Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 were carboxylic acids and esters. Carboxylic acids will be hydrolytically stable at environmentally relevant temperatures and pHs. However, esters usually hydrolyse at environmentallly relevant temperatures and pHs and it would be expected that the test item would hydrolyse at environmentally relevant temperatures and pHs.

Key value for chemical safety assessment

Additional information

The test item is a complex mixture for which the test guidelines for hydrolysis are not recommended because components could have different hydrolytic rates that give rise to non-pseudo first order hydrolysis plots. In addition, hydrolysis products can be analytically indistinguishable from the starting components because larger components hydrolyse to hydrolysis products that have the same structure as components already within the test item.
