Question 1

What does CI 77491 / CI 77499 / CI 77492 do in a cosmetic formula?

Accepted Answer

This ingredient is a colorant pigment used to create red, yellow, black, and blended brown tones in makeup, sunscreens, and tinted skin care. It also adds opacity and helps adjust shade depth in complexion products.

Question 2

Is CI 77491 / CI 77499 / CI 77492 clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well tolerated because it is insoluble, non-fragrant, and not a common sensitizer. The main quality issue is pigment purity, especially trace heavy-metal limits set by cosmetic regulations and clean-standard programs.

Question 3

Is CI 77491 / CI 77499 / CI 77492 sustainable?

Accepted Answer

This material is mineral-based and may be mined or manufactured to cosmetic purity, with synthetic routes often used for consistency and lower contaminant variability. It is not biodegradable in the organic-matter sense, but it is inert, non-bioaccumulative, and not associated with aquatic persistence concerns in the same way as many synthetic polymers or UV filters.

Question 4

Is CI 77491 / CI 77499 / CI 77492 COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic products when it meets the standard’s criteria for approved mineral colorants and impurity limits. Its Green Chemistry fit is strongest on stability, low reactivity, and low irritation, while its renewable-feedstock score is limited because it is inorganic and mineral-derived.

Question 5

How does CI 77491 / CI 77499 / CI 77492 work chemically?

Accepted Answer

This ingredient is an inorganic, insoluble pigment made of crystalline metal-oxygen lattices, with different crystal forms producing red, yellow, and black shades. It is pH-stable, heat-stable, and used as needed for shade matching, often from below 1% in lightly tinted products to much higher levels in foundations, concealers, and pressed powders.
