N,N-DIETHYL-P-PHENYLENEDIAMINE SULFATE

Description

N,N-Diethyl-p-phenylenediamine sulfate is a synthetic compound commonly used in hair coloring formulations. This versatile ingredient functions as a primary intermediate in oxidative hair dyes, playing a crucial role in the development of various hair color shades.

The compound is characterized by its ability to penetrate the hair shaft and react with oxidizing agents, typically hydrogen peroxide, to form larger color molecules. This reaction results in the creation of permanent hair color that resists washing and fading. N,N-Diethyl-p-phenylenediamine sulfate is particularly effective in producing warm brown and red tones in hair dye formulations.

In its pure form, this ingredient appears as a white to off-white crystalline powder. It is soluble in water and alcohol, making it easy to incorporate into various hair dye preparations. While effective for coloring, it's important to note that N,N-Diethyl-p-phenylenediamine sulfate can cause skin sensitization in some individuals. As such, patch testing is recommended before use, and it should only be used in formulations designed for professional application or carefully formulated at-home hair coloring products.
