DIRECT RED 23

Description

Direct Red 23, also known as CI 29160, is a synthetic azo dye widely used in the cosmetic and personal care industry, particularly in haircare products. This vibrant red colorant is prized for its ability to impart intense, long-lasting color to hair dyes and temporary hair coloring products. The molecule's structure allows it to penetrate the hair shaft, providing a more permanent coloration compared to surface-level dyes.

In hair dye formulations, Direct Red 23 is often combined with other dyes to create a spectrum of red and auburn shades. Its stability in various pH environments makes it suitable for use in both acidic and alkaline hair coloring systems. The dye exhibits good resistance to washing and environmental factors, contributing to color longevity.

While effective as a colorant, it's important to note that Direct Red 23 may cause allergic reactions in some individuals. Patch testing is recommended before use. Additionally, this dye is not approved for use in products that come into contact with mucous membranes or in the eye area. Formulators must adhere to regulatory guidelines regarding concentration limits in hair dye products to ensure consumer safety.
