This ingredient is a red to reddish-brown colorant used to tint makeup, skincare, hair products, and soaps. It also adds opacity and can help adjust shade depth in complexion formulas.
Is 77491 clean?
Clean-beauty frameworks generally accept it as a low-sensitization colorant, with attention to trace metals controlled by cosmetic colorant specifications. Sensitivity is uncommon because it is insoluble and relatively non-reactive on skin.
Is 77491 sustainable?
It comes from mineral sources or controlled mineral-salt manufacturing, so the footprint depends on mining, purification, and energy use. It does not biodegrade because it is inorganic, but it is generally inert and not expected to bioaccumulate like many persistent organic pollutants.
Is 77491 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets purity and colorant requirements, though it does not count toward organic content. From a Green Chemistry view, it is stable and low-reactivity, but it is not renewable and requires mineral processing.
How does 77491 work chemically?
This material is an insoluble inorganic crystalline pigment, and performance depends on particle size, surface treatment, and dispersion quality. It is highly stable to light, heat, and typical cosmetic pH ranges, and use levels vary widely from trace shade adjustment to several percent in color cosmetics.
