Question 1: How is toothpaste made? Toothpaste is composed of powder friction agent, wetting agent, surfactant, adhesive, perfume, sweetener and other special ingredients. 1. The commonly used friction agents in toothpaste are: ① calcium carbonate (CaCO3): there are two kinds of heavy calcium carbonate and light calcium carbonate. Heavy calcium carbonate is made by crushing, grinding and refining limestone and calcite in rocks. Light calcium carbonate is obtained by dissolving calcium salt in hydrochloric acid and then introducing carbon dioxide. Light calcium carbonate has fine particles and light specific gravity, and can be used in toothpaste. ② calcium hydrogen phosphate (calcium hydrogen phosphate dihydrate CaHPO4? 2H2O and anhydrous calcium hydrogen phosphate (CaHPO4): Calcium hydrogen phosphate can be divided into dihydrate salt and anhydrous salt of bimolecular water. The dihydrate salt has good miscibility with other ingredients, but due to the high hardness and strong friction of anhydrous salt, 5% ~ 10% anhydrous salt can be mixed into the dihydrate salt in the special toothpaste for removing smoke marks. ③ Calcium pyrophosphate (Ca2P2O7): Calcium pyrophosphate is obtained by high-temperature treatment of calcium hydrogen phosphate. Because it does not react with fluoride, it can be used as the base material of fluoride toothpaste. ④ Hydrated silicic acid (SiO2? NH2O): Hydrated silicic acid is a very fine white particle, which can be used in transparent toothpaste. In addition, because of its large specific volume, it can be used as a filler and tackifier for toothpaste. ⑤ Aluminum hydroxide [A 1(OH)3]: Aluminum hydroxide particles are coarse, but it will not damage the enamel, and can increase the brightness of toothpaste, which has excellent cleaning power. 2. Wetting agent Wetting agent can prevent toothpaste from curing and hardening in the hose, so that the paste has luster and other effects. Wetting agents used in toothpaste include glycerol, propylene glycol and sorbitol. 3. Surfactants are used to clean dirt in the mouth. At present, sodium dodecyl sulfate is widely used as a neutral detergent. Can quickly foam, not only can foam, but also can clean the dirt in the mouth. The surfactant used for toothpaste requires high purity and no peculiar smell, and the general dosage is 2%. 4. Adhesives In order to uniformly disperse the ingredients in toothpaste, adhesives can be used, such as cMc (sodium carboxymethyl cellulose) and its derivatives, carrageenan, sodium alginate and other substances. 5. The spice used in spice toothpaste is mainly mint, which is an indispensable ingredient to give toothpaste a cool feeling. Mint is divided into menthol, peppermint oil, peppermint and other substances, as well as spices derived from them. In addition, fruit flavors, such as citrus flavors, can also be used, but there are strict restrictions as toothpaste flavors. 6. Sweetener In order to improve the taste of toothpaste, a small amount of saccharin was added to the toothpaste. Glycerol as a wetting agent also has a sweet taste, so the dosage of saccharin is generally 0.0 1% ~ 0. 1%. Xylitol can also be used as a sweetener. 7. Other special ingredients In order to prevent and treat oral diseases, some special ingredients are added to some toothpastes: ① In order to remove bad breath, fungicides such as dioxane and cedrol are often added to toothpaste, and copper chlorophyllin also plays a certain role in preventing bad breath. ② Fluoride can be added to prevent dental caries, which can not only inhibit the fermentation of oral residues, but also strengthen the enamel on the tooth surface. Considering the safety, the fluorine content in toothpaste is below 1000 micrograms. People who use fluorine-containing natural water have a relatively low incidence of dental caries, but drinking water with high fluorine content will form white turbidity (mottled teeth) on the tooth surface and make the teeth brittle.

Question 2: What is the principle of toothpaste? What is matter and what is the shell made of? The largest proportion of toothpaste ingredients are abrasives, such as calcium carbonate, dolomite, aluminum hydroxide, silicon dioxide, calcium hydrogen phosphate and so on. And wetting agents (glycerol, sorbitol, propylene glycol, polyethylene glycol, etc. ), adhesives, foaming agents, sweeteners (such as saccharin and stevioside). ) and spices (menthol). According to its own unique formula, medicinal toothpaste is added with various drugs, such as Chinese herbal medicine, western medicine, fluoride, enzyme, chlorophyll and various antibacterial agents. In order to achieve the effects of anti-inflammation, sterilization, caries prevention, acid prevention, desensitization and tartar prevention.

The physical function of toothpaste is friction and adsorption: the powdered abrasive in toothpaste can mechanically brush off the attachments on the tooth surface and between teeth, such as food residues, dental plaque and tartar, which can clean and whiten teeth, remove tartar and prevent dental calculus, strengthen teeth and enhance the ability to resist acidic substances.

The chemical function of toothpaste is foaming and washing: the surfactant in toothpaste is used to foam and emulsify during brushing to absorb the dirt in teeth and mouth; Dissolve, decompose and neutralize dental plaque and adhesion, so as to achieve the purpose of cleaning teeth and oral health care.

The biological functions of toothpaste are bacteriostasis, antibiosis and deodorization. There are many bacteria in the mouth, and many bacteria are harmful to dental health and oral health care. Effective ingredients in toothpaste, such as surfactants and added drugs, can inhibit the growth of bacteria in the mouth, and even directly sterilize, thus effectively ensuring the health of teeth. In addition, the spices in toothpaste can not only sterilize, but also get rid of bad breath, and at the same time satisfy all the sensory functions that can be felt in the mouth (taste, smell and mouth), so that the mouth has a refreshing and refreshing feeling.

Question 3: What is the material of toothpaste? It is best to tell the manufacturing process. Supplement: The latest toothpaste material pvc aluminum-plastic composite hose is plastic. You have to ask someone about the old polyethylene, but now it seems to be pep. ..

Question 4: What is toothpaste made of as abrasive, cleaning agent, wetting agent, preservative and fragrance?

Question 5: Toothpaste formula Excuse me, what is toothpaste made of PVC and polyethylene?

Question 7: What is toothpaste made of? Toothpaste with special materials is a complex mixture, which usually consists of abrasives (such as calcium carbonate and calcium hydrogen phosphate), humectants (such as xylitol and polyethylene glycol), surfactants (such as sodium dodecyl sulfate and sodium 2- acyloxy bond sulfonate), thickeners (such as carboxymethyl cellulose and antler glue), sweeteners (such as glycerol and sodium cyclohexylamine sulfonate) and preservatives (such as potassium sorbate and sodium benzoate). And pigment, essence, etc. Special toothpaste is a kind of toothpaste with special properties. Fluorine toothpaste can effectively prevent dental caries by adding active substances such as sodium fluoride and stannous fluoride. Chlorophyll toothpaste can effectively prevent gum bleeding and bad breath. Enzyme toothpaste can decompose residual food, effectively clean the mouth and prevent insects from eating. Medicated toothpaste can treat oral diseases by adding drugs to toothpaste. Huang Cen toothpaste and grass coral toothpaste on the market.

Question 8: What can toothpaste tubes be used for? A long time ago, toothpaste skin was made of lead, and the recycling price of lead was relatively high, so some people specially bought toothpaste skin; Lead is toxic and will be phased out.

Later, the toothpaste tube was made of aluminum. Although the recycling price of aluminum is ok, aluminum is very light, and many toothpaste tubes don't have much weight, so fewer people accumulate recycling.

At present, almost all toothpaste tubes are plastic, and the recycling price and weight have doubled, so people who accumulate and recycle toothpaste tubes are basically extinct.
