HC RED NO. 17

Description

HC Red No. 17 is a synthetic hair dye molecule widely used in semi-permanent and temporary hair coloring products. This vibrant red pigment belongs to the azo dye family and is known for its ability to impart rich, warm red tones to hair without the need for a developer or oxidizing agent. HC Red No. 17 is particularly effective on pre-lightened or naturally light hair, producing hues ranging from intense cherry red to softer auburn shades.

The compound is appreciated for its color longevity compared to other semi-permanent dyes, typically lasting through 6-8 washes before significant fading occurs. It is often combined with other HC dyes to create custom color blends and achieve a wide spectrum of red-based shades. HC Red No. 17 has a relatively low molecular weight, allowing it to penetrate the hair shaft for improved color retention.

While generally considered safe for use in hair coloring products, some individuals may experience skin sensitivity. As with all hair dyes, a patch test is recommended before full application. HC Red No. 17 is approved for use in hair dye formulations in many countries, including those in the European Union, with specific concentration limits.
