Industrial Applications
This sulfate salt is primarily employed as a building block in the synthesis of oxidative hair colorants, where it contributes to the formation of stable, long-lasting chromophores through coupling reactions with couplers under alkaline conditions. Its use ensures consistent color development and improved formulation stability compared to free-base amines.
- Serves as a reliable precursor in cosmetic dye manufacturing
- Offers improved solubility and reduced volatility versus free p-phenylenediamine
- Meets stringent quality thresholds for trace metals and moisture-sensitive applications
Stored in a cool, well-ventilated area away from oxidizing agents, 1,4-Diaminobenzene Sulfate is typically supplied in 25 kg fiber drums or customized packaging per client specifications. As a non-formulated intermediate, it is intended exclusively for industrial synthesis and not for direct consumer use.
