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).
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
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'.
