Hydrolytic stability was carried out using a procedure designed to be compatible with Method C7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004.

It has been observed that the rate of hydrolysis increases with an increase in pH. The substance was found to be hydrolytically stable at pH 4 and 7 and at pH 9 the rate constant was 3.61 X 10-8at 25 °C with an estimated half life of 222 days.

In the light of percentage degradation observed in water in screening tests the test item FAT 40061 is considered not to be readily biodegradable.

FAT 40061 has a low octanol water partition coefficient, therefore no adsorption/desorption study was conducted. For risk assessment purposes, the log Koc value was estimated from the log Kow value using KOCWIN v2.00. Log Koc value was estimated to be 0.05

This value indicates a mobile character of the test substance.
