Description of key information
Additional information
The substance 4-phenylbutan-2-one is readily biodegradable. The 14-day window was fulfilled in the available screening study on ready biodegradability (closed bottle test). The substance is considered rapidly degradable in the environment. No environmental persistence of the substance is anticipated. The log Kow value of 2 indicates a low potential for bioaccumulation of the substance. Additionally, the substance has low potential for adsorption to soil or suspended particles and is classified as highly mobile in soil. Taking into account the use pattern of the substance, it is predicted that the greatest fraction of substance will be released to the waste water. A significant fraction will be removed from waste water by biodegradation during waste water treatment. A small fraction may be released to surface water, where biodegradation is likely to continue. The substance is slightly volatile and may evaporate slowly from water surfaces to a small extent. Adsorption to sludge or sediment to any significant extent is not to be expected.
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.
