What does PPD mean?
Para-Phenylenediamine (PPD) or p-Phenylenediamine is a chemical compound that is widely used as a chromophoric ingredient in oxidative hair dyes, permanent hair dyes that rely on chemical reactions called oxidation to fix the color.
PPD reacts with hydrogen peroxide or with other chemicals to bind the color to the hair permanently. PPD is part of a class of chemicals called aromatic amines, which are found in the plastic and chemical industries as byproducts of manufacturing. In addition to hair dyes, it is used in the manufacturing of rubber and certain polymers, such as Kevlar and Twaron. It is also used as a developing agent in the color photographic film development process.
