Description
Zinc sulfate (ZnSO₄, CAS 7733-02-0) is an inorganic zinc salt also known as zinc vitriol or white vitriol, supplied here in liquid form. It carries EC number 231-793-3 and HS code 2833 29 20. It does not hold an E-code designation.
In water treatment, zinc sulfate acts as a coagulation aid and algaecide, releasing zinc ions that disrupt microbial cell membranes. In personal care formulations, it functions as a skin conditioner and humectant by binding moisture within the stratum corneum. Agriculture applications rely on its role as a zinc micronutrient source and foliar antimicrobial agent.
Zinc sulfate is available in grades conforming to Ph.Eur., FCC, and REACH registration requirements, supporting pharmaceutical, food-contact, and industrial end uses. Procurement teams should confirm grade specification against intended application, as purity thresholds differ between agricultural and pharmaceutical standards.
