Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Phototransformation in air
After evaporation or exposure to the air, isobutyl acrylate will be rapidly degraded by photochemical processes. The calculated half-life for a 24-hr day and 0.5E+06 OH/cm3 is 27.98 hr.
Hydrolysis
The study does not need to be conducted because the subtance is readily biodegradable (study scientifically not necessary). Nevertheless, a QSAR estimate was conducted. Isobutyl acrylate was predicted contact to hydrolyse slowly
if in contact with water. The calculated half-life at pH 7 and 25 °C is 16.5 years.
Additional information
According to Q(SAR) data using SRC AOP, isobutyl acrylate will be rapildy degraded by photochemical processes after exposure to the air reacting with the photochemically produced hydroxyl radicals and with ozone (calculated half-life for a 24-hour day and 0.5E06 OH/cm3: 27.98 hours; for a 24-hour day and 7E11 O3/cm3: 6.55 days) (BASF SE, 2008).
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.
