Description of key information

An abiotic degradation (hydrolysis) study at 50 Celsius, at 3 different pH values, gave only very weak hydrolysis

Key value for chemical safety assessment

Half-life for hydrolysis:
1 mo
at the temperature of:
50 °C

Additional information

Half-life of hydrolysis of DPGEE was not determined in this study but at 5 days degradation/loss of 4.93% at pH 4 and 5.35% at pH7 and 0% at pH 9 was seen. Hydrolysis rate constants cannot be estimated for compounds of this type using HYDROWIN v2.00 (EPA EPISUITE).
