Description of key information

The hydrolysis rate was determined according to the test OECD Guideline 111.
The substance was found to be hydrolytically stable at 25°C, with estimated half-live greater than 1 year at pH 4 and 366 h at pH 7.

Key value for chemical safety assessment

Half-life for hydrolysis:
366 h
at the temperature of:
25 °C

Additional information

The hydrolysis rate was determined according to the test OECD Guideline 111.

The substance was found to be hydrolytically stable at 25°C, with estimated half-live greater than 1 year at pH 4.

Advanced tests results were the following:

Kobs = no data, t½ > 1 a at 25°C for pH 4.0,

Kobs = 5.26 x 10-7 s-1 and t½ = 366 h at 25°C for pH 7.0,

Kobs = 4.42x10 -5 s-1 and t½ = 4.36 h at 25°C for pH 9.0.
