General Description
CHEMKG INTERMEDIATE PPD (Paraphenylene Diamine, or PPD) is a colorless to light brown crystalline compound commonly used as a key intermediate in the production of hair dyes and other oxidative colorant formulations. As a strong reducing agent, it plays a crucial role in the development of long-lasting, vibrant colors in permanent hair coloring systems. CHEMKG INTERMEDIATE PPD is known for its ability to react with various couplers in the presence of oxidizing agents (like hydrogen peroxide) to form complex, stable pigments. Despite its effectiveness, CHEMKG INTERMEDIATE PPD is regulated due to its potential for skin sensitivity and irritation.
Uses in the Cosmetics Industry
CHEMKG INTERMEDIATE PPD is primarily utilized in the cosmetic industry for the following purposes:
- Used as a core ingredient in oxidative hair colorants, where it reacts with other chemicals to produce a wide range of permanent hair colors, particularly dark shades.
- Works alongside developers (such as hydrogen peroxide) in hair dye systems to form the final desired color upon application.
- Used in conjunction with other intermediates and couplers to create custom hair color shades with precise undertones and intensities.
Due to its significant role in permanent hair dye formulations, CHEMKG INTERMEDIATE PPD is purchased in bulk by manufacturers and cosmetic formulators creating salon-grade and retail hair color products.
Hazards
While CHEMKG INTERMEDIATE PPD is highly effective as a colorant, it is associated with several potential hazards:
- CHEMKG INTERMEDIATE PPD is a known sensitizer and can cause allergic reactions, skin irritation, or dermatitis, especially with prolonged exposure. It is recommended to use it within the safe limits and perform patch testing prior to use.
- Direct contact with eyes can cause significant irritation or damage. It is crucial to avoid eye contact during application.
- Can be harmful if swallowed or inhaled. CHEMKG INTERMEDIATE PPD should be handled with care to prevent ingestion or inhalation of dust.
- It is one of the most common allergens in hair dye products, and individuals sensitive to PPD may experience severe reactions, including swelling or breathing difficulties.
Storage & Stability
- Store in a cool, dry place in tightly sealed containers to prevent oxidation and degradation of the compound.
- Stable under normal conditions, but exposure to light and air should be minimized to avoid degradation. It should be stored away from food and drink to prevent contamination.
CHEMKG INTERMEDIATE PPD is available for wholesale purchase by manufacturers, with stringent quality control standards to ensure the safe incorporation of this ingredient in regulated cosmetic formulations.
