Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
Based on the results of the studies, ethylene glycol hexyl ether can be classified as "Readily Biodegradable"
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Ethylene glycol hexyl ether was subjected to biodegradation testing following carbon dioxide evolution test methodologies (OECD301B and EPA.Biodegradation was measured in these tests by collecting the carbon dioxide(C02)generated during bacterial degradation of the tested product, and calculating this as a percentage of the predetermined maximum potential C02. 96.8 % degradations was observed at the end of 20 day also passing the‘10-day window' criteria. Ethylene glycol hexyl ether meets the OECD and EPA criteria for classification as 'Readily Biodegradable’.
Supporting studies according to or similar to OECD guidelines 301E, 302B and a BOD test also report rapid biodegradation of ethyl glycol hexyl ether supporting the classification of ethylene glycol hexyl ether as "readily biodegradable".
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.
