The main purpose of toothpaste is to remove the dirt adhered to the teeth and damage the gums. This requires a neutral friction agent. However, aluminum hydroxide has the characteristics of mild friction to clean and polish teeth, which just meets this requirement. And its chemical inertness makes it compatible with other ingredients in toothpaste. Moreover, aluminum hydroxide has good fluorine retention performance. Therefore, aluminum hydroxide is widely used in drug toothpastes and other high-grade toothpastes.

The particle size of aluminum hydroxide used for toothpaste is generally 7 microns, which is a grinding product produced by air flow mill or rod mill.
Its attached alkali must be less than 0.01%, or keep a certain pH value to prevent the toothpaste skin from corrosion during storage.
