Description

Magnesium Ascorbyl Phosphate is a stable, water-soluble derivative of Vitamin C (ascorbic acid) where the C-2 hydroxyl group is phosphorylated and neutralized with magnesium. This chemical modification is crucial, as it provides exceptional stability against oxidation, heat, and light compared to pure ascorbic acid, making it highly suitable for formulated products. It is primarily sought after by manufacturers in the cosmetics, personal care, and nutraceutical industries for its proven skin-brightening and antioxidant properties.

Application

• Cosmetic & Skincare Formulations: As a key active ingredient in serums, creams, lotions, and masks for its ability to inhibit melanin production, reduce hyperpigmentation, and provide antioxidant protection against environmental stressors.
• Anti-Aging Products: Used to promote collagen synthesis, improve skin elasticity, and reduce the appearance of fine lines and wrinkles.
• Pharmaceutical & Nutraceutical Preparations: Incorporated into topical pharmaceutical products and dietary supplements as a stable source of Vitamin C activity.
• Hair Care Products: Added to shampoos and conditioners for its antioxidant benefits and potential to improve scalp health.
• Functional Food & Beverage Fortification: Employed as a nutrient stabilizer and antioxidant in select food systems where a non-acidic, stable form of Vitamin C is required.
• Research & Development: Serves as a stable biochemical reagent in laboratory studies related to dermatology, photobiology, and antioxidant mechanisms.

Quality Control

Our Magnesium Ascorbyl Phosphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for cosmetic and personal care applications. A comprehensive Certificate of Analysis (COA) documenting identity, purity, heavy metals, and microbiological limits is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
