Description of key information

Study conducted to recognised testing guidelines with GLP.

Additional information

The estimated half-life time of the test substance at pH 4 and pH 7 is higher than one year under representative environmental conditions (25°C). Therefore the test substance was considered to be hydrotically stable at pH 4 and pH 7, and no further testing was necessary.

At pH 9.0 the test substance was not detectable in any of the test solutions during the 50 °C preliminary test.

The test material (EC 438-340-0) was determined to be hydrolytically stable.
