Description of key information

1,6-Hexanediol dimethacrylate is classified as readily biodegradable according to OECD 301 F (manometric respiratory test). The 10-day criterion for ready biodegradability was met. (Evonik Röhm GmbH, 1998)

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

In a valid guideline study according to OECD 301 F (manometric respiration test) 1,6 -Hexanedioldimethacrylate was exposed to microorganisms derived from activated sludge of a municipal sewage treatment plant under aerobic static conditions. The biodegradability of 1,6 -Hexanedioldimethacrylate was determined to be 91.1 % after 28 days based on O2 consumption as compared to the theoretical O2 demand (ThOD). Since 1,6 -Hexanedioldimethacrylate reached 82.3 % of degradation at the end of the 10-d window it reached the pass level of 60 % for ready biodegradability and is therefore classified as readily biodegradable in the Manometric Respiration Test.
