About

An iron-based complex with dinitroso and mercaptopropionate groups — a highly specialized and reactive compound. The dinitroso component is particularly concerning from a safety standpoint.

Bis-(Dinitroso Ferrate Mercaptopropionate) is a coordination complex of iron with nitroso ligands and mercaptopropionate (3-mercaptopropionic acid) groups. The presence of dinitroso iron complexes is unusual in cosmetics and more commonly associated with industrial applications. N-nitroso compounds are among the most well-studied classes of carcinogens, and while this specific compound's nitroso groups are metal-coordinated (potentially less reactive), the structural alert is serious. Mercaptopropionate adds a thiol character that can reduce oxidative stress but also introduces its own reactivity profile. Not a standard cosmetic ingredient.

Known concerns

  • Nitroso structural alerts — potential carcinogen concern
  • Metal coordination changes but does not eliminate nitroso risk
  • Thiol reactivity — potential skin sensitization
  • Not a standard or well-studied cosmetic ingredient
