Description of key information
A GLP-study with a well described method is available for propylene glycol methyl ether.
Key value for chemical safety assessment
- Half-life in soil:
- 1 d
- at the temperature of:
- 293 K
Additional information
Rapid biodegradation of propylene glycol methyl ether was observed in two different sandy loam soils under aerobic conditions at 25±2 Deg. C. The time required for 50% degradation of the parent compound ranged from less then 1 day at 1 ppm to less than 7 days at 100 ppm. Degradation rates were slower in sand, reflecting the lower concentration of microorganisms present. No significant accumulation of intermediate degradation products was observed . Ultimate yields of 14CO2 ranged from 31 to 76% of the initially applied radioactivity.
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.
