Question 1

What does CI 77891 . Contains nuts: Brazil Nut do in a cosmetic formula?

Accepted Answer

This ingredient is a white mineral pigment, opacifier, and UV-scattering filter used to add coverage, brightness, and sun protection performance in makeup, skin care, and sunscreen formulas.

Question 2

Is CI 77891 . Contains nuts: Brazil Nut clean?

Accepted Answer

Clean-beauty standards generally accept it in non-inhalable products, but often apply extra scrutiny to nano grades and loose powders because particle size and exposure route matter. The nut note is not intrinsic to this mineral colorant and would point to a separate formulation or supply-chain disclosure.

Question 3

Is CI 77891 . Contains nuts: Brazil Nut sustainable?

Accepted Answer

This material is mineral-derived, so it comes from mining rather than renewable agriculture. It is not biodegradable, but it is largely inert in finished formulas, with environmental questions focused on mining impacts, particle size, coatings, and release into waterways.

Question 4

Is CI 77891 . Contains nuts: Brazil Nut COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic as a mineral colorant or UV-filter material when purity, coating, particle-size, and nano-disclosure requirements are met. From a Green Chemistry view, it scores well for stability and low reactivity, but less well for non-renewable sourcing and lack of biodegradability.

Question 5

How does CI 77891 . Contains nuts: Brazil Nut work chemically?

Accepted Answer

The molecule is an inorganic metal oxide used as fine particles, with optical performance driven by crystal form, particle size, dispersion quality, and surface treatment. Typical color and opacity use can range from low single digits to much higher levels in complexion products, while sunscreen use is regulated by region and often sits in the several-percent range depending on the protection target.
