TL;DR. This ingredient is an inorganic colorant and pearlescent pigment used to add white opacity, shimmer, brightness, and slip in makeup and some personal care formulas.
What does CI 77163 do in a cosmetic formula?
This ingredient is an inorganic colorant and pearlescent pigment used to add white opacity, shimmer, brightness, and slip in makeup and some personal care formulas.
Is CI 77163 clean?
From a clean-beauty perspective, it is generally accepted, but it can feel itchy or irritating for some sensitive users, especially in loose mineral powders. Responsible sourcing and contaminant testing matter because mineral pigments can carry trace metal impurities if poorly controlled.
Is CI 77163 sustainable?
This material is mineral-derived and made through mining and inorganic processing, so it is not renewable. It is not biodegradable in the usual organic-chemistry sense, but it is generally inert and not known for bioaccumulation in cosmetic use.
Is CI 77163 COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic as an approved mineral colorant when it meets purity requirements. Its Green Chemistry profile is mixed, with good stability and low reactivity, but nonrenewable sourcing and mineral processing keep it from being a fully aligned material.
How does CI 77163 work chemically?
The molecule is an inorganic layered crystalline material that forms plate-like particles, giving optical reflectance, opacity, and a pearly finish. Use levels vary widely by product type, from low single digits in creams to much higher levels in pressed or loose powders, and it is broadly stable across typical cosmetic pH ranges.
