Synthesized under high-temperature, high-pressure solvothermal supercritical conditions. It offers better dispersibility (uniform, stable), good compatibility with other materials, and jade-like silica reduces ZnO’s alkaline irritation for gentleness. It resists yellowing, boosts UV resistance/antibacterial properties (heavy metal-free for cosmetics), enhances coating UV/infrared absorption, and improves product strength for coatings/rubber/plastics. Also works as a photocatalyst and antibacterial agent for eco-coatings, fibers, batteries, and masks.
20-30nm silica-coated zinc oxide with jade-like properties for cosmetic UV protection and antibacterial applications.
