Ci 19140/Yellow 5 ●
TL;DR. This ingredient is a synthetic colorant used to give products a yellow hue or adjust the shade of a formula. It is most common in water-based products such as cleansers, gels, shampoos, and color-variant cosmetics.
What does Ci 19140/Yellow 5 do in a cosmetic formula?
This ingredient is a synthetic colorant used to give products a yellow hue or adjust the shade of a formula. It is most common in water-based products such as cleansers, gels, shampoos, and color-variant cosmetics.
Is Ci 19140/Yellow 5 clean?
From a clean-beauty perspective, this ingredient often faces scrutiny because it is a synthetic dye and may appear on retailer restricted lists or require tighter purity controls. It is regulated for cosmetic use in many markets, but sensitivity reactions can occur in a small subset of users.
Is Ci 19140/Yellow 5 sustainable?
This material is typically made from petrochemical feedstocks and is not a strong fit for renewable sourcing goals. It is water-soluble and used at low levels, but synthetic dyes can be slow to break down in wastewater without adequate treatment.
Is Ci 19140/Yellow 5 COSMOS-approved?
This ingredient is not permitted in COSMOS-natural or COSMOS-organic formulations because it is a synthetic colorant outside the allowed colorant set. Its Green Chemistry profile is limited by petrochemical sourcing and modest biodegradability, although its high color strength keeps use levels low.
How does Ci 19140/Yellow 5 work chemically?
The molecule is a water-soluble monoazo dye, usually supplied as a salt, with sulfonate groups that support dispersion in aqueous systems rather than oils. It is typically used at very low, shade-dependent levels, often around trace amounts to below 0.1%, and formulas must account for regulatory color-additive purity requirements by market.
