自從奈米科技發展以來，已經研發出許多應用奈米材料之產品，以目前商業趨勢而言， 只要商品名稱被冠上奈米，其附加價值則被大大提高，相對商品價位也提升許多，以化妝 品為例，只要添加奈米材料至化妝品中，除了提高其商品價位外，相對的也使得許多消費 者趨之若鶩瘋狂購買，然而，奈米材料在化妝品的應用還屬新科技，對於人體測試之安全 性及有效性都還沒有初步的報告被發表，甚至有許多消費著迷信奈米產品，而未考慮其安 全性，實在令人堪憂如此濫用奈米材料於化妝品中。 本研究為奈米級二氧化鈦在化妝品工業中之應用，主要針對奈米粒子對皮膚之安全性加 以探討，並討論抗紫外線之有效濃度。Since the development of nano-particles technology , have already researched and developed a lot of products apply nano-particles, as for commercial trend at present, so long as trade named endure the nano-particles on precededding, its additional value is improved greatly, improve the price of the goods too. Take cosmetics as an example, so long as add and use the nano-particles material into the cosmetics, not only improving its goods price, but auso the relative is makes a lot of consumers go after like a flock of ducks and buy crazily too. However, the application of nano-particles in cosmetics is still belongs a new science and technology. It is not all have preliminary report that the endure the application in the cosmetics of nano-particles material issue human body tests is safity and validity. Even a lot of consumption superstition the nano-particles eithin products and has not considered the safity, it ？？ sreally make us worried and abuse the endure nano-particles material in the cosmetics. This work was nano-particles TiO2 of application in cosmetics industry. We studied safety of skin and effect of anti-UV with nano-particles TiO2 mainly, and discuss that resists the ultraviolet effective thickness.
