Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 (fish: 96-h LC50 >500 mg/L; daphnids: 48-h EC50 >500 mg/L; algae: 72-h EC50 > 500 mg/L).


 


Experimentally determined chronic data are available only for algae; however, estiamted data also yielded effect values for fish and aquatic invertebrates. The classification is based on the available chronic and acute toxicity data.


 


- Chronic toxicity data:


The availabel chronic NOECs are greater than 1 mg/L (algae: 72-h NOErC ≥ 500 mg/L; aquatic invertebrates:21-d NOEC 56.8 mg/L; fish: NOEC > 5 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:


Fish and invertebrates are the trophic levels not covered by experimentally derived chronic data. Therefore, the assessment is based on the respective available acute toxicity data (fish: 96-h LC50 >500 mg/L; daphnids: 48-h EC50 >500 mg/L). The substance is rapidly biodegradable (freshwater); the Log Kow is < 4 (-0,77 at 25°C). According to the criteria outlined in Table 4.1.0(b) (iii) (Commission Regulation (EU) No 286/2011 amending Regulation (EC) No 1272/2008) the substance is not to be classified as chronically hazardous to the aquatic environment.


 


- Conclusion: The substance is not to be classified as chronically hazardous to the aquatic environment.
