Ortho Phenylene Diamine

Ortho-Phenylenediamine is an aromatic diamine compound widely used as an intermediate in oxidative hair dye formulations.
It appears as a white to pale yellow crystalline solid that can darken upon exposure to air and light.
The ingredient is primarily used to produce natural-looking brown, black, and dark shade hair colors in permanent hair dyes.
It functions by reacting with oxidizing agents such as hydrogen peroxide to form colored dye molecules inside the hair shaft.
Ortho-Phenylenediamine is commonly used in combination with other dye precursors to create a wide range of hair color shades.
It is also used in certain textile and chemical synthesis applications as an intermediate compound.
The ingredient provides strong color intensity, good durability, and effective gray hair coverage.
It is regulated in cosmetic applications due to potential skin sensitization concerns.
Typical usage levels are strictly controlled according to cosmetic safety standards and formulation guidelines.
The material should be stored in tightly sealed containers away from heat, moisture, and light exposure.
