CI 28440

Description

CI 28440, also known as Brilliant Blue FCF or FD&C Blue No. 1, is a synthetic water-soluble dye widely used in cosmetics and personal care products. This vibrant blue colorant belongs to the triphenylmethane family of dyes and is approved for use in various applications by regulatory bodies worldwide, including the FDA and EU Commission.

In skincare formulations, CI 28440 imparts a distinctive blue hue to products such as shampoos, body washes, and facial cleansers. Its excellent stability across a wide pH range and resistance to light, heat, and oxidation make it a versatile choice for formulators. The dye exhibits good solubility in water and glycols, allowing for easy incorporation into aqueous-based products.

While primarily used for its coloring properties, CI 28440 has been studied for potential antimicrobial effects, though more research is needed to confirm these benefits in skincare applications. It's important to note that this ingredient may cause allergic reactions in some individuals, particularly those with sensitivities to synthetic dyes. As with any colorant, patch testing is recommended before widespread use in cosmetic formulations to ensure compatibility with different skin types.
