Conclusion on classification
Environmental classification justification
Aquatic compartment
Official classification
In accordance with Regulation (EC) No 1272/2008, Annex VI Table 3.1 or Table 3.2, the substance is officially not classified.
Self classification
Following DSD/DPD, the substance is not to be classifed as dangerous for the environment. Although the lowest LC/EC50 value is 48.5 mg/L, the substance is readily biodegradable. Moreover, the log Pow is < 3 (no experimentally determined BCF).
Following CLP (GHS-EU), the substance is not to be classified as acutely hazardous to the aquatic environment since the lowest LC/EC50 is > 1 mg/L.
Chronic data are available for all three trophic levels (fish, Daphnia, algae). The available NOECs are greater than 1 mg/L, therefore the substance is not to be classified as chronically hazardous to the aquatic environment.
Atmospheric compartment
The test substance is not listed 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.
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.
