4,5-DIAMINO-1-((4-CHLOROPHENYL)METHYL)-1H-PYRAZOLE-SULFATE

Description

4,5-Diamino-1-((4-chlorophenyl)methyl)-1H-pyrazole-sulfate is a synthetic compound primarily used in hair coloring products. This ingredient functions as an oxidative hair dye precursor, playing a crucial role in the development of permanent hair color formulations. When combined with an oxidizing agent, typically hydrogen peroxide, it undergoes a chemical reaction that produces colored molecules within the hair shaft.

The compound's structure allows it to penetrate the hair cuticle and react with other dye precursors to create a range of color tones, particularly in the brown to black spectrum. Its molecular composition enables it to form stable color complexes that resist fading and washing, contributing to the longevity of the hair color.

In hair dye formulations, 4,5-diamino-1-((4-chlorophenyl)methyl)-1H-pyrazole-sulfate is often used in combination with other dye precursors and coupling agents to achieve desired shades and color intensity. This ingredient is subject to regulatory guidelines regarding its concentration in finished products to ensure safety and minimize the risk of adverse reactions. As with all oxidative hair dyes, patch testing is recommended before use to check for potential allergic reactions.
