Zinc sulfate

Zinc sulfate is an inorganic chemical compound with the formula ZnSO4 (O4SZn) and CAS number 7733-02-0. It has a molecular weight of 161.4 g/mol and appears as white crystalline powder or granules. This versatile zinc salt is widely used in industrial applications and is classified as a hazardous substance requiring proper handling due to its acute toxicity and environmental impact on aquatic life.

Zinc sulfate is a white crystalline solid that is highly soluble in water, forming acidic solutions. It is odorless and has a molecular weight of 161.4 g/mol. The compound is hygroscopic, meaning it readily absorbs moisture from air. It decomposes at high temperatures and is incompatible with strong bases. Its high water solubility makes it readily bioavailable, contributing to both its effectiveness and environmental concerns.

Zinc sulfate is used primarily as a zinc supplement in animal feed, fertilizer production, and pharmaceutical applications. It serves as a micronutrient in agriculture to prevent zinc deficiency in crops and soil. Industrial applications include use in galvanizing processes, wood preservation, and as a mordant in textile dyeing. It's also utilized in the production of other zinc compounds and in water treatment processes.

Zinc sulfate requires careful handling due to its Acute Tox. 4 and Eye Dam. 1 classifications. Wear appropriate PPE including safety goggles, gloves, and protective clothing to prevent skin and eye contact. Ensure adequate ventilation to avoid dust inhalation. Avoid generating dust clouds and keep away from water sources due to its high aquatic toxicity. Always follow GHS07, GHS05, and GHS09 pictogram warnings during handling operations.

Zinc sulfate should be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and alkalis. Keep containers tightly sealed to prevent moisture absorption due to its hygroscopic nature. Store away from water sources and drainage systems due to its high aquatic toxicity (Aquatic Acute 1, Aquatic Chronic 1). Ensure storage areas have appropriate spill containment measures and restricted access.

Zinc sulfate contact requires immediate action due to its Eye Dam. 1 classification. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air and seek medical attention if symptoms persist. In case of ingestion, rinse mouth and seek immediate medical advice. Never induce vomiting.

Zinc sulfate disposal must comply with local and European waste regulations due to its environmental hazard classification. It cannot be disposed of in regular waste streams due to its aquatic toxicity. Contact licensed waste disposal companies for proper treatment and disposal. Small quantities should be collected and treated as hazardous waste. Never discharge into water systems, soil, or sewage systems due to severe environmental impact.

Zinc sulfate is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transport purposes. It requires appropriate UN-approved packaging and hazard labeling during transportation. Transport vehicles must carry proper documentation and emergency procedures. Drivers need ADR training for Class 9 materials. Ensure packages are properly sealed and labeled with GHS pictograms (GHS07, GHS05, GHS09) and transport information.

Zinc sulfate is regulated under European REACH and CLP regulations due to its hazardous properties. It carries the signal word 'Danger' and requires safety data sheets for commercial distribution. While not classified as SVHC (Substance of Very High Concern), its aquatic toxicity makes it subject to environmental protection regulations. Industrial users must comply with occupational exposure limits and environmental discharge restrictions under various EU directives.

Zinc sulfate is available through OYSI, a specialized European distributor of technical chemicals. OYSI provides high-quality zinc sulfate with proper documentation including safety data sheets, certificates of analysis, and regulatory compliance information. As an established chemical distributor, OYSI ensures reliable supply chains across Europe with appropriate packaging, labeling, and transport arrangements meeting all ADR Class 9 requirements and European chemical regulations.
