Description of key information

The partition coefficient of the test substance was calculated using the ratio of individual solubilities in n-octanol and water (i.e., based on critical micelle concentration (CMC)), a method which is recommended for surface active substances according to OECD Guideline 107 (KLKL Kolb, 2020). 

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

(based on ratio of n-octanol solubility and critical micelle concentration)

The partition coefficient (log Kow) value of another test sample containing majorly C12 -14 chains was determined to 2.37 at 20 °C. The log Kow value of the more representative test sample has been considered for the risk assessment.
