ASCORBYL GLUCOSIDE(Cas 129499-78-1) Usage

Biochem/physiol Actions

2-O-a-D-glucopyranosyl-L-ascorbic acid or ascorbyl glucoside functions as a skin whitener and radical scavenger in cosmetics. It is responsible for the bleaching action of bleaching cosmetics. This compound is activated in a manner identical to that of vitamin C. The enzyme present in the epidermal basal membrane, ascorbyl phosphatase, slowly converts 2-O-a-D-glucopyranosyl-L-ascorbic acid into vitamin C, thereby maintaining a high vitamin C level in skin throughout the day.

General Description

AA2G™ is a stabilized ascorbic acid derivative produced from Vitamin C and starch by enzymatic technology developed by Nagase Viita. This proprietary process results in a substance that has greatly improved stability and solubility in water, while retaining the natural biologic functions of Vitamin C.
Uses For healthier, brighter, younger looking skin. AA2G® is a stabilized Vitamin C derivative synthesized from vitamin C and starch by the use of enzymes. It helps inhibit discoloration and degradation, and retains all the biological activity. Ascorbic acid 2-glucoside is used not only for whitening, but also to brighten the skin, which plays a role in protecting the skin in sunscreen products.

Chrysanthemum Morifolium Extract And Ascorbic Acid-2-Glucoside (AA2G) Blend Inhibits UVA-Induced Delayed Cyclobutane Pyrimidine Dimer (CPD) Production In Melanocytes

Sunghan Yim,Jeesun Lee,Hae Jo,Jeff Scholten,Ryan Willingham,Jim Nicoll &Sudhir M Baswan

, Clinical, Cosmetic and Investigational Dermatology Volume 12, 2019

Chrys, AA2G and their blend at various concentrations demonstrated ROS scavenging activity. Though Chrys alone did not show significant melanogenesis inhibition in B16 assay, the blend of Chrys with AA2G demonstrated additive effects in comparison with AA2G alone. The blend of AA2G and Chrys at various concentrations exhibited enhanced efficacy for inhibiting dark CPD compared to AA2G alone.

Supplementation of cryomedium with ascorbic acid–2-glucoside (AA2G) improves human sperm post-thaw motility

, Fertility and Sterility Volume 95, Issue 6, May 2011, Pages 2001-2004

Our data indicate that AA2G confers a protective effect on human sperm motility preservation through the freeze-thaw cycle. This same effect was not seen with ascorbate. Further investigation is required to elucidate a concrete mechanism of action.
