Additional information

There are two available studies in order to determine the acute toxicity of the substance to daphnia. One study belongs to the same substance CAS 1195028 -55 -7 and the other one to the CAS 1325 -54 -8, which is the identical structure in respect to the anionic components. Both studies demonstrate that the substances have an EC50 for freshwater invertebrates > 100 mg/l.

The test results from the substance CAS 1325 -54 -8 shows that up to the highest concentration tested of 1000 mg test substance/l no toxic effect on Daphnia magna was observed. As the maximum concentration tested (EC50 daphnia)<100mg/l) no death was observed, the EC50(daphnia) could be considered assimilable at water solubility 149000 mg/l according OECD guideline. Therefore, the test substance is considered not to be harmful to daphnia.
