Types of Zinc Oxide

Zinc oxide (ZnO) is a metal oxide used in mineral sunscreens to provide broad-spectrum protection against UV radiation.
ZnO nanoparticles (ZnO-NP) are used in some sunscreens, offering improved transparency and cosmetic elegance. The average size of ZnO nanoparticles, as measured by TEM, is a key factor influencing their transparency and performance in sunscreen formulations. ZnO nanoparticles transmit and scatter the visible part of solar radiation, resulting in a more transparent appearance on the skin compared to larger particles.
Coated zinc oxide, such as FLYCHEM’s Zincaptis™ (Micronised Zinc Oxide / Lipid Coated), provides enhanced stability and safety, reducing the risk of skin irritation. The type of coating applied to ZnO nanoparticles can significantly influence their penetration into skin layers and overall safety profile. Additionally, the interaction of zinc oxide compounds with the skin is affected by both the nanoparticles’ coating and their underlying chemistry.
Uncoated zinc oxide is also effective, but may have a higher risk of skin irritation and instability.
Titanium dioxide is another common ingredient in mineral sunscreens, often used in combination with zinc oxide.

Mechanism of Action of Lipid-Coated Micronised Zinc Oxide

Lipid-coated micronised zinc oxide is a cutting-edge mineral sunscreen ingredient designed to deliver superior sun protection while being gentle on the skin. With an average size of around 200 nanometers, these zinc oxide particles are coated with a layer of lipids, which helps them disperse evenly in sunscreen formulations and enhances their stability. When applied, the particles remain on the skin’s surface, forming a physical barrier that effectively scatters and reflects both UVA and UVB rays.

This broad-spectrum protection helps shield the skin from sunburn, premature skin aging, and the risk of skin cancer. The lipid coating not only enhances the texture and feel of the sunscreen, making it lightweight and less likely to leave a white cast, but also reduces the potential for irritation, making it ideal for sensitive skin, acne-prone skin, and combination skin types. By providing a gentle yet powerful defense against the sun's harmful rays, lipid-coated micronized zinc oxide is a standout active ingredient in modern mineral sunscreens.
