CI 19140/YELLOW 5 LAKE. CI 42090/BLUE 1 LAKE ●
TL;DR. This ingredient is a synthetic colorant used to tint formulas, often creating a green-toned shade when dispersed in opaque, pressed, or anhydrous products. Its insoluble particulate form helps color stay suspended in powders, balms, and decorative cosmetics.
What does CI 19140/YELLOW 5 LAKE. CI 42090/BLUE 1 LAKE do in a cosmetic formula?
This ingredient is a synthetic colorant used to tint formulas, often creating a green-toned shade when dispersed in opaque, pressed, or anhydrous products. Its insoluble particulate form helps color stay suspended in powders, balms, and decorative cosmetics.
Is CI 19140/YELLOW 5 LAKE. CI 42090/BLUE 1 LAKE clean?
From a clean beauty perspective, this ingredient is a legally regulated color additive when batch-certified and used within regional rules, but many clean frameworks restrict synthetic petroleum-derived colorants. Sensitivity reports are uncommon at cosmetic exposure, although eye-area and lip-use permissions depend on jurisdiction.
Is CI 19140/YELLOW 5 LAKE. CI 42090/BLUE 1 LAKE sustainable?
This material is synthetically made from nonrenewable feedstocks and converted into an insoluble particulate colorant. It is not designed for ready biodegradation, so its sustainability profile is weaker than plant-derived or simple mineral colorants.
Is CI 19140/YELLOW 5 LAKE. CI 42090/BLUE 1 LAKE COSMOS-approved?
This ingredient is not permitted in COSMOS-natural or COSMOS-organic products because the standard limits colorants to approved natural, nature-derived, or mineral options. Its Green Chemistry fit is limited by nonrenewable feedstocks, multistep synthesis, and limited biodegradability.
How does CI 19140/YELLOW 5 LAKE. CI 42090/BLUE 1 LAKE work chemically?
Chemically, it is a blend of synthetic anionic dye molecules converted into insoluble metal-salt pigments on an alumina hydrate substrate, which makes it more dispersible in oils, waxes, and powders than soluble dye forms. Use level is driven by shade target and regional color-additive rules rather than one fixed percentage, and it is generally stable in dry or anhydrous systems but can bleed or shift in strongly acidic, alkaline, or highly aqueous formulas.
