Description of key information

A study was conducted according to OECD 301B and EU-method C.4-C and in compliance with GLP to investigate the ready biodegradability of the test item, item ε-Caprolactone, oligometric reaction products with 2,2'-oxydiethanol.

The test item achieved a mean of 90% degradation after 28 days, with a mean of 69% degradation at the end of the 10-day window. Given that the test item is a substance with a complex composition containing different constituents (UVCB) and not a pure substance, the 10-d window consideration may be waived. However, since the test item achieved >60% biodegradation within 28 days and fulfilled the 10 -day window criterion it may be considered to be unambiguously “readily biodegradable within 28 days”.

The test substance, ε-Caprolactone, oligometric reaction products with 2,2'-oxydiethanol is therefore concluded to be readily biodegradable.
