Non-nano zinc oxide is NOT one of those ingredients! Using sunscreen made with non-nano zinc oxide is the best way to ensure that you and your family stay safe in the sun without worrying about harsh chemicals absorbing into your skin or the ocean.
Most nanoparticle sunscreens in the marketplace have particle sizes of 15 nanometers or 0.015 micron. Micronized sunscreens are created by grinding larger particle sizes into smaller ones. Typically micronized particles are between 0.1 micron and 100 microns, however the grinding process may result in nanoparticles called ‘fines’ which are EWG’s Skin deep recommends zinc oxide 15-20% as an active ingredient in the sunscreen. Select 100% Non-Nano Particle Zinc Oxide. A sunscreen can be made with nano particles or non-nano particles. Nano particles are particles smaller than 100 nanometer and non-nano particles are particles bigger than 100 nanometer.
Background: Solar UV radiation (UVR) is composed of UVB (290-320 nm) and UVA (320-400 nm) wavelengths. Only two sunscreen active ingredients approved in the US, avobenzone (butylmethoxydibenzoylmethane) and zinc oxide (ZnO), provide true broad-spectrum protection against UVA wavelengths >360 nm.
Raw Elements. Raw elements makes several reef-safe, broad-spectrum SPF 30 non-nano zinc oxide sunscreens which include a tinted version. Their sunscreen sticks come in a compostable cardboard package and their sunscreen balm comes in a recyclable metal tin with a paper sticker for product labeling. They make sunscreens for babies or kids and
what is non-nano zinc oxide used for? Non-nano zinc oxide is an active ingredient used in mineral sunscreens to provide broad-spectrum coverage against both UVA and UVB rays. Non-nano guarantees you’ll enjoy all the benefits of zinc oxide in the safest and most effective way possible.
