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 got my products very fast and overall I am very satisfied with Lotioncrafter's service. I was surprised that they included extra measuring utensils in the box! I WILL be ordering from Lotioncrafter again.

Nancy Babbs, (Bellevue Organics)

Jen, I have been wanting to say thank you in a very special way for a long time. I have been trying to switch as much of my business over to your shop as possible. Everyone talks about your fabulous customer service. But what I am most impressed about it how smart you are and the wide variety or products you have available for the small business, The quality of research you have posted on your site is not available anywhere else. Whenever I have a very difficult formulating problem to solve I come to your site. None of my other suppliers (many of whom I spend 100's of dollar a month with) can answer even simple questions. You have gotten back to me within minutes with very educated answers and suggestions. I feel like you have given me tools, resources, and base ingredients to really blossom. I am so grateful.
