Yellow 5 (Ci 19140)
Ingredient Info
Yellow 5 is a synthetic colorant (also called Tartrazine) used to give skincare products a yellow or golden hue. It serves purely cosmetic purposes to make products visually appealing and has no active skincare benefits.
Potential concerns
- May cause allergic reactions or sensitivity in some individuals, particularly those with aspirin sensitivity or existing dye sensitivities
- Can trigger itching, redness, or contact dermatitis in sensitive skin
- Potential cross-reactivity in people with sensitivity to other azo dyes
Science: Yellow 5 is approved for cosmetic use in most regions (EU, US FDA) and has a long safety history. However, it remains one of the more commonly reported colorant allergens in cosmetic products, with documented cases of adverse reactions in sensitive populations.
