Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, section 9.2.2.1, a study on hydrolysis does not need to be conducted as all long-chain alkyl esters (C12 - C14) are readily biodegradable. Further the water solubility of teh long-chain alkyl esters is very low (< 1 µg/L at 20 °C).
Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Regulation (EC) No 1907/2006, section 9.2.2.1, a study on hydrolysis does not need to be conducted as all long-chain alkyl esters (C12 - C14) are readily biodegradable. Further the water solubility of the long-chain alkyl esters ist very low (< 1 µg/L at 20 °C)
Nevertheless a supporting study of hydrolysis of the test substance 2 -Propenoic acid, C12 -14 -alkyl esters the hydrolysis of the test substance was performed through a calculation using HYDROWIN v2.00. The estimated half-life at pH 8 is 2.38 years and the estimated half-life at pH 7 is 23.8 years.
The test compound lacks a functional group that is hydrolytically reactive.This low potential to hydrolyze is supported by the data developed using the HYDROWIN model (see above).Thus, hydrolysis will not significantly contribute to the removal of laurylacrylate from the environment.
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.
