MAP is a fine white/ivory fluffy WATER SOLUBLE powder. highly popular antioxidant and is a required component in the production of collagen, the tissue responsible for skin suppleness. Vitamin C has also been shown to help slow the production of age spots and provides some UV protection.
There are quite a few water soluble vitamin C products available for formulators : this is our most expensive one - and, of the water soluble ones, the most stable in oxidating conditions.
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.
Many commentators argue that Magnesium Ascorbyl Phosphate (MAP) has the same potential to boost skin collagen synthesis as does Ascorbic Acid ( which will start to yellow as soon as you have finished making your product), but at lower concentrations.
For those with sensitive skin or those wanting to avoid the exfoliating effects of highly acidic Ascorbic Acid, MAP is our recommendation
Useage 1%- 10% in water phase. We've tried formulating with up to 15% but reckon you should max out at about 10% (15% is about its maximum solubility in water)
Efficacy is significantly reduced in formulations with pH below 6.0 - you might also see some discolouration.
If you're having trouble dissolving it - heat your water to about 40 deg C and re-try.
