What does MICAC I 77891 do in a cosmetic formula?
This ingredient functions as a mineral colorant, opacifier, and pearlescent effect pigment. It adds whiteness, coverage, brightness, and shimmer in makeup, sunscreen, and complexion products.
Is MICAC I 77891 clean?
It is generally accepted in clean beauty frameworks for topical use, with low skin-irritation potential. Scrutiny is higher for respirable loose powders, sprays, nano-sized grades, and trace heavy-metal purity controls.
Is MICAC I 77891 sustainable?
This material is mineral-derived and nonrenewable, so sourcing traceability and mining practices matter. It is inert and does not biodegrade in the organic sense, but it is not a persistent synthetic polymer.
Is MICAC I 77891 COSMOS-approved?
It is generally permitted in COSMOS-natural and COSMOS-organic products as an allowed mineral colorant when purity and particle-size requirements are met. Its Green Chemistry profile is mixed, with good chemical stability and low reactivity, but reliance on mining and energy-intensive processing.
How does MICAC I 77891 work chemically?
The material is based on layered mineral platelets paired with high-refractive-index inorganic white particles, which create opacity, brightness, and pearl effects through light scattering. Use levels can range from below 1% for subtle radiance to 10% or more in color cosmetics, and it is insoluble and stable across normal cosmetic pH ranges.
