Developing a complex methodology of ecotoxicological characterization of some commercial detergents, in accordance with European Regulation EC648 / 2004 and subsequent amendments

Abstract

The new European legislation on detergents initiated a comprehensive test strategy, for the surfactants biodegradability assessment, depending on the use of detergents (for consumers or industrial and institutional use). For the implementation of 648/2004 (EC) Regulation and considering the reduced number of test / evaluation methodologies that can be performed currently at national level, the project initiated the development of a complex methodology of ecotoxicological assessment of commercial detergents (especially for products that contain cationic and amphoteric surfactants), in accordance with European Regulation EC648 / 2004 and subsequent amendments. Moreover, it has followed the development / implementation in the laboratory of modern and advanced analytical techniques (chromatographic methods) to determine selective cationic and amphoteric surfactants in aqueous solutions.
