It has been found out from different surveys that almost all the major cosmetic manufacturers use nanotechnology in their various products. Cosmetics giant Estee Lauder entered the NanoMarket in 2006 with a range of products containing “NanoParticles”. L’Oreal, the world's largest cosmetics company, is devoting about $600 million dollars, of its $17 billion dollar revenues, to Nano patents, and has patented the use of dozens of “nanosome particles”. It ranks number 6 in nanotech patent holders in the U.S.[3] Other examples include Freeze 24/7, DDF (Doctor's Dermatologic Formula), and Colorescience.[4] An estimation of how the top 10 cosmetic companies of the world rank in terms of nano-related patents, based on Espacenet database
