Description of key information
Additional information
Diphenyl ether has a measured log Kow value of 4.21, indicating a moderate potential for bioaccumulation. However, measured bioconcentration factors (BCF) in fish indicate this potential to be lower than would be predicted from log Kow alone. The U.S. EPA BCFBAF software indicates that measured biotransformation half-life in fish is 0.8 days. Thus, metabolism/excretion is an important mitigating factor for bioaccumulation of this substance. Based on measured BCF values in carp and trout, the substance is regarded as having low potential for bioaccumulation, and does not meet/exceed the Annex XIII criteria for B or vB.
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.
