Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

Under aerobic conditions 81.7 -106.8% 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.

Significant biodegradation was found in a simulation test with natural seawater after 64 days (West et al. 2007). When released into a soil environment monopropylene glycol is expected to biodegrade (98% after 105 days) (The Dow Chemical Company, 1986).

Simulation studies with sediment are not available.
