May Contain/Peut Contenir Iron Oxides ●
TL;DR. This ingredient is an inorganic colorant used to give cosmetics red, yellow, brown, and black tones. It also helps build opacity in complexion products, eye makeup, and tinted skin care.
What does May Contain/Peut Contenir Iron Oxides do in a cosmetic formula?
This ingredient is an inorganic colorant used to give cosmetics red, yellow, brown, and black tones. It also helps build opacity in complexion products, eye makeup, and tinted skin care.
Is May Contain/Peut Contenir Iron Oxides clean?
Clean-beauty frameworks generally accept it, with routine attention to trace heavy-metal specifications and particle-size claims. It is insoluble and nonreactive on skin, so sensitization potential is low.
Is May Contain/Peut Contenir Iron Oxides sustainable?
This material is mineral-derived or synthetically produced from abundant inorganic feedstocks. It is not biodegradable in the usual organic-chemistry sense, but it is persistent as an inert mineral particle rather than a bioaccumulative organic pollutant.
Is May Contain/Peut Contenir Iron Oxides COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s purity and colorant requirements. Its Green Chemistry profile is strongest on stability, low reactivity, and low skin reactivity, with a weaker fit on renewability because the feedstocks are mineral rather than plant-based.
How does May Contain/Peut Contenir Iron Oxides work chemically?
The molecule category is crystalline inorganic metal-oxygen pigment particles, with shade controlled by oxidation state, hydration, and particle morphology. It is insoluble, photostable, and broadly pH-stable in cosmetic systems, and use levels are color-dependent, from trace tinting amounts to double-digit percentages in high-pigment makeup.
