Application

Zinc acetate, with the chemical formula Zn(O2CCH3)2, is a versatile compound primarily existing in the dihydrate form and noted for its colorless, crystalline appearance. It serves multiple purposes, crucially functioning as a dietary supplement to address zinc deficiency, essential for human growth and biological functions such as cholesterol, protein, and fat synthesis. Medically, zinc acetate is administered to treat zinc deficiencies and used in lozenges for common cold relief, being particularly effective compared to other zinc compounds. It also supports Wilson's disease treatment by inhibiting copper absorption and serves in topical formulations for acne and anti-itch ointments. In industrial applications, zinc acetate is employed in wood preservation, production of other zinc salts, polymers, and ethylene acetate, functioning as a dye mordant and analytical reagent, and in the creation of zinc sulfide nanoparticles for advanced applications. Furthermore, it is vital in pharmaceutical formulations, including controlled-release drugs, and has shown potential as a vaginal contraceptive spermicide.
