2,6-DIAMINOPYRIDINE SULFATE

Description

2,6-Diaminopyridine Sulfate is a potent hair dye ingredient widely used in permanent hair coloring products. This synthetic compound is primarily employed as an oxidative hair dye precursor, playing a crucial role in creating long-lasting dark shades, particularly black and brown hues. When combined with hydrogen peroxide, it undergoes a chemical reaction that produces color molecules within the hair shaft.

The sulfate form of this compound enhances its solubility and stability in hair dye formulations. It penetrates the hair cuticle effectively, allowing for deep and even color distribution. 2,6-Diaminopyridine Sulfate is known for its excellent color retention properties, resulting in vibrant and fade-resistant hair color.

While effective, this ingredient requires careful handling due to its potential for skin sensitization. Proper patch testing is recommended before use. In formulations, it is typically combined with other dye precursors and coupling agents to achieve a wide range of color possibilities. Its concentration in hair dye products is regulated by cosmetic authorities to ensure safety and efficacy in consumer use.
