Magnesium Ascorbate (CAS 15431-40-0) – Stable Dual-Nutrition Antioxidant Raw Material

1. Physical & Chemical Properties – Solve Formulation & Ocean Shipping Pain Points

Magnesium Ascorbate features excellent water solubility, fully dissolving in pure water to form weakly acidic aqueous solutions, while it cannot be dissolved in organic solvents such as ethanol and acetone.

Compared with regular L-Ascorbic Acid, Magnesium Ascorbate owns a much more stable molecular structure with strong resistance to light and air oxidation. It hardly turns yellow or loses nutritional activity during long-distance sea transportation and long-term warehouse storage.

This raw material has slight hygroscopicity. We adopt 25kg neutral fiber drums with double PE inner lining as export packaging, which completely prevents caking and deterioration caused by moisture during transoceanic delivery, perfectly suitable for global cross-border trade.

2. 4 Core Competitive Advantages

Manufacturers worldwide choose Magnesium Ascorbate mainly for its cost-saving, shelf-life extending and formula-friendly features:
✅ Dual-function single ingredient to cut overall procurement costs
One single raw material delivers both antioxidant activity of Vitamin C and mineral nutrition of magnesium. Factories do not need to purchase pure VC and inorganic magnesium salt separately, which reduces supplier management work, warehouse space and feeding labor. It becomes a top popular clean-label raw material for global formulations.

✅ High oxidation resistance to cut finished product scrap loss
Ordinary Vitamin C oxidizes and discolors easily, shortening the shelf life of beverages, tablets and skincare products. Magnesium Ascorbate maintains stable activity under high-temperature production, long ocean transit and supermarket storage, extending finished goods’ shelf life and lowering brand loss costs.

✅ Fully water-soluble with zero precipitation for all liquid formulations
This powder dissolves clearly without layering or residue, perfectly matching functional drinks, oral liquids, serums, toners and other water-based products, guaranteeing uniform premium appearance of end goods.

✅ Mild & low-irritation formula carrier to expand market segments
Pure L-Ascorbic Acid carries strong acidity that irritates sensitive skin and stomachs. Magnesium Ascorbate owns milder pH value, applicable to children’s dietary supplements and sensitive skincare lines, helping brands explore niche blue-ocean markets.

3. Global Main Application Fields

3.1 Food & Dietary Supplements

CAS 15431-40-0 Magnesium Ascorbate serves as a premium nutritional fortifier for meal replacement powder, sports nutrition drinks, dairy products, multi-vitamin tablets and effervescent tablets. Global health brands widely adopt this dual-nutrition VC-magnesium raw material to create differentiated selling points, standing out from single vitamin competitors in the market.

3.2 Cosmetics & Personal Care

Registered compliant functions: Skin conditioning, Antioxidation.
Magnesium Ascorbate is mild and non-irritating, widely used in moisturizing serums, brightening masks, facial toners and body lotions. It acts as an ideal replacement for irritating pure VC for natural & organic clean-label skincare formulas.

4. Standard GMP Production Process

We adopt liquid-phase synthesis technology using food-grade magnesium sulfite and high-purity L-Ascorbic Acid. The whole production line runs in 100,000-class GMP dust-free workshops with closed-loop control, followed by multi-stage recrystallization purification.

We can customize powder fineness, purity and microbial indicators according to overseas clients’ demands. Food grade and cosmetic grade are produced on separate production lines to avoid batch mixing. Complete production traceability records are reserved for every batch, fully meeting raw material audit standards of all importing countries.

Overseas clients can apply for free small-size samples for laboratory R&D tests. Multiple stable international logistics channels ensure fast sample delivery worldwide; buyers only need to cover shipping fees.
4. Mass in-stock inventory for long-term bulk orders
Self-owned standardized production lines maintain 10,000 tons of stock all year round, no out-of-stock risks in peak seasons. Annual long-term framework supply contracts are supported with fixed delivery cycles to guarantee uninterrupted production for your factory.

5. Customizable indicators to meet global regional regulations
Powder granularity, purity and microbial limits can be adjusted flexibly in line with food & cosmetic regulatory standards of your target import countries.

6. FAQ Section

Q1: What is the difference between Magnesium Ascorbate and regular Vitamin C?

A: Magnesium Ascorbate combines Vitamin C antioxidant effects and magnesium mineral nutrition together, with stronger oxidation resistance and milder pH without easy yellowing. Regular Vitamin C only provides single antioxidant performance, featuring poor stability and high irritation with limited formula application scenarios.

Q2: What certification documents are needed to export Magnesium Ascorbate to Pakistan?

A: We supply full English COA, complete test reports, GMP production certificates and certificates of origin. The whole set of documents fully meets Pakistan customs import inspection standards.

Q3: Are samples free? What is the minimum order quantity?

A: R&D test samples are free, buyers only bear shipping cost. Standard bulk MOQ is 25kg, and tiered discount prices are available for large long-term orders.

Q4: Can Magnesium Ascorbate be used in organic skincare formulas?

A: This raw material is produced via compliant synthesis processes without harsh synthetic additives, complying with clean-label standards of global organic skincare brands and applicable to natural cosmetic production.
