Additional information

A guideline-conform ready biodegradability study showed that allyl hexanoate is readily biodegradable. Furthermore the results of the hydrolysis study show that abiotic hydrolysis may contribute to the degradation of the substance in the environment, but that the rate of abiotic degradation is significantly depending on the environmental conditions. Based on the ready biodegradability, the substance can be considered as not persistent in the environment. It fulfils the "not (v)P" criterion for vPvB and PBT assessment and can be considered as rapidly degradable for classification and labelling purposes.

A log Koc value of 2.68 (QSPR estimation) indicates that the substance has a medium mobility in soil and sediments according to the classification scheme of McCall et al. (1981). Furthermore, it is assumed that the substance has a moderate volatility from water surfaces under environmental conditions due to its Henry’s Law constant of 94.7 Pa · m3/mol (at 25°C).

The calculated BCFs (using BCFBAF) of the substance are 59.2 L/kg and 102.3 L/kg, respectively. The B criterion is not fulfilled for the substance and thus, the substance is considered to be not bioaccumulative.
