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.

Hydrolysis

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.
