After use, a number of Lion products are discharged into the environment after passing through sewage treatment plants. To ensure there are no substantial environmental effects, we evaluate ingredients in the early stages of product development to determine the extent to which they are readily biodegradable and their effect on different aquatic species.
Leveraging our extensive accumulated data and verified external information, we assess the environmental effect of each new ingredient. If the available information is insufficient, we conduct tests to gain a firm understanding of the ingredient’s biodegradability and the effect on organisms within an ecosystem’s food chain, including algae, water fleas and fish. In addition, we utilize new technologies, including liquid chromatography–mass spectrometry (LC–MS) for in-depth biodegradation pathway analysis as well as computer simulations to estimate concentrations in river water.
Moreover, we actively participate in the Japan Soap and Detergent Association’s monitoring of major Japanese rivers, focusing on widely used surfactants with high production volumes, to confirm that their concentrations remain at environmentally safe levels after entering into the market.
