Description of key information
Monopropylene glycol was found readily biodegradable after 28 days under aerobic conditions.
In an OECD306 test (seawater), 96 % biodegradation was observed after 64 days.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Under aerobic conditions, 106.8 % (O2 consumption), 81.7% (CO2 evolution) and 98.3% (DOC removal) biodegradation was found for 100 mg/l monopropylene glycol tested according to OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test) (West et al., 2007) and in another OECD 301 F study 81 -97% biodegradation was found for 84 mg/l monopropylene glycol tested under aerobic conditions (The Dow Chemical Company, 1999). In further assessment monopropylene glycol is considered ready biodegradable. In an OECD306 test (seawater), after 64 days 95.8 % biodegradation was observed (DOC removal) and 90.6% biodegradation was observed (CO2 evolution)(West et al., 2007)
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.
