Magnesium Ascorbyl Phosphate Powder (MAP) - Stable Vitamin C for DIY Skincare - 28 g (1 oz)

Key Benefits of MAP for Skincare

Magnesium ascorbyl phosphate (MAP) is a stabilized derivative of vitamin C that offers hydration and antioxidant protection without the instability of L-ascorbic acid. Its near-neutral pH makes it gentle on sensitive skin, and the magnesium component helps soothe and calm. MAP supports the skin's natural radiance and resilience, and it works harmoniously with niacinamide—perfect for brightening formulations.

• Stable Form: Resists oxidation, extending the shelf life of your DIY creations.
• Hydration Support: Helps maintain moisture balance in the skin.
• Compatible with Niacinamide: Both ingredients share a similar pH, so you can combine them without losing efficacy.

What Is Magnesium Ascorbyl Phosphate (MAP)?

If you're into DIY skincare, you've likely come across MAP—a stable form of vitamin C that won't break down in water-based formulas. Unlike L-ascorbic acid, MAP remains active and effective, making it a go-to for creating customised serums, creams, and lotions at home. Talsen Chemicals offers high-purity MAP in a convenient 28-gram (1-ounce) resealable pouch.

Why Choose Talsen Chemicals MAP Powder?

Talsen Chemicals provides a pure, finely milled powder that dissolves easily without clumping. Each batch is sealed in a pouch to keep out moisture. DIY enthusiasts appreciate the consistent quality and reliability of this ingredient for their skincare creations. Many users have left positive feedback, praising the powder's performance in their own formulations.

How to Use MAP Powder in DIY Formulations

MAP is water-soluble, so you can add it directly to your favourite bases. The typical recommended usage rate is 1–3% of the total formula weight. For a 100-gram serum, that means 1 to 3 grams of MAP powder. Dissolve it in distilled water or hydrosol before mixing with other ingredients. It works well in serums, toners, and lightweight lotions. To boost hydration, combine it with hyaluronic acid; for brightening, pair it with niacinamide. Always use a precision scale, sanitize your equipment, and perform a patch test before widespread use.
