Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 air, 2-hydroxyethyl acrylate will be rapidly degraded by photochemical processes. The substance has an estimated half-life in air of ~25.33 hours. As the cut-off time for reaching the stratosphere is 2 days, the substance is considered to have no potential for reaching the stratosphere and/or long-range atmospheric transport.


The study does not need to be conducted as the substance is readily biodegradable. In contact with water at neutral pH no hydrolysis of 2-hydroxyethyl acrylate will be observed. In alkaline water, the substance will hydrolyse rapidly.

Phototransformation in water and soil

Data on photodegradation in water and soil are not required under REACh.
