Description of key information
Hydrolysis
On the basis of the experimental studies of the test chemical and applying the weight of evidence approach, the hydrolysis half-life value of the test chemical can be expected to be 44 days at pH 5.0 and it was reported to be hydrolytically stable at pH 7 & 9, respectively or 622 days at pH 4 and at a temperature of 25⁰C. Thus, based on this half-life value, it can be concluded that the test chemical is not hydrolysable.
Additional information
Hydrolysis
Data available for the test chemical has been reviewed to determine the half-life of hydrolysis as a function of pH. The studies are as mentioned below:
The half-life of the test chemical was determined at different pH range. The study was performed at pH of 5, 7 and 9, respectively. The half-life period of test chemical was determined to be 44 days at pH 5.0 and test chemical was reported to be hydrolytically stable at pH 7 and 9, respectively. On the basis of this, test chemical is considered to be not hydrolysable.
In an another study, the half-life of the test chemical was determined at different pH range. The study was performed according to OECD Guideline 111 (Hydrolysis as a Function of pH) at a temperature of 25°C and pH of 4, 7 and 9, respectively. The half-life period of test chemical was determined to be 622 days at pH 4, respectively. Thus, test chemical was reported to be hydrolytically stable at pH 4 and at a temperature of 25⁰C. On the basis of this, test chemical is considered to be not hydrolysable.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
