Description of key information

The half life period of allyl acetoacetate in water is 15 days

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The half life period of allyl acetoacetate in water is 15 days and based on this value it can be concluded that the chemical is not persistent in water medium since the half life is less than the threshold of 60 days (to qualify the chemical as persistent). Also the diffusion percentage of allyl acetoacetate in water medium is 38%. This coupled with the dilution of water shall result in ready biodegradabililty of the chemical.
