CI 77510
Is CI 77510 safe for seborrheic dermatitis?
CI 77510 needs consideration within its exact material identity and finished product. The checked EU entry for Ferric Ammonium Ferrocyanide includes a purity condition requiring the specified material to be free of cyanide ions; this is not a ban on every use.
The catalog includes related ferrocyanide names, which should not be treated as identical preparations without checking their identity. A colourant permission or purity condition does not establish personal tolerance, a treatment effect or a Malassezia response. Consider the complete product and intended exposure, and seek advice if irritation persists.

What is CI 77510 used for in skincare?
CI 77510 is an inorganic blue colourant with recorded ferrocyanide and Pigment Blue 27 names. The checked regulatory entry specifies Ferric Ammonium Ferrocyanide and its CAS identity. Matching that form matters when a purity condition is applied to a source or formulation.
