Precipitated silica has many special functions in daily chemical products, which are mainly due to its unique physical and chemical properties, such as porosity, high specific surface area, good dispersibility and thickening. The following is a detailed summary of its special functions in daily chemical products:

1. Toothpaste
Abrasives and thickeners: Precipitated silica is often used as an abrasive and thickener for toothpaste. It has a large surface area and strong adsorption capacity, which can effectively remove stains on the surface of teeth without causing excessive wear to the teeth. In addition, it can also improve the consistency and stability of toothpaste, making the toothpaste more uniform and delicate during use.
Improve transparency and aesthetics: Precipitated silica can improve the transparency of toothpaste, make the toothpaste look more crystal clear, and enhance the aesthetics of the product.
Drug stability: In drug toothpaste, precipitated silica helps to maintain the stability of drug ingredients and avoid drug failure during storage and use.

2. Cosmetics
Fillers and thickeners: In cosmetics such as lipsticks and nail polishes, precipitated silica can be used as a filler and thickener to improve the consistency and stability of the product, while giving the product a better touch and appearance.
Sunscreen and anti-aging: Due to its strong ability to reflect ultraviolet rays and good stability, precipitated silica can also be used as a sunscreen ingredient in cosmetics to help resist ultraviolet damage to the skin and slow down skin aging.
Concealer and whitening: In products such as foundation and concealer, precipitated silica can provide better concealer effects, making the skin look whiter and more even.

3. Other daily chemical products
Anti-caking agent: In products such as washing powder, detergent, and soap, precipitated silica can be used as an anti-caking agent to prevent the product from caking during use and improve the product's use effect.
Preservative: In packaging materials such as food packaging bags, precipitated silica can be used as a preservative to extend the shelf life of food.
Improved thixotropy and fluidity: In a variety of daily chemical products, precipitated silica can improve the thixotropy and fluidity of the product, making the product smoother and easier to apply when used.

The special functions of precipitated silica in daily chemical products are mainly reflected in its application as a friction agent, thickener, filler, sunscreen, anti-caking agent, etc. These functions not only improve the performance and quality of daily chemical products, but also meet consumers' needs for product aesthetics, safety and use effects. At the same time, with the advancement of science and technology and the continuous improvement of technology, the application prospects of precipitated silica in daily chemical products will be broader.
