CI 77492). May Contain/Peut Contenir: Iron Oxides

TL;DR. This ingredient is a mineral colorant used to create yellow, beige, tan, and ochre tones in makeup, tinted skincare, soaps, and personal care products. It also contributes opacity and shade correction in complexion formulas.

What does CI 77492). May Contain/Peut Contenir: Iron Oxides do in a cosmetic formula?

This ingredient is a mineral colorant used to create yellow, beige, tan, and ochre tones in makeup, tinted skincare, soaps, and personal care products. It also contributes opacity and shade correction in complexion formulas.

Is CI 77492). May Contain/Peut Contenir: Iron Oxides clean?

From a clean beauty perspective, it is generally well tolerated because it is insoluble, inert on skin, and not a common allergen. Clean-standard scrutiny usually focuses on heavy-metal impurity limits and cosmetic-grade purity rather than the material itself.

Is CI 77492). May Contain/Peut Contenir: Iron Oxides sustainable?

This material is mineral-based and may be mined or synthetically produced, with synthetic grades often offering better purity and shade consistency. It is not biodegradable because it is inorganic, but it is environmentally persistent in a relatively inert mineral form.

Is CI 77492). May Contain/Peut Contenir: Iron Oxides COSMOS-approved?

It is permitted under COSMOS-natural and COSMOS-organic standards when it meets cosmetic colorant and impurity requirements. Its Green Chemistry fit is strongest on low skin reactivity and stability, while weaker points are non-renewable mineral sourcing and lack of biodegradability.

How does CI 77492). May Contain/Peut Contenir: Iron Oxides work chemically?

The molecule is an insoluble inorganic crystalline pigment, so it does not dissolve into water or oil and must be well dispersed for even color payoff. Typical use depends on shade target, often below 1% in lightly tinted products and several percent in color cosmetics, with good light and pH stability but possible shade change under high heat.
