Tromethamine, alias Tris, tris(hydroxymethyl)aminomethane, CAS77-86-1. It is a white crystal or powder. Tris (tris(hydroxymethylaminomethane)) has a wide range of uses. It can be used as an intermediate for fosfomycin, as well as a vulcanization accelerator, mineral oil, and paraffin emulsifier. It can also be used as an acid gas absorbent to prepare buffers, surfactants, emulsifiers and accelerators. There is also a magical use, tromethamine is also a mild and safe cosmetic additive.

The pKa of tromethamine at 25°C is 8.06, and the pH buffer range is 7.0-9.0. The most important role played in cosmetics is to adjust the pH of the product. Because the skin can only be in the best state of absorbing nutrients within the normal pH range (4.5-6.5), the pH value of cosmetics is very important. After adding tromethamine and other acid-base regulators, it can make the product close to the PH value of the skin surface, making it more gentle and skin-friendly.
In addition, tromethamine is also commonly used to neutralize thickeners. When mixed with carbomer, it can reduce the stickiness of lotions, creams and other products, improve the cell respiration efficiency of facial skin, and make cell respiration more smooth. Clogged pores.
