Project Description
Product Description
Zinc sulfate (ZnSO₄) is an inorganic compound typically manufactured through the reaction of sulfuric acid with zinc metal or zinc ores, resulting in a highly soluble, crystalline powder. It serves as a vital source of zinc, an essential trace mineral crucial for immune function, protein synthesis, DNA formation, and cellular metabolism. Widely utilized in dietary supplements to address zinc deficiency, it also finds significant applications in agriculture as a micronutrient fertilizer, in animal feed fortification, and industrial processes like electrolyte for zinc plating and as a mordant in dyeing.

Benefits
- Zinc sulfate corrects zinc deficiencies, strengthening immune response and reducing infection susceptibility.
- It supports skin health by regulating oil production and accelerating wound healing processes.
- This compound is essential for normal growth, development, and reproductive health in children and adults.
- Zinc sulfate aids enzymatic functions critical for DNA synthesis, protein metabolism, and cell division.
Application
- Zinc sulfate is primarily formulated as oral tablets or capsules for human supplementation and is incorporated into animal feed premixes for livestock nutrition; it’s also used in topical solutions for dermatological treatments like acne control.
- In agriculture, it’s applied as a foliar spray or soil additive to prevent zinc-deficient crops; industrially, it acts in water purification, rayon production, and as a laboratory reagent, with dosage guided by specific deficiency levels or process requirements.
