As the cosmetic industry moves toward high-efficacy, bio-identical, and stable formulations, CD BioGlyco delivers a state-of-the-art ascorbyl glucoside production service. Ascorbyl glucoside is a premier stabilized derivative of vitamin C, formed by the attachment of a glucose molecule to L-ascorbic acid. While pure vitamin C is notoriously prone to thermal and oxidative degradation, our biosynthetically produced ascorbyl glucoside remains inactive in the formulation until it is applied to the skin, where natural alpha-glucosidase enzymes gradually release active vitamin C. This "depot effect" ensures prolonged antioxidant protection, collagen stimulation, and skin brightening. By integrating advanced synthetic biology and precision enzymatic catalysis, CD BioGlyco provides a high-titer production pathway that eliminates the need for harsh chemical reagents, offering a "green" and sustainable solution for global skincare brands.
Core Technologies
We utilize a multi-disciplinary technology stack to redefine the synthesis of glycosylated antioxidants:
We deploy high-selectivity CGTase variants designed through molecular docking to specifically target the C-2 hydroxyl group of ascorbic acid, ensuring 100% regioselectivity.
One-Pot Chemoenzymatic Transformation
A streamlined process that couples carbohydrate donor regeneration with transglycosylation, significantly reducing the accumulation of inhibitory byproducts.
Microbial Fermentation Chassis
Utilizing optimized Bacillus and Escherichia coli strains engineered for the high-yield extracellular secretion of catalytic enzymes, facilitating simplified downstream processing.
Advanced Membrane Separation
Implementation of multi-stage ultrafiltration and nanofiltration to remove unreacted substrates and higher-order maltooligosaccharides without damaging the sensitive antioxidant core.
Controlled Vacuum Crystallization
A proprietary crystallization protocol that produces ultra-pure, non-hygroscopic white crystals with superior solubility and stability in diverse cosmetic bases.
Synchronizing Stability and Efficacy through Molecular Glycosylation.
The service scope of our ascorbyl glucoside production platform is specifically tailored to meet the rigorous demands of the modern cosmetic and dermatological industries. We provide a full-cycle biosynthetic solution, covering everything from initial strain development and enzyme optimization to pilot-scale manufacturing and final ingredient characterization. Our platform specializes in the production of high-purity crystalline ascorbyl glucoside (>98%), designed for premium anti-aging and skin-brightening formulations where clarity and color stability are critical.
Beyond standard production, we offer custom process development for clients looking to optimize yields from specific carbohydrate donors or integrate production into existing fermentation facilities. Our scope includes the development of synergistic antioxidant complexes, where ascorbyl glucoside is co-produced or formulated with other bioactive glucosides to enhance transdermal delivery and biological performance. We provide regulatory support and safety documentation, including heavy metal analysis, microbial limit testing, and residual solvent reports, ensuring that our ingredients are ready for global market entry. Our capabilities extend to stability testing services, where we evaluate the performance of our ascorbyl glucoside within your specific formulation matrices under accelerated aging conditions. With a commitment to "green chemistry," we ensure that every gram of ascorbyl glucoside produced is free from toxic catalysts and environmentally harmful solvents, empowering your brand to deliver high-performance skincare that aligns with the highest sustainability standards.
Workflow
Our production workflow is a rigorous six-stage process designed to move from microbial design to high-purity crystalline product.
Enzyme Production & Preparation
We cultivate our proprietary microbial strains to produce high-activity CGTase or alpha-glucosidase, followed by precision purification to ensure the biocatalyst is free from off-target hydrolase activity.
Substrate Dissolution & Stabilization
L-ascorbic acid and high-purity starch or maltodextrin donors are dissolved in a strictly anaerobic, temperature-controlled environment to prevent premature oxidation of the vitamin C.
Biocatalytic Transglycosylation
The enzymatic reaction is initiated in a bioreactor where real-time monitoring of pH and temperature ensures the optimal formation of the alpha-D-glucopyranosyl-L-ascorbic acid linkage.
Reaction Termination & Decolorization
The enzymatic process is quenched, and the crude mixture is treated with high-efficiency activated carbon and ion-exchange resins to remove residual pigments, proteins, and inorganic salts.
Polished Purification
Utilizing preparative chromatography and nanofiltration, we isolate the mono-glucoside from any poly-glycosylated variants, achieving a purity profile that meets or exceeds global "safety assessment" standards.
Crystallization & Final Analysis
The pure solution undergoes vacuum crystallization and micronization, followed by comprehensive HRMS and NMR analysis to verify structural identity and batch-to-batch consistency.

Results: This comprehensive review examines the potential of ascorbic acid as a cosmeceutical active ingredient for increasing dermal collagen to counteract skin aging. The author details the biochemical basis for ascorbic acid's dual role as an antioxidant and an essential cofactor for collagen-synthesizing enzymes, and reviews clinical evidence supporting its ability to enhance collagen and improve signs of photoaging. A central focus is the systematic analysis of strategies to overcome ascorbic acid's major limitations of instability and poor skin absorption. These include developing stabilized ascorbic acid derivatives (e.g., ascorbyl glycosides, hydrophobic precursors), optimizing formulations (e.g., nanoparticles, liposomes), and combining topical application with procedures like iontophoresis. The review also highlights emerging combination therapies, proposing that co-administering ascorbic acid analogs with specific amino acid precursors like glycinamide can synergistically boost collagen production by acting on different stages of its synthesis pathway.
Applications
Premium Anti-Aging Serums
Incorporating high-concentration ascorbyl glucoside to target the dermal-epidermal junction, promoting long-term collagen I and III synthesis, and improving skin elasticity while protecting against oxidative stress induced by environmental pollutants and lifestyle factors.
Targeted Skin Brightening Treatments
Formulating intensive creams and spot treatments that utilize the sustained release of vitamin C to inhibit melanogenesis, effectively reducing the appearance of age spots, sun damage, and post-inflammatory hyperpigmentation across all skin types.
Daily Environmental Defense Lotions
Adding stabilized Ascorbyl Glucoside to daily moisturizers to provide a 24-hour antioxidant shield, neutralizing free radicals generated by UV radiation and urban pollution, thereby preventing the early onset of photo-aging.
Sensitive Skin and Post-Procedure Care
Developing non-acidic, pH-neutral brightening products for individuals with compromised barriers or those recovering from chemical peels and laser treatments, where traditional vitamin C would cause unacceptable stinging or redness.
Advantages
Precise C-2 Site-Specific Modification
Utilizing our proprietary CGTase library, we ensure the glucose is attached specifically to the C-2 hydroxyl. This is the only modification that provides maximum stability while maintaining complete bioavailability upon enzymatic cleavage by skin alpha-glucosidases.
Exceptional Solubility in Aqueous Systems
Our crystalline Ascorbyl Glucoside dissolves instantly in water-based formulations, enabling the creation of clear serums and light lotions that are free from the grittiness or crystallization issues associated with other vitamin C derivatives.
Non-Irritating Neutral pH Compatibility
Unlike L-ascorbic acid, which requires a highly acidic pH (<3.5) for stability, our ascorbyl glucoside is perfectly stable at pH 5.0–7.0. This allows formulators to create high-performance products that are gentle enough for sensitive skin and post-procedure recovery.
Sustained Bioavailability and Depot Effect
Once applied, our modified antioxidant provides a steady release of vitamin C into the epidermis. This sustained release leads to more consistent collagen synthesis and melanin inhibition compared to a single "burst" of native ascorbic acid.
