CI77288/Chromium Oxide Greens ●
TL;DR. This ingredient is an inorganic green pigment used to give color and opacity to makeup, nail products, soaps, and other personal care formulas. It is a colorant rather than a treatment active.
What does CI77288/Chromium Oxide Greens do in a cosmetic formula?
This ingredient is an inorganic green pigment used to give color and opacity to makeup, nail products, soaps, and other personal care formulas. It is a colorant rather than a treatment active.
Is CI77288/Chromium Oxide Greens clean?
From a clean-beauty perspective, this ingredient is generally accepted when it meets cosmetic-grade purity limits for soluble metals and trace contaminants. Its insoluble form has low skin penetration and low irritation potential, but the metal-impurity profile matters.
Is CI77288/Chromium Oxide Greens sustainable?
This material is mineral-derived and typically made through mined feedstocks and high-temperature processing. It is not biodegradable because it is inorganic, and its main sustainability tradeoffs are mining impacts, refining, and furnace energy use.
Is CI77288/Chromium Oxide Greens COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic as an approved mineral colorant when cosmetic purity requirements are met. Its Green Chemistry fit is mixed, since it is stable and low-reactivity in use, but nonrenewable and energy-intensive to produce.
How does CI77288/Chromium Oxide Greens work chemically?
The molecule is a crystalline trivalent metal oxide with a corundum-type lattice, giving it strong lightfastness, heat stability, and very low solubility in water and oils. It is typically dispersed rather than dissolved, so performance depends on particle size, surface treatment, milling quality, and compatibility with the formula base.
