Description of key information

Additional information

Eucalyptus oil is a natural complex substance (NCS). It is a mixture of several components.

All major constituents of Eucalyptus oil are readily biodegradable. Therefore, Eucalyptus oil can be considered as a readily biodegradable mixture.

The bioaccumulation factor value (BCF) for Eucalyptus oil was determined regarding the highest log Kow value of the components. The highest log Kow value is for alpha-pinene (log Kow at 4.42), therefore it was assumed that BCF of alpha-pinene would be conservative enough for the mixture, which is 852.9 L/kg wet-wt (geometric mean between three calculation approaches).

For the adsorption potential of Eucalyptus oil, it’s not possible to determine only one adsorption coefficient (Koc) value to characterize the NCS based on the wide range of Koc values for the constituents. Therefore it is assumed that the lower and the greater Koc values should be considered for the Risk Assessment: Koc at 260.4 for 1,8-Cineol (log Koc = 2.44) and Koc at 3222.3 for alpha-pinene (log Koc = 3.49) (geometric mean between three calculation approaches).
