What are the ingredients in toothpaste and what are their functions? I hope to answer comprehensively.

In the previous toothpaste mixing, because there were many water-containing sodium silicate as filler and binder, the toothpaste had a bitter taste, which was easy to cure after a long time. Its diffusivity and stability are not good. In order to change the bitter feeling, it is often necessary to add more additives such as saccharin and ethanol. However, if the dosage is too much, it will also produce a strange smell and cannot be stored for a long time. In view of the above problems, amorphous silicic acid with an average particle size of 30 ~ 100 m was produced by wet method, which obviously improved the quality of toothpaste. The optimum particle size is 40 ~ 80μ m, which has poor sense of use and stability. When it is larger than 100 μm, it feels rough and is harmful to teeth. If the average agglomerated particle size of hydrated silicic acid is 5 ~ 20μ m, the optimum range is 10 ~ 15μ m, and the liquid absorption per gram is 0.0 ~ 1.5 cc, the toothpaste component with good diffusibility can be obtained. The amount of silicic acid is 1 ~ 20% of the total amount, preferably 5 ~ 15%. When it is used in combination with calcium abrasive, the diffusivity is poor when the dosage is less than 1%, and it has a special taste when it is more than 20%. The calcium abrasives used in this patent include calcium diphosphate, calcium triphosphate, calcium carbonate, calcium pyrophosphate, etc. The commonly used calcium phosphate is in the range of 20 ~ 50, and the total amount of calcium abrasive and anhydrous silicic acid should be below 50%, so that toothpaste has good diffusibility. The components used as adhesive are: hexamethylcellulose, carrageenan, alginic acid, propylene glycol alginate, hydroxyethyl cellulose, etc. The dosage is 0.3 ~ 10%. The humectant includes glycerol, sorbitol, propylene glycol, polyvinyl alcohol, etc. , the dosage is 15 ~ 35%. Generally, it is required that the boiling point of chemicals used as spices is in the range of 50 ~ 150℃ under normal pressure. These compounds include: methyl acetate, n-propyl acetate, methyl propionate, ethyl propionate, propanol, butanol, methyl ethyl ketone, tert-butyl methyl ketone, acetaldehyde, butyraldehyde and other organic Chinese compounds, which can be used in combination of one or more. The dosage is 0.02 ~ 0.5%. In addition, a certain amount of anionic surfactants, foaming agents, water, sweeteners, some anti-insect dentifrices and fungicides should be added. As preventive agents for dental diseases, there are fluorides such as sodium fluorophosphate, stannous fluoride and sodium fluoride, dihydrocholesterol and diaryl acetate. Toothpaste made from the above ingredients has strong decontamination ability, rapid diffusion of spices and other ingredients, no astringency, good stability and convenient long-term storage.
