CI 19140

TL;DR. This ingredient is a synthetic colorant used to give products a bright yellow shade. It has no primary skin or hair benefit beyond visual appearance and shade correction.

What does CI 19140 do in a cosmetic formula?

This ingredient is a synthetic colorant used to give products a bright yellow shade. It has no primary skin or hair benefit beyond visual appearance and shade correction.

Is CI 19140 clean?

Clean-beauty standards often restrict or exclude this type of synthetic azo colorant, especially in products positioned as naturally derived. It can be associated with sensitivity in a small subset of users, so it tends to create clean-standard friction even when legally permitted for cosmetic use.

Is CI 19140 sustainable?

This material is typically petroleum-derived and made through multi-step synthetic chemistry. It is water-soluble and used at very low levels, but it is not a strong fit for renewable sourcing or readily biodegradable design.

Is CI 19140 COSMOS-approved?

It is not permitted in COSMOS organic or COSMOS natural products because it is a synthetic colorant outside the standard’s allowed colorant categories. From a Green Chemistry perspective, it has weak alignment due to fossil-derived feedstocks, multi-step synthesis, and limited biodegradability.

How does CI 19140 work chemically?

The molecule is a water-soluble monoazo dye, usually present as a salt with sulfonate groups that improve aqueous solubility. It is typically used at very low levels, often in the ppm range up to about 0.1% depending on product type and regulation, and it can fade or shift with strong oxidizers, reducing agents, or incompatible charged ingredients.
