Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

According to Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2, the substance is not classified regarding environmental hazards. 

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 between10 and 100 mg/L in freshwater (Daphnia magna, 48 -h EC50: 22 mg/L).

- The substance is readily biodegradable (freshwater) 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 acute and chronic data, the substance is 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 algae, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available only for algae (72h ErC10 = 156 mg/L) indicating that the substance does not present a long-term hazard according to the categories outlined in Table 4.1.0(b) (ii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) for rapidly degradable substances.

- Acute toxicity data:

Acute toxicity to aquatic organisms (LC/EC50) is between 10 and 100 mg/L in freshwater (48h EC50 Daphnia: 22 mg/L).

The substance is rapidly biodegradable and has a log Kow <4.

The result of the marine biodegradation studies according to OECD 306 may be considered in case of uses in the marine 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.
