Nanotechnology is an innovative science that includes the design, characterization, production and application of structures, devices and systems by controlling shape and size at the nanometer scale, which covers the size range from 1 nanometer to 100 nanometer (nm), where 1 nanometer is 1 billionth of a meter. It is not news to cosmetic companies that nanotechnology is the way of the future and is considered as the hottest and emerging technology available. Cosmetic manufacturers use nanoscale versions of ingredients to provide better UV protection, deeper skin penetration, long-lasting effects, increased color and finish quality etc. The global market for cosmetics using nanotechnology is projected to reach an estimated $155.8 million in 2012.[1] This widespread use of nanoscale materials in cosmetics is due to the fact that these nanoparticles obtain newer properties which differ from the large-scale particles. These altered properties include color, transparency, solubility and chemical reactivity, making the nanomaterials attractive to the cosmetics and personal care industries
