Cl 77499/IRON OXIDES ●
TL;DR. This ingredient is an inorganic colorant used to create black, gray, and depth-adjusting shades in makeup, skin care, hair color, and tinted SPF formulas. It also adds opacity and helps tune undertones in pigment blends.
What does Cl 77499/IRON OXIDES do in a cosmetic formula?
This ingredient is an inorganic colorant used to create black, gray, and depth-adjusting shades in makeup, skin care, hair color, and tinted SPF formulas. It also adds opacity and helps tune undertones in pigment blends.
Is Cl 77499/IRON OXIDES clean?
From a clean-beauty perspective, this ingredient is generally well accepted when cosmetic-grade purity specifications are met. The main quality consideration is control of trace metal impurities, not routine skin irritation or sensitization.
Is Cl 77499/IRON OXIDES sustainable?
This material is mineral-derived or synthetically produced from abundant inorganic feedstocks. It is not biodegradable in the way organic ingredients are, but it is inert, non-bioaccumulative, and used at relatively low levels in finished products.
Is Cl 77499/IRON OXIDES COSMOS-approved?
It is permitted in COSMOS-natural and COSMOS-organic products as an approved mineral colorant, provided applicable purity requirements are met. Its Green Chemistry fit is strongest on stability and low reactivity, with the main caveat being the energy and extraction footprint of mineral processing.
How does Cl 77499/IRON OXIDES work chemically?
This compound is a crystalline inorganic pigment with metal cations and oxygen arranged in a lattice that absorbs broadly across visible light, giving strong black coloration and high tinting strength. It is stable across normal cosmetic pH ranges, compatible with anhydrous and emulsion systems, and typically used from trace shade-adjusting amounts up to several percent in color cosmetics.
