Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1: no data found

According to Regulation (EC) 1272/2008 Annex VI Table 3.2: no data found

 

Self-classification

Aquatic compartment

Following DSD/DPD, the substance is not to be classified as dangerous for the aquatic environment.

Rationale: The lowest acute toxicity to aquatic organisms (LC/EC50) is between 10 and 100 mg/L, the substance is readily biodegradable and the log Pow is < 3.

 

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 also not to be classified as chronically hazardous to the aquatic environment.

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 Daphnia and algae. Therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: Chronic data are available for Daphnia (NOEC = 7.2 mg/L) and algae (NOErC = 50 mg/L). The substance is rapidly degradable and the lowest NOEC is > 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 not to be classified.

- Acute toxicity data: Fish is the trophic levels not covered by chronic data. Therefore classification is based on the respective acute effect data.

The LC50 is >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.

 

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.
