Abstract

  Cosmetics are consumer products intended to contribute to increasing quality of life and designed for long-term daily use. Due to such features of cosmetics, they are required to ensure quality and safety at a high level, as well as to perform well, in response to consumers' demands. Recently, the technology associated with nanomaterials has progressed rapidly and has been applied to various products, including cosmetics. For example, nano-sized titanium dioxide has been formulated in sunscreen products in pursuit of improving its performance. As some researchers and media have expressed concerns about the safety of nanomaterials, a vague feeling of anxiety has been raised in society. In response to this concern, the Japan Cosmetic Industry Association (JCIA) has begun original research related to the safety assurance of nanomaterials formulated in cosmetics, to allow consumers to use cosmetics without such concerns. This paper describes the activities of the JCIA regarding safety research on nanomaterials, including a survey of the actual usage of nanomaterials in cosmetics, analysis of the existence of nanomaterials on the skin, and assessment of skin carcinogenicity of nano-sized titanium dioxide. It also describes the international status of safety assurance and regulation regarding nanomaterials in cosmetics.<br>
