Safety Assessment of Nanomaterials in Cosmetics

Abstract

Cosmetics need to possess a high level of quality and safety as well as high-functionality responding to consumers' demands, since they are consumer products contributing to quality of life. Nanomaterials, including ultrafine titanium dioxide, have been used to improve the function of cosmetics. Recently, the research concerning the application and safety assessment of nanomaterial has progressed rapidly. Japan Cosmetic Industry Association (JCIA) has conducted original research related to safety of nanomaterials formulated in cosmetics so that the consumer can use them with no safety concerns. This article describes the activities in JCIA regarding safety research on nanomaterials, including the survey on the actual usage of nanomaterials in cosmetics, analysis of the state of nanomaterials present on the skin and toxicological assessment of nanomaterials.
