L Ascorbyl 2 Glucoside AA-2G

Ascorbyl Glucoside or popularly called AA-2G is a stable type of vitamin C that can be mixed in water immediately. Synthesized by combining glucose sugar with L-Ascorbic Acid.

Effective in whitening and brightening the skin. and reducing free radicals Stimulates the synthesis of collagen in the skin.

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

- AA2G™ is stable even in water. or heat at a level not exceeding 40 degrees, making it easy to use and mix

- AA2G™ has the ability to be absorbed into the skin as well as L-Ascorbic Acid, which is different from other Vitamin C derivatives such as Sodium Ascorbyl Phosphate (SAP) / Magnesium Ascorbyl Phosphate (MAP) which cannot be absorbed. easily into the skin 

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

Mixing instructions:

AA2G will be highly acidic. When mixed in water But it is stable in the pH range of 6.5-6.8. Mixing must use 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 into water, the pH of the liquid may drop very low. Due to the high acidity of AA2G, it is recommended to add Citrate Buffer as in the example below. To prevent AA2G from losing some quality. During the period under high acidity

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

Use Citrate Buffer at the same rate as AA2G in the recipe. For example, if you use 2% AA2G in your recipe, use 2% Citrate Buffer as well.

By mixing Citrate Buffer with water in the formula, then adding AA2G to the formula and measuring the pH, then adjusting the pH by adding an alkali such as TEA (Triethanolamone) or Sodium Hydroxide, which must be adjusted to keep the pH within the range of 6.5. -6.8, which will help make AA2G extremely stable.

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

The formula does not contain Safe-B3 or Zinc PCA as they will affect the stability of AA-2G.
