Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not classified as hazardous to the environment.

According to Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not classified as hazardous to the environment.

 

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 1 and ≤ 10 mg/L.

- The substance is readily biodegradable.

- The log Kow is ≥3, but the BCF is <100.

 

Following GHS, the substance is not to be classified as acutely or 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 greater than 1 mg/L.

Chronic data are available only for algae (EC10 = 1.91 mg/L). Therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is rapidly degradable and the ErC10 is greater than 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) for rapidly degradable substances, the substance is not to be classified as chronically hazardous to the aquatic environment.

- Acute toxicity data: Fish is the trophic level not covered by chronic data. Therefore classification is based on the respective acute effect data. The lowest LC/EC50 is between 1 and ≤ 10 mg/L (Algae EC50 = 4.5 mg/L). The substance is rapidly degradable and the log Pow is < 4. The substance is not to be classified as chronically hazardous to the aquatic environment.

  

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.
