Key value for chemical safety assessment
Additional information
No experimental studies investigating the bioaccumulation potential of isodecyl pivalate (CAS 60209-82-7) are available. Therefore, the bioaccumulation factor (BCF) of the substance was estimated using a reliable QSAR model (BCFBAF v3.01). The substance is in the applicability domain of the model indicating that the results are reliable and can be used to assess the bioaccumulation potential of isodecyl pivalate. The BCF was calculated to be 202 L/kg using the regression-based model and 241.5 L/kg resulting from the Arnot-Gobas model which includes biotransformation. An exclusion of biotransformation resulted in a clearly higher BCF of 21000 L/kg. The substance is expected to be extensively metabolized (half-life: 0.71 d corresponding to approx. 17 h) which reduces the bioaccumulation potential significantly in a short period of time. Rapid biotransformation and extended metabolism of the hydrolysis products is also indicated based on mammalian data. For a detailed review on metabolism of the substance, please refer to the toxicokinetics statement in IUCLID Section 7.1. In conclusion, isodecyl pivalate has a low potential for bioaccumulation and the highest calculated BCF of 202 - 241.5 L/kg is clearly below the trigger value of 2000 L/kg for a substance to be considered as bioaccumulative (B-criterion) in the PBT assessment.
