May contain Iron Oxides (CI 77492 ●
TL;DR. This ingredient is an inorganic pigment used to give formulas a yellow tone and adjust shade depth in makeup, tinted skin care, and powders. It is insoluble, so it provides color by dispersion rather than by dissolving into the formula.
What does May contain Iron Oxides (CI 77492 do in a cosmetic formula?
This ingredient is an inorganic pigment used to give formulas a yellow tone and adjust shade depth in makeup, tinted skin care, and powders. It is insoluble, so it provides color by dispersion rather than by dissolving into the formula.
Is May contain Iron Oxides (CI 77492 clean?
From a clean beauty perspective, this ingredient is generally well tolerated because it is inert and not a common sensitizer. The main quality issue is trace heavy-metal impurities, which are controlled by cosmetic colorant purity specifications.
Is May contain Iron Oxides (CI 77492 sustainable?
This material is mineral-derived or nature-identical and does not rely on agricultural feedstocks. It is not biodegradable in the usual organic sense, but it is inorganic, stable, and not expected to bioaccumulate in the way many persistent organic compounds can.
Is May contain Iron Oxides (CI 77492 COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic frameworks when it meets the standard’s colorant and purity requirements. Its Green Chemistry profile is strongest on stability, low reactivity, and low irritation, while its weaknesses are non-renewable mineral sourcing and lack of biodegradability.
How does May contain Iron Oxides (CI 77492 work chemically?
The molecule is an insoluble inorganic pigment with a hydrated metal-oxygen lattice that gives a yellow hue and remains stable across typical cosmetic pH ranges. Use levels vary widely by product type, from trace shade correction to several percent in complexion products, and it must be well dispersed to prevent speckling or uneven payoff.
