Application
Hydrated silica in toothpaste TP 48 is used in transparent and translucent high-grade toothpastes. 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:
- Providing the right texture without feeling greasy and good flow.
- Staying on the toothbrush without collapsing for effective brushing.
- Easily spreading during brushing for good coverage.
- Remaining stable during storage without separating or degrading.
- Having an exquisite and glossy appearance with even abrasives.
- Being highly compatible with other toothpaste components, especially active ingredients.
