Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The substance 4-phenylbutan-2-one is soluble in water. Due to its Henry's Law constant of 0.267 Pa · m3/mol it should be considered as relatively non-volatile under environmental conditions. The low octanol-water partition coefficient with a log Pow = 2 shows that the substance has a low potential for absorption to suspended particles or soil. The estimated Koc of the substance is 97.9 L/kg based on the equation proposed by Gerstl (1990). The substance is readily biodegradable.
Based on the identified use patterns, emissions of substance into the environment will mainly occur to the waste water. The substance will be effectively removed from waste water in sewage treatment plants due to rapid biodegradation. The substance will not bind to sewage sludge to a significant extent. A certain fraction of substance may be emitted to surface waters. Partitioning into sediment is not relevant for this substance. Rapid biodegradation in the aquatic environment and slow volatilisation from water surfaces can be anticipated. The substance therefore is regarded as non-persistent in the environment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
