Question 1

What does CI 77499) do in a cosmetic formula?

Accepted Answer

This ingredient is a black mineral pigment used to deepen shade, adjust undertone, and provide opacity in color cosmetics, sunscreens, and tinted skin products. It is insoluble, so formulators disperse it rather than dissolve it.

Question 2

Is CI 77499) clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well tolerated and not a major restricted-list concern. The main quality issue is pigment purity, especially tight control of trace heavy metals under cosmetic colorant specifications.

Question 3

Is CI 77499) sustainable?

Accepted Answer

This material is usually made from abundant mineral or industrial feedstocks rather than harvested biomass. It is not biodegradable because it is inorganic, but it is insoluble, stable, and not considered a persistence concern in the same way as many synthetic organic pollutants.

Question 4

Is CI 77499) COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s criteria for approved mineral colorants and contaminant limits. Its Green Chemistry fit is strongest on stability, low reactivity, and low use-level impact, and weaker on renewability because it is not bio-based.

Question 5

How does CI 77499) work chemically?

Accepted Answer

This compound is an inorganic crystalline pigment built from transition-metal cations in an oxygen lattice, giving strong black color through light absorption rather than dye-like solubility. Typical use can range from trace shade adjustment below 1% to several percent or more in makeup, and it is heat-, light-, and pH-stable but needs good dispersion and wetting to prevent specking or settling.
