Colloidal Silica: A Fine Excipient in the Food and Pharmaceutical Fields
Colloidal silica, a type of food and pharmaceutical grade excipient, possesses unique colloidal properties and an ultra-large specific surface area. Its particles have a small and uniform diameter, and the surface is rich in hydroxyl groups, which endows it with excellent adsorption and dispersion properties.

In the pharmaceutical field, it serves as a high-quality drug carrier. Relying on its excellent adsorption capacity, it can adsorb active pharmaceutical ingredients, control the drug release rate, and improve the bioavailability of drugs. It plays a particularly important role in the research and development of sustained-release and controlled-release preparations. Additionally, it can be used as a stabilizer for suspensions, preventing particle sedimentation in the liquid medicine and ensuring the uniformity and stability of the liquid medicine. In the food industry, it can act as a clarifying agent in the processing of foods such as fruit juices and alcoholic beverages. It adsorbs impurities in them, improves the clarity and quality of food, and does not affect the flavor of food.
