Professional Pharmaceutical-Grade Applications
Different from industrial and food-grade zinc sulfate, our pharmaceutical-grade product features ultra-low impurity content, high biological activity, and excellent safety, making it exclusively suitable for high-standard medical and health fields with strict quality thresholds. The main application scenarios are as follows:
Pharmaceutical Preparations Production
It is a core raw material for manufacturing zinc deficiency treatment drugs, including oral zinc supplementation tablets, capsules, oral solutions, and zinc sulfate injections. As an essential trace element regulator in the human body, it participates in human enzyme synthesis, carbohydrate and fat metabolism, and immune system regulation, widely used in clinical treatment of zinc deficiency-induced growth retardation, oral ulcers, skin inflammation, and immune decline. Its high purity ensures no side impurities interfere with drug efficacy, meeting the strict requirements of pharmaceutical sterile preparations.
Nutraceutical & Dietary Supplement Raw Materials
Widely used in high-end human nutritional supplements, infant formula additives, and functional health products. It serves as a safe and efficient zinc fortifier, helping users supplement daily required zinc elements, improve physical development, and enhance body immunity. Strict impurity control ensures compliance with international food and drug safety regulations, suitable for long-term human intake.
Medical Topical Preparations
With excellent astringent and antibacterial properties, pharmaceutical-grade zinc sulfate heptahydrate is used in the production of medical topical ointments, lotions, and eye drops. It can relieve skin inflammation, inhibit bacterial growth, and protect mucosal tissues, commonly applied in dermatological and ophthalmic medical preparations.
Biochemical Research & Laboratory Reagents
It is a high-purity analytical reagent for biochemical laboratories, used for enzyme research, microbial culture, and pharmaceutical component testing. Its stable chemical properties and ultra-high purity ensure accurate and reliable experimental data, supporting pharmaceutical research and new drug development projects worldwide.
Our Core Competitive Advantages
