AA2G 99% Powder

AA2G 99% Powder – Premium Stable Vitamin C Derivative for Cosmetics & Nutraceuticals

Hunan Clover Origins Biotech Co., Ltd. provides pharmaceutical grade AA2G 99% Powder (Ascorbyl Glucoside) with sophisticated biosynthesis technology. With 25+ years' experience in the business and an annual manufacturing capacity of 5,000+ tonnes, we supply this premium whitening ingredient with ≥99.0% purity certified by HPLC analysis. We have developed a highly water soluble (>100g/100ml at 25°C) and stable formulation at pH 5.0–7.0 that overcomes the oxidative degradation problem encountered with typical L-ascorbic acid formulations. We are an FDA-registered, ISO 9001, HACCP, and FSSC 22000 certified company to assure batch to batch quality consistency with complete testing for Heavy Metals (≤10ppm), Microbiological Safety and Active Ingredients through third party validation via Eurofins and SGS.

What Is AA2G 99% Powder?

The product is chemically L-Ascorbic Acid 2-Glucoside (CAS No. 129499-78-1) and is a stabilized derivative of Vitamin C obtained through the attachment of a glucose molecule to the second carbon position of the ascorbic acid.

This enzymatic alteration makes unstable Vitamin C shelf-stable as an active ingredient. Whereas pure ascorbic acid oxidizes within hours in the presence of light or air, our product is chemically stable in aqueous solutions for long periods of time.

The natural alpha-glucosidase enzymes in the skin slowly break the glucose bond. This distributes the active Vitamin C in a regulated, time-release fashion. You get all the brightening and anti-aging effects without the formulation browning or irritation that sometimes happens with high-concentration serums.

That makes it perfect for producers who are creating clean-label skincare products. Your formulations are white and powerful throughout their shelf life.

Technical Specifications & Properties

Our product meets stringent international quality standards for cosmetic actives and nutraceutical applications.

The superior thermal stability means your formulations withstand typical storage and shipping conditions. The broad pH compatibility allows you to combine it with other popular actives without compromising efficacy.

You can formulate at physiological skin pH (around 5.5), which supports the skin barrier instead of disrupting it. This significantly reduces irritation potential compared to low-pH Vitamin C serums.

Key Benefits & Mechanisms of Action

Skin Brightening & Melanin Inhibition

AA2G reduces the activity of tyrosinase, a crucial enzyme in melanin synthesis. Studies suggest that when taken consistently at 2.0% concentration, it lowers hyperpigmentation and black patches.

Your customers will have a more even skin tone. Its time-release action continues the tyrosinase suppression throughout the day.

Antioxidant Protection

UV radiation and pollutants create free radicals that accelerate skin aging. AA2G scavenges these reactive oxygen species and protects the cellular frameworks from oxidative damage.

It also protects skin from blue light emitted by digital screens. This makes it very applicable to modern consumers concerned about environmental aging concerns.

Collagen Synthesis Support

Vitamin C is a necessary co-factor for the synthesis of collagen. AA2G safely transports this nutrient to skin fibroblasts for Type I and Type III collagen production.

Your anti-aging formulas now have a scientifically confirmed mechanism to improve skin firmness. Regular use diminishes the appearance of fine wrinkles.

Long-Term Stability

Unlike L-ascorbic acid that goes brown and loses potency, AA2G remains white and biologically active. Eliminate the "vitamin C serum turned orange" criticism that is hurting the brand's image.

The stability advantage translates directly into higher customer satisfaction and fewer product returns.

Applications Across Industries

Cosmetics & Personal Care

AA2G is a star ingredient in brightening serums, anti-aging creams, eye treatments and daily moisturizers. It is a great UV filter to add to sunscreens for some antioxidant protection as well.

Formulators love that it plays nice with Niacinamide, Hyaluronic Acid and peptides. You can develop complex multi-active formulations without concern for ingredient interaction or pH conflict.

Nutraceuticals & Dietary Supplements

AA2G 99% Powder is becoming a popular stable form of Vitamin C in beauty-from-within supplements. It is best used in candies, effervescent pills and ready-to-drink beverages, where ascorbic acid would normally decay quickly.

Your supplement brand can provide a differentiated product with proven bioavailability claims.

Functional Foods & Beverages

Vitamin C source for functional foods, health beverages, protein bars and functional snacks that is resistant to processing temperatures and remains active during shelf life.

Consumers are demanding more useful elements in common foods. AA2G answers this demand with the clean-label appeal.

FAQ

Q: Why choose the product over L-ascorbic acid?

A: AA2G offers superior oxidative stability and does not discolor formulations, while providing the same biological benefits through sustained release. You eliminate the formulation challenges and customer complaints associated with unstable Vitamin C.

Q: What is the recommended dosage for professional formulations?

A: Typically, 0.5% to 2.0% is used for general brightening effects. A concentration of 2.0% is the standard for functional whitening claims in specific regulated markets. Higher concentrations may be used in professional treatments.

Q: Does AA2G require a low pH to be effective?

A: No, unlike L-ascorbic acid which requires pH <3.5, AA2G is stable and effective at pH 5.0–7.0. This makes it much gentler on the skin barrier and easier to formulate with other actives.

Q: Is it compatible with other popular actives like Niacinamide?

A: Yes, AA2G is highly compatible with Niacinamide, Hyaluronic Acid, peptides, and most other cosmetic actives due to its neutral pH stability. You can create sophisticated multi-active formulations without ingredient conflicts.

Q: How should the product be stored for maximum shelf life?

A: Store in a cool, dark place below 25°C in an airtight container. Under these conditions, it typically maintains a 24-month shelf life with no loss of potency.

Q: Can AA2G be used in hot-process formulations?

A: Yes, it maintains stability up to 40°C, making it suitable for most cosmetic manufacturing processes. For optimal preservation of activity, we recommend adding it during the cool-down phase when possible.

Q: Do you provide samples for formulation trials?

A: Yes, we offer free samples with professional technical consultation. Sample requests are processed within 7 working days, including basic stability data and formulation guidelines.
