Ci 77289 ●
TL;DR. This ingredient is a mineral colorant used to give products a muted green shade, especially in makeup, soaps, and tinted personal care formulas. It functions as an insoluble pigment rather than a dye, so it disperses through the formula instead of dissolving.
What does Ci 77289 do in a cosmetic formula?
This ingredient is a mineral colorant used to give products a muted green shade, especially in makeup, soaps, and tinted personal care formulas. It functions as an insoluble pigment rather than a dye, so it disperses through the formula instead of dissolving.
Is Ci 77289 clean?
From a clean beauty perspective, this ingredient is generally accepted when it meets cosmetic-grade purity limits for trace metals. It has some framework friction because U.S. color-additive rules typically do not permit it in lip products, even though it is common in eye and face cosmetics.
Is Ci 77289 sustainable?
This material is mineral-derived and inorganic, so it is not biodegradable in the way plant or organic materials are. Its main sustainability considerations are mining, mineral processing, and responsible control of trace-metal impurities rather than aquatic breakdown.
Is Ci 77289 COSMOS-approved?
This ingredient is generally compatible with COSMOS-natural and COSMOS-organic products as a permitted mineral colorant when it meets purity and use-condition requirements. Its Green Chemistry profile is mixed, since it is stable, low-reactivity, and used at low levels, but it is nonrenewable and not biodegradable.
How does Ci 77289 work chemically?
This compound is not a discrete organic molecule, it is an insoluble hydrated inorganic pigment with color produced by trivalent metal centers in an oxide/hydroxide crystal lattice. Use level is shade-dependent, often below 1% for light tinting and several percent in color cosmetics, and it is stable across normal cosmetic pH, insoluble in water and oils, and not prone to oxidation in typical storage.
