DISPERSE RED 11

Description

Disperse Red 11, also known as C.I. Disperse Red 11 or Solvent Red 179, is a synthetic azo dye commonly used in the cosmetic and personal care industry, particularly in hair coloring products. This vibrant red colorant is prized for its ability to impart rich, long-lasting hues to hair without causing significant damage to the hair shaft.

The molecular structure of Disperse Red 11 allows it to penetrate the hair cuticle effectively, resulting in more uniform and intense color distribution. It exhibits excellent color fastness, resisting fading from washing, UV exposure, and environmental factors. This dye is particularly suitable for semi-permanent and demi-permanent hair color formulations.

Disperse Red 11 is often combined with other dyes to create a wide range of red and auburn shades. It performs well in various hair coloring formats, including creams, gels, and foams. While generally considered safe for use in hair dyes, it's important to note that some individuals may experience allergic reactions. As with all hair colorants, patch testing is recommended before full application to ensure compatibility with the user's skin and hair.
