 Nanotechnology is a science that manipulates atoms and molecules at the nanoscale with a global market of 00 billion by 2015. It has applications in cosmetics due to enhanced properties such as colour, transparency and solubility. Types of nanomaterials used include nanosomes, liposomes, fullerines and solid lipid nanoparticles. However, concerns over safety have led to regulations limiting their use and enforcing safety assessments before they enter the market. This review focuses on the types of nanomaterials used by cosmetic brands, potential risks to human life and the environment and possible regulations to address these concerns.
