Application of white powder of zinc oxide in medicine and health

l White powder of zinc oxide has deodorizing and antibacterial functions, so it is added to cotton fabric, rubber, food packaging, etc.

l White powder of zinc oxide added in food not only has a certain antiseptic effect, but also an important zinc source for the human body to supplement zinc;

l White powder of zinc oxide is used to improve skin health, such as baby powder, diaper rash ointment, zinc cream, anti-dandruff shampoo and antiseptic.

l White powder of zinc oxide mixed with about 0.5% iron oxide is called calamine, which is used to make calamine lotion for the treatment of acute itchy skin diseases. Zinc oxide is incorporated into sports bandages to prevent soft tissue damage during sports.

l White powder of zinc oxide has a very strong ability to absorb ultraviolet rays with a wavelength of 280-400nm, so it is often used in various sunscreen products to prevent sunburn and other skin diseases caused by ultraviolet rays.

l Clove oil and zinc oxide cement made from white powder of zinc oxide can be used as filling materials or cavity sealing materials.
