2,5,6-TRIAMINO-4-PYRIMIDINOL SULFATE

Description

2,5,6-Triamino-4-pyrimidinol sulfate is a synthetic compound with significant applications in hair care formulations. This versatile ingredient functions primarily as a hair dye precursor, playing a crucial role in the development of permanent hair coloring products. Its chemical structure allows it to penetrate the hair shaft and react with other dye components to create long-lasting color results.

In hair dye formulations, 2,5,6-triamino-4-pyrimidinol sulfate acts as a coupling agent, interacting with oxidative dyes to produce a wide range of color shades. It is particularly effective in creating warm brown and red tones. The sulfate form of this compound enhances its stability and solubility in aqueous solutions, making it easier to incorporate into various hair dye formulations.

This ingredient is typically used in concentrations ranging from 0.1% to 2%, depending on the desired color intensity and the overall formulation. It is often combined with other dye precursors and developers to achieve optimal color results. While generally considered safe for use in hair dyes, it is important to note that some individuals may experience sensitivity or allergic reactions. As with all hair dye ingredients, patch testing is recommended before full application.
