Description

Ascorbic Acid-2-Phosphate Magnesium Salt is a stable, water-soluble derivative of Vitamin C (ascorbic acid). This compound is specifically engineered to overcome the inherent instability of pure ascorbic acid, providing a reliable source of Vitamin C activity in demanding formulations. It is a critical ingredient for manufacturers in the cosmetics, nutraceutical, and pharmaceutical industries seeking enhanced shelf-life and efficacy.

Application

• Cosmetic & Skincare Formulations: As a stable Vitamin C source in anti-aging serums, creams, and lotions for antioxidant protection and collagen synthesis support.
• Nutraceuticals & Dietary Supplements: In tablet, capsule, and powder blends where enhanced stability is required for product shelf-life.
• Pharmaceutical Intermediates: Used in the synthesis of more complex pharmaceutical agents requiring a stabilized ascorbate component.
• Cell Culture Media: As a nutrient component in specialized media for biotechnology and research applications.
• Functional Food & Beverage Fortification: For enriching products with Vitamin C in a form less prone to degradation.
• Aquaculture & Animal Feed Additives: To provide Vitamin C supplementation in feed for improved health and growth.

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) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and humidity. For long-term storage, consider using an inert atmosphere.
