Description of key information
The substance is considered as not bioaccumulative. It is proposed to use a BCF of 2000 L/kg in the chemical safety assessment as proposed in ECHA guidance R.7c.
Key value for chemical safety assessment
- BCF (aquatic species):
- 2 000 L/kg ww
Additional information
The bioconcentration factor of the substance 3,5,5-trimethylhexyl acetate 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 503.6 L/kg and 1622 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 3,5,5-trimethylhexyl acetate and the substance is considered as not bioaccumulative.
