Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusion on classification

Official classification regarding environmental hazards

Aquatic compartment

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.1, the substance is not officially classified.

In accordance with Regulation (EC) 1272/2008 Annex VI Table 3.2, the substance is not officially classified.

 

Self-classification

Aquatic compartment

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 from experimental read-across data; therefore classification is based on the available chronic and acute toxicity data:

- Chronic toxicity data:

Chronic data are available only for algae from experimental read-across data (lowest chronic value: read-across data for CAS 100-74-3). The 72-h ErC10 was determined to be 131.7 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 >100 mg/L in freshwater [96h LC50 for fish: >500 mg/L; 48h EC50 Daphnia: >100 mg/L (read-across data from CAS 109-02-4); 72h EC50 for algae: 580 mg/L (read-across data from 100-74-3)].

 

The substance is not rapidly biodegradable (according to OECD criteria); the log Kow is <4.

 

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.
