Cobalt(ii) chloride

Cobalt(II) Chloride, CAS 7646-79-9, is an inorganic cobalt salt also referred to as CoCl2, cobalt muriate, or dichlorocobalt. It carries no assigned E-code and is classified under HS code 28273930. It is commercially available in anhydrous and hydrated forms, each with distinct physical characteristics.

In textile and leather processing, Cobalt(II) Chloride acts as a catalyst and mordant, facilitating dye fixation onto fibres through coordination bonding. In agriculture and animal feed, it supplies trace cobalt required for vitamin B12 synthesis in ruminants. Personal care formulators incorporate it as a skin conditioning agent at controlled concentrations.

Cobalt(II) Chloride is supplied in technical and reagent grades, with sourcing subject to REACH regulation (EC 1907/2006) due to its classification as a substance of very high concern. Procurement teams should confirm SDS documentation and supplier authorisation status prior to ordering. Packaging typically ranges from laboratory quantities to bulk industrial formats.
