AA-2G (Ascorbic Acid 2-Glucoside) is a kind of natural vitamin-C, containing glucose stable composition. The component makes vitamin-C to be made cosmetics conveniently and effectively,containing AA-2G Cream and emulsion for skin, through the enzyme on the skin and alpha glycosidase enzyme action, beneficial components in vitamins-C of AA-2G can be sent out slowly.

The AA2G was developed for medication cosmetics in Japan before, to dilute the color, reduce age spots and freckles pigment precipitation. Further studies show that also has other functions, now all over the world use AA-2G , not only used for whitening, but also it can brighten the dark skin,anti-aging, protect the skin in sunscreen products.

Key Technical Parameters:

Functions and Advantage:

1.High stability

Glucose and C2 droxy of vitamin-C connected in the AA-2G , C2 droxyl is natural vitamin C activity places, but also vitamin C the place of decline. Glucose protect vitamin C avoid high temperature, pH, metal ions and other mechanical cracking to effect.

2.Vitamin C activity lasting

When products containing AA-2G for skin, glycosidase activity gradually release the vitamin C, to make vitamin C beneficial ingredients can keep for a long time.

3. Brighten skin

The AA-2G and vitamin C are the same basic function, through the synthesis of melanin inhibiting melanin cells to prevent pigmentation of the skin, reduce melanin content of existing, and reduce skin pigmentation.

4. Simple Formula

Compared with the natural vitamin C, AA-2G better solubility,It’s relatively stable in many pH value environments , especially in the pH value 5 – 7 environment, but also for skin care product formulations of conventional environment. Compared with other vitamin C formula, AA-2G formula is more simple.

5. Healt skin

AA-2G release vitamin C slowly, can pass through the human skin fibroblasts promote collagen synthesis, and increase skin flexibility, AA-2G enables these features more durable.Human skin fibroblasts were placed in the reference conditions, vitamin (AsA; 0.25mM) or AA2G (0.25mM) in about 1-5 days, collagen synthesis and total protein synthesis ratio can be determined, which reflect the AA2G Can promote collagen synthesis, AA2G Excitation effect sustainable 5 whole days.

6. Sunscreen

The skin of directly exposed in the sun will be affected by ozone radiation, this is the cause of skin injury and redness, The slow decomposition of vitamin C of AA2G, has a radiation purification function, and thus reduce skin inflammation and roughness.

Vitamin C

Nowdays Various vitamin C derivatives are used in cosmetics for external use . Pure vitamin C, ascorbic acid or also called L-ascorbic acid (ascorbic acid) has the most direct effect.In contrast to the other variants, it does not first have to be converted into the active form. Studies show that vitamin C supports collagen synthesis and fights free radicals. It is also effective against acne and age spots by inhibiting tyrosinase. However, ascorbic acid cannot be processed into a cream because the active ingredient is too susceptible to oxidation and decomposes quickly. Therefore, preparation as a lyophilisate or administration as a powder is expedient.

In the case of a serum containing ascorbic acid, the formulation should have a strictly acidic pH value to ensure the best possible penetration into the skin. The administration should be an airtight dispenser. Vitamin C derivatives that are less skin-active or more tolerable and that remain stable even in cream bases are particularly suitable for sensitive skin or the thin eye area.

It’s well known that a high concentration of an active ingredient does not mean a better care effect. Only the careful selection and the formulation adapted to the active ingredient ensure optimal bioavailability, good skin tolerance, high stability, and the best possible product performance.
