Ferric Ammonium Ferrocyanide

Description

Ferric Ammonium Ferrocyanide, also known as Prussian Blue, is a synthetic pigment widely used in cosmetics and personal care products. This inorganic compound is characterized by its deep blue color and chemical stability. In skincare formulations, it primarily functions as a colorant, imparting a distinctive hue to various products such as eyeshadows, eyeliners, and other color cosmetics.

The ingredient's molecular structure consists of iron ions coordinated with cyanide groups, forming a complex lattice. This unique composition contributes to its excellent light-fastness and resistance to environmental factors. Ferric Ammonium Ferrocyanide is generally considered safe for topical use in cosmetic concentrations, as it has low skin penetration due to its large molecular size.

In addition to its coloring properties, Ferric Ammonium Ferrocyanide exhibits some antioxidant capabilities, potentially offering minor protective benefits against free radical damage. However, its primary role remains aesthetic. The pigment is insoluble in water and most organic solvents, ensuring long-lasting color payoff in formulations. When used in skincare products, it is typically combined with other ingredients to achieve desired shades and textures.
