Aluminum Chloride: Properties, Uses, and Side Effects

Aluminum chloride is a chemical compound that is widely used in various industrial and medical applications. In this article, we will discuss the properties, uses, and potential side effects of aluminum chloride.

Introduction

Aluminum chloride is a white to yellowish crystalline solid that is highly soluble in water. It is a versatile compound that has a wide range of applications in various industries, including water treatment, pharmaceuticals, and cosmetics. However, like any chemical compound, aluminum chloride can also have side effects. In this article, we will discuss the properties, uses, and potential side effects of aluminum chloride.

What is Aluminum Chloride?

Aluminum chloride is a chemical compound with the formula AlCl3. It is a strong Lewis acid and is commonly used as a catalyst in organic chemical reactions. Aluminum chloride can exist in various forms, including anhydrous and hydrated forms. The anhydrous form is a white powder, while the hydrated form is a yellowish or greenish crystal.

Properties of Aluminum Chloride

Aluminum chloride is a highly reactive compound that is soluble in water and polar solvents. Its melting point is 190.7°C, and its boiling point is 180.8°C. It has a high affinity for water, and when it comes in contact with water, it can generate hydrogen chloride gas. Aluminum chloride is also hygroscopic, meaning it can absorb water from the air.

Uses of Aluminum Chloride

Aluminum chloride has a wide range of applications in various industries. Some of its common uses are:

Aluminum Chloride in Water Treatment

Aluminum chloride is commonly used in water treatment plants to remove impurities such as suspended solids, color, and organic matter. It works by forming a floc with the impurities, which can then be easily removed through sedimentation or filtration.

Aluminum Chloride in the Pharmaceutical Industry

Aluminum chloride is used as an active ingredient in antiperspirants to reduce sweating. It is also used in the production of vaccines and as a hemostatic agent in surgical procedures.

Aluminum Chloride in Cosmetics

Aluminum chloride is used in cosmetics as an astringent to tighten the skin and reduce pore size. It is also used in skin lightening creams to reduce the production of melanin, which can cause hyperpigmentation.

Side Effects of Aluminum Chloride

While aluminum chloride is generally considered safe when used as directed, it can cause side effects in some people. Some of the common side effects of aluminum chloride include:

• Skin irritation and redness
• Itching and burning sensation
• Swelling and rash
• Allergic reactions

Safety Precautions When Using Aluminum Chloride

To avoid any potential side effects, it is essential to follow the safety precautions when using aluminum chloride. Some of the safety precautions are:

• Wear protective clothing, including gloves and goggles, when handling aluminum chloride.
• Use aluminum chloride in a well-ventilated area.
• Do not ingest aluminum chloride.
• Do not apply aluminum chloride to broken or irritated skin.
• Keep aluminum chloride out of reach of children.

Conclusion

Aluminum chloride is a versatile compound that has a wide range of applications in various industries, including water treatment, pharmaceuticals, and cosmetics. While it is generally considered safe when used as directed.
