Aluminum Hydroxide Gels

At SPI Pharma, we provide a wide range of aluminum hydroxide gels varying in assay and viscosity to meet your formulation needs. We have successfully marketed viscous pastes globally for over 50 years.

Low Viscosity Gels

The low viscosity gels are easy to handle and pumpable with standard equipment. They can be shipped in drums, totes, and bulk container trucks. Due to 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. Our aluminum hydroxide pumpable gels also require less quantity to achieve finished dose, allowing for more concentrated formulations.

LV13 can be used together with our Flogel, magnesium hydroxide pumpable gel, to develop a cost effective antacid suspension with a pleasant mouthfeel. For more information about using Flogel and LV13 together, click below.

High Viscosity Gels

Viscous aluminum hydroxide products, such as Visco 6 and Visco 9, are typically used in regular-strength antacid suspensions. These products yield thick and creamy formulations without requiring the use of additional thickeners or suspending agents. They 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.

Visco 9 can be used with our Type M, magnesium hydroxide paste, to create a cost effective suspension with a pleasant mouthfeel. Click below for more information.
