Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The aquatic toxicity of the test item DV6850 was tested in short-term toxicity tests to fish, daphnia and algae. The tests were conducted under GLP. Fish was the most sensitive organism with a LC50 of 0.406 mg/L, followed by daphnia with an EC50 of 33.6 mg/L. For algae, ErC50 and EbC50 of 85.4 mg/L and 57.6 mg/L were observed, respectively. The results indicate that the test item is acute toxic to aquatic organisms. Further, the effect of DV6850 on the respiration rate of activated sludge was assessed in a valid GLP study. DV6850 was considered to have had no effect on the respiration rate of activated sludge at any of the concentrations employed in the test. The EC50 of the test substance could not, therefore, be calculated but it must be greater than 100 mg/L, the highest level tested.

No information on sediment toxicity and terrestrial toxicity is available.

Conclusion on classification

The substance has to be classified as "hazardous to the aquatic environment", Category Acute 1 and Category Chronic 1, according to Commission Regulation (EU) No 286/2011 of 10 March 2011 (second amendment of CLP regulation), as the 96 hour LC50 for fish is lower than 1 mg/L and there is evidence that the log Kow of the substance is greater than 4.
