  • Description

General Description:

Para-Aminophenol (also known as 4-Aminophenol, p-Aminophenol, or PAP) is an organic compound with the formula H₂NC₆H₄OH. It appears as a white to slightly pink crystalline solid but can darken upon exposure to air and light. It has both amine (-NH₂) and hydroxyl (-OH) functional groups positioned para (opposite) to each other on a benzene ring. Para-Aminophenol is a key intermediate in organic synthesis, particularly valued for its role in dye, pharmaceutical, and chemical manufacturing.

Uses in the Cosmetic Industry

Para-Aminophenol is primarily used as an oxidative hair dye intermediate. It helps develop darker shades (especially browns and blacks) when combined with other dye precursors and oxidizing agents like hydrogen peroxide.
Occasionally used in products requiring color deposition on hair or eyelashes, where oxidative dyes are involved.

  • How it Works:
  • In oxidative hair coloring, Para-Aminophenol reacts during the dyeing process to form complex colored molecules that bind to the hair fiber, resulting in long-lasting color.

Hazard Information

Para-Aminophenol can cause irritation upon direct contact with skin or eyes. It may lead to redness, itching, or inflammation.
It is a known sensitizer, meaning it can trigger allergic reactions (like contact dermatitis) after repeated exposure.
Inhalation of dust or ingestion can be harmful, causing symptoms like headache, dizziness, or more severe toxic effects at higher doses.
At high exposure levels, it can cause methemoglobinemia — a blood disorder where oxygen delivery to tissues is impaired.
Usage in cosmetics is strictly regulated. In the EU, it is restricted under Annex III of the EU Cosmetics Regulation (Regulation (EC) No 1223/2009), meaning it can only be used under specific concentration limits and with certain warnings on the product label.

Safety Measures:

Formulators must ensure strict control of concentrations and provide appropriate instructions for safe use (like wearing gloves during application). Patch tests are often recommended before consumer use.

THE STORY OF PARA-AMINOPHENOL

Para-Aminophenol: The Core Dye Intermediate Behind Rich, Lasting Color

Para-Aminophenol (p-Aminophenol) is an essential aromatic compound widely used as a key intermediate in oxidative hair-dye systems. Known for its ability to develop deep, long-lasting color shades, it provides controlled reactivity, strong coloration performance, and compatibility with modern dye-formulation technologies.

Manufactured Through Precision Chemical Synthesis

Para-Aminophenol is produced through carefully controlled chemical synthesis involving the reduction of nitrophenol derivatives, followed by purification and crystallization. Each batch undergoes stringent refining and quality checks to ensure high purity and consistency—crucial for predictable color development in cosmetic dye applications.

A Powerful Color-Developing Agent for Oxidative Hair Dye Systems

In cosmetics, Para-Aminophenol functions as a primary intermediate in oxidative hair-color formulations.
It reacts with couplers and hydrogen peroxide to create rich browns, blacks, and natural tone variations. Its strong color-yield capabilities enable precise shade creation, predictable pigment formation, and long-lasting coverage—especially in permanent and semi-permanent hair dyes.

High-Performance Dye Ingredient with Strict Safety Compliance

Used exclusively in oxidative hair-dye formulations under controlled conditions.
Typical usage: very low — usually <1% in the finished formulation after oxidation.
Store tightly sealed in a cool, dry place, and handle with proper protective equipment.
Regulated globally, Para-Aminophenol must be used according to cosmetic safety guidelines to ensure consumer protection and product consistency.

Formulator’s Queries, We Answered


Para Aminophenol (PAP) is an organic chemical compound commonly used as an intermediate in hair dyes and colorants for the personal care industry. It offers strong coloring performance and stability when formulated properly.


The CAS number of Para Aminophenol is 123-30-8.


The INCI (International Nomenclature of Cosmetic Ingredients) name for Para Aminophenol is p-Aminophenol.


Para Aminophenol is primarily used in oxidative hair dye formulations. It acts as a color-developing agent when combined with other intermediates and oxidizers to produce a wide range of shades.


When used within the recommended concentration limits and under proper regulatory guidelines, Para Aminophenol is considered safe. However, it must be carefully formulated, as it can cause skin sensitivity or allergic reactions in some individuals.


Yes, the use of Para Aminophenol in personal care products is regulated by authorities like the European Union (EU Cosmetic Regulation), the US FDA, and others. It is important to follow concentration limits and mandatory labeling for consumer safety.


Since Para Aminophenol is a synthetic chemical, it is generally not permitted in certified natural or organic cosmetic products. Brands focusing on natural claims should consider alternative colorants.


Formulators should use protective gear, ensure proper ventilation, and adhere to recommended usage levels. Testing for stability and potential sensitization is crucial during product development.


Para Aminophenol typically appears as white to slightly pinkish crystals or powder. It is moderately soluble in water and alcohol, and it tends to oxidize upon exposure to air.
