Carbon Black/Ci 77266 ●
TL;DR. This ingredient is used as an insoluble dark colorant, mainly in eye makeup, mascara, eyeliner, nail products, and some rinse-off products. It gives high opacity and strong shade depth at low loading.
What does Carbon Black/Ci 77266 do in a cosmetic formula?
This ingredient is used as an insoluble dark colorant, mainly in eye makeup, mascara, eyeliner, nail products, and some rinse-off products. It gives high opacity and strong shade depth at low loading.
Is Carbon Black/Ci 77266 clean?
From a clean-beauty perspective, it carries friction because quality depends on tight control of combustion-derived impurities, especially polycyclic aromatic residues. Some standards and retailers restrict it, particularly in powders or sprays where inhalation exposure is relevant.
Is Carbon Black/Ci 77266 sustainable?
This material is typically made by high-temperature combustion or thermal decomposition of fossil feedstocks. It is not biodegradable in the usual organic-molecule sense, although it is largely inert and insoluble in finished products.
Is Carbon Black/Ci 77266 COSMOS-approved?
It is generally not aligned with COSMOS-natural or COSMOS-organic formulation principles because it is a synthetic, combustion-derived pigment rather than a minimally processed mineral or renewable material. Its Green Chemistry profile is limited by fossil sourcing, energy-intensive manufacture, and persistence as a particulate.
How does Carbon Black/Ci 77266 work chemically?
The molecule is not a discrete molecule, but an elemental, graphitic particulate made of fused nanoscale primary particles aggregated into larger pigment structures. It is chemically stable across normal cosmetic pH ranges, insoluble in water and oils, and must be well dispersed and purity-controlled for residues and respirable particle considerations.
