CI 12085 is a synthetic colorant used in cosmetics for its ability to impart an orangish-reddish hue to the products. It is also known as Pigment Red 4 or Red 36. This dye can be found in products like lipsticks, nail polishes, eyeshadows, hair colors, and skin care. Further, CI 12085 is a monoazo color, chemically known as 1-[(2-Chloro-4-nitrophenyl)azo]-2-naphthol. It is important to note that over the years this colorant has raised some safety concerns for users as well as the environment. Therefore, its usage is regulated and is added to cosmetic formulations in limited quantities.

What is CI 12085 used for?
CI 12085 is a vibrant red hue employed in a variety of products, including lipsticks, blushes, nail polishes, and eyeshadows, to impart a rich, appealing color. The dye is valued for its stability and non-bleeding properties, ensuring that the color remains vibrant and consistent throughout the product's shelf life.

Overall, this colorant is best for achieving the desired red shades in long-lasting cosmetics.
Origin
CI 12085 is made through a series of chemical reactions beginning with the nitration of 2-naphthol, followed by sulfonation to introduce sulfonic acid groups. These intermediates are then diazotized and coupled with various aromatic compounds to form the final pigment. Additionally, CI 12085 is filtered, washed, and dried to obtain quality colorant suitable for use in cosmetics.
