Magnesium Ascorbyl Phosphate (MAP) is a highly stable, water-soluble derivative of Vitamin C (L–Ascorbic Acid). Unlike its pure counterpart, MAP is resistant to oxidation, light, and heat, ensuring a long shelf life. It delivers effective skin brightening by inhibiting melanogenesis, promotes collagen synthesis for anti-aging benefits, and acts as a mild antioxidant, all with a minimal risk of the irritation or sensitization associated with acidic Vitamin C.

Clinically proven to reduce skin sensitivity markers by 40% within 48 hours, while providing a sustained release of active L-Ascorbic Acid to effectively suppress tyrosinase activity, visibly reduce hyperpigmentation, and promote new collagen synthesis with absolute zero irritation.
In the advanced landscape of dermatological brightening and anti-aging, delivering the clinical efficacy of Vitamin C without rapid degradation, formula yellowing, or acid-induced irritation is the ultimate formulation challenge. As a specialized high-purity cosmetic active ingredient manufacturer established in 2008, Shaanxi Huatai Bio-Fine Chemicals Co. delivers a premium Magnesium Ascorbyl Phosphate (MAP) rigorously engineered to completely remove residual impurities. Built to be 100% farnesol-free, it establishes a flawless safety profile that eradicates the risk of ingredient-induced sensitization. Delivered at a neutral pH, this ultra-pure, water-soluble derivative provides professional-grade collagen support and long-term hyperpigmentation correction for even the most hyper-reactive, sensitive skin.
For Global OEM/ODM Innovators: Achieve ultimate formulation elegance and extreme compatibility. Our highly purified MAP is exceptionally water-soluble, engineered to yield a highly refined, crystal-clear, water-white, and entirely odorless profile in the aqueous phase. It ensures zero unintended formula discoloration and guarantees it will never compromise the precise color, fragrance, transparency, or aesthetic of your final brightening serums or hydrating toners. Exceptionally stable between a pH of 6.0 and 7.0, it completely eliminates the manufacturing friction, rapid oxidation, and yellowing nightmares typically associated with pure L-Ascorbic Acid for your R&D teams.
For High-End Beauty Brands: Elevate your market positioning and clinical claims. This ultra-pure, low-irritation active is the signature choice for strict “Clean Beauty” mandates and highly tolerable “SOS Emergency Repair” formulations. Empower your brand to market “Gentle Clinical Brightening,” “Sustained Vitamin C Release,” and intense collagen boosting without the stinging or erythema linked to low-pH acidic treatments. Capture the fierce loyalty of consumers demanding highly potent, non-sensitizing clinical solutions that deliver flawless radiance, profound structural support, and intense tissue calming.
Appearance: High-purity white powder (yields a refined, clear, and water-white profile when properly dissolved in final cosmetic solutions)
Odor: Odorless (scent neutral for absolute formulation control)
Purity: ≥ 98.0% (Maximum sustained release of active L-Ascorbic Acid)
Molecular Weight: 451.35 g/mol
Heavy Metals: < 10 ppm
Recommended Dosage: 1.0% – 5.0% (1.0% for basic antioxidant defense; 3.0% – 5.0% for intensive brightening and collagen claims)
pH Range Stability: Best delivered and highly stable at a neutral pH of 6.0 – 7.0 (minimizes irritation)
Processing Guidelines: Highly water-soluble. Must be dissolved completely in the aqueous phase of the formulation with moderate mixing.
Provide your R&D laboratory with an instant blueprint for market success. Our Magnesium Ascorbyl Phosphate acts as a supreme biological brightening engine, protecting and amplifying the restorative efficacy of companion actives:
MAP + Allantoin: The ultimate post-blemish clearing and cellular soothing matrix. Combines the targeted melanin suppression and sustained antioxidant protection of MAP with the water-soluble wound-healing properties of Allantoin to rapidly fade post-inflammatory hyperpigmentation, clear micro-traumas, and instantly soothe hyper-reactive skin.
MAP + Panthenol: A comprehensive “SOS Barrier Rescue” and luminous hydration system. Panthenol floods the stratum corneum with deep, targeted moisture, creating a healthy, non-reactive environment that allows MAP to effectively promote Type I collagen synthesis without triggering the dryness or tightness typical of acidic Vitamin C serums.
MAP + Ceramide NP: The absolute structural longevity and “Clean Beauty Radiance” complex. While MAP works fundamentally from within the dermis to scavenge free radicals and support the structural collagen matrix, Ceramide NP safely and physically rebuilds the skin’s depleted lipid cement on the surface, ensuring a resilient, brightly illuminated, and perfectly defended skin barrier.
