HC BLUE NO. 13

Description

HC Blue No. 13 is a semi-permanent hair dye molecule widely used in the cosmetic industry for its vibrant blue coloration properties. This synthetic compound belongs to the family of HC dyes, which are designed to penetrate the hair shaft and provide longer-lasting color compared to temporary dyes. HC Blue No. 13 is particularly effective in creating cool-toned blue shades and is often used in combination with other dyes to achieve various hues.

The chemical structure of HC Blue No. 13 allows it to form weak bonds with hair proteins, resulting in a color that gradually fades over multiple washes. This dye is suitable for use on pre-lightened or naturally light hair, as it does not contain ammonia or peroxide and cannot lift or lighten hair color on its own. HC Blue No. 13 is generally considered safe for use in hair coloring products when formulated and applied according to regulatory guidelines.

It's important to note that, like other semi-permanent dyes, HC Blue No. 13 may cause temporary staining of the scalp and skin. Patch testing is recommended before use to check for potential allergic reactions or sensitivities.
