Introduction: Why Zinc Sulphate Is Crucial for Modern Formulators
Zinc is one of the most essential trace elements required by the human body—and Zinc Sulphate has become a widely preferred, stable, and soluble form of delivering it through pharmaceutical and nutraceutical formulations. From oral syrups and tablets to injectables and topical creams, zinc sulphate is present across a wide range of finished products aimed at immunity building, wound healing, growth support, and nutrient deficiency correction.
At Vinipul Chemicals Pvt. Ltd., we manufacture and supply high-purity Zinc Sulphate in various forms—monohydrate, heptahydrate, and anhydrous—suitable for human pharmaceutical use, veterinary formulations, and fortified nutrition blends.
With full compliance to FSSAI, ISO, and GMP certifications, and facilities in Mumbai and Taloja, Vinipul supports both domestic pharma giants and global buyers with consistent quality, batch traceability, and export support.
What is Zinc Sulphate?
Chemical Formula: ZnSO₄
Common Forms:
- Zinc Sulphate Monohydrate (ZnSO₄·H₂O)
