[Abstract]
In order to understand the percutaneous exposure and overall risk of nanomaterials when applied on skin, and to discuss the application of percutaneous absorption data in safety evaluation of nanomaterials, in this article, the authors summarized related research studies and safety evaluation work of five nanomaterials, such as triphenyltriazine, zinc oxide, carbon black, titanium dioxide, methylene bis benzotriazolyl tetramethyl butylphenol, that had been included in the EU regulation. The results show that skin is an effective barrier for these nanomaterials. In the future, for percutaneous absorption study of nanomaterials, as well as for the safety evaluation of nano-cosmetics and skin-applied nano-drugs, the influence of skin barrier function should not be ignored, and a case-by-case analysis with consideration of key parameters of the nanomaterial is necessary.
