What is aluminum hydroxide

The most important use of aluminum hydroxide is as an antacid. It is commonly found in over-the-counter antacid medications because it can neutralize excess stomach acid and relieve symptoms of heartburn, indigestion, and upset stomach. Its ability to neutralize acid is due to its property to form aluminum chloride and water by reacting with hydrochloric acid in the stomach.

Additionally, aluminum hydroxide has other applications, including:

  • Flame Retardant: It is used as a flame retardant in various materials such as plastics, textiles and coatings to reduce the flammability of these materials.

  • Water Treatment: Aluminum hydroxide is used in water treatment processes to remove impurities and clarify water.

  • Pharmaceuticals: It can be used as an adjuvant in some vaccines to enhance the body's immune response to antigens.

  • Filler in Paper and Plastic: It is used as filler in the manufacturing of paper, plastic and rubber products to improve their properties.

  • Abrasive Ingredients: In some abrasive products, aluminum hydroxide may be used as an abrasive ingredient.

It is important to note that while aluminum hydroxide is generally considered safe for its intended use, excessive consumption of aluminum compounds can be harmful to human health and has been linked to some neurological disorders. Therefore, it is essential to follow recommended dosage guidelines and consult a health care professional when using products containing aluminum hydroxide.
