The formula of toothpaste is related to the effect of cleaning teeth and protecting gums. Its ingredients are complex, and it is a fusion of chemical delicacies.

The main ingredients are friction agents, such as calcium carbonate, calcium hydrogen phosphate, etc. Its texture is delicate, which helps remove tartar stains when brushing teeth, and does not hurt the tooth glaze. The calcium carbonate, with the chemical formula of CaCO
, is white powder, stable in nature, and plays an important cleaning role in the toothpaste system; calcium hydrogen phosphate, with the chemical formula CaHPO
, can provide moderate friction and achieve a balance between cleaning and dental care.

In addition, it is a humectant, mostly glycerin and sorbitol. For glycerol, the chemical formula C < unk > H < unk > O < unk > has strong water absorption, which can prevent the toothpaste from drying out, maintain its soft paste state, and facilitate extrusion use. Sorbitol, the chemical formula C < unk > H < unk > O < unk >, also has good moisturizing power, and the taste is suitable, which does not affect the user's experience.

Surfactant is also indispensable, and sodium lauryl sulfate is commonly used. Its chemical formula C < unk > H < unk > SO < unk > Na can reduce the surface tension of the liquid, make the toothpaste rich in foam, and help disperse dirt and enhance the cleaning effect.

In addition, there are preservatives to maintain the quality of toothpaste, such as parabens; thickeners to determine the form of toothpaste, such as sodium carboxymethyl cellulose; and flavors, sweeteners, etc., to adjust its taste and smell, making the brushing experience better. The delicate formula of toothpaste is the perfect combination of chemistry and life, escorting oral health.
