Zinc oxide is an inorganic compound with the formula ZnO. It is a white powder that is insoluble in water. Crystalline zinc oxide is thermochromic, changing from white to yellow when heated in air and reverting to white on cooling.
Zinc oxide is a largely inert, white compound which is used very widely as a bulking agent or filler, and as a white pigment. It is found in some rubber, glass and ceramic products, and finds use in the chemical industry as a catalyst. It is also used in paints as a corrosion inhibitor and for mildew control.
Zinc is an essential trace element, and zinc oxide is added to fertilizers, animal feed, and vitamin supplements. It is also used in a many cosmetic and medical products and in toiletries. Zinc oxide also has antibacterial and deodorizing peroperties. For this reason it is employed in medical applications such as in baby powder and creams to treat conditions such as diaper rash, other skin irritations and even dandruff. Due to its reflective properties it is also used in sunblocks and can often be seen on the nose and lips of lifeguards at the beach. It is found in, for example, baby powder and anti-dandruff shampoos, in calamine lotion and in sticking plasters and dental cement.
It is used in a wide range of cosmetics and personal care products including makeup, nail products, baby lotions, bath soaps and foot powders. Zinc oxide is also used in skin protectants, such as diaper rash ointments and sunscreen products.
Its strong absorption of ultra-violet (UV) light has led to its use in sunscreen lotions. It blocks both UVA (longer wavelength) and UVB (shorter wavelength) radiation, protecting against sunburn, skin damage and cancer.<\/p>\n
