Description of key information

The substance is expected to have a low potential for bioaccumulation.

Additional information

The target substance 2-octyldodecyl 12-[(1-oxooctadecyl)oxy]octadecanoate (CAS 90052-75-8) is a long-chain aliphatic ester with a high estimated log Kow, which suggests a potential for bioaccumulation. However, since the substance has low water solubility and is readily biodegradable, no chronic exposure and relevant uptake is likely. In the case of uptake by fish, the substance is expected to be rapidly metabolized via enzymatic hydrolysis into its corresponding fatty acids and fatty alcohols. From literature it is well known that these hydrolysis products will be effectively metabolized and excreted by fish (Heymann, 1980; Lech & Bend, 1980; Lech & Melancon, 1980; Murphy & Lutenske, 1990; Sand et al., 1973).

In conclusion, the substance is expected to have a low potential for bioaccumulation.
