TL;DR. This ingredient functions as a black inorganic colorant, adding depth, opacity, and shade adjustment in makeup, tinted skin care, hair color, and complexion products.
What does Ci 77499/Iron Oxides do in a cosmetic formula?
This ingredient functions as a black inorganic colorant, adding depth, opacity, and shade adjustment in makeup, tinted skin care, hair color, and complexion products.
Is Ci 77499/Iron Oxides clean?
It is generally well accepted in clean-beauty frameworks because it is inert, low-sensitizing, and not a common irritation trigger. The main quality concern is trace heavy-metal control, which is addressed through cosmetic-grade purity specifications.
Is Ci 77499/Iron Oxides sustainable?
This material is mineral-derived or made from mineral feedstocks, with no agricultural land-use pressure. It is not biodegradable in the organic-chemistry sense, but it is an inert mineral pigment and is not associated with bioaccumulation like persistent organic pollutants.
Is Ci 77499/Iron Oxides COSMOS-approved?
It is permitted in COSMOS natural and organic products as an approved mineral colorant when it meets purity and processing requirements. From a Green Chemistry lens, it scores well for inertness and low reactivity, though it is not renewable and depends on mineral extraction or mineral-based manufacturing.
How does Ci 77499/Iron Oxides work chemically?
The molecule is an insoluble inorganic pigment lattice with divalent and trivalent metal centers, which gives a strong black color and high opacity. It is stable across typical cosmetic pH ranges, used at highly variable levels depending on shade intensity, and requires good dispersion in oils, waxes, esters, or treated powder systems for even color payoff.
