Description of key information

Additional information

Several aquatic toxicity tests have been performed on Mackam LSB-50, aqueous solution of the registered substance in water which exhibits an active content of ca. 35.6%. The observed toxicity effects in these tests are expected to be the result of the exposure of aquatic organisms to active content.

Studies were performed on freshwater species and/or on saltwater species, according to standardized guidelines and are all considered as valid.

The three main trophic levels (fish, invertebrates and algae/aquatic plants) were covered regarding acute toxicity and according to available data, Daphnia magna is considered as the most sensitive species for acute effects. Only two trophic levels covered the chronic toxicity and Daphnia magna is also considered as the most sensitive species for chronic effects. No chronic toxicity data are available on fish but fish are considered as the less sensitive species regarding to acute effects and thus it is expected that fish will not present higher toxicity than algae and invertebrates for chronic exposure.

Based on all available data, Lauramidopropylhydroxysultaine is considered as toxic to aquatic life.
