Zinc Oxide

Zinc oxide is a kind of inorganic substance, chemical formula is ZnO, commonly known as zinc white, is a kind of zinc oxide. Insoluble in water, soluble in acids and strong bases. Zinc oxide is a common chemical additive, widely used in plastics, silicate products, synthetic rubber, lubricating oil, paint coatings, ointments, adhesives, food, batteries, flame retardants and other products in the production. Zinc oxide has a large band gap and exciton binding energy, high transparency, excellent room temperature luminous performance, in the semiconductor field of liquid crystal display, thin film transistors, light-emitting diodes and other products are used. In addition, micro-particles of zinc oxide as a nanomaterial also began to play a role in related fields.

Zinc oxide is an important and widely used physical sunscreen that blocks UV rays by absorption and scattering. Nano zinc oxide is a stable compound that provides a broad spectrum of UV protection (UVA and UVB), as well as antibacterial and anti-inflammatory effects, making it the safest and most effective ingredient in almost all countries' evaluations of sunscreens.
