THE STORY OF CHEMKG INTERMEDIATE PPD
Chemkg Intermediate PPD: The High-Performance Dye Base for Deep, Lasting Color
Chemkg Intermediate PPD is a powerful aromatic amine widely used as a primary oxidation dye in permanent and long-lasting hair-color systems. Known for producing intense, durable color, it forms the backbone of many professional hair-dye formulations, delivering strong pigment development and excellent grey coverage.
Engineered Through Precision Chemical Synthesis
Chemkg Intermediate PPD is produced through carefully controlled chemical synthesis involving the reduction of nitrobenzene derivatives, followed by purification, drying, and stabilization. Each batch undergoes strict quality testing for purity, reactivity, and consistency — essential for predictable and safe color performance in regulated cosmetic applications.
A Strong, Reliable Color Developer for Professional Hair Dye
In cosmetics, Chemkg Intermediate PPD acts as a primary oxidation dye.
It reacts with hydrogen peroxide and couplers to produce deep, rich brown and black tones with excellent longevity. Chemkg Intermediate PPD provides exceptional grey coverage, color intensity, and resistance to fading — making it a cornerstone ingredient in permanent and semi-permanent hair-color technology.
Potent, Regulated, and Designed for Controlled Use Only
Used only in oxidative hair-dye formulations under regulated conditions.
Typical usage: very low — usually <1% in the final hair-color mixture after oxidation.
Must be handled using appropriate protective equipment and stored tightly sealed in cool, dry conditions.
Chemkg Intermediate PPD is strictly regulated worldwide, requiring patch testing and compliance with cosmetic safety guidelines to ensure consumer protection and responsible formulation.
