Aluminum Compounds

Aluminum hydroxide is a typical antacid active. It can be used alone or in combination with magnesium hydroxide to obtain the desired acid neutralizing capacity (ANC). Aluminum hydroxide as an antacid is not exactly an aluminum hydroxide (Al(OH)3). Aluminum hydroxide gels are amorphous in nature and contain carbonate in the gel structure. The presence of carbonate increases the reactivity of the aluminum, allowing for its acid-neutralizing capacity and making it a more effective antacid.

We provide a wide range of aluminum hydroxide gels varying in assay and viscosity to meet your antacid suspension formulation needs. Whether producing by wet granulation or direct compression process, we also offer a portfolio of aluminum powders varying in density and particle size distribution to meet your antacid tablet requirements. The aluminum assay for powders is not less than 76.5% on an Al(OH)₃ basis or not less than 50% on an Al₂O₃ basis.
