Applications of Nanoparticles in the Cosmetic Field

Abstract

Nanotechnology is a cutting-edge scientific discipline that focuses on manipulating matter at the nanoscale scale to create new and useful materials, gadgets, and systems (1–100 nm). One of the most rapidly expanding, and commercially viable niches in the cosmetics industry is the use of micellar nanoparticles in these products. The improved qualities of the nano-sized particles in terms of colour, transparency, solubility, etc., are largely responsible for the extensive impact of nanotechnology in the cosmetics sectors. Cosmetics use a wide variety of nano materials, including nanosomes, liposomes, fullerenes, solid lipid nanoparticles, etc. Recent worries about the potential dangers of nano cosmetics have prompted the cosmetics industry to restrict the use of nanotechnology in cosmetics and push for stricter regulations requiring a thorough safety review of the products before they hit store shelves. This chapter looks at the latest developments in nano-sized materials for use in cosmetics in an effort to address these problems despite the not-so-obvious hidden hazards.
