Nanotechnology for Cosmetics

Abstract

In the present chapter, different types of nanomaterials used in various cosmetics have been discussed. Such materials can act as active components for antibacterial activity (such as silver nanoparticles), nanopigments for enhanced adsorption, and UV filters (zinc oxide nanoparticles). Furthermore, such nanomaterials can also be employed as nanocarriers, e.g. nanoliposomes, niosomes, solid lipid nanoparticles, metal-based nanoparticles and polymeric nanoparticles, or as formulations. All such aspects of these nanomaterials have been discussed in detail. Finally the pros and cons of such nanomaterials in cosmetics along with a conclusion have been provided in the last section.
