CI 77492[3][5] ●
TL;DR. This ingredient is an inorganic colorant used to give formulas a yellow to ochre tone. It is common in complexion makeup, mineral sunscreen tints, and color cosmetics because it is opaque, stable, and insoluble.
What does CI 77492[3][5] do in a cosmetic formula?
This ingredient is an inorganic colorant used to give formulas a yellow to ochre tone. It is common in complexion makeup, mineral sunscreen tints, and color cosmetics because it is opaque, stable, and insoluble.
Is CI 77492[3][5] clean?
From a clean-beauty perspective, this ingredient is generally well tolerated because it is inert, non-volatile, and not a common sensitizer. The main quality issue is pigment purity, so reputable suppliers control trace metals and particle-size specifications.
Is CI 77492[3][5] sustainable?
This material is mineral-derived or manufactured from abundant mineral feedstocks, with no palm or petrochemical supply-chain dependency. It does not biodegrade because it is inorganic, but it is considered environmentally stable and not bioaccumulative in the way many persistent organic compounds can be.
Is CI 77492[3][5] COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets approved colorant and impurity requirements. Its Green Chemistry fit is strongest on stability, low reactivity, and low use levels, and weaker on renewability because it is mineral rather than plant-derived.
How does CI 77492[3][5] work chemically?
The molecule is an inorganic, hydrated metal-oxide lattice rather than an organic dye, so it is insoluble in water and oils and functions by particle dispersion. It is typically used below 10% in complexion and color products, is stable across normal cosmetic pH ranges, and needs good milling or dispersion support for even shade payoff.
