The concern of cosmetic industries to ensure products with low environmental impact are increasingly making industry check all its supply chain from raw materials sustainability to biodiversity conservation.Whereas few studies are published on ecotoxicity of cosmetics raw materials, the aim of this work was to propose an integrated environmental impact assessment strategy generated by these substances through evaluation of relevant international parameters. This study considered 40 common raw materials used in rinse-off products, due to their greater environmental exposure concern by defining parameters for risk assessment and effects prediction on aquatic organisms. To analyze the aquatic environmental impact of ingredients the following parameters were evaluated: Bioaccumulation; Biodegradation, Acute Aquatic Toxicity and PEC/PNEC (Predicted Environmental Concentration/Predicted No Effect Concentration), which is the risk quotient that evaluates environmental exposure and aquatic toxicity. Through databases research, scientific literature review, international legislations and also considering parameters established by international agencies, such as Environmental Protection Agency (EPA), Cradle to Cradle (C2C) and European Regulation (EC) No 1272/2008. For unavailable data, in vitro test were done to evaluate biodegradation data, bioaccumulation and acute aquatic toxicity following standardized protocols by OECD (Organization for Economic Co-operation and Development). The results obtained in this study showed strategies and set parameters to integrate different data of cometics aquatic toxicity. It was possible to evaluate different classes of cosmetic’s raw materials and the sunscreens showed the highest environmental impact (Homosalate, Butyl Methoxydibenzoylnethane, Octocrylene, Ethylhexyl Methoxycinnamate and Ethylhexyl Salicylate), followed by the bactericide Triclosan and the emolient Mineral Oil. Therefore, this work proposes an efficient integrated tool to predict the environmental impacts of raw materials of rinse-off cosmetic products, enabling the replacement of ingredients with higher environmental risks, such as the sunscreens, triclosan and mineral oil, making ecofriendly cosmetic products following the main international guidelines
