Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 main functional groups within the components of the test item are an ester and an amine. Although esters usually hydrolyse readily, especially in alkaline solutions, the test item components may have a significantly reduced hydrolytic rate due to them being essentially insoluble in water. The amine group will be stable. There is also a small amount of amide and alcohol groups. Amides are more hydrolytically stable than the ester, whilst the alcohol will be hydrolytically stable. Overall, these issues make hydrolysis testing unfeasible and testing was not carried out using Method 111 of the OECD Guidelines for Testing of Chemicals (13 April 2004) and Method C.7 Abiotic Degradation, Hydrolysis as a Function of pH of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Additional information

The test item as a whole was expected to be essentially insoluble in water. Therefore the test solution concentration required to dissolve all the components (less than half the water solubility) would be impractically low and a sufficiently sensitive analytical method was not available. The test item is a complex mixture, to which the test method is not ideally suited because each component that is unstable is likely to have its own hydrolytic rate.
