What is toothpaste made of? How is toothpaste made?

In the Tang Dynasty of China, we have begun to use traditional Chinese medicine gastrodia, weed, fine pungent and ashen incense, and cold water stone grinding powder to rub teeth, which can be fragrant and clean. In foreign countries, more than 2,000 years ago, the ancient Romans ground pumice stone containing calcium carbonate and brushed their teeth with a brush. In the middle of the 19th century, tooth powder with chalk as the main body generally appeared in the domestic and foreign markets.

At the end of the 19th century, toothpastes in tubes began to appear, which were more convenient to use than tooth powder, but not refreshing. After the end of the Second World War, toothpaste manufacturers made a big fuss about taste and smell, and developed a matrix that replaced chalk with calcium bicarbonate and sodium lauryl sulfate instead of soap, making toothpaste universally popular.

There are a few others:

19 January 2003. The basement of the Austrian National Library. An ancient Egyptian papyrus dating back more than 1,700 years and filled with strange hieroglyphs.

The black ink, made of soot and gum mixed with water, has faded, but the handwriting is still faintly legible. Written in the fourth century C.E., this papyrus describes "the perfect powder to make you smile and whiten your teeth," which is diluted with saliva and becomes a "paste for cleaning teeth": "1 percent ounce of rock salt and dried iris flowers, 2 percent ounce of peppermint and 20 grains of pepper (1 ounce equals about 31 grams)" and these things are crushed and mixed to become the prototype of toothpaste, an indispensable item in your life today.

Toothpaste was first invented by the ancient Egyptians and consists of 1 percent ounce of rock salt and dried iris flowers, 2 percent ounce of peppermint and 20 peppercorns, and these powders turn into a paste when they meet saliva to clean teeth.

During the Tang Dynasty in China, Chinese herbal medicines such as gastrodia, herbs, agarwood, and cold water stone were commonly used to rub teeth, which could clean teeth and remove odors in the mouth.

In 1893, the Viennese Seger invented toothpaste and put the toothpaste into a hose, since then the toothpaste began to develop in large quantities and gradually replace the tooth powder, toothpaste is composed of powdered friction agent, wetting agent, surfactant, adhesive, spice, sweetener and other special ingredients, has a good sterilization and cleaning function.

Toothpaste usage tips:

1. Don't blindly believe in the efficacy, the toothpaste stays in the mouth for too long before it is soaked, and some special toothpastes are difficult to exert their effects in a short time. If your teeth are healthy, you can use regular toothpaste.

2. It is best to use toothpaste instead: long-term use of the same toothpaste to brush teeth will make some harmful oral bacteria develop drug resistance and resistance, so that toothpaste loses the effect of sterilization and tooth protection. It is best to alternate several toothpastes.

3. Don't use a tube of toothpaste for too long, the longer the toothpaste is used, the more opportunities you have to be exposed to the air, the higher the frequency of contact with the toothbrush, and the greater the chance of contact with bacteria.

According to the process formula, the spices, active additives, stabilizers, and saccharin are first dissolved in the pre-dissolution pot or premixed pot with pure water until uniform, and then added to the paste making pot, and then the liquid materials in the liquid storage tank are respectively measured and added to the paste making pot, and then the powder is added; After the powder is added, spices are added, scraper stirring, homogenizing stirring, and grinding. 2. Pinch and make the paste fully mixed evenly, and the grinding purpose makes the paste delicate. After kneading and grinding, a small amount of paste is punched out for inspection, and then it is injected into the paste storage pot for aging, so that the material is naturally cooled to room temperature, and at the same time, the material is fully expanded to form a homogeneous adhesive, which improves the elasticity of the material, and the aging time is about 120 minutes.

3. The filling of the paste is completed on the automatic filling line, and the filling volume, sealing temperature and machine speed should be adjusted during the filling process, and the weight and sealing quality of the toothpaste should be checked regularly. 4. After the filling is completed, the finished products will be processed by automatic cartoning, shrink film heat sealing, packing and other subsequent commercial packaging. After the packaging is finished, it is stacked according to the variety and time, and the inspection is carried out, and after it is qualified, it is stored in the warehouse. ‍

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

Toothpaste is a complex mixture. It is usually composed of friction agents (such as calcium carbonate, dicalcium phosphate, calcium pyrophosphate, silicon dioxide, aluminum hydroxide), humectants (such as glycerin, sorbitol, propylene glycol, polyethylene glycol, and water), surfactants (such as sodium dodecyl sulfate, sodium 2-acyloxy bond sulfonate, sodium lauroyl sarcosinate), thickeners (such as carboxymethylcellulose, staghorn pectin, hydroxyethylcellulose, xanthan gum, guar gum, carrageenan, etc.), sweeteners (such as glycerin, sodium cyclohexylamine sulfonate, sodium saccharin, etc.), A mixture of preservatives (e.g., potassium sorbate and sodium benzoate), active additives (e.g., chlorophyll, fluoride), and pigments, flavors, etc. Special toothpasteIt is a toothpaste with special properties.
