2,6-DIAMINO-3-((PYRIDIN-3-YL)AZO)PYRIDINE

Description

2,6-Diamino-3-((pyridin-3-yl)azo)pyridine is a synthetic compound primarily used in hair coloring formulations. This molecule belongs to the azo dye family, characterized by its nitrogen-nitrogen double bond (N=N) that connects two aromatic rings. The compound's structure allows it to effectively bind to hair keratin, providing long-lasting color results.

In hair dye applications, 2,6-diamino-3-((pyridin-3-yl)azo)pyridine typically imparts warm, reddish tones to the hair. Its molecular composition enables it to penetrate the hair shaft, interacting with the melanin pigments present in the cortex. This interaction results in a color change that can withstand multiple washes and environmental factors.

The ingredient demonstrates good stability in various hair dye formulations, including permanent, semi-permanent, and temporary color products. It is often used in combination with other dye molecules to achieve a wide range of hues and color depths. While effective in coloring, it's important to note that like many synthetic dyes, this compound may cause allergic reactions in some individuals. Patch testing is recommended before use in hair coloring products to ensure compatibility with the user's skin and scalp.
