Description
Zinc Acetate Dihydrate (CAS 5970-45-6) is an inorganic zinc salt supplied as a crystalline solid, also known commercially as Wilzin and referenced as Zinc Diacetate Dihydrate. It carries no assigned E-code and is identified under EC 611-865-4. It is distinct from the anhydrous form and the monohydrate variant.
In pharmaceutical manufacturing, it serves as an active ingredient in Wilson's disease treatment, where it blocks intestinal copper absorption by inducing metallothionein synthesis. In polymer production, it functions as a catalyst for polymerisation and transesterification reactions. It also acts as a buffering agent and antimicrobial additive in topical cosmetic formulations.
Zinc Acetate Dihydrate is available in Ph.Eur. and FCC grades to meet pharmaceutical and food-contact requirements respectively. It falls under REACH registration obligations within the EU and is classified under HS code 29152900. Standard packaging includes fibre drums and multi-layer bags, with bulk quantities available on request.
