HC YELLOW NO. 11

Description

HC Yellow No. 11, also known as 3-Nitro-p-hydroxyethylaminophenol, is a semi-permanent hair dye ingredient widely used in the cosmetic industry. This synthetic colorant imparts vibrant yellow to golden hues to hair, making it a popular choice for highlighting and creating warm tones. HC Yellow No. 11 is particularly effective in coloring gray or light-colored hair, offering longer-lasting results compared to temporary dyes.

As a direct dye, HC Yellow No. 11 does not require an oxidizing agent to develop its color, allowing for gentler application processes. It penetrates the hair shaft, adhering to the cortex to provide color that gradually fades over multiple washes. This ingredient is often combined with other HC dyes to create a broader spectrum of shades and achieve desired color results.

While HC Yellow No. 11 is approved for use in hair coloring products in many countries, it's important to note that some individuals may experience sensitivity or allergic reactions. As with all hair dyes, a patch test is recommended before full application to ensure compatibility with the user's skin and hair. Regular deep conditioning treatments can help maintain the vibrancy of color achieved with HC Yellow No. 11.
