Vitamin C - Magnesium Ascorbyl Phosphate (MAP)
CAS No. 113170-55-1

Magnesium Ascorbyl Phosphate is a stable, water soluble derivative of Vitamin C (L-Ascorbic acid mono-dihydrogen phosphate magnesium salt). Unlike L-Ascorbic Acid, it does not readily degrade in formulas containing water.  It is considered light-stable and oxygen-stable. Studies of MAP in aqueous solutions indicate it retains over 95% of its potency at 40°C without any pH adjustment.

By inhibiting tyrosinase activity, MAP is capable of suppressing skin pigmentation, making it effective in whitening dark skin, or areas of dark skin.  It should be noted, one study indicated it might be needed at a concentration of 10% to be effective at inhibiting melanin production1.

Unlike Ascorbyl Palmitate, Magnesium Ascorbyl Phosphate (MAP) appears to have the same potential to boost skin collagen synthesis as does Ascorbic Acid, but at lower concentrations. For those with sensitive skin or those wanting to avoid the exfoliating effects of highly acidic Ascorbic Acid, MAP may be the preferred choice.

Formulation Guidelines

  • Magnesium Ascorbyl Phosphate (MAP) may discolor in formulations with a pH below 6, so is best used in products with a final formulation pH between 6.0 - 7.0.
  • The solubility of MAP in water is 154g/l at 25C/77F (that's at most 15.4%)
  • MAP is stable at 80C/176F for up to 20 hours; this means that it should withstand heating to this temperature for short periods in formulations without a problem.  Therefore, it can be added to the water phase prior to heating.
  • You can also predisperse it in a small amount of distilled water and add at the end of the formulation process.
  • If you're having trouble dissolving MAP in water, warming the solution to about 40°C (104°F) will help.

I just love Lotioncrafter ...they ALWAYS ship your order out immediately without an extra charge like some companies & I once ordered the wrong item & noticed within couple hours they corrected my mistake right away and most other suppliers will not do that. Honestly my favorite supplier. I only go elsewhere if it's something they don't carry (micas,oxides ect..) several times over the past year and half I've been ordering & they are super reliable
Thank you
