HC YELLOW NO. 13

Description

HC Yellow No. 13 is a synthetic hair dye ingredient primarily used in semi-permanent and demi-permanent hair coloring products. This molecule belongs to the azo dye family and is known for its ability to impart vibrant yellow to golden hues to hair. HC Yellow No. 13 is particularly effective in creating warm blonde shades and enhancing highlights in lighter hair colors.

The compound exhibits good color fastness and stability, allowing for longer-lasting results compared to some other temporary dyes. It penetrates the hair shaft moderately, providing color that gradually fades over multiple washes. HC Yellow No. 13 is often combined with other dye molecules to achieve a wide range of blonde, brown, and red shades.

In terms of safety, HC Yellow No. 13 has been evaluated by regulatory bodies and is approved for use in hair dye formulations within specified concentration limits. However, as with many hair dye ingredients, it may cause allergic reactions in some individuals. Patch testing is recommended before use to minimize the risk of adverse reactions. When formulating with HC Yellow No. 13, it's essential to consider its compatibility with other ingredients and its optimal pH range for maximum color efficacy.
