Description

Para Amino Phenol (PAP), chemically known as 4-Aminophenol, is one of the most widely used oxidative hair dye intermediates in the professional and consumer cosmetics industry. As a primary coupler and developer base, it plays a central role in achieving a broad spectrum of hair colour shades — from warm browns and rich blacks to vibrant fashion tones.

Role in Hair Dyeing When combined with an oxidizing agent such as hydrogen peroxide, PAP undergoes oxidative coupling with dye couplers to form large, stable colour molecules that penetrate deep into the hair cortex. This results in long-lasting, fade-resistant colour that withstands repeated washing. Its excellent compatibility with p-Phenylenediamine (PPD) and other dye intermediates makes it a cornerstone ingredient in permanent and semi-permanent hair colour formulations.

⚠️ Note: Para Amino Phenol is a regulated cosmetic ingredient. Formulations must comply with applicable regulations including EU Cosmetics Regulation (EC) No. 1223/2009, CDSCO guidelines in India, and relevant BIS standards. Always include appropriate patch test instructions on finished product labelling.

Step 1 – Prepare Your Base Dissolve PAP in a warm alkaline solution (pH 9–10) using distilled water. Adding a small amount of sodium sulfite (0.1–0.5%) helps prevent premature oxidation and extends shelf life of the formulation.



Step 2 – Combine with Dye Couplers Mix PAP with your chosen dye couplers (e.g., resorcinol, m-aminophenol, or 2-naphthol) in the required ratio to achieve the target shade. Typical PAP-to-coupler ratio is 2:1 to 3:1 depending on the desired colour depth.



Step 3 – Add Alkaline Carrier Incorporate into an ammonia or ethanolamine-based cream or gel base. Maintain pH between 9.0 – 10.5 for optimal oxidative coupling during application.



Step 4 – Mix with Oxidant at Point of Use Just before application, mix the colour cream with a barium peroxide developer (typically 3% – 6% / 10–20 vol) in a 1:1 or 1:1.5 ratio. Apply immediately after mixing.



Step 5 – Application



Apply evenly to dry or slightly damp hair using an applicator brush

Leave on for 25–45 minutes depending on desired colour intensity and grey coverage

Rinse thoroughly with lukewarm water, then shampoo and condition



⚠️ Safety Reminders



Always conduct a 48-hour patch test before use

Use gloves during formulation and application

Store PAP in a cool, dry, airtight container away from light and moisture
