Additional information
Conclusion on classification
Tridecylamine, branched and linear (CAS 86089 -17 -0) is a mixture of alkylamines of C13 isomers (99.8 -100%). For this fraction1-tridecanamine (CAS 2869-34-3) was selected as representative C13 substance. This isomer is a linear molecular with the largest chain length within the mixture. As toxicity increases with the chain length toxicity data can be regarded as a worst-case approach. The assessment of ecotoxicology is predominantly focused on this molecule.
Official classification regarding environmental hazards
Aquatic compartment
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not officially classified.
In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not officially classified.
Self-classification
Aquatic compartment
Acute (short-term) aquatic hazard
Following CLP, the substance is to be classified as acutely hazardous to the aquatic environment (Category Acute 1).
Rationale:
The substance is to be classified as acutely hazardous to the aquatic environment, since all the lowest acute effect value of the three trophic levels is <= 1 mg/L (E(r)C50 = 0.015 mg/L; ((48-h) daphnia: read-across to CAS 2869-34-0, Pedersen et al., 1998; algae: (76-h) BASF AG, 1988-1989; Rep no.: 2/1034/(2)/88(89)).
Long-term aquatic hazard
Following CLP, the substance is to be classified as chronically hazardous to the aquatic environment (Category Chronic 1).
Rationale:
Chronic data are available only for algae. Therefore, classification is based on the available chronic and acute toxicity data.
- Chronic toxicity data: The substance is not rapidly degradable and the ErC10 is <= 0.1 mg/L (algae, ErC10 = 0.0032 mg/L). According to the criteria outlined in Table 4.1.0(b) (i) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is to be classified as chronically hazardous to the aquatic environment (Category Chronic 1).
- Acute toxicity data: Fish and aquatic invertebrates are the trophic levels which are not covered by chronic data. Therefore, classification is based on the respective acute effect data. The lowest EC50 was determined for aquatic invertebrates (EC50 = 0.015 mg/L), the substance is not rapidly degradable and the log Pow is > 4. According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is to be classified as chronically hazardous to the aquatic environment (Category Chronic 1).
- Conclusion: The substance is to be classified as chronically hazardous to the aquatic environment.
Based on Table 4.1.3, the lowest acute toxicity value (E(r)C50 = 0.015 mg/L) is within the range of 0.01 to 0.1 mg/L; therefore, the M-factor is 10 for acute toxicity. The lowest chronic value (EC10 = 0.0032 mg/L) is within the range of 0.001 and 0.01 mg/L; therefore, the M-factor is 10 for chronic toxicity as well.
