Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Additional information
In a hydrolysis study with propylene glycol methyl ether acetate a half life of 8.1 days was calculated at 25°C and at pH 9. At pH 4 and 7, propylene glycol methyl ether acetate is stable.
Biodegradation studies in freshwater and in soil are available for propylene glycol methyl ether acetate. In freshwater, propylene glycol methyl ether acetate can be classified as readily biodegradable based on the results of a manometric respirometry test (OECD GL 301F). In addition several other biodegradation screening studies are available supporting this result. Rapid biodegradation of propylene glycol methyl ether acetate was observed in two different sandy loam soils under aerobic conditions at 25 ± 2 Deg. C. Under anaerobic conditions propylene glycol methyl ether acetate also rapidly degraded to propylene glycol methyl ether.
Based on the existing biodegradation data in freshwater and soil and considering low potentential for adsorption to sediment. No further biodegradation testing in water and sediment is required. According to REACH Annex IX requirements, sediment simulation testing shall only be considered for substances with a high potential for adsorption to sediment, hence no further simulation tests in water and sediment are required for propylene glycol methyl ether acetate.
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.
