Apart from the toxicity and related regulatory aspects of nanotechnology-based products, public
opinion and attitudes towards nanotechnology are extremely important for the development of this
emerging branch of science and industry. Our willingness to take risks is most probably lower for
products that are in direct contact with our bodies and that are not vitally important. Thus, when
cosmetics go nano, the need for reliable scientific reports confirming both the benefits and safety
are likely to become crucial for the success of the scientific results and inventions described in this
report and those that are in the pipeline.
