CI 45380

Description

CI 45380, also known as D&C Red No. 22 or Eosin YS, is a synthetic red dye widely used in cosmetics and personal care products. This water-soluble colorant belongs to the xanthene class of dyes and is characterized by its bright pink to red hue. CI 45380 is approved by the FDA for use in cosmetics and drugs, including those applied to mucous membranes.

In skincare formulations, CI 45380 is primarily utilized for its coloring properties, imparting a vibrant pink or red shade to products such as lipsticks, blushes, and nail polishes. Its molecular structure allows for excellent color stability and uniformity in various cosmetic bases. The dye exhibits good light fastness, ensuring that products maintain their intended color over time.

While generally considered safe for topical use, some individuals may experience sensitivity or allergic reactions to CI 45380. As with all colorants, it's crucial to use this ingredient within the recommended concentration limits set by regulatory bodies. Formulators should be aware that CI 45380 may stain the skin temporarily and should consider this when developing rinse-off products. In certain formulations, it may also interact with other ingredients, potentially affecting product stability or performance.
