Ferric Ferrocyanide/Ferric Ammonium Ferrocyanide ●
TL;DR. It functions as an insoluble blue inorganic pigment, mainly used to color eye makeup, face makeup, nail products, and some rinse-off or leave-on formulas. It provides strong blue tone and opacity rather than treatment benefit.
What does Ferric Ferrocyanide/Ferric Ammonium Ferrocyanide do in a cosmetic formula?
It functions as an insoluble blue inorganic pigment, mainly used to color eye makeup, face makeup, nail products, and some rinse-off or leave-on formulas. It provides strong blue tone and opacity rather than treatment benefit.
Is Ferric Ferrocyanide/Ferric Ammonium Ferrocyanide clean?
From a clean-beauty perspective, it is a regulated color additive with low skin absorption because it remains largely insoluble in finished products. The main considerations are cosmetic-grade purity, trace-metal specifications, and some brand-level friction around synthetic pigments.
Is Ferric Ferrocyanide/Ferric Ammonium Ferrocyanide sustainable?
It is synthetically produced from mineral and industrial feedstocks rather than renewable agricultural sources. As an inorganic pigment, it does not biodegrade in the usual way and can persist as a stable particulate, although its low solubility limits mobility and bioavailability.
Is Ferric Ferrocyanide/Ferric Ammonium Ferrocyanide COSMOS-approved?
It can be accepted in COSMOS-natural style formulations when it meets the relevant colorant and purity requirements, but it is not an organic ingredient and does not contribute to organic content. Its Green Chemistry fit is partial, with low-use efficiency and high stability on the positive side, but nonrenewable sourcing and lack of biodegradability on the limiting side.
How does Ferric Ferrocyanide/Ferric Ammonium Ferrocyanide work chemically?
The molecule is an iron-based coordination-complex pigment with iron centers linked through tightly bound carbon-nitrogen ligands, forming an intensely colored, insoluble lattice. It is typically used at low color-adjusting levels or higher pigment-load levels in color cosmetics, and it is generally stable across normal cosmetic pH ranges but should be formulated with attention to regulatory use areas and purity specifications.
