Ci77491 ●
TL;DR. This ingredient is an inorganic colorant used to give cosmetics a red, rust, or warm brown tone. It is common in complexion makeup, lip color, eye products, and tinted skin care because it is opaque, light-stable, and easy to shade-blend.
What does Ci77491 do in a cosmetic formula?
This ingredient is an inorganic colorant used to give cosmetics a red, rust, or warm brown tone. It is common in complexion makeup, lip color, eye products, and tinted skin care because it is opaque, light-stable, and easy to shade-blend.
Is Ci77491 clean?
From a clean-beauty perspective, this ingredient is generally considered low-irritation and well accepted when it meets cosmetic purity specifications. The main scrutiny is trace heavy-metal impurities, which are controlled through colorant regulations and supplier testing.
Is Ci77491 sustainable?
This material is mineral-based or synthetically produced from abundant inorganic feedstocks, so it does not rely on crop agriculture or palm-derived inputs. It is not biodegradable in the usual organic-chemistry sense, but it is inert, non-volatile, and not associated with microplastic-style persistence concerns.
Is Ci77491 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when it meets the allowed colorant and purity requirements. Its Green Chemistry profile is strongest on stability, low reactivity, and low use levels, though it is not renewable and is an inorganic mineral material rather than a biodegradable organic compound.
How does Ci77491 work chemically?
This compound is an insoluble inorganic metal-oxygen lattice pigment with high opacity and strong resistance to light, heat, and oxidation. Use level is shade-dependent, often below 1% in lightly tinted products and much higher in color cosmetics, and it needs good dispersion in oils, waxes, silicones, or powder bases for even payoff.
