Administrative data
Link to relevant study record(s)
Description of key information
Three ready biodegradability tests are available for propylene glycol butyl ether. All tests were conducted under GLP and according to OECD guidelines 301E, 301D and 301B.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Propylene glycol butyl ether showed 90% degradation in the 301 E - modified OECD screening test within the 10 day window and is therefore considered "readily biodegradable".
This data is supported by > 60% degradation of PnB observed in the Closed Bottle Test and the Modified Sturm Test.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
