FAQ
Q: How is MAP different from L-Ascorbic Acid and other Vitamin C derivatives like Sodium Ascorbyl Phosphate (SAP) or Ascorbyl Glucoside (AA2G)?
A: MAP offers a unique balance of stability, efficacy, and gentleness. It is more stable than L-AA and effective at a neutral pH, unlike L-AA which requires a low pH. Compared to SAP, which is also stable, MAP is more widely recognized and studied for its skin-brightening effects. AA2G is another stable derivative but works by being slowly converted to Vitamin C by skin enzymes.
Q: How do I incorporate MAP powder into my formulations?
A: MAP is water-soluble. It is best dissolved in the water phase of your formula at room temperature or with slight heating (< 50°C). Ensure it is fully dissolved before proceeding with emulsification.
Q: Is Magnesium Ascorbyl Phosphate safe?
A: Yes, it is considered a very safe and non-irritating ingredient. It is compliant for use in cosmetics in major markets globally, including the EU, USA, China, and Japan.
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 1kg. However, we welcome sample requests and are flexible for long-term partnership discussions.
