Application

Hydrated silica in toothpaste TP 48 has thickning function in tooth paste

A large amount of water absorption can reduce the amount of other grinding capacity and provide a higher viscosity.

Usage method : In the toothpaste formula, it is used alone at the dosage of 3-8%

The toothpaste's main functions are:

  1. Providing the right texture without feeling greasy and good flow.
  2. Staying on the toothbrush without collapsing for effective brushing.
  3. Easily spreading during brushing for good coverage.
  4. Remaining stable during storage without separating or degrading.
  5. Having an exquisite and glossy appearance with even abrasives.
  6. Being highly compatible with other toothpaste components, especially active ingredients.
