Overview of White Carbon Black for Toothpaste White carbon black, also known as silicon dioxide (SiO2), plays an important role in toothpaste. It is mainly prepared by precipitation method and has the characteristics of large surface area, strong adsorption capacity, stable properties, non-toxic and harmless. These characteristics make white carbon black an indispensable raw material in toothpaste.

Types and characteristics of white carbon black used in toothpaste
White carbon black for toothpaste can be divided into three types of products based on its use and characteristics: friction type, mixed type, and thickening type. These different types of white carbon black play different roles in toothpaste:

Friction type white carbon black: It has a large particle size and strong friction, which can effectively remove stains and plaque on the surface of teeth. Meanwhile, due to its soft abrasive properties, it will not damage dental enamel.
Mixed type white carbon black: Combining the characteristics of friction type and thickening type white carbon black, it not only has a certain degree of friction, but also provides good thixotropy and stability.
Thickened white carbon black: mainly used to increase the viscosity of toothpaste, making the paste more stable. It can suspend heavier abrasives and polishing particles, preventing the separation of solid-liquid components in toothpaste.
Production process of white carbon black for toothpaste
The production process of white carbon black for toothpaste mainly includes steps such as precipitation reaction of sodium silicate and sulfuric acid, vacuum filtration, drying, and airflow crushing. By controlling reaction conditions such as feeding sequence, proportion, process temperature, etc., white carbon black products with different structures and properties can be prepared. These products can meet the needs of different toothpaste varieties, such as transparent toothpaste, semi transparent toothpaste, etc.

The application advantages of white carbon black for toothpaste
Improving the transparency of toothpaste: The refractive index of white carbon black is very close to that of other ingredients in toothpaste, making the toothpaste paste present a good transparent state.
Reduce friction: White carbon black, as a soft abrasive, can remove tooth stains while reducing damage to enamel.
Good compatibility: White carbon black has good compatibility with fluoride and other raw materials in toothpaste, which can ensure the stability and effectiveness of toothpaste.
Thickening effect: White carbon black can provide excellent thickening effect, making toothpaste paste more stable, easy to use and store.
Market prospects of white carbon black for toothpaste
With the increasing demand for oral care products, the toothpaste market is showing a diversified development trend. As an important raw material in toothpaste, the market demand for white carbon black is constantly increasing. In the future, with the continuous advancement of technology and the expansion of applications, the application of white carbon black in toothpaste will be more extensive and in-depth.

In summary, white carbon black used in toothpaste plays an increasingly important role in the toothpaste industry due to its unique properties and wide application prospects. In the future, with the continuous advancement of technology and the continuous development of the market, the application of white carbon black in toothpaste will become more diversified and efficient.
