Additional information

Based on the final test results, it can be concluded that Condensation product of N-C12-C18-alkylpropane-1,3-diamine, N-(3-aminopropyl)-N’-C12-C18-alkylpropane-1,3-diamine and formic acid is very toxic to algae with ErC50 of 37.8 µg/L and a NOEC of 5.56 µg/L (measured concentrations). The study was carried out in accordance with OECD guideline 201. The study was GLP certified and validity criteria were fulfilled.
