Iron Oxides ] <ILN51390> ●
TL;DR. This ingredient is primarily a colorant and opacifier, used to create red, yellow, brown, and black tones in makeup, sunscreen, and complexion products. It also helps improve coverage and visual uniformity.
What does Iron Oxides ] <ILN51390> do in a cosmetic formula?
This ingredient is primarily a colorant and opacifier, used to create red, yellow, brown, and black tones in makeup, sunscreen, and complexion products. It also helps improve coverage and visual uniformity.
Is Iron Oxides ] <ILN51390> clean?
It has broad clean-standard acceptance because it is inert, non-sensitizing for most users, and not a common allergen. The main quality focus is tight control of trace-metal impurities and particle-size specifications in cosmetic grades.
Is Iron Oxides ] <ILN51390> sustainable?
This material is inorganic and mineral-derived or synthetically produced to match mineral chemistry, with no biodegradation pathway because it is not organic matter. It is persistent in the simple mineral sense, but it is chemically stable, non-volatile, and used at low environmental mobility in finished products.
Is Iron Oxides ] <ILN51390> COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards as an allowed inorganic colorant when it meets cosmetic purity requirements. From a Green Chemistry view, it scores well for stability and low reactivity, while its mineral origin and non-biodegradable nature make the sustainability profile more about responsible sourcing and impurity control than renewable feedstock.
How does Iron Oxides ] <ILN51390> work chemically?
This ingredient is a family of insoluble crystalline particles made from a transition metal bound to oxygen, with shade determined by crystal phase, hydration state, and particle size. It is typically used from trace tinting levels to well over 10% in high-coverage color cosmetics, and it is stable to light, heat, and normal cosmetic pH ranges.
