P-PHENYLENE DIAMINE SULFATE (PPDS)

P-Phenylenediamine Sulfate (PPD Sulfate) is an organic compound commonly used in hair dyes and hair coloring products. It is a derivative of P-Phenylenediamine (PPD), which is a primary aromatic amine.

Description: P-Phenylenediamine Sulfate is a fine crystalline powder.

Applications:

1. Hair Dyes: PPD Sulfate is a key component in many oxidative hair dyes. It reacts with hydrogen peroxide to form colored products that penetrate the hair shaft, resulting in a long-lasting and vibrant hair color.

2. Textile Dyes: It is also used in the textile industry as a dye for various fabrics and materials.

3. Analytical Chemistry: PPD Sulfate is employed in analytical chemistry for the determination of certain chemicals.

It's important to note that PPD and its derivatives like PPD Sulfate can cause allergic reactions in some individuals, leading to skin sensitization and irritation. Therefore, its use in hair dyes and other products is regulated, and patch tests are often recommended to check for potential allergies before application.
