No long-term toxicity test with aquatic invertebrates is available, but no long-term effects can be expected.
No long-term toxicity test on aquatic invertebrates is available for the
members of the Dimerised Fatty Acids and Its Derivatives category.
However, data on the chronic toxicity to fish do exist for Fatty acids,
C18-unsaturated, dimers, hydrogenated (CAS No. 68783-41-5). A 28-day
study conducted by Marshall (1994) with Danio rerio resulted in no
effects up to the limit of water solubility.
Thus, in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5,a
read across approach is applied, as all substances of the category are
structurally and compositionally related to each other and have similar
properties. It is therefore not expected, as there was no sign that
aquatic invertebrates are more sensitive than fish in short term tests,
that a long-term test with invertebrates will generate different results
than the existing long-term test with fish. In addition and in
accordance to Regulation (EC) No. 1907/2006, 9.1.5., column 2, the
chemical safety assessment according to Annex I indicates no need to
investigate further the effects on aquatic organisms, thus a long-term
study on aquatic invertebrates is not required.
