What toothpaste is less salty

The main ingredient of toothpaste.

Toothpaste is made up of powdered friction agents, wetting agents, surfactants, binders, flavors, sweeteners and other special ingredients.

1. Friction agent.

Friction agents commonly used in toothpaste are:

Calcium carbonate (CaCO3): There are two kinds of calcium carbonate: heavy and light, heavy calcium carbonate is made by crushing, grinding and refining limestone and calcite in rocks. Light calcium carbonate is to dissolve calcium salt in hydrochloric acid, and then introduce carbon dioxide to obtain calcium carbonate precipitation.

Light calcium carbonate has fine particles and light specific gravity, so it can be used in toothpaste.

Dicalcium phosphate (dicalcium phosphate dihydrate Cahpo4?2H2O and dicalcium phosphate anhydrous salt CahPO4): Dicalcium phosphate is divided into two types: dihydrate salt and anhydrous salt of dimolecular water.

Salt dihydrate has good mixing with other ingredients, but due to the high hardness and strong friction of anhydrous salt, 5 10 anhydrous salt can be mixed into the special toothpaste to remove smoke marks.

Calcium pyrophosphate (Ca2P2O7): Calcium pyrophosphate is obtained by treating calcium diphosphate at high temperature. Since it does not react with fluorinated compounds, it can be used as a base for fluoride toothpaste.

Hydrated silicic acid (SiO2?NH2O): Hydrated silicic acid is a very fine white particle that can be used in clear toothpaste. In addition, due to its large specific volume, it can be used as an extender and tackifier for toothpaste.

Aluminum hydroxide [A1(OH)3]: The particles of aluminum hydroxide are coarse, but it will not damage the enamel, and can increase the brightness of the toothpaste, and has excellent tooth cleaning power.

2. Wetting agent.

The wetting agent prevents the toothpaste from curing and hardening in the hose and gives the paste its gloss, among other things. The wetting agents used in toothpaste include glycerin, propylene glycol, sorbitol and so on.

3. Surfactant.

In order to clean the dirt in the mouth, a neutral detergent - sodium lauryl sulfonate is widely used. It foams quickly, foaming and cleansing dirt from the mouth. The purity of the surfactant used in toothpaste is very high, and there can be no peculiar smell, and the general dosage is 2

4. Adhesive.

In order to evenly disperse the ingredients in toothpaste, binders such as CMC (carboxymethylcellulose sodium salt) and its derivatives, carrageenan, sodium alginate and other substances can be used.

Look at the tail of the toothpaste, not a black vertical bar.

You can't pick a toothpaste based on the taste, it depends on the problems with your teeth and the ingredients of your toothpaste.

1 fluoride toothpaste:

It is a toothpaste that adds an appropriate amount of fluoride to toothpaste and has the function of preventing tooth decay. Numerous studies have proven that fluoride can improve the resistance of teeth to corrosion and inhibit the growth and reproduction of cariogenic bacteria. Normal oral ring.

There is also a certain amount of fluorine in the environment, but its concentration is not enough to cause the above changes. The use of fluoride toothpaste is to increase the local fluoride in the oral cavity within a safe range to form a strong protective layer on the tooth surface, thereby reducing the occurrence of tooth decay.

Bear. Reminder: Children under 3 years of age should avoid fluoride toothpaste due to the presence of toothpaste swallowing in children; Children aged 4-6 years old should use it under the guidance of adults, and the amount of each brushing should be the size of a soybean grain.

2 Chinese herbal toothpaste:

It is a drug that adds some Chinese herbs on the basis of ordinary toothpaste, which has the effects of clearing heat and detoxifying, reducing inflammation and stopping bleeding, which can have a certain auxiliary effect on relieving the inflammation of the gums.

3 Anti-inflammatory toothpaste:

On the basis of ordinary toothpaste, certain antibacterial drugs are added to reduce inflammation and antibacterial, inhibit the formation of dental calculus and plaque, and play a role in improving the oral environment, preventing and assisting ** gum bleeding and periodontal disease.

4. Hypoallergenic toothpaste:

This toothpaste contains desensitizing ingredients such as potassium nitrate or strontium chloride, which has a certain relieving effect on dentin allergies.

5. Detergent and whitening toothpaste:

This type of toothpaste contains drugs such as peroxide or hydroxyapatite, which uses the principle of friction and chemical bleaching to remove the coloration of the tooth surface and play a role in whitening the teeth.

Salty is good, it contains sodium chloride. It can whiten teeth
