Biodegradation studies in freshwater and in soil are available for propylene glycol phenyl ether.

Propylene glycol phenyl ether was shown to be readily biodegradable according to OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test). In the manometric respirometry test (OECD GL 301F) the time required to achieve 10% degradation of propylene glycol phenyl ether was 5.1 days, while the average extent of biodegradation at the end of the 10 day-window was 72%. The formation of CO2 reached 61% CO2, suggesting the extensive mineralisation of propylene glycol phenyl ether.

Rapid biodegradation of propylene glycol phenyl ether was observed in two different sandy loam soils under aerobic conditions at 25±2 Deg. C
