HC YELLOW NO. 8

Description

HC Yellow No. 8 is a synthetic hair dye compound primarily used in semi-permanent and temporary hair coloring products. This ingredient imparts a vibrant yellow hue to hair and is often combined with other dyes to create various shades and tones. As a direct dye, HC Yellow No. 8 does not require oxidation to develop its color, making it suitable for gentler hair coloring formulations.

This dye molecule has a relatively low molecular weight, allowing it to penetrate the hair shaft and adhere to the cuticle. Its color fastness is moderate, typically lasting through several washes before gradually fading. HC Yellow No. 8 is particularly effective on pre-lightened or naturally light hair, producing more intense results on these base shades.

In hair care formulations, HC Yellow No. 8 is often used in conjunction with conditioning agents to minimize potential drying effects. While generally considered safe for use in cosmetics, some individuals may experience allergic reactions. As with all hair dyes, a patch test is recommended before use. Formulators should be aware of regulatory limitations on concentration levels in different regions when incorporating HC Yellow No. 8 into hair coloring products.
