Conclusion on classification
Hexylamine
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
Following DSD/DPD, the substance is not to be classified as dangerous for the environment.
Rationale: the acute toxicity to aquatic organisms (LC/EC50) is > 1 mg/L, the substance is readily biodegradable, the measured log Kow is < 3 and the calculated BCF is <100.
Following GHS, the substance is not to be classified as acutely hazardous to the aquatic environment. Based on the available chronic data, the substance is to be classified as chronically hazardous to the aquatic environment (Chronic 3).
Rationale:
The substance is not to be classified as acutely hazardous to the aquatic environment, since the lowest acute effect value is > 1 mg/L.
Chronic data are available only for algae. Therefore classification is based on the available chronic and acute toxicity data.
- Chronic toxicity data: Chronic data are available for algae (EC10 = 0.5 mg/L). The substance is rapidly degradable and the EC10 is > 0.1 and <= 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is to be classified as Chronic 3.
- Acute toxicity data: Fish and invertebrates are the trophic levels not covered by chronic data. Therefore classification is based on the respective acute effect data.
The EC50 for D. magna is > 1 and <= 10 mg/L and the LC50 for fish is >10 and <=100 mg/L, the substance is rapidly degradable and the log Pow is < 4. Therefore the substance is not to be classified as chronically hazardous based on acute toxicity data.
Hexylamine, crude
Self-classification
Hexylamine, crude is to be classified as chronically hazardous to the aquatic environment (Chronic 3) taking into account the composition of hexylamine, crude (chapter 1.2 composition) and the classification of the components:
- Hexylamine (CAS-# 111-26-2): classification: chronic 3
- Dihexylamine (CAS-# 143-16-8): classification: acute 1
- Trihexylamine (CAS-# 102-86-3): classification: chronic 2
- 1-Hexanol (CAS-# 111-27-3): classification: no classification
Atmospheric compartment
The test substance is not in Annex I of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.
The test substance does not belong to the greenhouse gases listed in P Forster, PV Ramaswamy et al. Changes in Atmospheric Constituents and in Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on climate Change.
