Nanofacts: Nanomaterials in Cosmetic Products

Nanos und Kosmetika

Like many other products in everyday use (food, medicines, clothing, etc.), some cosmetics also contain ingredients in nano form. For example, nano-titanium dioxide or nano-zinc oxide are found in sunscreens or cosmetic products with a sun protection factor. Both compounds are used for mineral / physical sun protection (UV filters). By using them in nano form, it is possible to design thinner creams that are easier to spread on the skin and thus increase protection.

Other lotions, as well as deodorants and soaps, also contain nanomaterials. First and foremost, nano-silver should be mentioned. The precious metal is used here because of its antibacterial effect. It prevents unpleasant odors and has a disinfecting effect. In nano form, it has a particularly long service life, as the effective silver ions can be released over a longer period of time.

Since July 2013, cosmetics containing ingredients in the form of nanomaterials must be labeled with the word "nano" - in brackets after the ingredient. This is because if a cosmetic product contains nanomaterials, the manufacturer must identify the nanomaterial during EU registration in the Cosmetic Product Notification Portal (CPNP).

Anyone with a more in-depth interest in nanomaterials in cosmetics will find more information at the EUON (European Union Obeservatory for Nanomaterials) homepage provides detailed information on other NMs, e.g. in the Cosmetic Ingredients Catalog.
