CI 19140[3][1] ●
TL;DR. This ingredient is a synthetic colorant used to give formulas a yellow shade. It is most common in rinse-off products, oral care, and some leave-on products where water-soluble color is needed.
What does CI 19140[3][1] do in a cosmetic formula?
This ingredient is a synthetic colorant used to give formulas a yellow shade. It is most common in rinse-off products, oral care, and some leave-on products where water-soluble color is needed.
Is CI 19140[3][1] clean?
From a clean-beauty perspective, it has more friction than simple mineral or plant-derived colorants because it is a synthetic dye and can be a sensitivity trigger for a small subset of users. It is allowed in conventional cosmetics under color-additive rules and purity specifications, but many clean standards restrict or do not include it.
Is CI 19140[3][1] sustainable?
This material is typically made from petrochemical feedstocks through multi-step synthetic chemistry. It is water soluble, but synthetic dye chemistry raises wastewater-treatment and biodegradation concerns compared with simpler naturally derived colorants.
Is CI 19140[3][1] COSMOS-approved?
It is not generally permitted under COSMOS-natural or COSMOS-organic standards because it is a synthetic colorant outside the standard’s allowed natural-origin colorant approach. Its fit with Green Chemistry is limited by nonrenewable feedstocks and dye-manufacturing wastewater controls, even though it is used at very low levels.
How does CI 19140[3][1] work chemically?
The molecule is a water-soluble synthetic azo dye, usually present as a salt with sulfonate groups that help it disperse evenly in aqueous systems. Typical use is very low, often around 0.001% to 0.1% or as needed for shade, and it can be affected by strong oxidizing or reducing systems.
