Although the test results would strictly fit the criteria for R53/H413
environmental classification, it is in our opinion not applicable for
this substance for the following reasons:
As stated in section 5.2.1, the results of the Modified Sturm test
cannot be interpreted because the tested concentration was far above the
maximum water solubility. Thus, in view of lack of the optimal contact
between the test substance and the medium in the test, no definitive
conclusions can be drawn with respect of biodegradability of the test
Furthermore, an enhanced ready biodegradation test is technically not
possible as the test substance is a waxy solid which could not be
dissolved in any common organic solvent or mixtures of solvents.
The estimated logPow value for the substance > 10, together with the
high molecular weight range of the test substance (1763 - 2891, see
reference substance) indicate a limited bioavailability of the substance.
Because no quantitative analysis of the test substance in water or corn
oil could be developed or validated (see section 8), any further testing
to prove the lack of long-term toxicity or bioaccumulation in the
aquatic environment is not deemed appropriate.
Based on the reasons stated above, we strongly believe that the
substance should not be classified.
