Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Hydrolysis
On the basis of the experimental studies of the structurally and functionally similar read across chemical and applying the weight of evidence approach, the hydrolysis the test chemical can be expected to be > 5 days at 25°C or > 1 yrs at 50°C at pH 4, 7 and 9, respectively.
Additional information
Hydrolysis
Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the half-life of the test chemical.The studies are as mentioned below:
The half-life of the test chemicalwas 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 4, 7 and 9, respectively. Although the exact half-life value of test chemical was not known, but was reported to be stable during a period of 5 days.Thus, the half-life value of test chemical can be determined to be > 5 daysat a pH 4, 7 and 9 & at a temperature of 25°C, respectively, indicating that the test chemical is 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 50°C. Test chemical was reported to be hydrolytically stable at pH 4, 7 and 9 & at a temperature of 50°C with a corresponding half-life of > 1 years, respectively. Based on this, it is concluded that test chemical is not expected to undergoe hydrolysis under environmental test conditions and thus can be considered to be not hydrolysable.
On the basis of the experimental studies of the structurally and functionally similar read across chemical and applying the weight of evidence approach, the hydrolysis the test chemical can be expected to be > 5 days at 25°C or > 1 yrs at 50°C at pH 4, 7 and 9, respectively. Thus, based on this, it can be concluded that the test chemical is not hydrolysable in water.
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
