CI 19140 / Yellow 5 Lake]

TL;DR. This ingredient is an insoluble colorant used to give cosmetics a bright, consistent it hue, especially in powders, pressed makeup, lip products, and emulsions where a dispersed pigment is preferred over a water-soluble dye.

What does CI 19140 / Yellow 5 Lake] do in a cosmetic formula?

This ingredient is an insoluble colorant used to give cosmetics a bright, consistent it hue, especially in powders, pressed makeup, lip products, and emulsions where a dispersed pigment is preferred over a water-soluble dye.

Is CI 19140 / Yellow 5 Lake] clean?

From a clean-beauty perspective, it is a common point of friction because many clean standards restrict synthetic colorants, even when they are legally permitted and purity-controlled. Sensitivity is uncommon for most users, but color-additive compliance and trace impurity limits are central to its review.

Is CI 19140 / Yellow 5 Lake] sustainable?

This material is synthetically produced, typically from petrochemical feedstocks, and then converted into an insoluble pigment form on a mineral substrate. It has weaker sustainability alignment than plant- or mineral-derived colorants because biodegradability is limited and wastewater controls matter during manufacture.

Is CI 19140 / Yellow 5 Lake] COSMOS-approved?

It is not permitted under COSMOS natural or organic standards because it is a synthetic organic colorant rather than an allowed natural, mineral, or nature-derived color source. Its Green Chemistry fit is limited by nonrenewable feedstocks, multi-step synthesis, and persistence concerns relative to simpler biodegradable materials.

How does CI 19140 / Yellow 5 Lake] work chemically?

The molecule is a synthetic sulfonated monoazo colorant converted into an insoluble aluminum-based pigment, which improves dispersion in oils, waxes, powders, and emulsions compared with the soluble dye form. Use is typically governed by color-additive regulations and purity specifications rather than a universal cosmetic percentage, and formulators need to check regional permissions by product area, including eye-area and lip-use rules.
