CI 45190

Description

CI 45190, also known as Acid Blue 9 or FD&C Blue No. 1, is a synthetic blue dye commonly used in cosmetics and personal care products. This water-soluble colorant belongs to the triarylmethane family of dyes and is approved by the FDA for use in various applications, including skincare formulations.

In skincare products, CI 45190 serves primarily as a colorant, imparting a vibrant blue hue to formulations. It is often used in small quantities to adjust the color of products or to create visually appealing effects. The dye is particularly stable in a wide pH range, making it suitable for diverse formulations.

While generally considered safe for topical use, some individuals may experience skin irritation or allergic reactions. It's important to note that CI 45190 is not recommended for use around the eye area in the European Union due to potential risks.

From a formulation perspective, CI 45190 is compatible with most skincare ingredients and can be incorporated into various product types, including lotions, creams, and serums. However, its intense color means that precise dosing is crucial to achieve the desired aesthetic effect without overpowering the product's appearance.
