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.

Applications

A car drove off the Anacortes Ferry Dock about 9:45AM this morning and emergency crews are there in a search and recovery effort. Service to and from Orcas Island is expected to be suspended for many more hours. This will delay UPS and Mail shipments by a day as these services will miss connections on the mainland. We appreciate your understanding of this situation beyond our control. Please keep the occupants of the vehicle in your thoughts and prayers. Here's a link to the story: http://www.kiro7.com/news/local/vehicle-plunges-off-anacortes-ferry-dock/689312503

These guys work in timely manner for sure. After I placed my order on Internet they called me in about 15 min because they had some questing about my address. They also made sure that the method of shipment would meet my needs. The little dish that I got was chipped - they sent me the replacement in no time. I haven't yet made any lotions from the ingredients I've got. I will and I'll tell you my opinion soon! Olga

I LOVE Lotioncrafter! First of all you have the ingredients that I need and information on all of those ingredients. Second of all, even though your facility is a LONG way from me in Texas, my order is processed and shipped so fast that I can get my things faster than I can get them from other companies that are much closer to me. I love the rectangular shaped bottles that are used for packaging the ingredients because that shape maximizes my limited storage space. Great quality and great service! Thank you!
Pat Tyson, (Pitterpat Skincare, LLC)

I turned a bright shade of chartreuse, not merely light pink when I received what I ordered. The gifts I received, to make my concocting more pleasurable, were quite a surprise & a delight. I have NEVER received anything free from ANY other skin stuff supplier, even from that big one, the one who name rhymes with Sinew Bidirections!!
I highly recommend this company for our skin concocting needs.
