Description of key information

Additional information

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.

Propylene glycol methyl ether acetate is readily biodegradable in freshwater with a low potential for adsorption to sediment. Based on the distribution modeling (Level III fugacity model), most of the substance released directly to water will remain in the water compartment and is expected to be biodegraded. The risk assessment shows that the PEC/PNEC ratios for sediment are clearly < 1, indicating no need for further information or testing. According to REACH Annex IX requirements, sediment simulation testing shall only be considered for substances with a high potential for adsorption to sediment, hence a simulation test in water and sediment can be waived for propylene glycol methyl ether acetate.
