The application of silica in toothpaste has a history of more than 20 years. As early as 1978, Chengdu Toothpaste Factory used silica to produce the first silica toothpaste "Effective Multi" in China. However, due to the low consumption level and health awareness at that time, this new type of abrasive was not widely used in the country. With the improvement of production level, people gradually realized the importance of silica in improving the quality of toothpaste and protecting teeth. In the formula of toothpaste, the main raw material affecting the stability of fluoride is abrasive, and silica has good chemical stability and good compatibility with fluoride.

In addition, silica is generally divided into high structure and low structure. The actual production process is divided according to the water content of the filter cake, that is, the wet cake moisture. Wet cake moisture above 70% is a high structure product, that is, a thickening type, and below 70% is a low structure product, that is, a friction type. Among them, abrasive silica has excellent dispersing and suspending properties, its particles are compact and have strong friction. The toothpaste made with it as an abrasive has a delicate paste, a smooth taste, good paste stability, and does not damage teeth. It has a satisfactory effect on improving the organizational structure and appearance of the paste. Thickening silica has good compatibility, extremely fine particle size, and excellent hydration strength. Its structural characteristics make it suitable for toothpaste.
