Zinc oxide is an inorganic compound with the formula ZnO. This is a white compound, which is non-soluble in water. ZnO nanoparticles are believed to be one of the three most produced nanomaterials, along with titanium dioxide nanoparticles and silicon dioxide nanoparticles. High thermal conductivity, anti-bacterial properties, humidifier, and high refractive index are the properties of ZnO. This material is biocompatible and safe and can be used easily in medicine and is widely used in cosmetic compounds because of the attraction of ultraviolet waves. This compound helps to eliminate bad smells and prevents bacterial growth, and it can well relieve any skin sensitivity.
