Description of key information

Key value determined using EU Method C7 and OECD guideline 111.
The key value is the average half-life at the temperature specified. Full values are detailed in the dicussion.

Key value for chemical safety assessment

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

Additional information

The aim of the study was to examine the hydrolysis behavior of the test substance at pH values normally found in the environment (pH4 – pH 9).

 

The result of the hydrolysis behaviour of the test substance at pH values normally found in the environment (pH 4 – pH 9) are given below:

 

Parameter                        Result

Hydrolysis at pH 4           t ½ = 53 days at 20°C; t ½ = 26 days at 25°C; t ½ = 25 hours at 50°C; t ½ = 11 hours at 60°C

Hydrolysis at pH 7           t ½ = 25 days at 20°C; t ½ = 14 days at 25°C; t ½ = 24 hours at 50°C; t ½ = 16 hours at 60°C

Hydrolysis at pH 9           t ½ = 34 days at 20°C; t ½ = 18 days at 25°C; t ½ = 24 hours at 50°C; t ½ = 15 hours at 60°C
