Zinc acetate

Zinc acetate is a chemical compound with the formula Zn(CH₃COO)₂. It is used in various applications, including as a dietary supplement, in the treatment of the common cold, and in manufacturing processes. Zinc acetate can exist in anhydrous form or as a dihydrate.

Chemical Properties

Zinc acetate is a salt formed by the reaction of zinc oxide with acetic acid. It is a white solid that is soluble in water, ethanol, and acetone. The anhydrous form has a melting point of 237°C, while the dihydrate melts at 100°C and decomposes at 237°C.

Medical Uses

Zinc acetate is used in medical applications primarily for its ability to release zinc ions. Zinc is an essential trace element necessary for the proper function of the immune system, wound healing, and DNA synthesis.

Dietary Supplement

As a dietary supplement, zinc acetate is used to prevent or treat zinc deficiency. Zinc plays a vital role in numerous biochemical processes and is essential for normal growth and development.

Common Cold

Zinc acetate lozenges are used to reduce the duration of the common cold. Studies suggest that zinc lozenges may lessen the severity and length of cold symptoms when taken within 24 hours of the first symptoms.

Wilson's Disease

Zinc acetate is also prescribed for the treatment of Wilson's disease, a rare genetic disorder that causes copper accumulation in the body. Zinc acetate works by inhibiting the absorption of copper in the intestine.

Industrial Uses

In industry, zinc acetate is used as a catalyst in the production of polyesters, as a dye mordant, and in wood preservation. It also serves as a source of zinc in various chemical syntheses.

Safety

While zinc acetate is generally considered safe when used as directed, excessive intake can lead to zinc toxicity, symptoms of which may include nausea, vomiting, loss of appetite, abdominal cramps, diarrhea, and headaches. Long-term high intake of zinc can interfere with copper absorption, potentially leading to copper deficiency.
