Chapter 22 – Nanotechnology in Cosmetics

摘要: Nanotechnology is a novel expanding area of research involved in manipulating properties and structures at nanoscale. Nanoparticles have recently received considerable attention medical, biomedical, biotechnological applications emerged the fields cosmetics dermal preparations. This chapter introduces cutting-edge science related to nanoparticles' role cosmeceutical industry. It starts by presenting skin structure function. then explains mechanisms nanoparticle permeation through including transcellular, intercellular, transappendageal pathways. Various ingredients used beauty care products their nanoformulations are discussed. A full discussion main nanoparticles that been presented. The toxicity nanoparticles, safety requisites for these products, regulation described.
