Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There is no data in Regulation (EC) 1272/2008 Annex VI Table 3.1 and 3.2 for the substance available yet.

 

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 greater than 1 mg/L in freshwater (lowest value: algae 1.08 mg/L; there is no real EC50 value available. Therefore the calculated EC0 out of four read-across substances was used as worst case scenario).

- 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 for algae and invertebrates, therefore classification is based on the available chronic and acute toxicity data.

- Chronic toxicity data:

Chronic data are available only for algae (calculated 72h ErC0 = 1.08 mg/L; read-across approach with calculated EC0 as worst case scenario) and invertebrates (7d NOEC = 1.5 mg/L; read-across from Ceriodaphnia dubia with butylamine) 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 (48h EC50 Daphnia: > 100 mg/L, 96h LC50 fish: > 500 mg/L).

The substance is rapidly biodegradable (freshwater) and the log Kow is <4.
