Cosmetic Industry Releases Scientific White Paper on Use of Nanoparticles in Personal Care Products Report Discusses Science Behind the Benefits of Nanotech

    WASHINGTON, Oct. 10 /PRNewswire/ -- The Cosmetic, Toiletry, and
 Fragrance Association (CTFA) released today a scientific white paper on the
 application of nanotechnology in personal care products, including
 cosmetics and certain over-the-counter (OTC) drug products, specifically
     The report, available at, 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 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.
     "This report directly addresses the science behind the use of
 nanoparticles in personal care products," said John Bailey, Ph.D.,
 executive vice president of science at CTFA. "The science strongly
 indicates that nanoparticles applied topically to the skin in lotions or
 creams are safe and provide clear benefits to consumers."
     Sunscreens, some of which utilize sun-protecting nanoparticles that
 help prevent skin cancer, are required to go through an extensive FDA
 review and approval process to demonstrate they are safe and effective. The
 nanoparticles in sunscreens, titanium dioxide and zinc oxide, are
 established, efficacious sunscreen filters that have been on the market for
 decades. In 1996, FDA concluded that smaller, micronized particles of
 titanium dioxide are not new substances and that there is no evidence
 demonstrating that these micronized particles are unsafe. Nano-sized
 titanium dioxide and zinc oxide, unlike the larger particle size
 ingredients, form a transparent rather than a thick, white coating, which
 leads to greater consumer acceptance and use of the products, and therefore
 greater protection from skin cancer and other damaging effects of the sun.
 The nano-size of the particles also enables them to better reflect and/or
 scatter certain harmful UV rays.
     "The nanoparticles used in sunscreens provide important and unique sun-
 protection benefits, helping reduce the risk of skin cancer," Bailey said.
 "These sunscreen ingredients have been used safely for many years and have
 been evaluated and approved by the FDA and independent scientists. They are
 transparent and aesthetically pleasing and therefore encourage greater
 consumer use."
     In addition to the report released today, CTFA also filed comprehensive
 comments with the Food and Drug Administration (FDA) on the science and
 regulation of nanoparticles in personal care products. CTFA comments, which
 can be found at, specifically address issues raised in
 a petition filed with FDA earlier this year on nanotechnology applications
 in personal care products, specifically sunscreen products.
     Based in Washington, D.C., CTFA is the trade association representing
 the cosmetic, toiletry, and fragrance industry in the United States and
 globally. Founded in 1894, CTFA has a membership of approximately 600
 companies including manufacturers, distributors, and suppliers of the vast
 majority of finished personal care products marketed in the United States.
