CI 77492/77499 ●
TL;DR. This ingredient functions as an insoluble colorant, giving cosmetics yellow, brown, gray, or black tones and helping adjust shade opacity in makeup, hair color, and tinted skin products.
What does CI 77492/77499 do in a cosmetic formula?
This ingredient functions as an insoluble colorant, giving cosmetics yellow, brown, gray, or black tones and helping adjust shade opacity in makeup, hair color, and tinted skin products.
Is CI 77492/77499 clean?
It is generally well tolerated because the particles are insoluble and not known as common sensitizers in normal cosmetic use. The main clean-standard focus is colorant-grade purity, especially trace metal limits and particle-size control.
Is CI 77492/77499 sustainable?
This material is mineral-derived or manufactured from abundant inorganic feedstocks, so it is not renewable but has a relatively simple supply chain. It does not biodegrade because it is inorganic, but it is generally considered environmentally inert and non-bioaccumulative.
Is CI 77492/77499 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets approved colorant specifications and purity criteria. From a Green Chemistry view, it scores well on stability, low reactivity, and low use levels, with weaker alignment on renewability and biodegradability.
How does CI 77492/77499 work chemically?
This compound is an insoluble inorganic pigment system whose color comes from metal-oxygen crystal structures and particle-size-dependent light absorption. It is typically used from trace tinting levels up to several percent in color cosmetics, remains stable across normal cosmetic pH ranges, and needs good dispersion in oils, powders, or emulsions to prevent specking.
