CAS number: -
Substance is not bioaccumulative on the basis of available data.
The substance is a hydrocarbon UVCB.
Assessment using the US EPA On-Line EPI Suite™ KOWWIN version 1.68
model, the log Kow range is predicted to be 7.49 to 31.33.As
the substanceshows log Kow values
in the main of > 10,it is
proposed that the substance is not indicative of being potentially
bioaccumulative, on the basis of the partition coefficient values
The substance is, however, considered to
be not bioavailable to aqueous organisms as demonstrated by the lack of
toxicity. Furthermore, the high log Kow is considered to be more a
consequence of poor water solubility than a lipophilic tendency and is
considered to be not indicative of the tendency to bioaccumulate in
lipid tissues of aquatic organisms. This is based in part on an
evaluation of literature data which demonstrates a tendency for the
Bioconcentration Factor (BCF) to decrease as Log Pow increases above 6.
This assumption is further confirmed by the data set available on the
substance which demonstrates that it is poorly absorbed, both on the
basis of the toxicity (or lack of) observed, plus the absorption study
which demonstrated the lack significant absorption in the rat.
The above opinion is also confirmed via
use of the EPIWIN BCFBAF v3.01 for assessment of bioaccumulation. The
smallest and largest theoretical molecular weight substances were
assessed and the following results were demonstrated:
Smallest: BCF 1944 L/kg wet-wt
Largest: BCF 3.162 L/kg wet-wt
All evaluated values are less that
<2000, indicating that the substance is not proposed to be
Evaluation of predicted molecular size
data indicates that approximately 29% of the molecules are of a Dmax
average of greater than 17 Å (1.7 nm) plus a molecular weight of greater
than 700 (Da).
Taking into account the following:

size data not being indicative of the propensity towards bioaccumulation.
This indicates, within a weight of
evidence approach and with expert judgment, that NovaSpec Renewable
White Oil is deemed to not be bioaccumulative in aquatic organisms.
