Overview
Magnesium Ascorbyl Phosphate (MAP) is a stable, water-soluble derivative of Vitamin C widely used in skin brightening and anti-aging formulations. MAP remains stable in water-based systems and helps reduce discoloration caused by UV exposure, post-inflammatory hyperpigmentation, and uneven skin tone.

Key Features
Assay Purity Standard: Guaranteed minimum of 98.5% active MAP on an anhydrous basis, verified via multi-stage crystallization to minimize batch-to-batch performance variation.
Formulation pH Stability: Functions within a stable pH range of 6.0 to 7.5, reducing oxidation, browning, and degradation risks commonly associated with low-pH Vitamin C derivatives.
Cold-Water Solubility: Dissolves cleanly in water at room temperature up to 150 g/L, helping formulators achieve clear, sediment-free liquid systems.
Dermo-Cosmetic Compatibility: Features a low-irritation profile compared to traditional Ascorbic Acid, making it suitable for sensitive skin formulations at use levels between 0.5% and 3.0%.
Targeted Biological Delivery: Gradually converts to active L-Ascorbic Acid within the skin, supporting a measured 42% reduction in tyrosinase activity in laboratory testing.
Application Recommendations
High-Performance Serums: Used as a primary brightening active in daily radiance and spot-correcting treatments.
Brightening Creams & Lotions: Provides stable skin-tone-evening performance in moisturizers and overnight repair products.
Under-Eye Care Products: Suitable for dark-circle treatments due to its low-irritation characteristics around delicate skin areas.
Anti-Aging Fluid Systems: Incorporated into antioxidant-focused formulations designed to combat environmental stress.
Sheet Masks & Treatment Patches: Dissolves completely in water-based essence systems without affecting product clarity.
Post-Sun Recovery Products: Used in after-sun formulations to help address UV-induced oxidative stress.
Manufacturing & Quality Control
600-Metric Ton Annual Capacity: Automated production lines support consistent supply for both regional and global brand owners.
In-House Analytical Verification: Product purity is verified using Agilent 1260 Infinity II HPLC systems, while heavy metals are monitored through ICP-MS analysis.
Contamination & Impurity Control: Magnetic filtration and controlled drying processes help minimize foreign particles and maintain free phosphate levels below specification limits.
Raw Material Identity Verification: Incoming raw materials undergo FTIR fingerprint analysis before entering production.
Third-Party Compliance Audits: Manufacturing facilities are periodically audited by independent inspection organizations such as SGS and Intertek.
