Description of key information

The preliminary test (Tier 1) was performed for the determination of the rate of hydrolysis of DEGMEE at pH values normally found in the environment (pH 4-9).
At each pH value a degree of hydrolysis of < 10% was observed after 5 days. According to the guideline, performance of the main study (Tier 2) was not required.
The half-life time of the test substance at 25°C was > 1 year at each pH

Key value for chemical safety assessment

Half-life for hydrolysis:
1 yr
at the temperature of:
25 °C
