Zinc Sulfate Heptahydrate

Zinc sulfate heptahydrate is a white to colorless, crystalline solid with no significant odor and low volatility; it decomposes before melting, typically losing water of hydration above 100 °C. It is an inorganic salt and hydrated metal sulfate. Primarily used as a source of bioavailable zinc, it serves as a key intermediate in the production of zinc-based catalysts, pigments (e.g., lithopone), and electrolytes for galvanizing baths. Its main application areas include animal nutrition (feed supplements), agricultural micronutrient fertilizers, and pharmaceutical formulations (e.g., topical antiseptics and dietary supplements).

(1) Zinc sulfate heptahydrate can be used as mordant dyeing, wood preservatives, paper bleaching agent, it can be also used in medicine, synthetic fibers, electrolysis, electroplating, pesticides and production of zinc, etc.(2) It can be used for the preparation of zinc medicine, astringents, etc.(3) It can be used as mordant, wood preservatives, bleach paper industry, it is also used in medicine, synthetic fibers, electrolysis, electroplating, pesticides and production of zinc, etc.(4) Zinc sulfate is zinc supplement of dietary, the component of many enzymes, proteins, such as ribose animals involved in carbohydrate and fat metabolism, and it can catalyze interconversion of pyruvate and lactate, it can promote growth. Zinc deficiency can lead to incomplete keratosis, stunted growth and deterioration of the hair, and it can affect animal reproductive function.(5) Zinc sulfate is allowed to use in food supplements of zinc. China allows to use it in salt, the used of amount is 500mg /kg; in foods for infants and young children is 113~318mg/kg; in dairy products is 130~250mg/kg; in grains and their products is 80~160rag/kg; in liquid and drink milk drinks is 22.5~44mg/kg.(6) It is mainly used for man-made fibers coagulating liquid. In printing and dyeing industry, it is used as mordant, salt-stained blue Lamine alkali agent. It is main raw material of manufacturing inorganic pigments (e.g. lithopone), other zinc salts (e.g. zinc stearate, basic zinc carbonate) and zinc-containing catalyst. It is used as wood preservatives and leather, bone glue clarifying and preserving agents. In pharmaceutical industry, it is used as emetic. It can also be used to prevent diseases and fruit tree nurseries and cable manufacturing zinc fertilizer and so on. It can be used as nutritional supplements (zinc enhancer) and the like in food-grade product.(7) It can be used as analytical reagents, mordant and the phosphor matrix.
