Aluminum Hydroxide Gels

At SPI PharmaTM, we provide a wide range of aluminum hydroxide gels varying in assay and viscosity to meet your formulation needs.

Viscous aluminum hydroxide products are typically used in regular-strength antacid suspensions. The products provide the appropriate thickness without requiring the use of gums or suspending agents. These gels can be dumped from drums with suitable equipment or pumped from the drum with specially designed pumps.






Visco 6
has the same advantages as Visco 9, but is easier to transfer because it is pumpable. It can be delivered in drums, totes, and even bulk container trucks.

The low viscosity gels are pumpable with standard equipment and can be shipped in drums, totes, and bulk container trucks. Because of the lower viscosity upon dilution to final formulation, the use of suspending agents and thickeners are recommended to achieve appropriate thickness for an antacid suspension.
