Any other information on results incl. tables
Fatty acids, C10 -20 neo, reaction product with diethylenetriamine was insoluble in seawater; upon addition to seawater in the mixing jars the majority of the material would float or be caught up in the stirring vortex. During the 48 hour course of the study, normal behavior was observed in the control(s). A twenty four hours of exposure, mortality of one test organism was observed at 1.25mg/L. Complete immmobilization (100%) was observed in the top concentration of 10mg/L, complete mortality was observed in all replicates. The 48 hour EC50 and 95% confidence limits for Fatty acids, C10 -20 neo, reaction product with diethylenetriamine to Daphnia magna were determined to be 2.9mg/L.
Applicant's summary and conclusion
- Conclusions:
- The scope of the study is to evaluate the acute toxicity of water accomodated fractions of Fatty acids, C10 -20 neo, reaction product with diethylenetriamine to
freshwater invertebrates, Daphnia Magna, under static conditions.
Chemical analysis of the water soluble fractions was not performed. All values were based upon nominal concentrations of the substance in test water.
The test substance is an UVCB substance, insoluble in water; upon addition to seawater in the mixing jars the majority of the material would float (relative density: 0.83-1.01) or be caught up in the stirring vortex. Furthermore it has surfactant properties, tends to accumulate at the interfaces and to form aggregates, such as micelles, in the bulk aqueous phase.
These characteristics do not allow to to conduct tests appropriately to obtain exposure of the test species.
The FND ( Fatty Nitrogen Derived) Amides chemicals should be considered to be toxic to aquatic species under conditions that allow contact of the chemicals with the organisms. This toxicity is common not only to the FND Amides chemicals but also to the FND Amines, Cationics, and Nitriles Categories. Further, the high toxicity is consistent with that of a large body of surfactants (e.g. alcohol ethoxylates, alkylphenol ethoxylates, sodium lauryl sulfate, and others).
