Ascorbyl Glucoside, popularly known as AA-2G, is a stable type of vitamin C that can be mixed in water immediately. It is synthesized by glucol and L-Ascorbic Acid.

 

It is effective both in whitening to brighten the skin. And the reduction of free radicals Stimulate the synthesis of collagen of the skin.

 

Difference between Ordinary L-Ascorbic Acid and Stabilized Vitamin C (AA-2G)

- AA2G ™ is stable even in water. Or the heat does not exceed 40 degrees, making it easy to mix.

- AA2G ™ has the same bioavailability as L-Ascorbic Acid, unlike other Vitamin C derivatives. Such as Sodium Ascorbyl Phosphate (SAP) / Magnesium Ascorbyl Phosphate (MAP). Which cannot be easily absorbed into the skin  

 

Figure 1: Comparison of the stability of AA-2G and Vitamin C (L-Ascorbic Acid) in water. Found that AA-2G is clearly more stable than L-Ascorbic Acid.

 

Figure 2: Comparison of uptake into fibroblast in the subcutaneous layer. AA2G ™ can be absorbed into the skin for a longer period of time. Even at lower levels of Vitamin C L-Ascorbic Acid in the first

 

Figure 3: Comparison of skin applications where the degradation of the skin AA2G ™ and is easily applied, even compared to L-Ascorbic Acid, which can be used immediately without further degradation.

 

 

Figure 4: Comparison of whitening efficacy AA2G ™ shows that Can help fade the skin color.

 

 

Mixing instructions:

 

AA2G is highly acidic. When mixed in water But it is stable in pH range 6.5-6.8. Mixing requires a pH Meter to measure and adjust the pH to the appropriate level. Example of dissolving AA2G in water

 

In the process of dissolving AA2G with water, the pH of the liquid may drop to a very low level.Due to the high acidity of AA2G, it is recommended to add Citrate Buffer as shown below. To prevent some of the AA2G from losing its quality. In the period that is under high acidity

 

Preparation of Citrate Buffer: mix Citric Acid 1%, Sodium Citrate 15%, Water 84%

Using Citrate Buffer at the same rate as AA2G in the formula. For example, if AA2G 2% was used in the formula, use Citrate Buffer 2% as well.

By mixing Citrate Buffer with the formula water, AA2G is added to the formula and measuring the pH, then adjusting the pH by adding alkali such as TEA (Triethanolamone) Or Sodium Hydroxide by adjusting the pH in the range of 6.5-6.8, which will help make AA2G the most stable

 

If it is not comfortable to prepare Citrate Buffer according to the instructions above, please use. L-Arginine At a rate of 1: 2 ( L-Arginine 1 part to 2 parts AA2G) mix well. Then dissolve in water at the same time L-Arginine It can help control the pH value so that AA2G does not deteriorate.

 

Prohibited formulas Safe-B3 or Zinc PCA As this will affect the stability of AA-2G

 

Differentiate each type of Vitamin C that the company sells:

1. Ethyl Ascorbic Acid : Vitamin C is soluble in water, highly stable, easy to mix, moderate efficiency. In the field of radiance (whitening)

2. Perfect-CTM (Ascorbyl Tetraisopalmitate) : Vitamin C soluble in oil Moderately stable High efficiency Both wrinkles (anti-oxidant) radiance (whitening) and softness (collagen level) of the skin.

3. Ascorbyl Glucoside (AA2GTM, Stable Vitamin C) : Vitamin C is soluble in water and is moderately stable. It has a sophisticated blending process (pH must be adjusted accordingly), highly effective in whitening and aging (anti-oxidant).

4. Vitamin C (L-ascorbic acid) Ultra-Fine , Vitamin C (L-ascorbic acid) Fine : Vitamin C dissolves in water, can dissolve very quickly in water and disperses very well. Low stability It has a complicated mixing process. High efficiency Both wrinkles (anti-oxidant) radiance (whitening) and softness (collagen level) of the skin.

5. Vitamin C (L-ascorbic acid) : A. Vitamin C is soluble in water, low stability It has a complicated mixing process. High efficiency Both wrinkles (anti-oxidant) radiance (whitening) and softness (collagen level) of the skin.

6. Stabilized Vitamin C (Natural-C GlycolTM) Serum : A. Finished vitamin C base is highly stable. But cannot customize or add other ingredients Because it will affect the stability of the bass High efficiency Both wrinkles (anti-oxidant) radiance (whitening) and softness (collagen level) of the skin.

7. Magnesium Ascorbyl Phosphate (MAP) : Water soluble vitamin C High stability, easy mixing, moderate efficiency. In the field of radiance (whitening)

8. Max-CTM Serum (Compare The Ordinary Vitamin C Suspension) : A. Ready-made vitamin C base is highly stable, silicone-free, with a high concentration of 23% of Vitamin C from 2 forms of Vitamin C to be able to work perfectly. Cannot customize or add other ingredients. High efficiency Both wrinkles (anti-oxidant) radiance (whitening) and softness (collagen level) of the skin.

9. Vitamin C Ester (Ascorbyl Palmitate) : Oil-soluble vitamin C It is suitable for use as an anti-oxidant in oil formulas, with little other efficacy. When compared with other forms of Vitamin C

 

Suggested use ProtecTM OX And ProtecTM UV In the formula to help protect Vitamin C from quality deterioration

 

Usage: Can be used in all kinds of Anti-Aging, whitening products such as gel, serum, lotion or cream.

Mixing method: Mix in water where the temperature of the cosmetics must be below 50. ° C And the formula must have a pH in the range of 6.5-6.8, if outside this pH range will cause AA2G to deteriorate faster. Please see above for more details.
