Testing was not carried out according to Method C7 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 for the following
1. The test material was determined, to have a very low water solubility
value of 0.0068 mg/l.
2. As the hydrolysis guidelines require an initial solution
concentration of less than half the water solubility, the test
concentration would need to be even lower than this. On top of that, the
guidelines also require the test material to be analytically measureable
at 10% of the initial test concentration, further increasing the
sensitivity that an analytical method would need to have. Test material
concentrations, even after being extracted to concentrate the samples,
would likely to be less than the limit of quantification.
3. At the low concentration that would be required for the hydrolysis
test, it would possibly be difficult to get near 100% recovery of test
material from the aqueous samples, as seen in the recoveries performed
for the water solubility. Loss of test material may be due to factors
like adsorption to glassware. If sample concentrations got even lower,
then recovery may reduce even further. The main functional groups in the
test material are imides and an amide. Neither of these functional
groups are normally susceptible to rapid hydrolysis under
environmentally relevant conditions, but both are known to hydrolyse
