Silicon dioxide for toothpaste is characterized by good thixotropy and wear resistance. Because of its good thixotropy, it can effectively solve the problem of toothpaste dregs. At the same time, because of its wear coefficient and teeth matching, the wear degree of teeth is reduced and the chemical properties are stable.
The toothpaste uses dental silica as an amorphous powder, tasteless, insoluble in water or acid, is chemical inert, and has good solubility with fluoride and other raw materials in toothpaste. The structure and granularity of silica can be controlled by the production conditions. According to the variety of toothpaste, three kinds of production are produced: friction, mixed type and thickening type.
Specification: 300 mesh -400
In the existing production of toothpaste industry, most of the calcium dihydrogen phosphate, light calcium carbonate and alumina are used as filling agents. Most of these substances exist only as filler, and because of the use of large amounts of phosphide, it is easy to cause the water to be rich in phosphorus and cause two environmental pollution. Coefficient and tooth wear resistance coefficient is too large, excessive use of tooth damage has been proven. The toothpaste is made of silica gel powder, which is made of high quality silica gel, and is prepared according to the selection of the wear resistance coefficient of human teeth. It also solves the problems of easy to join and drop in the use of toothpaste. It has been proved that the silica gel has the wear resistance coefficient that matches the teeth, reduces the wear to the teeth and increases the teeth. Whiteness; and the use of silica gel toothpaste at the time of use quickly form slurry, not easy to dregs, so that each toothbrushing toothpaste consumption greatly reduced.
The advantage of silica for toothpaste:
1, the physical and chemical properties of the toothpaste are stable, and it does not react with other ingredients in toothpaste, such as fluorides, Chinese herbs, spices, etc., and thus has the best compatibility.
2。The use of silicon dioxide is a safe and non-toxic food additive and drug excipient, which is widely used all over the world. It is because of its stable physical and chemical properties. It will not affect the gastric juice and saliva of the human body. Therefore, it has the best safety.
3, the density of silica gel used for toothpaste is lower than that of other materials, which means that more toothpaste can be produced by using the same weight paste.
4. The toothpaste is used as an excellent stabilizer. It has been widely used in food, beverage, medicine and other aspects. If only as a beer stabilizer, the world consumes tens of thousands of tons every year in the world. The toothpaste has excellent storage stabilizers with silica, especially the stability of fluoride in dental caries toothpaste.
