March 3, 2025, Beijing - Stanford University scientists have revealed potential health risks associated with amorphous silica in their latest research. For a long time, amorphous silica has been widely used in food, medicine, and cosmetics, and is considered an inert and safe substance. However, the latest research has found that amorphous silica may damage cellular components after undergoing redox reactions with biomolecules containing thiol compounds in the human body.

Although it cannot be concluded at present that amorphous silica poses a direct threat to health, scientists remind caution when using silica particles. Especially in the food industry, unnecessary chemicals should be avoided as much as possible. This discovery has sparked widespread attention within the industry, and in the future, the use and regulation of silica may become even stricter.
