Non-Nano Zinc Oxide Powder – Reef-Safe Broad-Spectrum Mineral UV Filter

Craft superior environmental defense products with our Premium Non-Nano Zinc Oxide (ZnO) Powder. As a high-purity, inorganic mineral active, it is the premier choice for formulators creating “natural,” reef-safe, and sensitive-skin sunscreens. Because the particles are strictly non-nano (larger than 100 nm), they remain safely on the skin’s surface, creating a protective, non-penetrating film that shields the complexion from everyday environmental wear.

🌿 Key Aesthetic & Protective Benefits

• True Broad-Spectrum Shielding: One of the rare single mineral ingredients that offers comprehensive surface defense against both shortwave and longwave solar radiation (UVA and UVB).

• Exceptional Photostability: Unlike many synthetic alternatives, Non-Nano Zinc Oxide does not degrade under sunlight, ensuring long-lasting surface protection without requiring chemical stabilizers.

• Surface-Safe Non-Nano Profile: Particles sit entirely on top of the stratum corneum (the outermost skin layer) rather than absorbing into the skin, making it highly preferred for clean-beauty and eco-conscious brands.

• Delicate & Reactive Skin Comfort: Celebrated for its gentle, non-irritating, and non-comedogenic nature, making it the “gold standard” active for baby care, mineral makeup, and ultra-sensitive skin formulas.

• Reef-Safe Integrity: 100% mineral origin, meeting the strict environmental standards required for ocean-safe and reef-friendly labeling.

🧪 Technical Formulation & Usage

Non-Nano Zinc Oxide is a robust, white powder that acts as a physical barrier and requires thorough dispersion for optimal performance.

• Usage Rates: 5% – 25% (Depending on your target protection level).

• Mechanism: Works primarily by absorbing, reflecting, and scattering light waves right at the skin surface.

• Formulation Tip: To avoid a heavy “white cast” and ensure an ultra-smooth application, ensure thorough mechanical dispersion using a high-shear mixer or pre-disperse the powder in a compatible carrier oil (like Jojoba or CCT) before emulsification.

• Compatibility: Pairs exceptionally well with Titanium Dioxide for enhanced mineral synergy, as well as plant-based texturizers like Magnesium Stearate to improve water resistance.
