Description of key information

The water solubility is < 0.05 mg/L at 20 °C with a pH of approximately 6.2 (EU A.6.)

Key value for chemical safety assessment

Additional information

The key value for the water solubility is taken from the study report of one of the main constituents, C16 palmitic acid, for which the test was performed in accordance with EU method A.6 and results in a water solubility below 0.05 mg/L at 20 °C.

An experimental value for Fatty acids, C16 -22 was available, however, it was less precise (< 50 mg/L).
