I. Mechanism of colloidal silica
Colloidal silicon dioxide is a highly active inorganic colloidal materials, due to its microporous structure, special surface properties and dispersion properties in different media, so it has a wide range of applications in many fields.
1.Thickener
Colloidal silicon dioxide is an excellent thickener, can increase the viscosity and concentration of the fluid, so as to achieve the purpose of controlling the rheological properties and improving the quality of products. In food, cosmetics, pharmaceuticals and other fields, colloidal silicon dioxide is often used as a stabiliser, thickener, emulsifier and so on.
2.Antiseptic
Colloidal silicon dioxide can also be used as a preservative, which can prevent the growth and reproduction of microorganisms and bacteria to extend the shelf life of the product. Colloidal silica is widely used as a preservative in food, medicine and other fields.
3.Carrier
Colloidal silica is an excellent carrier material in which drugs and other chemicals can be encapsulated and their release slowed down for better efficacy and safety. In pharmaceuticals and cosmetics, colloidal silicon dioxide is a commonly used carrier material.
Second, the application of colloidal silicon dioxide
1.Food industry
Colloidal silicon dioxide has a wide range of applications in the food industry, can be used as vegetable oils, lipids, dairy products, such as stabilizers, emulsifiers, anti-caking agents, preservatives. In addition, colloidal silicon dioxide can also be used in some beverages as a suspension and thickening agent.
2. Pharmaceutical industry
Colloidal silicon dioxide in the drug industry also has a wide range of applications, can be used as a carrier, dispersant, adsorbent and so on. For example, silicon film, capsules and other products contain colloidal silicon dioxide.
3. Cosmetic industry
Colloidal silicon dioxide in the cosmetics industry can be used as a thickener, emulsifier, stabiliser, etc., can be used in lotions, sunscreen, shower gel and other products.
In short, colloidal silicon dioxide is a very practical material with a wide range of application prospects. In different fields, people can apply colloidal silicon dioxide in the research and development and manufacture of products according to its characteristics and mechanism of action, in order to improve product quality and performance.
