Description of key information

An adsorption/desorption study was not conducted due to LogKow < 3 and ready biodegradability of the test item.

Koc was calculated with EUSES Version 2.1.2. Koc: 185

Key value for chemical safety assessment

Koc at 20 °C:
185

Additional information

Koc was calculated with EUSES 2.1.2 using the following parameters:

Molecular weight: 623 g/mol (molecular weight of main constituent based on oleic acid as major fatty acid moiety for the acidic form with the

representative molecular formula of C 30 H 54 O 13)

Melting point: 150 °C

Vapour pressure: minimum (1E-06)

Water solubility: 0.2 g/L (according to critical micelle concentration (CMC))

LogKow: 2.4, worst case value calculated from measurement of CMC and solubility in octanol

Chemical class: default QSAR
