Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The half-lifes of the test substance at pH 4 and pH 9 were determined to be: 
- at 20 °C: 962 h (pH4) and 65380 h (pH9). 
- at 25 °C: 607 h (pH4) and 28909 h (pH9). 
At pH 7 less than 10 % of the test item was hydrolysed after 5 days at 50°C (t1/2 > 1 year at 25°C)

Key value for chemical safety assessment

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

Additional information

The abiotic degradation of the test item was evaluated via the determination of the hydrolysis rate as a function of the pH-value, according to EU-method C.7 and OECD test guideline OECD 111. At pH 7 less than 10 % of the test item was hydrolysed after 5 days at 50°C (t1/2 > 1 year at 25°C). The half-lifes of the test substance at pH 4 and pH 9 were determined to be: - at 20 °C: 962 h (pH4) and 65380 h (pH9). - at 25 °C: 607 h (pH4) and 28909 h (pH9). Thus the test substance is considered to be hydrolytically stable.
