Aluminum Hydroxide Magnesium Carbonate Powders

Coprocessed aluminum hydroxide and magnesium carbonate powders for your immediate-relief antacid formulation needs.

Aluminum hydroxide magnesium carbonate (AHMC), Al(OH)3-2x(CO3)x / MgCO3, is a coprocessed active ingredient combining aluminum hydroxide and magnesium carbonate. Our AHMC 0611 grade is specifically designed for rehydration from the powdered form to product a smooth, viscous, nonseparating suspension.


You can choose between our two grades, 0600 and 0652, which vary in assay ratio between aluminum hydroxide and magnesium carbonate to meet your needs for antacid tablets. SPI Pharma can customize the ratio and particle size.
