Formulation Guide:
1.   Magnesium Ascorbyl Phosphate (MAP) is best used in products with a final formulation pH between 6.0 - 7.0.
2.   The solubility of MAP in water is 154g/l at 25C/77F (that's at most 15.4%)
3.   MAP is stable at 80C/176F for up to 20 hours; thus, 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.
4.   You may also try to pre-disperse it in a small amount of distilled water and add at the end of the formulation process.
5.   You may warm the solution to about 40°C (104°F) to dissolve MAP into solution.
6.   Typical usage rate:  0.2 – 3%, up to 10%
Additional Information:
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 production
