Description of key information

The hydrolysis of the test item was assessed in aqueous buffers at pH 1.2, 4, 7 and 9 at 50 ± 0.5°C according to the OECD testing guideline 111.


After 5 days, at pH 4, the test item was shown to be hydrolysed by less than 10% compared to T0. This indicated that it was hydrolytically stable and significant hydrolysis had not occurred under these conditions.


At pH 7, the test item was shown to be hydrolysed by slightly more than 10% compared to T0. The disappearance of the test item was not considered significant. Consequently, the definitive test was conducted at pH 1.2 (37°C) and 9 (15, 37 and 50°C).


The half life of the test item at pH 1.2 and 37°C was determined as 4 days.


The half life of the test item at pH 9.0 and 25°C was determined as 4.8 days.


The substance bis (hydroxymethyl) tricycle decane was identified as a hydrolysis product.
