Description of key information

The substance is considered as not bioaccumulative. It is proposed to use a BCF of 861 L/kg in the chemical safety assessment as this was the maximum predicted BCF.

Key value for chemical safety assessment

BCF (aquatic species):
861 L/kg ww

Additional information

The bioconcentration factor of the substance allyl heptanoate was calculated with the BCFBAF program (as of September 2010, described in Meylan et al. 1999) using a fragment based QSAR model and with a QSAR model built on the relationship between the log Kow and BCF (Veith et al. 1979). The BCFs calculated with the models were 307.8 L/kg and 861 L/kg. Both values are below the cut-off value of 2000 L/kg triggering classification of substances as bioaccumulative. It is concluded that the B criterion is not met for allyl 3-cyclohexylpropionate and the substance is considered as not bioaccumulative.
