P-PHENYLENEDIAMINE SULFATE

Description

P-Phenylenediamine Sulfate, commonly known as PPD Sulfate, is a crucial hair dye ingredient widely used in permanent and semi-permanent hair coloring products. This synthetic organic compound is a derivative of p-phenylenediamine, modified with sulfuric acid to enhance its stability and solubility. PPD Sulfate functions as a primary intermediate in oxidative hair dyes, reacting with hydrogen peroxide to create larger, colored molecules that adhere to the hair shaft.

The ingredient is particularly effective in covering gray hair and producing dark shades, ranging from brown to black. Its molecular structure allows it to penetrate the hair cortex, ensuring long-lasting color results. PPD Sulfate is known for its ability to withstand multiple washes and resist fading, making it a preferred choice in professional hair coloring formulations.

While effective, PPD Sulfate can cause allergic reactions in some individuals. Patch testing is recommended before use to identify potential sensitivities. Manufacturers often combine it with other dye precursors and couplers to achieve a wide spectrum of hair colors. When used as directed, PPD Sulfate provides consistent, vibrant, and durable hair coloration results.
