Description of key information

The log Kow of the constituents of Lemon Oil is above 4.0 for  91% of the composition. With log Kow 4.83 (predicted) or 4.38 (measured), limonene represents the group with a high log Kow.  

Key value for chemical safety assessment

Additional information

The predicted log Kow of the constituents of Lemon Oil (typical composition) ranges from 3.33 -6.3. Log Kow is above 4.0 for 91% of the typical constituent composition, whereas the lowest (3.33) and highest (6.3) values were for constituents comprising both 1% of the NCS. For limonene the log Kow was 4.83 (predicted) or 4.38 (measured, Griffin et al, 1999).
