Description of key information

Estimation of the Adsorption Coefficient (KOC) of FAT 40858/A TE using High Performance Liquid Chromatography (HPLC)

Key value for chemical safety assessment

Additional information

The adsorption coefficient of the test item was to be determined from its retention time on a cyanopropyl phase in comparison with recommended reference items. No retention was found for the test item.

Therefore the logarithmic adsorption coefficient log KOCof the test item was estimated to be below 1.25 (lowest available reference value) using the HPLC screening method.
