Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 contact with water 2-Ethylhexyl acrylate will hydrolyse slowly. Half-life at pH 7 and 25°C was 93.0 h

Key value for chemical safety assessment

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

Additional information

In a hydrolysis study conducted by BASF SE (2015), the half-life of 2 -Propenoic acid, 2 -(diethylamino)ethyl ester in water at pH 7 was determined to be approximately 93 h. At higher pH values hydrolysis was even more rapid (t1/2 at pH 9 = 2.2 h). Therefore, the substance will hydrolyse slowly in contact with water under environmental conditions.
