Product Overview
Ascorbic Acid 2-Glucoside (AA2G) is a highly stable form of Vitamin C synthesized by bonding glucose to L-ascorbic acid via a specialized enzymatic process. This molecular structure protects the Vitamin C from oxidative degradation caused by heat, light, and high pH levels—common challenges that often limit the efficacy of standard L-ascorbic acid.
SRBio AA2G acts as a “pro-vitamin.” Once applied to the skin, it is gradually hydrolyzed by the natural enzyme alpha-glucosidase, releasing pure Vitamin C into the deeper layers of the epidermis. This sustained-release mechanism ensures long-lasting biological activity and superior cellular support.

Key Advantages
1. Unmatched Stability in Formulations
Unlike raw Vitamin C, which oxidizes rapidly and turns brown in water-based products, AA2G remains exceptionally stable. This allows manufacturers to create high-potency serums and creams with a long shelf-life and consistent aesthetic appeal, without the need for complex airless packaging.
2. Sustained-Release Bioactivity
AA2G provides a steady supply of Vitamin C over several hours. This gradual release supports the skin’s natural collagen synthesis and helps maintain the structural integrity of the extracellular matrix, promoting a more resilient and youthful-looking skin texture.
3. Support for Even Skin Tone
By modulating the metabolic pathways associated with pigment formation, AA2G helps support a balanced and even skin tone. It acts as an effective agent for formulations targeting skin radiance and the reduction of perceived oxidative damage from environmental stressors.
Manufacturing Excellence
Enzymatic Bio-Synthesis
We utilize a high-precision enzymatic glycosylation process followed by multi-stage crystallization. This ensures the removal of residual glucose and unreacted ascorbic acid, resulting in a white, odorless crystalline powder that meets the highest purity standards for the global cosmetics market.
