Description of key information
The hydrolysis of the test material as a function of pH was determined by the EU method C7 in the study by Fox and White 2010. The hydrolysis was determined at the physiologically relevant pH of 1.2 and the temperature 37 C.
Key value for chemical safety assessment
- Half-life for hydrolysis:
- 4.68 h
- at the temperature of:
- 37 °C
