TL;DR. This ingredient is a black mineral pigment used to give color, deepen shades, and improve opacity in makeup, skin care, hair color, and personal care products.
What does CI 77499/Iron Oxides. F.I.L. D166492/2 do in a cosmetic formula?
This ingredient is a black mineral pigment used to give color, deepen shades, and improve opacity in makeup, skin care, hair color, and personal care products.
Is CI 77499/Iron Oxides. F.I.L. D166492/2 clean?
It is widely accepted in clean-beauty frameworks because it is inert, non-sensitizing for most users, and not associated with common fragrance or preservative concerns. The main quality issue is purity, since colorants of this type must meet limits for trace metals and other impurities.
Is CI 77499/Iron Oxides. F.I.L. D166492/2 sustainable?
This material is typically mineral-derived or synthetically produced, and it is not biodegradable because it is inorganic. Its environmental profile is generally stable and low-reactivity, with the main considerations being mining impacts, energy use, and responsible impurity control.
Is CI 77499/Iron Oxides. F.I.L. D166492/2 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets approved colorant and purity requirements. From a Green Chemistry view, it is not renewable or biodegradable, but it is stable, low-reactivity, and can be produced without complex solvent chemistry.
How does CI 77499/Iron Oxides. F.I.L. D166492/2 work chemically?
The molecule is an inorganic, crystalline metal-oxygen pigment whose black color comes from broad visible-light absorption in a mixed-valence lattice. It is generally stable across cosmetic pH ranges and heat processing, and use levels vary from trace shade adjustment to much higher percentages in color cosmetics depending on opacity and tone.
