Description of key information

The bioconcentration factor (BCF) was estimated using a QSAR program (EPIWIN BCFBAF Program, V3.00).  The Arnot/Gobas method was used, which assumes an upper trophic level fish of 10 g.

Key value for chemical safety assessment

BCF (aquatic species):
2.383 L/kg ww

Additional information

Based on an estimated bioconcentration factor (BCF) of 2.383, benzoic acid, 2-hydroxy-, 2-butyloctyl ester is not expected to bioaccumulate.
