EC number: 265-198-5 | CAS number: 64742-94-5 A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).

Description of key information
A measured BCF is not available for any streams in this category but as the log Kow of some category members is >3, the bioaccumulation endpoint cannot be waived.Non-polar substances have been shown to have a linear relationship between log Kow and BCF in the log Kow range 1 to 6. Several QSAR have been developed that calculate the BCF of non-polar, hydrophobic compounds on the basis of their log Kow (e.g. Veith et al, 1979 and USEPA, 2008). The method of Veith et al (1979) was used to calculate the BCF for representative substances of the streams since most of the substances fall within the applicability domain of the model.
The calculated BCF for representative components of the streams in this category are in the range 25.9-235.6 l/kg.
The mean of the BCF for the category is 150.1 l/kg and this has been used to complete the 'key value for chemical safety assessment'.
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.
