Why can toothpaste remove stains, and can toothpaste remove oil stains

Toothpaste contains very fine calcium carbonate.

Powder, calcium carbonate powder with a certain hardness, can remove oil stains from the surface of objects. Surfactants are also found in toothpaste.

This substance can dissolve oil stains and is similarly soluble.

Toothpaste is a complex mixture. It is usually made up of friction agents such as calcium carbonate, dicalcium phosphate, calcium pyrophosphate, silicon dioxide.

aluminum hydroxide), humectants (e.g., glycerin.

Sorbitol, propylene glycol, polyethylene glycol.

and water), surfactants (such as sodium dodecyl sulfate, sodium 2-acyloxy bond sulfonate, sodium lauroyl sarcosinate),

Thickeners (e.g. carboxymethyl cellulose, staghorn pectin, hydroxyethylcellulose, xanthan gum, guar gum, carrageenan, etc.), sweeteners (e.g., glycerin, sodium cyclohexylasulfonate, sodium saccharin, etc.), preservatives (e.g. potassium sorbate.

Salt and sodium benzoate.

Mixed with active additives (such as chlorophyll, fluoride), as well as pigments, flavors, etc. Special toothpasteIt is a toothpaste with special properties.

Enzyme toothpaste can decompose residual food, which is effective in cleaning the mouth and preventing insect moths. Medicated toothpasteAdding drugs to toothpaste can ** oral diseases. The most advanced skullcap toothpaste and grass coral toothpaste on the market have a significant effect on gum bleeding, gum redness and swelling, bad breath, and dental hypersensitivity.

Because the most important ingredients in toothpaste are abrasive agents, such as calcium carbonate, dolomite, aluminum hydroxide, silicon dioxide, dicalcium phosphate, etc., using the friction particles contained in toothpaste, it is easy to remove some dirt that is difficult to remove.

1. Toothpaste can clean rust and scale on stainless steel.

2. Toothpaste can clean silver jewelry and prevent oxidation. Silver jewelry will oxidize after being in contact with air for a long time, making the luster of silver jewelry dull, at this time, you can use toothpaste to clean the silver jewelry, and the silver jewelry will return to its original luster.

3. Toothpaste can clean up the dirt on leather products.

4. Toothpaste can clean ceramic tableware, remove dirt and dirt. Ceramic tableware will generally be available to everyone, but after a long time, there will be dirt and some will be yellow, you can clean it with toothpaste, if the dirt is more serious, you can soak it in hot water and clean it up.

5. Toothpaste can effectively bleach clothes.

6. Toothpaste can clean the dirt of sneakers.

The physical action is greater than the chemical effect of toothpaste decontamination. Because toothpaste is mainly made of very, very fine particles. Removing dirt is like gently grinding the surface of an object with sandpaper to remove the dirt.

It's just that the particles are extremely fine and very fine, and they are not very visible to the naked eye. Therefore, it is important not to use toothpaste on glasses, lenses, monitors, etc.

Actually, the principle is very simple, toothpaste contains very fine calcium carbonate powder.

Calcium carbonate powder with a certain hardness can remove oil stains from the surface of objects.

Toothpaste also contains surfactants, which dissolve oil stains and are similarly soluble.

Similar and compatible, there should be in the chemistry textbook of the second year of high school

The truth behind toothpaste stain remover! Microscope magnification 200 times a **!

Because toothpaste has a cleaning effect.

Toothpaste can remove grease stains, and using the friction particles contained in toothpaste, some dirt that is difficult to remove can be easily removed.

Toothpaste contains surfactants that can remove grease, and in order to clean the dirt in the mouth, a neutral detergent - sodium lauryl sulfate is widely used. It foams quickly, foaming and cleansing dirt from the mouth.

Toothpaste is a great way to remove stains.

1. People sweat a lot in summer, and the sweat stains on the collar and cuffs are not easy to wash. Clothes stained with animal and vegetable grease, squeeze some toothpaste on it, rub it lightly a few times, and then wash it with water to remove the grease.

2. When polishing leather shoes, wipe a little toothpaste and shoe polish to make the leather shoes brighter.

3. After cleaning the fish, there will always be a fishy smell that is difficult to remove on the hands, first wash the hands with soap, and then rub the toothpaste repeatedly, and the fishy smell will be easy to remove after washing with water.

4. Toothpaste can be used to wipe the glass, and the dirt on the glass can be wiped with a cloth dipped in toothpaste, which can be wiped clean and bright.

Toothpaste is stained because it contains a friction agent.

Toothpaste contains dicalcium phosphate (calcium diphosphate dihydrate cahpo4?2H2O and dicalcium phosphate anhydrous salt CahPO4): Dicalcium phosphate is divided into two types: dihydrate salt and anhydrous salt of dimolecular water.

Dihydrate salt and other components have good mixability, but due to the high hardness of anhydrous salt, the friction is strong.

Toothpaste can be used to wash dishes. Because toothpaste contains a certain amount of friction agent and also has a decontamination effect, it is easy to remove stains from the bowl by squeezing the toothpaste on a dishcloth and rubbing it. So can you wash dishes with toothpaste, and what else is there, you can continue to understand.

1. Toothpaste can be used to wipe silverware, and a layer of black oxide layer will appear after the silverware is not used for a long time.

2. Toothpaste can be used to clean small white shoes, first squeeze the toothpaste on the brush, and then brush the stains on the upper, and soon clean the stains on the upper.

3. Toothpaste can be used to clean the tea stains in the teacup, first squeeze the toothpaste into the cup, and then brush it repeatedly with a cup brush until the tea stains are removed.

4. Toothpaste can be used to wipe leather shoes, and an appropriate amount of toothpaste and shoe polish can be neutralized together to wipe leather shoes, which can make leather shoes brighter.

Toothpaste can remove grease. Since the main ingredient in toothpaste is surfactant, it can effectively reduce the tension on the surface of the aqueous solution, so that the oil film on the surface of the object can be curled into fine particles, and then separated by friction and the impact of the water flow to achieve the effect of degreasing. In short, through the above content, I believe that everyone has an understanding of the question of "can toothpaste wash dishes", it can be known that toothpaste can be used to wash dishes, but the main function of toothpaste is to clean teeth and purify the mouth, so it is not recommended to use toothpaste often to wash dishes.
