Key value for chemical safety assessment

Additional information

The registered substance is a UVCB substance consisting of a number of hydrocarbon and oxygenated hydrocarbon components, covering a wide range of carbon numbers and structures, each with their own log Kow value. As such, the generation of a single experimental log Kow value for a UVCB is of limited utility because the environmental risk assessment is performed at the component level. The EPISuite KOWWIN QSAR is a reliable and valid QSAR that was used to model log Kow values for relevant components of the substance. The relevant components were determined based on the best available analytical data and process knowledge (see dossier sections 1.2 Composition and 1.4 Analytical methods). Predicted log Kow values for relevant components of the substance are available in the attached file.
