All Shades May Contain: CI 77891 ●
TL;DR. This ingredient is used primarily as a white colorant and opacifier, adding brightness, coverage, and shade adjustment in makeup and personal care formulas. In regulated sunscreen systems, the same material can also function by scattering UV light.
What does All Shades May Contain: CI 77891 do in a cosmetic formula?
This ingredient is used primarily as a white colorant and opacifier, adding brightness, coverage, and shade adjustment in makeup and personal care formulas. In regulated sunscreen systems, the same material can also function by scattering UV light.
Is All Shades May Contain: CI 77891 clean?
It is generally well tolerated on skin and is not a common sensitizer. Clean-standard friction usually centers on respirable loose powders, spray formats, and nano-size forms rather than normal dermal use.
Is All Shades May Contain: CI 77891 sustainable?
This material comes from mined mineral feedstocks that require refining, so its footprint is tied to extraction, energy use, and waste management. It is inorganic and does not biodegrade, but it is chemically stable and not considered bioaccumulative in typical pigment-grade use.
Is All Shades May Contain: CI 77891 COSMOS-approved?
It is permitted as a mineral colorant in COSMOS-natural and COSMOS-organic products, with nano forms subject to specific approval and labeling conditions. From a Green Chemistry view, it has low skin reactivity and high stability, but mining, energy-intensive processing, and no biodegradability keep it from a stronger alignment.
How does All Shades May Contain: CI 77891 work chemically?
The molecule is an insoluble inorganic metal oxide lattice used from trace shade-balancing amounts to double-digit percentages when strong opacity is needed. It is stable across normal cosmetic pH and heat conditions, disperses rather than dissolves, and often uses surface treatments to improve spread, reduce aggregation, and control photocatalytic behavior.
