Yellow 5 (Ci 19140 ●
TL;DR. This ingredient is a synthetic colorant used to give formulas a bright it hue, especially in water-based products, gels, cleansers, and rinse-off items.
What does Yellow 5 (Ci 19140 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give formulas a bright it hue, especially in water-based products, gels, cleansers, and rinse-off items.
Is Yellow 5 (Ci 19140 clean?
From a clean-beauty perspective, it has friction because many standards restrict synthetic colorants even when they meet cosmetic purity specifications. It is generally used at very low levels, but it can be associated with rare sensitivity reactions in susceptible users.
Is Yellow 5 (Ci 19140 sustainable?
This material is typically made from petrochemical-derived aromatic intermediates rather than renewable feedstocks. It is water-soluble, and its environmental profile depends heavily on wastewater treatment because synthetic dyes can show limited biodegradation.
Is Yellow 5 (Ci 19140 COSMOS-approved?
This ingredient is not permitted in COSMOS-certified natural or organic cosmetics because it is a synthetic colorant outside the allowed colorant set. Its fit with Green Chemistry is weak due to nonrenewable sourcing and limited biodegradability.
How does Yellow 5 (Ci 19140 work chemically?
The molecule is a water-soluble synthetic azo dye, usually supplied as a sodium salt with sulfonate groups that keep it compatible with aqueous systems. It is typically used only as needed for shade adjustment, often at trace to very low levels, and formulators check color stability against pH, light exposure, oxidizers, and reducing agents.
