Description
Nickel Sulfate Hexahydrate (CAS 10101-97-0, EC 600-152-3, HS 28332400), also known as nickelous sulfate hexahydrate or hexaaquanickel(II) sulfate, is an inorganic nickel salt produced by dissolving nickel in sulfuric acid. It carries no E-code designation and is distinct from anhydrous nickel sulfate in both solubility profile and industrial handling.
In electroplating and surface finishing, it serves as the primary nickel ion source in electrolytic baths, depositing uniform nickel coatings onto metal substrates through controlled current application. In personal care formulations, it functions as a skin conditioner and humectant by attracting and retaining moisture within the product matrix. It also acts as a catalyst precursor in hydrogenation processes across chemical manufacturing.
Nickel Sulfate Hexahydrate is available in technical and analytical standard grades, with REACH registration required for EU supply chains. Packaging typically ranges from laboratory quantities to bulk industrial formats. Procurement should confirm SDS compliance under EU GHS/CLP, as the substance carries sensitisation and carcinogenicity classifications under current European regulation.
