Conclusion on classification
Environmental classification justification
Harmonised classification regarding environmental hazards
Aquatic compartment
For n-butylamine, a harmonised classification is available in Regulation (EC) 1272/2008 (CLP) Annex VI. The substance is not classified for environmental hazards.
Self-classification according to REGULATION (EC) No. 1272/2008 (CLP)
Aquatic compartment
According to REGULATION (EC) No. 1272/2008 (CLP), the substance is not to be classified as acutely hazardous to the aquatic environment since the lowest LC/EC50 is > 1 mg/L. The substance is also not to be classified as chronically hazardous as it is rapidly degradable and the available effect values for chronic effects on daphnids and algae are > 1 mg/L.
Atmospheric compartment
The test substance is not listed in Annex 1 of Regulation (EC) 2037/2000 on substances that deplete the ozone layer.
The test substance does not belong to the green house gases listed in P Forster, PV Pamaswamy et al. Changes in Atmospheric Constituents and Radiative Forcing. In: Climate Change 2007: The Physical Basis. Contribution of Working Goup 1 to the Fourthe Assessment Report of the Intergovernmental Panel on climate Change.
Self-classification according to UN-GHS ST/SG/AC.10/30 /Rev.7 (2017)
Because of E(L)C50-Values between 1 and 10 mg/L (Aquatic invertebrates EC50 (48 h) = 8.2 mg/L), the following acute toxicity classification applies:
o Aquatic Acute 2
o H401: Toxic to aquatic life.
For chronic aquatic toxicity, no classification is applicable (see EU-GHS (CLP) above for details).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
