Description

Magnesium Ascorbyl Phosphate (MAP) is a water-based, stable vitamin C derivative used to support a more even-looking complexion and healthier-looking skin over time. It is commonly chosen when you want vitamin C benefits but prefer a formula that is less reactive than pure L-ascorbic acid.
MAP helps improve the look of dullness and uneven tone, and it is also valued for antioxidant support, which helps reduce the visible impact of everyday environmental stressors on the skin.
Because MAP performs best in a slightly higher pH range than L-ascorbic acid, it fits well in gentle brightening serums, moisturizers, and emulsions designed for consistent daily use.

FEATURES

Stable vitamin C derivative – easier to formulate than pure ascorbic acid for many product types.
Even-tone support – helps reduce the look of dark spots and uneven tone over time.
Antioxidant support – helps protect skin appearance against environmental stress.
Gentler approach – often preferred for users who struggle with low-pH vitamin C products.

BEST FOR

Brightening serums
Dark spot support
Daily moisturizers
Even-tone body lotions
Antioxidant gels
Gentle vitamin C routines

Formulator tip: MAP likes a slightly higher pH than pure vitamin C. Target around pH 6.0–7.0 for best stability and performance, and include a chelator to reduce oxidation risk.

FORMULATION GUIDELINES

INCI	Magnesium Ascorbyl Phosphate
Type	Vitamin C derivative (brightening and antioxidant active)
Solubility	Water soluble (best in warm water with mixing)
Use Rate	1.0–10.0% typical. 3.0–5.0% is a common range for visible brightening support in daily leave-on products.
Best Phase	Water phase or cool-down (recommended if your system is heat sensitive)
pH Compatibility	Best stability is typically around pH 6.0–7.0. Avoid very low pH systems.
Temperature Tolerance	Generally tolerates moderate heat, but we recommend adding below 40–50°C when possible to reduce stress and protect other actives.
Pro Tip	MAP can be slow to dissolve. Pre-disperse in a portion of water (or a water + humectant blend), mix until fully uniform, then add to batch. Use a chelator (for example, disodium EDTA or sodium phytate) and minimize metal contact to reduce discoloration risk. Check pH immediately after batching, then again after 24 hours because some systems drift.
Appearance	White to off-white powder
Stability Notes	Stability depends strongly on pH and metal ions. Keep pH in range and include a chelator for better color control.
Storage	Store tightly closed in a cool, dry place away from heat and moisture.
