Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The endpoint is waived based on the Kow and that it is expected to have a low potential for adsorption.

Key value for chemical safety assessment

Koc at 20 °C:
125.1

Additional information

The relevant regression equation within ECETOC TRA is the nonhydrophobics model: Log Koc = 0.52 Log Kow + 1.02.  The Log Kow (2.07) is within the domain (-2 to 8) (EC, 2003).  The chemical domain for the nonhydrophobic model is characterised as all chemicals that are not categorised as hydrophobics.  Alcohols are known to be overestimated and Amino PAHs, aliphatic amines and alkyl ureas are underestimated.  The substance lies within the nonhydrophobics model domain as defined by the Log Kow range, the absence of structural features mentioned above, and given that it is the preferred default model (ECHA, 2008a), it is considered valid for use.   The predicted Log Koc value of the test substance is 2.09 (Koc = 125.1 L/kg).
