Zinc sulfate monohydrate
Description
Zinc sulfate monohydrate (CAS 7446-19-7) is an inorganic zinc salt supplied in its stable, single-hydrate crystalline form. It delivers bioavailable zinc across agriculture, nutrition, water treatment, and industrial processing applications.
Consistent zinc content and solubility are critical sourcing requirements for this material. In agriculture and animal feed, it corrects zinc deficiency in soils and livestock diets, improving crop yields and supporting animal health metrics.
Feed formulators rely on this compound to meet specific nutritional targets. Water treatment facilities use it as a coagulation aid and algaecide, controlling biological growth in municipal and industrial water systems.
Pharmaceutical and food manufacturers incorporate it as a zinc fortification source in supplements and oral rehydration formulations. These fortified food products are often subject to FCC or USP specification requirements.
In personal care, it functions as an astringent and antimicrobial active in oral care products, eye drops, and skin formulations. Zinc sulfate monohydrate is supplied as a white crystalline powder or granule.
Granulated forms are preferred in fertilizer blending and feed premix applications for dust control and flowability. Recognized grades include food, pharmaceutical, and technical or agricultural grade options.
Each grade carries distinct purity thresholds relevant to end-use compliance and regulatory standards. Bulk and bagged formats are standard across the global chemical supply chain for industrial buyers.
