Description of key information

In accordance with EC 1907/2006, Annex VIII, point 9.2.2.1, column 2, hydrolysis investigations as a function of the pH are not required since the substance is readily biodegradable.

Key value for chemical safety assessment

Half-life for hydrolysis:
56.7 d
at the temperature of:
25 °C

Additional information

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.
