Food Grade Zinc Sulphate supplied by Nanjing Jiayi Sunway Chemical Co., Ltd. is a colourless to white crystalline powder used in several industrial processes. The product is available as both the monohydrate (ZnSO4·H2O) with a molecular weight of 179.48 g mol‑1 and the heptahydrate (ZnSO4·7H2O) weighing 287.54 g mol‑1. It carries the CAS numbers 7446‑19‑7 for the monohydrate and 7446‑20‑0 for the heptahydrate and dissolves readily in water and glycerol while remaining insoluble in ethanol.
In the food additive market the material is commonly specified with a purity typical > 99 % and a moisture content typical < 0.5 %. The acid hydrometer reading of 1.957 at 25 °C confirms its acidity, and the melting point of about 100 °C indicates stability during handling. Standard industry practice stores the compound in dry, ventilated warehouses to avoid efflorescence, and the material is classified as low‑toxicity when used within regulated limits. The product is supplied in 25 kg polythene‑lined bags placed inside a reinforced plastic woven outer bag, matching common bulk‑shipping formats.
Typical buyers include food additive manufacturers, animal‑feed producers, and firms in printing or timber preservation that require a reliable zinc source. Nanjing Jiayi Sunway lists the packaging as a 25 kg bag, but exact minimum order quantities and lead times must be confirmed directly with the supplier. Prospective importers should also verify storage instructions and any required certifications before finalising a contract.
