Description of key information
Zinc naphthenate consists of zinc salts of naphthenic acids and in the aquatic environment is expected to dissociate into zinc cations and naphthenic acid components. Zinc is an essential element which is actively regulated by organisms, so bioconcentration/bioaccumulation is not considered relevant. The ranges of BCF values are the result of active regulation mechanisms that keep the internal zinc concentration of the organisms within an optimal range. For the naphthenic acid component, QSAR estimates are provided showing the bioaccumulation potential of representative structures. The BCF of the representative constituents of zinc naphthenate are estimated by QSAR to be in the range of 3.162 to 207.7 L/kg ww.
Additional information
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.
