CI 19140 (Yellow 5)
Ingredient Info
CI 19140, commonly known as Yellow 5 or Tartrazine, is a synthetic colorant used to give skincare products a yellow or golden hue. It serves no active skincare benefit and is purely for visual appeal and product identification.
Potential concerns
- May cause allergic reactions or sensitivity in individuals with tartrazine sensitivity
- Can trigger reactions in people with aspirin sensitivity or certain food dyes intolerances
- Not suitable for those with dye sensitivities or color additive restrictions
Science: Yellow 5 is approved for cosmetic use in most major regulatory bodies (FDA, EU) at specified concentrations. Limited peer-reviewed data exists on its direct effects in skincare formulations, though it is well-established as a colorant. The primary concern is allergic sensitization in susceptible populations rather than toxicity at typical cosmetic levels.
