Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In accordance with column 2 of REACH Annexes VIII and IX, the adsorption / desorption studies (required in sections 9.3.1 and 9.3.3) do not need to be conducted as the substance is expected to have a low potential for adsorption since it has a low octanol water partition coefficient (log Kow  < 3)  and is readily biodegradable.

A supporting QSAR reported a log Koc value of 0.5413 and a Koc value of 3.478 L/kg for the substance, estimated from Kow.

Key value for chemical safety assessment

Koc at 20 °C:
3.478

Additional information

The adsorption coefficient (log Koc) was estimated by two QSAR models:

- KOCWIN v2.00 in EPI suite (v4.0) - MCI method using log Kow

- KOCWIN v2.00 in EPI suite (v4.0) - log Kow method

The value calculated from Kow is more conservative therefore it has been selected for chemical safety assessment.
