About N-Phenyl-P-Phenylenediamine
N-Phenyl-P-Phenylenediamine is an aromatic amine.[1] In cosmetics, it is used to color hair.[4] In Europe, it may be used only as a coloring ingredient in oxidative hair dyes.[2] It is described as a solid with no pronounced odor, so when used in solid form, it is important to dissolve or evenly disperse it first to prevent clumping in the formula.[3]
