Abstract

Alternative methods, replacing animal testing, are urgently needed in view of the European regulatory changes in the field of cosmetic products and their ingredients. In this context, a joint research initiative called SEURAT was recently raised by the European Commission and COLIPA, representing the European cosmetics industry, with the overall goal of developing an animal-free repeated dose toxicity testing strategy for human safety assessment purposes. Although cosmetic ingredients are usually harmless for the consumer, one of the initial tasks of this research consortium included the identification of organs that could potentially be affected by cosmetic ingredients upon systemic exposure. The strategy that was followed hereof is described in the present paper and relies on the systematic evaluation, by using a self-generated electronic databank, of published reports issued by the scientific committee of DG SANCO responsible for the safety of cosmetic ingredients. By screening of the repeated dose toxicity studies present in these reports, it was found that the liver is potentially the most frequently targeted organ by cosmetic ingredients when orally administered to experimental animals, followed by the kidney and the spleen. Combined listing of altered morphological, histopathological, and biochemical parameters subsequently indicated the possible occurrence of hepatotoxicity, including steatosis and cholestasis, triggered by a limited number of cosmetic compounds. These findings are not only of relevance for the in vitro modeling efforts and choice of compounds to be tested in the SEURAT project cluster, but also demonstrate the importance of using previously generated toxicological data through an electronic databank for addressing specific questions regarding the safety evaluation of cosmetic ingredients.
