CI 77510 ●
TL;DR. This ingredient is used as an inorganic blue pigment, adding color and opacity to makeup, nail products, and some personal care formulas. It is a colorant rather than a skin-care active.
What does CI 77510 do in a cosmetic formula?
This ingredient is used as an inorganic blue pigment, adding color and opacity to makeup, nail products, and some personal care formulas. It is a colorant rather than a skin-care active.
Is CI 77510 clean?
From a clean-beauty perspective, this ingredient has friction because it is a synthetic colorant and is subject to use-area restrictions in some regulations. It is generally low-migration and low-reactivity in finished products because it is highly insoluble.
Is CI 77510 sustainable?
This material is mineral-derived and synthetically processed, rather than renewable. It is not expected to biodegrade, but its insolubility limits mobility in water compared with soluble colorants.
Is CI 77510 COSMOS-approved?
This ingredient is not aligned with COSMOS-natural or COSMOS-organic standards because synthetic colorants of this type are generally not permitted. From a Green Chemistry view, it scores modestly because it is stable and used at low levels, but it is non-renewable and not biodegradable.
How does CI 77510 work chemically?
The molecule is an insoluble iron coordination pigment, with iron centers bridged by tightly bound cyanide ligands in a crystal lattice. It is used at low pigment levels depending on shade, is stable across typical anhydrous and emulsion systems, and should be dispersed well to prevent speckling or uneven color payoff.
