Description of key information

The solubility of the substance in water is very good and the solubility in octanol is poor. The octanol-water partitioning coefficient hence is anticipated to be very small. 

Key value for chemical safety assessment

Log Kow (Log Pow):
-4.2
at the temperature of:
22.4 °C

Additional information

Neither the HPLC method according to OECD Guideline No. 117 nor the flask-shaking method according to OECD Guideline No. 107 were applicable for the determination of the partition coefficient of FAT 40850/A TE.

Thus, the log Pow-value for the test item was estimated from its solubility in n-octanol and in water, respectively:

log Pow = log (8.9 [mg/L] / 128094.3 [mg/ L]) = -4.2.
