Many cosmetics on the market claim to be natural without additives. However, this is impossible. Effective skin care products must add other ingredients besides natural ingredients, such as anti-corrosion, moisturizing or whitening ingredients. You may find that tromethamine is a very common additive in cosmetics. So what is its role in cosmetics Is it safe

The main additives in cosmetics are as follows:

Antioxidants, preservatives, moisturizers, surfactants, acids, alkalis, salts, spices and other special additives that make cosmetics have special effects, such as vitamins, hormones, phospholipids, anti-inflammatory agents, whitening agents, ultraviolet absorbents, placental extracts, allantoin, Chinese herbal medicine and folk medicine, natural plants, vegetables, fruit extracts, etc.

Tromethamine, also known as tris (hydroxymethyl) aminomethane, or Tris. It is a white crystal, odorless, slightly sweet and slightly bitter. In biochemistry and molecular biology experiments, it is the most commonly used buffer preparation materials. In addition, tromethamine is also an intermediate of surfactant, vulcanization accelerator and some drugs.

CAS: 1185-53-1 tris (hydroxymethyl) aminomethane

The most important role of tromethamine in cosmetics is to adjust the pH value. The pH value of healthy Oriental skin should be between 4.5 and 6.5. Only in the normal pH range, the skin will be in the best state to absorb nutrients. In this range, the skin's flexibility, luster, moisture, etc. are in the best state, can resist the erosion of the outside world. However, the composition of cosmetics is complex and the pH value changes greatly, which not only depends on the variety, source and formula of raw materials, but also is related to the participation of microorganisms, air oxidation and the failure of preservatives during storage. Therefore, it is necessary to add a buffer to adjust the pH value. Due to the existence of tromethamine, the pH value of the whole system can be maintained without obvious change. In addition, it can be used as thickener and moisturizer.

What about the safety of methanol In fact, there are other kinds of substances commonly used to adjust pH value, such as sodium hydroxide, sodium citrate, triethanolamine, etc. However, tromethamine is the safest one, it is not easy to cause skin irritation and allergic reactions, sensitive skin can also use it. Moreover, the dosage added in cosmetics is not much, so there will be no hidden danger in normal use.

Skin care products are composed of a variety of raw materials and chemical molecules, and their substances and production process are much more complex than imagined. These additives are not a sin, but to ensure the function and quality of skin care products. The products listed are generally safe and will not cause burden and injury to the skin.
