Considering the calculated Bioaccumulation Estimates (EPISUITE, v4.10) of the worst case BCF = 104.5 L/kg regression-based method, wet-wt , BCF = 0.8976 (Arnot-Gobas method, upper trophic), BAF = 0.8976 (Arnot-Gobas method, upper trophic) and the estimated Log Kow of 10.08 and the readily biodegradability, which makes exposure of the aquatic compartment unlikely, and no toxicity to fish (EC50 >100 mg/L), uptake into fish is expected to be hindered by the large molecular size (therefore a strong steric hindance for crossing biological membranes is indicated), no bioaccumulation is expected. If taken up by fish, these carboxylate ester-containing substances are expected to be readily metabolized and excreted. Sedimental and terrestrial bioaccumulation is considered to be not relevant as the substance is readily biodegradable.

In addition, based on current knowledge, a calculated log Kow of 10 or above is taken as an indicator of reduced bioconcentration. (Chapter R.7C-Endpoint Specific Guidance; R7.10.3.4)

Based on all relevant data available for the assessment of the bioaccumulation potential, it can be concluded that Soybean oil, epoxidized, reaction products with methanol has low potential for bioaccumulation and biomagnification via the food chain.
