Description of key information

The  mean lipid normalized steady state BCF(ssl) value <= 39 L/kg and lipid-corrected BMF value <= 0.016 with growth corrected whole body half-live < 0.6 days as estimated from the BCF and BMF of the source studies on Isodecanol and Isotridecanol.

Additional information

The registered substance, Alcohols, C9-11-branched (Isoundecanol), and the tested substances, Isodecanol and Isotridecanol, are part of a closely related group of products with structural similarity, made by the same manufacturing process. (Further detail is provided in assessment report for read-across.) Their structural and physicochemical properties follow an expected trend with C-chain length. The tested substances bracket Isoundecanol with respect to hydrophobicity and log Kow. As bioaccumulation is positively correlated with hydrophobicity, the BCF and BMF for Isoundecanol can be expected fall within the range listed above. Both the aqueous and dietary bioaccumulation studies indicate that these substances exhibit a low potential to bioaccumulate.
