Nickel oxide

Nickel Oxide (CAS 1313-99-1, EC 215-215-7, formula NiO) is an inorganic compound also known as Nickel Monoxide or Nickelous Oxide. It carries no assigned E-code and is classified under HS code 28254000. It is commercially available as a technical-grade powder used across industrial formulation sectors.

In coatings and pigment systems, Nickel Oxide functions as an inorganic colorant, imparting stable black or brown tones with strong heat resistance. In personal care formulations, it has been documented as a skin-conditioning and protective agent, where its surface chemistry supports controlled interaction with biological substrates. It also exhibits antimicrobial activity relevant to preservation applications.

Nickel Oxide is supplied as a technical-grade powder and is subject to REACH registration requirements within the EU, with suppliers required to provide a compliant Safety Data Sheet. Procurement teams should verify SVHC status and occupational exposure limits prior to sourcing. Packaging formats typically include multi-layer bags or drums depending on order volume.
