Iron Oxides \ Cl 77492\ ●
TL;DR. This ingredient is an inorganic mineral pigment used to give cosmetics a yellow to ochre color. It is common in foundations, concealers, tinted moisturizers, eye products, and complexion powders where opacity and shade control matter.
What does Iron Oxides \ Cl 77492\ do in a cosmetic formula?
This ingredient is an inorganic mineral pigment used to give cosmetics a yellow to ochre color. It is common in foundations, concealers, tinted moisturizers, eye products, and complexion powders where opacity and shade control matter.
Is Iron Oxides \ Cl 77492\ clean?
This ingredient is generally well tolerated because it is insoluble, inert on skin, and not a common sensitizer. Clean-beauty concerns usually center on trace heavy-metal impurities, which are managed through cosmetic-grade specifications and regulatory limits.
Is Iron Oxides \ Cl 77492\ sustainable?
This material is mineral-derived or synthetically produced from abundant inorganic feedstocks. It is not biodegradable in the usual organic-molecule sense, but it is environmentally stable, non-bioaccumulative, and used at low to moderate levels in finished products.
Is Iron Oxides \ Cl 77492\ COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets purity and sourcing requirements for mineral pigments. From a Green Chemistry view, it scores well for stability, low reactivity, and low skin irritation, with weaker alignment on renewability because it is inorganic rather than bio-based.
How does Iron Oxides \ Cl 77492\ work chemically?
This inorganic mineral pigment is an insoluble metal-oxide/hydroxide solid whose color comes from its crystal structure rather than dye-like solubility. Typical use ranges run from trace tinting levels below 1% to several percent in complexion products, and its shade is generally pH-stable, although very high processing temperatures can dehydrate the crystal form and shift the color redder.
