Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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 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 values available (algae: 72 -h ErC50 = 34 mg/L; read-across data from CAS# 104-78-9) are greater than 1 mg/L.

 

Chronic data are available for algae (72-h ErC10 = 26 mg/L) and aquatic invertebrates (22-d NOEC = 3.64 mg/L). Therefore, classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data: The substance is rapidly degradable and the lowest chronic value available (daphnids: 22-d NOEC = 3.64 mg/L) is greater than 1 mg/L. According to the criteria outlined in Table 4.1.0(b) (i) (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 96-h LC/EC50 for fish is 122 mg/L. The substance is rapidly degradable and the log Pow is < 4. 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.
