Description of key information

A study was conducted to investigate the biodegradation of Cycloaliphatic Epoxide Resin ERL-4221. The study was in accordance with OECD Guideline 301B. 
The % biodegradation is expressed as a ratio of evolved carbon dioxide to the initial theoretical carbon added as test substance. The initial concentration of the test substance (Cycloaliphatic Epoxide Resin ERL-4221) was 20 mg C L-1. The test substance achieved 71 % biodegradation in 28 days but did not achieve the pass level of 60 % in the 10 day window. Therefore Cycloaliphatic Epoxide Resin ERL-4221 can be classified as readily biodegradable (but not passing the 10 day window).

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable but failing 10-day window

Additional information

Cycloaliphatic Epoxide Resin ERL-4221 can be classified as readily biodegradable (but not passing the 10 day window).
