Ci 42051
What Ci 42051 is & what it does
CI 42051 is a synthetic colorant, also known as Patent Blue, used to give cosmetic products a blue or blue-green tint. Its sole role in a formula is aesthetic: it adjusts the visible color of the product and contributes nothing to skin performance. It is used at very small amounts, since strong dyes develop their shade at low concentrations. Color additives like this one are regulated for cosmetic use, and it appears in a range of rinse-off and leave-on products.
