Mica Iron Oxides ●
TL;DR. This ingredient functions as an insoluble mineral colorant and effect pigment, adding tint, opacity, shimmer, and visual coverage in makeup and personal care formulas.
What does Mica Iron Oxides do in a cosmetic formula?
This ingredient functions as an insoluble mineral colorant and effect pigment, adding tint, opacity, shimmer, and visual coverage in makeup and personal care formulas.
Is Mica Iron Oxides clean?
From a clean-beauty perspective, it is generally well tolerated on skin and not a common sensitizer. The main scrutiny is supply-chain traceability for mined materials and inhalation considerations in loose powders, rather than leave-on skin irritation.
Is Mica Iron Oxides sustainable?
This material is mineral-derived and mined, so sustainability depends on responsible extraction, worker protections, and traceable sourcing. It is inert and not biodegradable in the usual organic sense, but it does not behave like a persistent synthetic polymer in water systems.
Is Mica Iron Oxides COSMOS-approved?
It is generally permitted under COSMOS natural and organic products when it meets purity, colorant, and sourcing requirements. Its Green Chemistry profile is mixed, with low reactivity and no solvent-heavy function in formulas, but nonrenewable mineral sourcing and mining impacts keep it from being fully aligned.
How does Mica Iron Oxides work chemically?
This material combines plate-like aluminosilicate particles with inorganic colorant particles, creating opacity, shimmer, and shade control through light reflection and absorption. Typical use ranges from trace tinting to high-load color cosmetics, often about 1 to 60% depending on payoff, and it is insoluble, heat-stable, and stable across normal cosmetic pH.
