What is the main ingredient in aniline derivative tint?

Explanation:
Oxidative hair color using aniline-derived precursors relies on an oxidizing agent to form the actual color molecules. Hydrogen peroxide acts as the developer that oxidizes the dye precursors, allowing them to couple and form the durable pigment that stays in the hair. Water is simply the solvent in which everything is dispersed. Ammonia or other alkalizing agents may be included to raise pH and help the color penetrate, but they aren’t the component that develops the color. Sodium hydroxide isn’t the typical main ingredient in this tint.
