Description of key information

Determination of the hydrolytic stability of TK 11907.

Key value for chemical safety assessment

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

Additional information

Hydrolysis as a Function of pH: Assessment of hydrolytic stability was carried out using a procedure designed to be compatible with Method C7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008, and Method 111 of the OECD Guidelines for Testing of Chemicals, 13 April 2004. The results are as follows:
