Ferric Ammonium Ferrocyanide CI 77510 ●
TL;DR. This ingredient is an inorganic blue colorant used to give cosmetics, eye products, soaps, and personal care formulas a stable blue tone. It is a pigment rather than a dye, so it stays dispersed in the formula instead of dissolving.
What does Ferric Ammonium Ferrocyanide CI 77510 do in a cosmetic formula?
This ingredient is an inorganic blue colorant used to give cosmetics, eye products, soaps, and personal care formulas a stable blue tone. It is a pigment rather than a dye, so it stays dispersed in the formula instead of dissolving.
Is Ferric Ammonium Ferrocyanide CI 77510 clean?
From a clean-beauty perspective, it is generally treated as an approved color additive with low skin absorption because the complex is highly insoluble. It still has some clean-standard friction because it is a synthetic inorganic pigment and color additives may be restricted by product type or region.
Is Ferric Ammonium Ferrocyanide CI 77510 sustainable?
This material is mineral and industrially synthesized rather than plant-derived, and it is not biodegradable in the usual organic-material sense. Its insolubility limits mobility in water, but inorganic pigments can persist in sediments or solid waste streams.
Is Ferric Ammonium Ferrocyanide CI 77510 COSMOS-approved?
It has limited COSMOS alignment because it is a synthetic inorganic colorant, and acceptance depends on the standard’s permitted colorant list and the product category. From a Green Chemistry lens, it scores better for low use levels and stability than for renewable sourcing or biodegradability.
How does Ferric Ammonium Ferrocyanide CI 77510 work chemically?
The molecule is an insoluble iron coordination complex with tightly bound cyanide ligands in a lattice structure, which is why it behaves as a particulate pigment rather than a soluble salt. It is typically used at low color-adjusting levels, is stable in many anhydrous and neutral systems, and can be sensitive to strongly alkaline conditions that may shift shade or reduce color strength.
