a) Stable and Water Soluble Vitamin C Derivative
b) Skin Lightening
MAP SL (Magnesium ascorbyl phosphate ) is a stable, water soluble vitamin C derivative. Vitamin C has been well-known for its inhibitory effects on melanin formation, but it has not been widely used for this function due to its instability in formulations. A number of vitamin C derivatives such as ascorbyl palmitate or ascorbyl stearate, have been used for 20 years as primary depigmenting materials, however, these conventional vitamin C derivatives can destabilize formulations, and magnesium ascorbyl phosphate now replaces other ascorbates in most products.
Water Solubility: MAP SL is completely water soluble and easily absorbed through the skin. Its water-solubility offers the formulator with formulating flexibility.
Stability: MAP SL is much more stable to heat and light than vitamin C. Experimental data showed that 3% aqueous solution of MAP SL maintained 90% of its activity after 6 months of storage in 40 water bath.
Skin Lightening/Beatifying Effects: MAP SL exhibits a strong skin lightening effects which was shown useful in clinical practice. It has strong inhibitory effects on melanin formation therefore resulting in beautified, even-toned skin.
Radical Scavenger: Once absorbed into the skin, MAP SL can act as a radical scavenger to eliminate radicals and remove the signs of wrinkles and aging.
Synergistic with Vitamin E: MAP SL works synergistically with Vitamin E. Stable Formulation: Unlike other skin lightening agents such as hydroquinone, MAP SL is stable without color change problems.
Safety: MAP SL is very safe with no toxicity and irritation.
Application: All cosmetic and personal care products.
Use Levels: Creams: 1~10%; Lotions: 0.5~3%.
