Aluminum hydroxide powder has several applications, primarily in the fields of medicine, industry, and chemistry. Here are the main uses:

1. Antacid in Medicine

Primary Use: Aluminum hydroxide is commonly used as an antacid to neutralize stomach acid and treat conditions like heartburn, indigestion, and gastric ulcers.

How it Works: It reacts with the hydrochloric acid in the stomach to form aluminum chloride and water, helping to reduce acidity.

2. Vaccine Adjuvant

In Vaccines: Aluminum hydroxide is used as an adjuvant in some vaccines. It enhances the body’s immune response to the antigen, making the vaccine more effective.

 3. Water Purification

Flocculant: It is used in water treatment processes to clarify water. Aluminum hydroxide helps remove impurities by forming flocs (clusters of particles) that settle out of the water.

 4. Fire Retardant

Flame Retardant Additive: Aluminum hydroxide is used in various materials, such as plastics, rubber, and textiles, as a flame retardant. When heated, it decomposes to produce water vapor, which helps to suppress fires.

5. Chemistry & Industrial Applications

Precursor to Aluminum Compounds: It is a key intermediate in the production of aluminum metal and other aluminum compounds (such as alumina).

Catalysis and Synthesis: Aluminum hydroxide can be used in chemical reactions as a catalyst or in the synthesis of other chemicals.

6. Cosmetics and Personal Care Products

Skin Care: In some formulations, aluminum hydroxide is used in products like deodorants and as an ingredient in cosmetics. It helps to provide a smoother texture and may also serve as a mild abrasive in exfoliating products.

7. Paper Industry

Filler Material: In the paper industry, aluminum hydroxide is used as a filler material to improve paper quality, enhance opacity, and reduce cost.
