What does Iron Oxides Ci 77499 do in a cosmetic formula?
This ingredient is a black inorganic pigment used to add color, opacity, and shade depth in makeup, tinted skin care, hair color, and some personal care products.
Is Iron Oxides Ci 77499 clean?
It is broadly accepted in clean-beauty frameworks because it is inert, non-sensitizing for most users, and tightly regulated as a color additive. The main quality consideration is compliance with limits for elemental impurities.
Is Iron Oxides Ci 77499 sustainable?
This material is mineral-based or synthetically produced from abundant mineral feedstocks, so it is not renewable in the agricultural sense. It is inorganic and not biodegradable, but it is insoluble, stable, and generally low-mobility in the environment.
Is Iron Oxides Ci 77499 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets approved colorant and purity requirements, although it does not contribute to organic content. From a Green Chemistry view, it scores well for stability and low reactivity, with the main limitation being non-renewable mineral sourcing.
How does Iron Oxides Ci 77499 work chemically?
The molecule is an insoluble, mixed-valence inorganic oxide pigment that gives a dense black tone through strong visible-light absorption. Typical use ranges from trace tinting levels below 1% to several percent in color cosmetics, and it is highly stable to light, heat, and normal cosmetic pH conditions but needs good dispersion to prevent speckling or shade drift.
