Description of key information

According to the results od a OECD TG 121 (Estimation of the Adsorption / Desorption Coefficient Koc), the Koc for the similar substance ursodeoxycholic acid is 48 and the logKoc value is 1.69.

Key value for chemical safety assessment

Koc at 20 °C:
48

Additional information

The Koc for the methyl 3-α,7-α-diacetoxy-12-oxo-5-β-cholan-24-oates, according to a read-across principle with ursodeoxycholic acid, is 48 and the logKoc value is 1.69.

Basing on these results, methyl 3-α,7-α-diacetoxy-12-oxo-5-β-cholan-24-oate is expected to have a high mobility in soil.
