Descriptif
CI 42090, also known as Blue 1 or Brilliant Blue FCF, is a synthetic colorant used to give products a vivid blue shade. You’ll find it in everything from cleansers, shampoos, conditioners, and body washes to makeup, bath products, and even some foods. It doesn’t treat skin or hair or change their condition; its job is purely cosmetic, helping a formula look more appealing, more recognizable, or more on-brand. In blends, it can also be mixed with yellow dyes such as Tartrazine to create green tones.
For skincare and haircare users, CI 42090 is mainly about aesthetics. It can make a shampoo look fresh and “clean,” give a gel cleanser a bright jewel tone, or add color to a lip product or eye product. People who enjoy colorful, playful formulas may appreciate it, especially in rinse-off products where the dye is less likely to linger. Because it is a color additive rather than an active ingredient, it offers no moisturizing, soothing, or strengthening benefits on its own.
Caveat: as with any synthetic dye, some people prefer to avoid it due to personal preference, sensitivity concerns, or a desire for simpler ingredient lists. If you know you react to colored cosmetics or fragranced products, it’s worth checking the full formula and patch testing new products when possible. Otherwise, CI 42090 is generally just there to make the product look blue.
