In accordance with EC 1907/2006, Annex VIII, point 18.104.22.168, column 2, hydrolysis investigations as a function of the pH are not required since the substance is readily biodegradable.
A valid GLP OECD 111 key
study shows that the substance is stable at pH 4 and 7 (DT-50 > 1 year).
At pH 9, the extrapolated DT-50 at 25°C is 56.7 days. Hence abiotic
decomposition is base catalyzed. Stability during 2 days in aqueous test
solutions for a OECD 202 study, i.e. at 20°C and pH 7 to 8 is confirmed
by a valid experiment under GLP.
