CI 15865

Description

CI 15865, also known as Red 36 or D&C Red No. 36, is a synthetic azo dye commonly used in cosmetics and personal care products. This vibrant red pigment is oil-soluble and provides a rich, warm color to various formulations. It is particularly effective in lipsticks, blushes, and other color cosmetics where a deep red hue is desired.

The pigment's molecular structure allows for excellent color stability and resistance to fading, making it a reliable choice for long-wearing makeup products. CI 15865 is approved by the FDA for use in cosmetics and externally applied drugs, but it is not permitted for use in products applied to the eye area or in applications that may come into contact with mucous membranes.

While generally considered safe for topical use, some individuals may experience skin sensitization or allergic reactions. As with any colorant, patch testing is recommended before widespread application. Formulators should be aware of regulatory limits on concentration and usage across different global markets. When incorporating CI 15865 into skincare or cosmetic formulations, it's essential to consider its interaction with other ingredients and its impact on the overall product stability and performance.
