Special Silica for Toothpaste

  Hydrated Silica In Toothpaste HPSIL® Speciality Silica for toothpaste is an amorphous powder, odorless, insoluble in water or acid, chemically inert, and has good compatibility with fluoride and other raw materials in toothpaste. The structure and particle size of silica can be controlled by production conditions. According to the different types of toothpaste, three kinds of products are produced: friction, mixed and thickening.
