Description of key information
Additional information
Tripropylene glycol n-butyl ether (TPnB) meets the criteria for ready biodegradation, passing the 10 day window in an OECD 301F test (key study). Degradation based on oxygen consumption reached 72% after 10 days. The formation of carbon dioxide reached 56% indication substantial mineralization of TPnB. Extensive biodegradation of TPnB was also observed in an OECD 302B test (Zahn-Wellens test for inherent biodegradability), showing 86, 92, and 96% biodegradation after 14, 21, and 28 days of incubation, respectively. Results of an OECD 301B test also confirmed the biodegradability of the substance.
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).
