Composition of Toothpastes
A typical toothpaste contains a range of ingredients shownin Table 1. The abrasive, such as calcium carbonate or hydrated silica, is responsible for removing the debris and discoloration from the teeth. Detergent surfactants, such as sodium lauryl sulfate, lower the surfact tension and therefore help loosen plaque deposits and emulsify or suspend the debris removed from the tooth surface during cleaning. Surfactants also contribute to the foaming property of toothpastes.
