Ascorbic acid 2-glucoside is a stabilized derivative of vitamin C, produced by enzymatic transglycosylation of L-ascorbic acid with dextran. It is supplied as a white to off-white crystalline powder with a purity of 99% (HPLC).
The glucose moiety protects the labile enediol group, making the molecule resistant to oxidation and heat – a practical advantage over plain ascorbic acid in formulations where stability is critical. It remains highly water-soluble and is typically used at lower concentrations than ascorbic acid due to its higher molecular weight.
Formulators turn to this ingredient for skin-brightening serums, anti-aging creams, and oral supplements where a stable vitamin C source is needed. It is also used in functional beverages and powdered drink mixes.
In skincare, ascorbic acid 2-glucoside is incorporated into brightening serums, lotions, and creams, often at 1–3% to even skin tone and reduce hyperpigmentation. It is compatible with most cosmetic bases and can be added to water or oil phases. In the supplement sector, it appears in capsules, tablets, and powdered drink mixes as a stable vitamin C source. Beverage manufacturers use it in ready-to-drink products where clarity and shelf life matter.
Ascorbic acid 2-glucoside is manufactured by enzymatic transglycosylation, where L-ascorbic acid reacts with a glucose donor such as dextran in the presence of cyclodextrin glucanotransferase. The reaction yields a mixture that is then purified by ion exchange and crystallization to achieve high purity. The final product is a crystalline powder that meets the 99% assay specification.
