Description of key information

Propylene glycol phenyl ether meets the criteria for ready biodegradation passing the 10 day window in OECD Guideline 301 F (Ready Biodegradability: Manometric Respirometry Test). Degradation based on oxygen consumption reached 72 % during  10 day window

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

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 CO2reached 61% CO2, suggesting the extensive mineralisation of propylene glycol phenyl ether..
