A line of zinc oxide products calledZ-COTE® lets manufacturers put their own spin on formulations with choices like coated, uncoated, nano and non-nano, as well as powders and a dispersion option. So, let’s talk about why zinc oxide is such a trusted ingredient with consumers.
While Zinc Oxide is largely considered safe for topical applications, there are some considerations to keep in mind. Ensuring non-nano forms of Zinc Oxide and proper formulation can mitigate potential risks. Zinc Oxide Uses Skin Protection. Zinc oxide is extensively used in skin protection applications.

The oral exposure to ZnO nanoparticles as cosmetic ingredient in sunscreens is limited to accidental ingestion of small fractions of lip products and sun protection products and can be considered to be low. Upon inhalation of ZnO nanoparticles, serious local effects in the lung were observed.
Non-nano zinc oxide particles are too large to penetrate, or be absorbed through the skin, making it a very effective natural sunblock ingredient. Ocean Friendly Non-nano zinc oxide is used in reef-safe sunscreen products.

This reef-safe, non-nano zinc oxide formula contains turmeric and a proprietary probiotic that supports healthy, clear skin. Get Kinship Self Reflect Probiotic Moisturizing Sunscreen Zinc Oxide SPF 32 for $42.

The range for "non-nano" is 100 nanometers (nm) or greater, while "nano" zinc oxide (used because it is non-whitening) is typically 10-20 nm in size. To give you a sense of how small that is, one nanometer is a billionth of a meter. The terms "nano" and "micronised" both refer to the size of the Zinc Oxide particles used in your sunscreen. Thanks to modern improvements in formulating mineral sunscreens, Zinc Oxide has become available in a ‘micronised’ form, meaning it is clear on application, lightweight and non-greasy. fVA3f.
