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.
