Endpoint summary
Administrative data
Description of key information
The substance was shown having an oral LD50 of > 2020 mg/kg bw to rats and a dermal LD50 of > 2000 mg/kg bw to rats. As the test substance has a very low vapor pressure and high melting point, the potential for the generation of inhalable forms is low, also the use of this substance will not result in aerosols, particles or droplets of an inhalable size. Hence, exposure to humans via the inhalatory route will be unlikely to occur, and no acute inhalation test was performed.

- 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 was found not being toxic via the oral route with a LD50 of >2020 mg/kg bw. The absence of two amines does not influence the oral toxicity 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:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 401 (Acute Oral Toxicity)
- Sex:
- male/female
- Dose descriptor:
- LD50
- Effect level:
- > 2 020 mg/kg bw
- Based on:
- test mat.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The source substance, being a suitable surrogate for assessing the scute oral toxicity of fatty acids, tall-oil, reaction product with maleic anhydride and triethylenetetramine was found havin an oral acute toxicity of > 2020 mg/kg bw in an OECD 401 guideline study.

Additional information
Justification for classification or non-classification
Based on data from acute oral and dermal toxicity studies to rats, both resulting in LD50 values above 2000 mg/kg bw, no classification for acute oral or dermal toxicity is required according to CLP (Regulation EC No 1272/2008). No signs of systemic toxicity were seen in the acute studies available and thus, also no classification for single exposure systemic target organ toxicity (STOT SE) is required.
