What does Iron Oxides Ci 77492 do in a cosmetic formula?
This ingredient is an inorganic colorant used to create yellow, beige, and warm undertones in makeup, sunscreens, complexion products, and tinted skin care. It provides opacity and shade control rather than preservation, cleansing, or skin treatment.
Is Iron Oxides Ci 77492 clean?
This ingredient is generally well accepted in clean beauty because it is non-fragrant, low in sensitization potential, and widely used in products for sensitive skin. The main quality issue is trace heavy-metal control, which reputable suppliers manage through cosmetic-grade purity specifications.
Is Iron Oxides Ci 77492 sustainable?
This material is mineral-derived or nature-identical through controlled manufacturing, so its sustainability profile depends on mining practices, energy use, and purification standards. It is inorganic and does not biodegrade, but it is stable, inert, and not considered a bioaccumulative organic pollutant.
Is Iron Oxides Ci 77492 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets the standard’s purity and colorant requirements. From a Green Chemistry perspective, it scores well for stability, low reactivity, and low irritation, with weaker points around nonrenewable mineral sourcing and limited end-of-life transformation.
How does Iron Oxides Ci 77492 work chemically?
The molecule is an insoluble inorganic pigment built from a crystalline metal-oxygen-hydroxide lattice, which is why it is light-stable, water-insoluble, and not pH-sensitive under normal cosmetic conditions. Use levels vary widely by product type, from trace tinting amounts below 1% to much higher levels in foundations, concealers, and pressed powders, and formulators usually disperse it with wetting agents or surface treatments for even color payoff.
