HC BLUE NO. 8

Description

HC Blue No. 8 is a semi-permanent hair dye ingredient widely used in the cosmetic industry for its ability to impart a vibrant blue hue to hair. This synthetic colorant belongs to the class of HC (Hair Color) dyes, specifically designed for use in hair coloring products. HC Blue No. 8 is known for its excellent color payoff and longevity compared to temporary dyes.

The molecule structure of HC Blue No. 8 allows it to penetrate the hair shaft partially, resulting in a color that lasts through multiple washes. It is particularly effective on pre-lightened or naturally light hair, producing intense blue shades. This dye is often combined with other HC dyes to create various blue-based tones and shades.

HC Blue No. 8 is approved for use in hair coloring products in many countries, including the European Union, where it is regulated under Annex III of the EU Cosmetics Regulation. It is important to note that while generally safe for use in hair dyes, some individuals may experience allergic reactions. Patch testing is recommended before full application to ensure compatibility with the user's skin and hair.
