CI 44045

Description

CI 44045, also known as Blue 4 or Brilliant Blue FCF, is a synthetic colorant widely used in cosmetics and personal care products. This water-soluble dye belongs to the triarylmethane family and imparts a vibrant blue hue to various formulations. Its molecular structure allows for excellent stability across a wide pH range, making it versatile for use in diverse skincare and cosmetic applications.

In skincare formulations, CI 44045 is primarily utilized for its color-imparting properties, particularly in products like moisturizers, serums, and cleansers where a blue tint is desired. The dye is approved by regulatory bodies such as the FDA and European Commission for use in cosmetics and personal care items, with established safety guidelines.

While CI 44045 does not offer direct skincare benefits, its role in product aesthetics can enhance user experience and product appeal. It is often combined with other colorants to achieve specific shades or create visually striking effects in cosmetic formulations. However, as with any synthetic dye, some individuals may experience sensitivity or allergic reactions, necessitating patch testing before widespread use in products intended for sensitive skin.
