50 > 100 mg/L.
