Usage and Applications:

Aluminum hydroxide, also known as alumina trihydrate, is a chemical compound with various applications across different sectors. This article provides a comprehensive overview of the applications and uses of aluminum hydroxide in diverse industries. From pharmaceuticals and cosmetics to water treatment and flame retardants, aluminum hydroxide plays a vital role in enhancing processes, improving products, and promoting safety.

  1. Pharmaceutical and Medical Applications:

1.1 Antacid and Anti-Ulcer Medications: Aluminum hydroxide is widely used as an antacid and anti-ulcer medication. It neutralizes excess stomach acid, providing relief from heartburn, indigestion, and gastric ulcers. Aluminum hydroxide can also act as a protective coating on the gastrointestinal lining.

1.2 Phosphate Binder in Kidney Disease: In patients with kidney disease, aluminum hydroxide acts as a phosphate binder. It binds to dietary phosphate in the gastrointestinal tract, reducing its absorption and helping to manage elevated phosphate levels in the blood.

1.3 Vaccine Adjuvant: Aluminum hydroxide is utilized as a vaccine adjuvant, enhancing the immune response to vaccines. It helps stimulate the production of antibodies and boosts the effectiveness of vaccines against infectious diseases.

  1. Cosmetics and Personal Care:

2.1 Antiperspirants: Aluminum hydroxide is a common ingredient in antiperspirant products. It helps reduce perspiration by forming a temporary plug-in sweat duct, thereby providing long-lasting odor and wetness protection.

2.2 Sunscreen and Sunblock: Aluminum hydroxide is used in sunscreens and sunblock formulations. It helps disperse and stabilize the active ingredients, providing protection against harmful UV radiation and minimizing the risk of sunburn and skin damage.

2.3 Skin Care Products: Aluminum hydroxide is employed in various skin care products such as lotions, creams, and masks. It functions as a thickening agent, improving product consistency and texture. Additionally, it can have soothing properties and help calm irritated skin.

  1. Water Treatment:

3.1 Coagulation and Flocculation: Aluminum hydroxide is used in water treatment processes for coagulation and flocculation. It aids in the removal of suspended particles, organic matter, and turbidity, facilitating the purification of drinking water and wastewater treatment.

3.2 pH Adjustment: Aluminum hydroxide can be used to adjust the pH levels of water. It acts as a pH stabilizer, preventing fluctuations and maintaining optimal conditions for various water treatment processes.

  1. Flame Retardants:

4.1 Fire-Resistant Materials: Aluminum hydroxide is employed as a flame retardant in various materials. It releases water vapor when exposed to heat, effectively cooling the material and suppressing the spread of flames. This property makes it valuable in the manufacturing of fire-resistant coatings, textiles, and plastics.

4.2 Construction and Building Materials: Aluminum hydroxide is used in construction and building materials to enhance their fire resistance. It can be incorporated into paints, sealants, and insulation materials, providing added safety in residential and commercial structures.

  1. Ceramics and Glass:

5.1 Ceramic Fillers and Reinforcements: Aluminum hydroxide serves as a filler and reinforcement agent in ceramic materials. It improves the mechanical strength, thermal stability, and resistance to cracking of ceramics, making them suitable for applications in electrical insulators, refractory materials, and abrasives.

5.2 Glass Manufacturing: In the glass industry, aluminum hydroxide acts as a flux and opacifier. It reduces the melting temperature of glass and imparts opacity, enhancing the aesthetic appeal of glass products.

  1. Other Applications:

6.1 Catalyst Support: Aluminum hydroxide is used as catalyst support in various chemical reactions. It provides a high surface area for catalysts, improving their efficiency and promoting desired chemical transformations.

6.2 Abrasive and Polishing Compounds: Aluminum hydroxide can be utilized as an abrasive and polishing agent. It is incorporated into compounds used for metal polishing, lens grinding, and precision machining, ensuring smooth surfaces and high-quality finishes.

6.3 Paints and Coatings: Aluminum hydroxide is employed in the formulation of paints and coatings. It acts as an extender pigment, improving opacity, color retention, and corrosion resistance in protective coatings for metal surfaces.


Aluminum hydroxide, with its versatile applications and uses in various sectors, plays a significant role in enhancing processes, improving products, and promoting safety. From pharmaceuticals and cosmetics to water treatment and flame retardants, aluminum hydroxide demonstrates its value and versatility. As industries continue to advance, the demand for aluminum hydroxide is expected to grow, contributing to further innovations and developments across different sectors.
