Description of key information

The log Koc of FC-770 was calculated to be 4.71 based on log Kow derived from experimental data.

Key value for chemical safety assessment

Koc at 20 °C:
51 300

Additional information

FC-770 is not released to the terrestrial compartment in its registered uses. The logarithm of the normalized organic carbon adsorption coefficient (log Koc) of FC-770 was calculated to be 4.71 based on the log Kow derived from experimental data. Due to lack of release to the terrestrial compartment, volatility, and extremely high Henry's law constant, we have proposed omission of further testing of sorption for FC-770 in the terrestrial compartment as providing no useful information.
