For businesses operating within the cosmetics and personal care sector, particularly those focused on hair coloring products, the procurement of high-quality intermediates is paramount. One such critical ingredient is 2,5-Diaminoanisole Sulfate (CAS: 66671-82-7), a compound essential for creating permanent hair dyes that offer vibrant, long-lasting colors. Understanding the market and identifying reliable manufacturers and suppliers is key to maintaining product quality and competitive edge. This guide aims to assist procurement managers and R&D scientists in navigating the complexities of sourcing this vital component.

Understanding the Role of 2,5-Diaminoanisole Sulfate in Hair Dyes

2,5-Diaminoanisole Sulfate functions as a primary intermediate in oxidative hair dye formulations. Its chemical structure allows it to react with coupling agents under oxidizing conditions, leading to the formation of stable color molecules within the hair shaft. This process is responsible for achieving a wide spectrum of shades, from deep blacks to subtle blondes, and ensuring color longevity and resistance to washing. The demand for such intermediates is consistently driven by the global cosmetics market, which constantly seeks innovative and effective hair coloring solutions.

Key Specifications and Quality Considerations for Buyers

When evaluating potential suppliers, it is crucial to focus on product specifications that guarantee performance and safety. For 2,5-Diaminoanisole Sulfate, high purity is a non-negotiable factor. Manufacturers typically aim for a purity level of ≥99.0% as determined by High-Performance Liquid Chromatography (HPLC). Other critical specifications include low ash content (≤0.5%), controlled moisture levels (≤4.0%), and minimal iron content (≤20 ppm). These parameters directly influence the consistency and efficacy of the final hair dye product. A reputable manufacturer will provide detailed Certificates of Analysis (CoA) for each batch, ensuring transparency and accountability.

Navigating the Supply Chain: Choosing a Reliable Manufacturer and Supplier

The global chemical landscape offers numerous options for sourcing 2,5-Diaminoanisole Sulfate. China, in particular, has emerged as a major hub for chemical production, housing many competitive manufacturers and suppliers. When looking to buy this intermediate, consider the following:

  • Production Capacity and Scalability: Ensure the supplier can meet your current and future volume requirements.
  • Quality Control Systems: Verify their adherence to international quality standards and their internal quality assurance processes.
  • Technical Support: A good supplier will offer technical assistance regarding product application, handling, and formulation.
  • Regulatory Compliance: Confirm that their products comply with relevant regional and international regulations for cosmetic ingredients.
  • Competitive Pricing: While quality is key, it is also important to secure favorable price terms. Compare quotes from multiple reputable suppliers.
