Question 1

What does CI 77266 do in a cosmetic formula?

Accepted Answer

This ingredient is an insoluble black pigment used to give formulas deep color and opacity, especially in mascara, liner, nail color, and pigmented complexion products. It does not preserve, cleanse, or moisturize, it mainly changes visual payoff.

Question 2

Is CI 77266 clean?

Accepted Answer

From a clean-beauty perspective, this ingredient carries scrutiny because certain grades can contain trace combustion byproducts, and airborne respirable particles are treated more cautiously than bound pigments in creams, pencils, or pressed products. High-purity cosmetic grades are regulated with impurity limits and are generally better accepted when not used in sprays or loose powders.

Question 3

Is CI 77266 sustainable?

Accepted Answer

Conventional supply is usually fossil-derived and made through high-temperature controlled combustion, so it is not a renewable-feedstock material. It is highly persistent as an inert particulate and is not expected to biodegrade, although it is typically used at low levels and remains bound in finished matrices.

Question 4

Is CI 77266 COSMOS-approved?

Accepted Answer

It is generally not aligned with COSMOS-organic or COSMOS-natural standards unless a specific compliant grade is documented by the supplier. Its Green Chemistry fit is weak because it is nonrenewable, energy-intensive to produce, and not biodegradable, despite being chemically inert in many finished formulas.

Question 5

How does CI 77266 work chemically?

Accepted Answer

It is not a discrete molecule, it is an insoluble particulate colorant made of fused, graphitic domains with very high optical absorption. In the EU, regulated nano grades are limited to 10% and are not for products that may expose the lungs by inhalation; finished-formula stability is mainly dispersion-dependent rather than pH-dependent.
