Description of key information

At 25°C the  calculated half-life of propylene oxide is 12.9 days in freshwater and 2.4 days in seawater .

Key value for chemical safety assessment

Additional information

Several studies are available on the hydrolysis of propylene oxide. Meylan et al. (1986) determined hydrolysis kinetics of propylene oxide based on various experimentally determined values.At 25°C the calculated half-life of propylene oxide is 12.9 days in freshwater and 2.4 days in seawater . Due to a specific reaction with chloride ions, the hydrolysis rate in seawater is higher.
