Description of key information

The octanol-water partition coefficient has been determined according to OECD Guidelines for the Testing of Chemicals, 'Partition coefficient (l-octanol/water): Slow stirring method', no 123.

The Log Kow has been determined at two test conditions, at pH 7 and at reduced pH (3-4) as the substance is a tertiary amine with a calculated pKa of 5.7 (SPARC). At pH 7 a log Kow of 6.2 was observed where at pH 3-4 a log Kow of 3.7 was observed.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25.3 °C

Additional information

The log Kow has been determined for this substance as it is a required endpoint for the registrations dossier but because the substance evaluated is a surface active substance, it is not clear if this log Kow has any meaning for predicting the bioaccumulation potential or sorption potential of this substance.
