5100 is free flowing and blends very well with other ingredients. It is low lead (<125 ppb) and can be used in antacids that must meet USA’s California Proposition 65.

5112 is free flowing and blends very well with other ingredients. With its larger particle size it is ideally used in directly compressible antacid or laxative tablets. Nominal particle size is between 150 and 850µm.

5200 is a medium-density product specifically designed for rehydration from the powdered form to product a smooth, viscous, nonseparating suspension. This is required for milk of magnesia (MoM) laxative systems. It is cost-effective for shipment anywhere in the world since it eliminates the cost of shipping water.

5300 is a dense powder that conforms to both USP and EP standards.
