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
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.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
