Chemical structure and physical properties of Magnesium Ascorbyl Phosphate

Magnesium Ascorbyl Phosphate (MAP) is a water-soluble derivative of Vitamin C (ascorbic acid) that is commonly used in skincare products due to its stability and potential skin benefits. It is a white or off-white powder with the chemical formula C12H12MgO18P3 and a molecular weight of approximately 422.98 g/mol.

Here are some key details about the chemical structure and physical properties of Magnesium Ascorbyl Phosphate:

Chemical Structure:

  • Molecular Formula: C12H12MgO18P3
  • Chemical Name: Magnesium 2-phospho-L-ascorbate
  • CAS Number: 113170-55-1
  • Magnesium Ascorbyl Phosphate is a salt of ascorbic acid (Vitamin C) and contains a phosphate group (PO4) and a magnesium ion (Mg2+) bound to the ascorbic acid molecule.

Physical Properties:

1.Appearance: Magnesium Ascorbyl Phosphate typically appears as a white to off-white powder or crystalline solid.

2.Solubility: It is water-soluble, which makes it suitable for use in water-based skincare products. This solubility is one of the advantages of using MAP in skincare formulations, as it allows for better skin absorption.

3.Stability: Unlike pure ascorbic acid, which can be unstable and degrade easily in the presence of air and light, Magnesium Ascorbyl Phosphate is more stable. It is less prone to oxidation, which is a common issue with vitamin C in skincare products.

4.pH Sensitivity: Magnesium Ascorbyl Phosphate is stable at a wider pH range compared to ascorbic acid, making it suitable for formulations with varying pH levels, such as many skincare products.

5.Skin Benefits: Magnesium Ascorbyl Phosphate is used in skincare for its potential benefits, including its ability to promote collagen production, reduce the appearance of fine lines and wrinkles, and brighten the skin. It is also known for its antioxidant properties, which help protect the skin from damage caused by free radicals.

6.Skin Compatibility: Magnesium Ascorbyl Phosphate is generally considered to be well-tolerated by most skin types, including sensitive skin, because it is less likely to cause irritation than some other forms of vitamin C.

7.Usage: In skincare products, Magnesium Ascorbyl Phosphate is typically used at concentrations ranging from 1% to 10% or more, depending on the product and its intended purpose.

It’s important to note that the effectiveness of skincare products containing Magnesium Ascorbyl Phosphate can vary depending on the formulation, concentration, and other ingredients used. As with any skincare product, it’s advisable to perform a patch test and consult with a dermatologist or skincare professional if you have specific skin concerns or conditions.
