I don’t know if you will feel this way every time you buy a skin care product. Whenever someone wants to talk to you about a skin care product, TA will definitely tell you what ingredients are added in it, which is very powerful. Specifically for whitening/anti-aging/wrinkle removal functions, the effect is very good. At this time, if you don’t understand the ingredients very well, is it possible to silently think "so amazing" in your heart and then take out your phone and prepare to pay, as the saying goes Well said, I don't want to be fooled. I have to understand it first. Today I will introduce a commonly used additive in skin care products-tromethamine (TRIS) to see what role it plays in skin care products and whether it is safe.

What is tromethamine

Tromethamine, also known as Tris, or Tris. It is white crystal, odorless,

The taste is slightly sweet and bitter. In biochemistry and molecular biology experiments, it is the most commonly used raw material for the preparation of buffers. Desheng is

Professional manufacturer of tromethamine. In addition, tromethamine is also used in the preparation of surfactants, vulcanization accelerators and some drugs.

Intermediate, can also be used as emulsifier for cosmetics (cream, lotion), mineral oil and paraffin wax.

How safe is tromethamine (TRIS)

There is also a commonly used acid-base regulator in cosmetics such as sodium hydroxide, sodium citrate, and triethanolamine. Butamine

Triol is the safest among them. It is not easy to cause skin irritation and allergic reactions. It can also be used for sensitive skin. Moreover, the amount of additives added in cosmetics is not large, and there will be no safety hazards in normal use.

The role of tromethamine (TRIS) in cosmetics

Because the composition of cosmetics is complex, the pH varies greatly, which not only depends on the variety, source and formula of the raw materials, but also

It is related to the participation of microorganisms, air oxidation and the failure of preservatives during storage. So need to add buffer to adjust

PH value, make it reach the pH within the allowable range, the skin can only be absorbed in the normal PH range

The best state of nutrition, tromethamine plays this role, which can maintain the pH value of the entire system without significant changes.

Tromethamine can also be used as an odor regulator in cosmetics containing amine salts to adjust the amine odor generated by friction when applying cosmetics, so as to avoid any residual or sustained odor release.

In fact, the additives and the production process of skin care products are much more complicated than imagined. Most of them are to ensure the effect and quality of skin care products. The same is true for tromethamine. Whether it is allowed to be added and how much it is added are regulated by countries. Products that are normally put on the market after being registered by the National Inspection Bureau are generally not correct. No need to worry too much about the burden and injury caused by the skin.
