Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Conclusion on classification

Conclusion on classification

Relevant parameters

Based on test data, the substance is readily biodegradable and shows no potential for bioaccumulation.

Biodegradation: readily biodegradable based on % BOD removal of 90% within 28 days and 62% biodegradation within 10 days.

Bioaccumulation: log Pow = 1.6 at 25°C

Toxicity to microorganisms:

Sludge, 3 h- EC50 > 1000 mg/L.

Aquatic acute toxicity

Three acute studies with freshwater specie were available.

Algae, 72 h- ErC50 > 100 mg/L

Daphnia, 48 h- EC50 > 100 mg/L

Fish, 96 h- LC50 = 73.8 mg/L

Aquatic chronic toxicity

Except for the algae test, no chronic test data are available.

Algae, 72 h- NOEC >= 100 mg/L

Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are only available for algae. The test substance is considered to be readily biodegradable and has a low potential for bioaccumulation (log Kow < 4.5). Fish was found to be the most sensitive species with a LC50 (96 h) of 73.8 mg/L. Following Regulation (EC) 1272/2008, the substance is not classified as acutely as well as chronically hazardous to the aquatic environment.
