Description of key information
Substance is not bioaccumulative on the basis of available data.
Additional information
Bioaccumulation Study in Carp using SynNova® Base Oil
The BMF of the quantitative components (dimer, peak A) was less than 0.007, which is the criterion for bioconcentration potential under the Chemical Substances Control Law. No significant peak of the monitored components (trimers, peak B) was detected from fish samples. The BMF of the reference substance was 0.0244 for the test group and 0.0153 for the control group. Since these results were similar to the already known BMF value of 0.0343* of the reference substance, it was judged that the test was conducted properly.
It can be concluded from the above results that the bioconcentration potential of the test substance in fish is not high.
* BMF value after 13 days of exposure period described in the test guideline.
Bioaccumulation Study in Rare Minnow using SynNova® Base Oil
Under the test conditions, after a 14 day uptake phase exposure test, the 500 mg test substance / kg food was calculated as biomagnification factor (BMF) for Gobiocypris rarus as less than 0.00296
The substance is read across to the analogous substance, Partially hydrogenated β-3,7,11-trimethyldodeca-1,3,6,10-tetraene, reaction products with linear C8-C16 alpha olefin, hydrogenated. This substance is a base oil, deemed to be a "white oil". There is no significant bioaccumulation associated with this category of substances.
This is further reinforced by assessment of the properties of the substance. The substance is 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.
The above opinion is also confirmed via use of the EPIWIN BCFBAF v3.01 for assessment of bioaccumulation of BCF 3.162 L/kg wet-wt the evaluated values are less that <2000, indicating that the substance is not proposed to be bioaccumulative.
Evaluation of predicted molecular size data indicates that approximately 11% 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:
· Lack of absorption
· Lack of persistency
· High predicted log Kow value.
· Low predicted bioaccumulation potential
· Molecular size data not being indicative of the propensity towards bioaccumulation.
This indicates, within a weight of evidence approach and with expert judgment, that SynNova® Base Oils deemed to not be bioaccumulative in aquatic organisms.
