HC RED NO. 13

Description

HC Red No. 13, also known as 1-Amino-4-(2-hydroxyethyl)amino-2-nitrobenzene, is a synthetic hair dye ingredient widely used in the cosmetic industry. This semi-permanent colorant is particularly effective in creating vibrant red and burgundy hair shades. HC Red No. 13 penetrates the hair shaft, depositing color molecules that adhere to the cortex, resulting in long-lasting color that gradually fades over time.

This dye is favored for its ability to provide intense color without the use of harsh oxidative agents, making it a gentler option for hair coloring. It is often incorporated into various hair coloring products, including temporary color rinses, semi-permanent dyes, and some permanent hair color formulations. HC Red No. 13 works well in combination with other dye molecules to create a range of red-based hues.

While generally considered safe for use in hair dyes, some individuals may experience skin sensitivity or allergic reactions. As with all hair dyes, a patch test is recommended before full application. HC Red No. 13 is regulated by cosmetic authorities in many countries, with specific concentration limits set for its use in hair coloring products.
