1. Tris brief introduction
As the handling in biological buffers, tris plays a more important role, not only because of the wide pH range of tris, it can act as a pH regulator. Conventionally, it is white crystal particles, but there are certain requirements for water solubility, and white powder will not meet its requirements better. The pH value of the acid-base indicator is 7-9, and there are other names, tromethamine, ammonium tromethamine, trishydroxymethylaminomethane and so on. Although they are all the same product, different buyers will call them differently based on different fields.
Second, the use of Tris
2. Tris application in cosmetics
With the improvement of peoples quality of life, more and more attention is paid to spiritual life. Among them, the heart of beauty is common to everyone, regardless of men and women: appearance has become an important indicator of first impression (of course I strongly disagree Because I dont have that beauty. The rise and mass use of cosmetics have become inevitable. To make good cosmetics, the ingredients are very important.
The role of Tris in cosmetics is basically to adjust the pH, and it can also be used as a neutralizer. The PH value of healthy Asian skin is slightly acidic, and the ingredients in many cosmetics are very complicated. If you want to adjust the pH value, you must use tris to adjust, so that the entire raw material composition will not change too much. Many people see that tromethamine is a chemical product, and it is very scary to use in cosmetics, and they are afraid of being unsafe. In fact, if the proportion of ingredients is used properly, there is no need to worry about it. Generally, it will not harm the skin.
3.Tris is used for synthesis
Tris with a relatively simple structure can synthesize many products, and the same buffer system, Tris-HCL, Bis-Tris Tricine, TES, TAPS, etc. can all be synthesized with tris. Compared with others, the price of Tris will be cheaper, but the synthesized products can be applied to more fields, and the price will be doubled. Therefore, the synthesis of tris can be said to be a hot pastry.
