CI 42080

Description

CI 42080, also known as Brilliant Blue FCF or FD&C Blue No. 1, is a synthetic blue dye widely used in cosmetics and personal care products. This water-soluble colorant belongs to the triarylmethane family of dyes and is prized for its vibrant hue and stability across a range of pH levels.

In skincare formulations, CI 42080 is primarily utilized for its coloring properties, imparting a striking blue shade to various products such as shampoos, soaps, and lotions. Its molecular structure allows for excellent dispersion in aqueous solutions, ensuring uniform color distribution throughout the product.

The safety profile of CI 42080 has been extensively studied, and it is approved by regulatory bodies including the FDA and EU for use in cosmetics and food products. It demonstrates low skin irritation potential and minimal risk of sensitization when used at recommended concentrations.

Formulators should be aware that CI 42080 can interact with certain ingredients, particularly cationic compounds, which may affect color intensity or stability. It is also sensitive to strong reducing agents and prolonged exposure to light, factors that should be considered during product development and packaging design to maintain color integrity throughout the product's shelf life.
