CHAPTER 7: Nanoparticle Safety in Cosmetics Check Access

Nanoparticles have occupied a significant role in a wide spectrum of applications around us. Their prevalence is attributed to the fact that nanoparticles exhibit many novel properties compared with bulk materials. However, this promising technology often raises societal concerns about human safety during and after exposure. This chapter aims to provide insights into the health risks of nanoparticle exposure. Due to the growing market of cosmetics, this review also highlights the common nanoparticles or nanomaterials used and their toxicity studies. Yet, the toxicity of the nanoparticles and nanomaterials remains debatable. More investigations need to be done in order to come up with a universally accepted conclusion. Although safety regulations are put in place to protect the well-being of consumers, workers and the environment, limitations still exist.
