Description of key information
Additional information
Partially unsaturated IQAC, DMS quaternised is a complex mixture of similar substances. The variation is not only due to different chain lengths, but also due to varying structures (see 1.2). The water solubility of the corresponding constituents is low, whereas the adsorption potential of the constituents is very high (see 4.2.1). The experimental water solubility of 2.6 mg/L at 22 ºC (pH 5.1) was determined by the slow stirring method (see 1.3). In the frame of the study to determine the water solubility, the column elution method was applied. In determining water solubility of the substance with this method considerable problems occurred. Very low water solubilities were determined, presumably due to the very high adsorption onto the glass bodies of the column. Therefore the analytical determination of the individual constituents would be very complex and in case of ecotoxicological tests not operable. In the ecotoxicological tests with Daphnia magna (Evonik 2010 ...) and Algae (Evonik 2010...) it was observed that the analytically determined concentrations of the waf (water accommodated fractions) did not correlate with the loading rates and correspond only to some of the constituents.
As a consequence the reported effect concentrations are nominal values based on loading rate. Loading rates grant the reliable correlation between ecotoxicological effects and the amount of the substance in a distinct water volume. Using loading rates allows the comparison of complex mixtures of low water solubility with highly water soluble pure substances on the same base.
Loading rates are more realistic values for the hazard assessment, because a direct extrapolation from the amount of the substance per volume to a real situation is allowed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).
