pH 7 - 40.0 ± 0.5 °C Tier 2 Testing
Assessment of hydrolytic stability was carried out using a procedure
designed to be compatible with Method C.7 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.
The test substance was evaluated at pH 4 for 24h, 120 h, 144 h, 408 h,
552h and 744 h. For pH 7 and 9 the duration was 24h, 120 h and 144h. All
tests were carried out at 50 °C. The concentration used was 0.01 g/L.
Based on the findings of the study,
The rate constant and estimated half-life at 25 °C of the test item are:
At pH 4 the rate constant was 1.46 x 10-4 h-1 at 25 °C
The estimated half life at pH 4 at 25 °C was 198 days.
The estimated half life at pH 7 at 25 °C was >1 year.
The estimated half life at pH 9 at 25 °C was >1 year.
FAT 40032/G was determined to be hydrolytically stable.
A key assessment of hydrolytic stability was carried out using a
procedure designed to be compatible with EU Method C.7 and OECD
Guideline 111. Based on the findings of the study, the test substance
(FAT 40032/G) was determined to be hydrolytically stable, i.e., a
half-life of greater than 1 year at 25 °C, at pH 7 and 9; whereas at pH
4 the estimated rate constant was 1.46 x 10 -6 with half-life of 198
