Magnesium Ascorbyl Phosphate (MAP)

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.

• MAP is stable in neutral pH, and has no irritation to skin.
• It is usually used in combination with vitamin E for synergistic effect.
• It is most stable in solution and emulsion.
• Excessive use of MAP can interfere with normal enzyme conversion of tyrosine into melanin in skin, which may cause adverse reactions to skin.
