Description of key information

Surface tension 62.4 mN/m at 21.8 ± 0.5 °C (OECD 115)

Key value for chemical safety assessment

Surface tension:

Additional information

The surface tension of a 90% saturated solution (1.50 x 10-2 to 2.09 x 10-2 g/L) of Patchouli Oil in water was 62.4 mN/m at 21.8 ± 0.5 °C. The test item was therefore considered not to be surface-active.
