Our Nano Zinc oxide is used in a wide range of cosmetics and personal care products including makeup, baby lotions, bath soaps and foot powders.
It is used as a bulking agent, a colorant, a skin protectant in over-the-counter (OTC) drug products and as a sunscreen.
When used in sunscreen products, ZnO acts as a physical block to the sun's ultraviolet (UV) radiation, helping to reduce or prevent sunburn and premature aging of the skin.
Preventing sunburn is an important factor in reducing skin cancer risk.
Zinc oxide is the broadest spectrum UVA and UVB reflector approved for use as a sunscreen by the FDA and is allowed in concentrations up to 25%.
