Zinc oxide (ZnO) has a wide range of commercial applications due to its unique properties. Some common commercial uses of zinc oxide include:


Zinc oxide is a key ingredient in many sunscreens due to its ability to block both UVA and UVB rays. It acts as a physical sunscreen by reflecting and scattering UV radiation away from the skin.


Zinc oxide is used in various cosmetic products such as foundations, powders, lip balms, and creams due to its UV-blocking properties and its ability to soothe and protect the skin.

Plastics and Polymers

Zinc oxide is added to plastics and polymers to enhance their resistance to ultraviolet (UV) radiation. This helps prevent degradation of the material when exposed to sunlight, thereby extending the lifespan of plastic products used outdoors. 

Zinc oxide nanoparticles can impart antibacterial properties to plastics and polymers, making them suitable for applications where bacterial growth needs to be controlled, such as in medical devices, food packaging, and household products.

Paints and Coatings

Zinc oxide is added to paints and coatings as a pigment and to impart various properties such as durability, corrosion resistance, and UV protection.

Rubber Manufacturing

Zinc oxide is utilized as an activator in the vulcanization process of rubber, enhancing the properties of rubber compounds such as tensile strength, elasticity, and resistance to heat and aging.


In the ceramics industry, zinc oxide is employed as a fluxing agent, helping to lower the melting point of ceramic materials and promoting uniformity during firing processes.


Zinc oxide nanoparticles are incorporated into textiles to impart antimicrobial properties, providing protection against bacteria and fungi, thus extending the lifespan of textiles and improving hygiene in various applications such as clothing, medical textiles, and household textiles.

These are just a few examples of the many commercial uses of zinc oxide across various industries. Its versatility and beneficial properties make it a valuable material in numerous applications.
