CI 42045

Description

CI 42045, also known as Blue 1 or Brilliant Blue FCF, is a synthetic colorant widely used in cosmetics and personal care products. This water-soluble dye imparts a vibrant blue hue to various formulations, including skincare products, makeup, and hair care items. Its molecular structure allows for excellent stability in a wide range of pH levels and in the presence of light, making it a reliable choice for color-sensitive applications.

In skincare formulations, CI 42045 is primarily utilized for its aesthetic properties, enhancing the visual appeal of products without significantly affecting their functional performance. It is often found in cleansers, toners, and masks, where a blue tint is desired. The ingredient has undergone extensive safety assessments and is approved by regulatory bodies such as the FDA and EU Commission for use in cosmetics.

While CI 42045 is generally well-tolerated, some individuals may experience sensitivity or allergic reactions. As with any colorant, patch testing is recommended for those with sensitive skin or a history of allergies. It's important to note that this ingredient serves a purely cosmetic function and does not provide any direct skincare benefits beyond its role as a colorant.
