Silica Abrasive Felcosil-TP 28 for High Brasive in Toothpaste Formulations
Silica Abrasive in tooth paste
Chemical Properties
silica in tooth paste Felcosil-TP 28 is a synthetic silica with superior abrasive power and compatibility with other ingredients
It is a silica material specifically designed for toothpaste formulations, mainly used to enhance the cleaning effect of toothpaste and improve its physical properties. Compared with ordinary white carbon black, the particle morphology and physical properties of wear-resistant white carbon black have been specially designed to effectively remove stains and plaque on the surface of teeth while cleaning them, without causing excessive wear on teeth.
