L-Ascorbic Acid 2-Glucoside Powder

L-Ascorbic Acid 2-Glucoside Powder - Premium Grade Cosmetic Active Ingredient

Shaanxi Hongda Phytochemistry Co., Ltd. is a professional manufacturer and supplier of L-Ascorbic Acid 2-Glucoside Powder, which brings you great benefits that are directly applicable to your cosmetic formulations and market success. As a registered raw material plant, we provide you pharmaceutical-grade quality, with over 20 years of production experience to address the most difficult difficulties in the business. Our product solves the major pain issues that have troubled formulators for years: Vitamin C instability, oxidative browning and skin irritation. With our superior synthesis technique and 100,000 purification workshops, we provide a stable water-soluble derivative that keeps its activity during manufacture and shelf life.

Product Introduction

The product represents a breakthrough in stable Vitamin C technology for cosmetic and skincare applications.  This pharmaceutical grade active component combines the known efficacy of Vitamin C with the stabilising effects of glucose bonding, resulting in a highly soluble white crystalline powder. When added to your products, this ingredient penetrates the skin barrier and releases pure Vitamin C by enzymatic hydrolysis, offering greater brightening, anti-aging and antioxidant benefits without the usual instability problems. Our product preserves thermal stability and resistance to oxidation, so you are able to manufacture crystal clear serums and exquisite formulas that are effective for their shelf life.

Third Test Report

Testing Report Authority: We collaborate with internationally recognized third-party testing agencies including SGS and Eurofins to provide you with comprehensive verification of product quality and safety.

Heavy Metal Screening: Testing for ICP-MS confirms compliance to global cosmetic standards, with Lead (Pb) <10ppm, Arsenic (As) <2ppm and Mercury (Hg) <1ppm, to ensure your products fulfil REACH and international safety criteria.

L-Ascorbic Acid 2-Glucoside Powder Advantages

Unique Stability Profile: Our glucoside-bound structure offers greater thermal and oxidative stability than conventional Vitamin C, which oxidises within hours of contact to air and light. You can make formulations at high temperatures without worrying about degradation, and your end products remain white and clear for the life of the product.

Compatible with a Neutral pH: This ingredient is effective in the pH range of 5.0-7.0 and avoids the formulation difficulties and skin sensitivity associated with acidic Vitamin C products. You have the ability to produce delicate formulas for sensitive skin, with strong brightening effects.

Enhanced Bioavailability: Alpha-glucosidase enzyme, naturally present in skin cells, selectively hydrolyses the glucose bond, releasing pure Vitamin C directly where it is required. This regulated release method provides sustained action and better penetration than free ascorbic acid.

Specification

L-Ascorbic Acid 2-Glucoside Powder Application

Premium Whitening Skincare: Use at concentrations of 0.5%-2.0% in brightening serums, spot correctors and dark circle treatments. The substance inhibits the tyrosinase enzyme activity and lowers melanin synthesis without the yellowing impact that degrades the aesthetics of typical Vitamin C preparations.

UV Defence Formulations: Combine with sunscreen actives to generate broad spectrum photo-protection solutions. UV filters limit sunlight and L-Ascorbic Acid 2-Glucoside Powder​​​​​​​ neutralises the free radicals produced by UV rays. This antioxidant defence reduces photo-aging and inflammation.

Production Process

Step 1 – Raw Material Selection: Pharmaceutical grade L-Ascorbic Acid, glucose are procured from approved vendors, and we do incoming inspection for purity ≥99.5% and heavy metal compliance. The foundation of the exceptional quality of the final product is the use of only premium quality raw materials in manufacture.

Step 2 – Enzymatic Synthesis: Under controlled temperature and pH conditions, specialised enzymes catalyse the particular glycosylation reaction that links glucose to the C-2 position of ascorbic acid. This particular synthesis gives a very stable glucoside structure with low impurities and free ascorbic acid.

Step 3 – Purification and Crystallization: In our 100,000-level purification workshop, the reaction mixture is purified by multi-stage filtration, activated carbon treatment and controlled crystallisation. We obtain superior purity levels ≥99.0% with crystal clarity and optimum particle size dispersion.

Step 4 – Drying and Milling: The crystalline product is dried under vacuum at controlled temperatures below 60°C and then milled through 80-mesh screens in a dust-free atmosphere. The powder has moisture content ≤1.0% and homogeneous particle size, which provides excellent flowability and solubility.

FAQ

Q: What is the recommended use concentration of the substance in cosmetic formulations?

A: The optimal concentration range is 0.5%-2.0% for facial skincare products. You can create up to 3.0% for intensive lightening treatments and 0.5%-1.0% works well for maintenance products. The ingredient remains stable and effective throughout this range without irritation concerns.

Q: Is this substance more stable and effective than pure L-ascorbic acid?

A: Pure L-Ascorbic Acid oxidises very fast and requires a pH of <3.5. Our glucoside derivative is stable at neutral pH 5.0-7.0 and does not oxidise in manufacture and storage. Once applied, skin enzymes convert it to pure Vitamin C, so you have the same effectiveness without the formulation problems and irritation possibilities.

Q: What is the shelf life of the product, and what storage conditions are required?

A: The powder is stable for 24 months when stored in sealed containers in a dry place away from direct light at a temperature of less than 25°C. We recommend keeping it in original Packaging (fibre drums) until usage to maximise stability.
