Description of key information
The Partition coefficient of Eucalyptus oil was derived from data on its major constituents.
The substance has potential to bioaccumulate in the environment, according to CLP classification criteria for aquatic chronic toxicity (log Kow >4).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 4.42
Additional information
Eucalyptus oil is a natural complex substance. It is a mixture of several component, but three of them represent 90% of that mixture. Log Kow of each of these three components were calculated
with the In Silico Algorythm For Environmental Risk assessment Toolbox, Multilinear v.1.1 (i-SAFERAT Toolbox, Multilinear v.1.1) and the results are below:
- 1,8 -cineol, logP = 2.84
- (d,l)-limonene, logP = 4.35
- alpha-pinene, logP = 4.42
Regarding the relative wide range values of logP for these components, it is not assumed to perform a geometric mean to these values. Therefore, for the risk assessment, log Kow values will be determined using the lowest (2.84) and the highest (4.42) logP values, and for the BCF, only the highest value (4.42) will be used.
Regarding that range, Eucalyptus oil can be excluded as potential Bioaccumulative in a PBT context.
