NANOMATERIALS AND COSMETICS

Abstract

SUMMARY This review has overviewed the nanotechnology approaches and safety concerns in cosmetics. Nanotechnology based nanomaterials have been widely use in cosmetics for recent few years such as in sunscreens, hair products, skincare products, etc. However debate on their definition and insufficient quantification methods are major problems still occur in the nanomaterial field. Moreover the frequent use of cosmetics, safety of nanoscale ingredients of them has gain importance mainly by means of their dermal exposure. Although the proposed benefits that may occur by incorporating nanoparticles in cosmetics are increased efficiency, transparency, unique texture, protection of active ingredient, and overall higher consumer compliance, there still have not enough studies proved whether they are completely safe or not. As a conclusion major issues related nanomaterials such as developing, using and researching is going to increase in the near future due to their economically importance. Key words: Nanotechnology, nanomaterial, dermal, safety, cosmetics. *Correspondence: evrenalgin@yahoo.com, algin@pharmacy.ankara.edu.tr
