Application
3-1-Dietary and medicinal applications Zinc acetate is used as a dietary supplement and in lozenges used to treat the common cold. Zinc acetate alone is thought to be a more effective treatment than zinc gluconate. Zinc acetate can also be used to treat zinc deficiencies. As an oral daily supplement it is used to inhibit the body's absorption of copper as part of the treatment for Wilson's disease. Zinc acetate is also sold as an astringent in the form of an ointment, a topical lotion; or combined with an antibiotic such as erythromycin for the topical treatment of acne. Furthermore Zinc acetate is commonly sold as a topical anti-itch ointment. 3-2-Industrial applications Industrial applications include wood preserving, manufacturing other zinc salts, polymers, manufacture of ethylene acetate, as a dye mordant, and analytical reagent. Zinc acetate is a precursor via a sol-gel route to the transparent semi conductor zinc oxide.Medicine (astringent), preserving wood, textile
dyeing (mordant and resist), zinc chromate,
laboratory reagent, cross-linking agent for polymers,
ingredient of dietary supplements (up to 1 mg
daily), feed additive, ceramic glazes.Zinc acetate has been used as an excipient in a variety of
pharmaceutical formulations including topical gels, lotions, and
solutions, and subcutaneous injections. It has also been investigated
for use in an oral controlled-release formulation for water-soluble
drugs in combination with sodium alginate and xanthan gum.
Therapeutically, zinc acetate has been used in oral capsules for
the treatment of Wilson's disease. Zinc acetate has also been
demonstrated to be effective as a spermicide in vaginal contraceptives.
Storage
Zinc acetate loses water of hydration above 101°C. Zinc acetate
should be stored in an airtight container in a cool, dry, place.

Physical Description
Obtained in both anhydrous form and as a dihydrate. Both are white crystalline solids. The primary hazard is the threat posed to the environment. Immediate steps should be taken to limit spread to the environment. Used to preserve wood, to make other zinc compounds, as a food and feed additive.;Liquid; OtherSolid; PelletsLargeCrystals;
Stability
