Oct. 11, 2006 — The Cosmetic, Toiletry, and Fragrance Association (CTFA) released a white paper on the application of nanotechnology in personal care products, including cosmetics and certain over-the-counter (OTC) drug products, specifically sunscreens.

The report discusses the advantages of the use of nanomaterials, the regulatory evaluation of personal care products using nanotechnology, particular properties of nanoparticles, the potential for dermal absorption of nanoparticles used in topical lotions or creams, and what it characterizes as the general scientific consensus and toxicology conclusions about the use of nanotech in personal care products. The report specifically addresses the issue of titanium dioxide and zinc oxide used in nanoparticle form in sunscreens.

The report was announced on Tuesday, the same day the FDA held a meeting to explore safety and other issues surrounding the use of nanomaterials in products. Sunscreens and other skin products using nanoparticles have become a focus point: Some argue they are safe while others argue they pose hazards, or that at least more research needs to be done. The industry-supported report argues that nanoparticles applied topically to the skin in lotions or creams are safe.
