Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

71% within 28 days (at a concentration of 10.3 mg/L) but the 10-day window was not reached
7% wihtin 28 days (at a concentration of 20.2 mg/L)

Key value for chemical safety assessment

Additional information

The biodegradability of the substance was tested for 28 days at concentrations of 10.3 and 20.2 mg/L (with the use of Tween 80).

The test substance was found to be readily biodegradable when tested at a concentration of 10.3 mg/L (71% wihtin 28 days) but the pass value was not reached in a 10 -day window. At a concentration of 20.2 mg/L, the substance is not biodegradable (7% within 28 days ).

Due to the poor solubility in water the speed of solubilization is likely to be the limiting factor for the rate of biodegradation
