Trehalose is a good substance that is stable in harsh environments. Researchers found it to be of great importance for skin cosmetology and used it in this area. Trehalose is a kind of stable disaccharide that cannot be reduced, which is formed by the combination of two glucopyranose and 1,1-glycosidic bonds. Trehalose is abundant in algae, fungi, insects and invertebrates.

Trehalose 100 is a natural sugar, its main component is free sugar, and it is also one of various glycolipids. Recent studies have shown that exogenous algalose also has a good protective effect on organisms and biological macromolecules. Research in recent years has shown that trehalose has many roles in cosmetics and skin care products.

After the 1990s, with the continuous development of biotechnology and skin care products, the physiological function of trehalose has received extensive attention. Trehalose has shown many magical effects in beauty, skin care and hair care. So, what is the role of trehalose in cosmetics and skin care products? After reading this article, you will understand.

What are the functions of trehalose?

Function 1. Trehalose has a good non-specific protective effect on organisms and macromolecules. Trehalose has a low molecular weight, is easily absorbed by the skin, and plays its special role in water replacement in cells, protects the cell membrane, enhances the cell's anti-drying and anti-freezing capabilities, and improves the skin's adaptability.

Function 2. Reduce the freezing point: reduce the freezing point in the water phase, so that the low temperature stability of the product is greatly improved.

Function 3. Prevent the decomposition of oil: In products containing oil, adding trehalose can effectively inhibit its oxidation and rancidity. Trehalose has obvious inhibitory effect on the oxidation and rancidity of fatty acid and ester products. The Japan Forest and Natural Resources Association found that trehalose can effectively reduce the special body odor in the elderly. Studies have found that middle-aged and elderly sebum contains higher levels of fatty acids and palmitic acid, and is prone to body odor after being decomposed in the human body, while trehalose, a natural sugar, can effectively inhibit the decomposition of oil, thus preventing body odor.

Function 4. The function of preventing protein denaturation and maintaining a variety of protein and polypeptide active ingredients: it has a good retention activity for some biochemical substances that cannot be kept active for a long time at room temperature.

Function 5. Moisturizing: excellent water retention and hygroscopicity, can replace the water in cells, in the case of severe dehydration. Hyaluronic acid and fructose are used in combination to complement each other, which not only has biological preservation, but also has intelligent moisturizing effect, which can keep skin products and cosmetics moisturizing.

6. Anti-radiation: It can effectively remove free radicals and prevent DNA mutation. Trehalose has protective and repairing properties, protecting DNA from radiation damage.

7. Stabilizer of antioxidant "polyphenol".

It is essential to maintain the stability of the active ingredients of the product. There are many skin care products that contain green tea essence on the market today. Green tea is also valued because it contains a lot of tea polyphenols. Green tea is a very active antioxidant, but its use in skin care products is very unstable. Trehalose can inhibit the oxidation of polyphenols and reduce oxidation problems in skin care products.
