4-ETHOXY-M-PHENYLENEDIAMINE

Description

4-Ethoxy-m-phenylenediamine is a synthetic compound primarily used in hair dye formulations. This aromatic diamine serves as a key component in permanent hair coloring products, contributing to the development of various shades, particularly in the brown to black spectrum. The molecule's structure allows it to penetrate the hair shaft and react with oxidizing agents, forming larger color molecules that remain trapped within the hair cuticle.

This ingredient is known for its ability to produce long-lasting color results and provide good coverage for gray hair. It works synergistically with other dye precursors to create a wide range of color possibilities. However, like many hair dye compounds, 4-ethoxy-m-phenylenediamine can potentially cause allergic reactions in some individuals. As a result, patch tests are recommended before use to assess skin sensitivity.

In the context of hair dye formulations, this compound is typically used in concentrations ranging from 0.5% to 3%, depending on the desired color intensity and shade. It is often combined with hydrogen peroxide or other oxidizing agents to activate the coloring process. Proper handling and usage guidelines should be followed to ensure safe application and optimal results in hair coloring products.
