HC ORANGE NO. 3

Description

HC Orange No. 3, also known as 2-Nitro-4'-hydroxyethylaminophenol, is a semi-permanent hair dye ingredient widely used in the cosmetic industry. This synthetic colorant provides vibrant orange to reddish-orange hues and is particularly effective in darker hair shades. HC Orange No. 3 penetrates the hair shaft, depositing color molecules that adhere to the cortex, resulting in longer-lasting color compared to temporary dyes.

This compound is typically used in concentrations ranging from 0.5% to 3% in hair coloring formulations. It is often combined with other HC dyes to create a spectrum of warm tones. HC Orange No. 3 is compatible with various hair types and can be incorporated into both professional and at-home coloring products.

While generally considered safe for use in hair dyes, some individuals may experience skin sensitization or allergic reactions. Patch testing is recommended before application. HC Orange No. 3 is not approved for use around the eye area or in products that may come into contact with mucous membranes. Proper formulation and usage guidelines are essential to ensure product safety and optimal color results.
