Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

22 °C

Additional information

Biodegradation in the aerobic soil was rapid with an estimated half-life of 1.6 days. After an initial sharp decline, the test substance concentration gradually levelled off after 28 days at ≈3.5 – 6.2% of the total mass applied at day 0. This would be equal to 93.8- 96.5% primary degradation by day 28. Metabolite levels reached steady-state at 120 days.

The underlying hypothesis for the read-across is the test substance is transformed metabolically to 6:2 FTOH. Additional documentation, provided within IUCLID, supports the read-across approach.
