Dissolving Magnesium Ascorbyl Phosphate (MAP) at High Concentrations

Regarding dissolving Magnesium Ascorbyl Phosphate (MAP) at concentrations exceeding 8%, the product information indicates that while MAP is water-soluble, using concentrations above 8% may cause problems with dissolution.

Magnesium Ascorbyl Phosphate is stable in formulas with a pH range of 7-9. Maintaining this pH is crucial for its stability.

The suggestion to use Sodium Citrate is relevant because Sodium Citrate acts as a pH buffer. Using a buffer like Sodium Citrate can help maintain the optimal pH range of 7-9 for MAP stability, which is important for keeping it dissolved once it is in solution within its solubility limit.

However, based on the available product information, while Sodium Citrate can assist with pH stability, it does not explicitly state that it increases the solubility limit of MAP beyond the indicated potential issue at concentrations exceeding 8%. The product description highlights the potential for dissolution problems at higher concentrations and does not detail specific methods or co-solvents to significantly increase its solubility beyond this point.
