10g Magnesium Ascorbyl Phosphate Powder (MAP)

Magnesium Ascorbyl Phosphate (MAP) is one of the most stable and skin-friendly derivatives of Vitamin C used in modern cosmetic formulation. Unlike pure L-Ascorbic Acid, which oxidizes quickly and often causes irritation in sensitive skin, MAP was developed to deliver the brightening, antioxidant, and collagen-supporting benefits of Vitamin C in a much gentler and more stable form.

MAP is particularly loved in skincare because it offers excellent performance without the harshness associated with acidic Vitamin C. Once applied to the skin, enzymes gradually convert Magnesium Ascorbyl Phosphate into active Ascorbic Acid, allowing the skin to benefit from Vitamin C in a controlled and less irritating manner.

This ingredient is highly valued in formulations targeting dullness, uneven skin tone, post-inflammatory hyperpigmentation, sun damage, premature aging, and weakened skin barrier. It helps visibly improve skin radiance, reduce the appearance of discoloration, support collagen synthesis, and defend the skin against oxidative stress caused by pollution and UV exposure.

One of MAP’s strongest advantages is its ability to function effectively in higher pH formulations, unlike pure Vitamin C which requires very acidic environments. This gives formulators greater flexibility when creating products such as serums, creams, lotions, emulsions, gel creams, brightening masks, anti-aging treatments, under-eye products, and sensitive skin formulations.

MAP is also widely recognized for helping improve acne-prone skin. Research suggests it may help reduce oxidative damage involved in acne formation while supporting skin recovery and reducing post-acne marks over time.

For brands and formulators seeking a stable, premium brightening active that works across multiple skin types including sensitive skin, Magnesium Ascorbyl Phosphate remains one of the most reliable Vitamin C derivatives available.

INCI Name:

Magnesium Ascorbyl Phosphate

CAS Number:

113170-55-1

Appearance:

White to pale yellow fine powder

Country of Origin:

China

Formation:

Magnesium salt ester of Ascorbic Acid (Vitamin C derivative)

Specification:

• Assay: ≥ 98%
• Purity: Cosmetic/Pharmaceutical grade
• Active Content: High-purity stabilized Vitamin C derivative
• Heavy Metals: Meets cosmetic safety standards
• Microbial Limits: Within acceptable cosmetic specification

Grade:

Cosmetic Grade / Premium Active Ingredient Grade

pH Stability:

Best stability within pH 6.0 – 7.5

Can remain relatively stable in formulations between pH 5.5 – 8.0 depending on formulation system

One of MAP’s biggest formulation advantages is its excellent stability at near-neutral pH, making it significantly easier to formulate with compared to pure L-Ascorbic Acid.

Recommended Usage Percentage:

• 0.2 – 2% → Antioxidant support
• 2 – 5% → Brightening and skin tone enhancement
• 5 – 10% → Intensive pigmentation correction and anti-aging formulations

Typical usage in high-performance skincare: 3 – 5%

Solubility:

Water soluble

MAP dissolves in water phase and requires proper mixing for uniform dispersion. It is not oil soluble.

Compatibility:

Compatible with most skincare actives including:

• Niacinamide
• Hyaluronic Acid
• Panthenol
• Ceramides
• Alpha Arbutin
• Tranexamic Acid
• Licorice Extract
• Peptides
• Green Tea Extract
• Allantoin

Works especially well in brightening and anti-aging systems.

Use caution when combining with ingredients requiring very low pH environments, as this may destabilize MAP.

Mixing Phase & Temperature Range:

Water phase

Recommended incorporation temperature: Below 40°C

For best stability, add during cool-down or low-heat phase after full hydration of water-soluble ingredients. Excessive heat may gradually reduce potency.

Application:

Used in formulation of:

• Brightening serums
• Dark spot correctors
• Anti-aging serums
• Facial creams
• Lotions
• Gel moisturizers
• Under-eye treatments
• After-sun care
• Hyperpigmentation treatments
• Acne recovery products
• Sensitive skin products

Suitable for:

• Dull skin
• Uneven skin tone
• Mature skin
• Pigmented skin
• Sensitive skin
• Acne-prone skin

Performance:

Magnesium Ascorbyl Phosphate delivers multiple high-value skin benefits:

• Helps brighten dull and tired-looking skin
• Supports visible reduction of hyperpigmentation and dark spots
• Improves overall skin radiance and glow
• Encourages collagen production for firmer-looking skin
• Helps reduce visible signs of photoaging
• Provides antioxidant protection against free radical damage
• Supports smoother and healthier-looking skin texture
• Assists in minimizing post-acne marks
• Offers Vitamin C benefits with lower irritation risk

What makes MAP particularly impressive is consistency. Rather than delivering aggressive short-term effects with high irritation, MAP works gradually and reliably to improve skin quality over time, making it ideal for long-term skincare routines.

Storage:

Store in a cool, dry place away from direct sunlight, moisture, and heat.

Keep container tightly sealed to prevent exposure to humidity and air contamination.

Recommended storage temperature: Below 25°C

Shelf Life:

24 months from production date when stored properly in unopened packaging

Precaution:

For external formulation use only.

• Avoid direct inhalation of powder
• Use protective mask when handling large quantities
• Avoid moisture contamination during storage and formulation
• Always perform stability and compatibility testing in final formulation
• Keep away from children
• Not for direct consumption

Although MAP is highly stable compared to many Vitamin C derivatives, final product performance still depends heavily on formulation system, pH balance, packaging, and storage conditions.

From a formulator’s perspective, MAP is one of those ingredients that gives you premium functionality with far less formulation stress. If you want a Vitamin C active that is stable, elegant, effective, and suitable for sensitive skin formulations, this is easily one of the best choices.
