Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The half life period of allyl acetoacetate in water is 15 days where as in sediment the half life is 140 days
Key value for chemical safety assessment
- Half-life in freshwater:
- 15 d
- at the temperature of:
- 25 °C
- Half-life in freshwater sediment:
- 140 d
- at the temperature of:
- 25 °C
Additional information
Based on the Level III Fugacity Model, the half life period of allyl acetoacetate was estimated. The half life period of allyl acetoacetate in water is 15 days , therfore it is considered that the substance will qualify as not persistent as the half life does not exceed the EPA criteria of 60 days. So, it can be confirmed that the substance is readily biodegradable in water medium where as in sediment the half life is 140 days and based on this value, it can be inferred that the substance is persistent in sediment medium and is not readily biodegradable probably due to the anaerobic conditions existing in most sediments. However, it can be observed that allyl acetoacetate does not diffuse in the sediment medium since it's percentage in the sediment medium is reported to be 0% and hence persistence in the sediment compartment is not likely to be critical.
