1-HEXYL 4,5-DIAMINO PYRAZOLE SULFATE

Description

1-Hexyl 4,5-diamino pyrazole sulfate is a synthetic hair dye ingredient primarily used in permanent hair coloring formulations. This compound belongs to the pyrazole family of dyes, known for their ability to produce vibrant and long-lasting color results. As an oxidative hair dye precursor, it reacts with hydrogen peroxide to form larger color molecules within the hair shaft.

This ingredient is particularly effective in creating warm brown to red shades, depending on the other dye precursors present in the formulation. Its molecular structure allows for optimal penetration into the hair cortex, ensuring even color distribution and improved gray coverage. The sulfate form of this compound enhances its solubility in aqueous solutions, facilitating easier incorporation into hair dye products.

When used in hair coloring formulations, 1-hexyl 4,5-diamino pyrazole sulfate typically comprises 0.1% to 3% of the total product composition. It is often combined with other dye precursors and coupling agents to achieve a wide range of color possibilities. While generally considered safe for use in hair dyes, patch testing is recommended to check for potential allergic reactions in sensitive individuals.
