CI 77400 ●
TL;DR. This ingredient is a metallic colorant used to create warm gold-brown shimmer, opacity, and reflective effects in makeup and decorative personal care products.
What does CI 77400 do in a cosmetic formula?
This ingredient is a metallic colorant used to create warm gold-brown shimmer, opacity, and reflective effects in makeup and decorative personal care products.
Is CI 77400 clean?
From a clean-beauty perspective, it is a regulated color additive rather than a treatment ingredient, so the main issue is purity control for trace metals and use-area restrictions. It is generally low-irritation on intact skin when properly specified, but it has more standards friction than simple mineral pigments.
Is CI 77400 sustainable?
This material comes from mined, nonrenewable metals and requires alloying and particle-size processing. It does not biodegrade, although inorganic pigments are typically used at low levels and are not associated with the same persistence profile as many synthetic organic polymers.
Is CI 77400 COSMOS-approved?
It may be accepted in COSMOS-natural color cosmetics when it meets permitted colorant and purity requirements, but it is not a strong fit for COSMOS-organic positioning because it is non-agricultural and nonrenewable. Green Chemistry alignment is mixed, with good formulation efficiency but limited renewability and no biodegradability.
How does CI 77400 work chemically?
The molecule is better understood as a finely milled metallic alloy particle that provides color by light reflection rather than dye-like solubility. It is insoluble in water and oils, is typically dispersed rather than dissolved, and performs best in anhydrous or low-water systems where oxidation and surface dulling are better controlled.
