  • Slide 51 - Nanopowder Nanopowder are solid particles that measure on the nanoscale, usually comprised of three to five molecules together. Nanopowder have been of extreme interest in the Cosmetic field. Smaller particles mean better absorption by the body therefore less drug is needed. Because of a combination of these, side effects are lessened due to better use of cosmetics. 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 51
  • Slide 52 - Nanopowder 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 52
  • Slide 53 - Nanoencapsulation and controlled release Such nanosized particles which have a shell and an interior space that can be used to load drugs are called nanocapsules. Different types of nanocapsules are required depending on the nature of the material (hydrophobic or hydrophilic) to be incorporated. Polymers have been widely used to create nanocapsules which are then functionalised for various applications. 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 53
  • Slide 54 - Nanoencapsulation and controlled release 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 54
  • Slide 55 - Cubosomes Cubosomes are nanostructured particles of bicontinuous cubic liquid crystalline phase. Bicontinuous cubic liquid crystalline phase is an optically clear, very viscous material that has a unique structure at the nanometer scale. They have high heat stability and are capable of carrying hydrophilic and hydrophobic molecules. They are an attractive choice for cosmetic applications as well as for drug delivery. 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 55
  • Slide 56 - Cubosomes 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 56
  • Slide 57 - Nanotechnology for UV protection Zinc oxide (ZnO) and titanium dioxide (TiO2) particles have been widely used for many years as UV filters in sunscreens. Products using nanoparticles of ZnO or TiO2 are transparent so have increased aesthetic appeal, are less smelly, less greasy and more absorbable by the skin. Many sunscreens and moisturisers available now use these nanoparticles, including products from Boots, Avon, The Body Shop, L’Oréal, Nivea and Unilever. 14/12/2011 Birla Institute of Technology, Mesra, Ranchi. 57
