The global demand for innovative and effective hair color products continues to grow, placing significant importance on the quality and reliability of the chemical intermediates used in their production. 2-Amino-6-chloro-4-nitrophenol (CAS No. 6358-09-4) is a critical component for many hair dye formulations, prized for its coloring properties and chemical stability. For procurement managers and R&D scientists in the cosmetics sector, understanding the specifications and securing a dependable supply chain for this ingredient is vital. If you are looking to buy this chemical, this guide outlines key considerations. As a leading manufacturer, we ensure you find a quality product.

Understanding the Product: Appearance and Purity

2-Amino-6-chloro-4-nitrophenol is typically supplied as an orange-yellow powder. The molecular formula C6H5ClN2O3 highlights its specific chemical makeup, which is engineered for performance in color applications. A paramount factor for formulators is the purity of this intermediate, with high standards often requiring a minimum of 99.0% as verified by HPLC. This level of purity is essential for predictable batch-to-batch consistency in hair dye manufacturing, ensuring that the final product achieves the intended color shade and performance without unwanted side effects from impurities. When you choose to buy this ingredient, always request and verify the Certificate of Analysis (CoA) from your supplier.

Applications in Hair Dye Formulations

The versatility of 2-Amino-6-chloro-4-nitrophenol makes it a valuable asset in the hair color industry. It functions effectively in two primary ways:

  • Direct Dye: In semi-permanent hair color formulations, it acts as a direct dye, imparting color without requiring an oxidative process. This makes formulations simpler and potentially gentler.
  • Oxidative Dye Precursor: In permanent hair dyes, it serves as a key intermediate that reacts with an oxidizing agent (like hydrogen peroxide) and other dye precursors. This reaction occurs within the hair shaft, forming larger color molecules that are locked in for long-lasting results. Its stability during these oxidative reactions is a significant benefit.

For companies aiming to buy this chemical, understanding these applications helps in formulating a wide range of shades, from natural tones to fashion colors.

Regulatory Compliance and Safety

The cosmetic industry operates under strict regulatory frameworks designed to protect consumer health. 2-Amino-6-chloro-4-nitrophenol has been evaluated for safety by various international bodies. For instance, its use in hair dyes is permitted, but typically at maximum concentrations, such as 2.0% in finished products, as determined by expert panels like the CIR. European Union regulations also specify its permissible use and concentration limits. Manufacturers who buy this ingredient must ensure their product formulations adhere to these guidelines to meet legal and safety standards. Working with a supplier who can provide documentation confirming compliance is crucial for your purchasing decisions.

The Strategic Advantage of a China-Based Manufacturer

For many cosmetic companies, sourcing chemical intermediates from China offers significant strategic advantages, including competitive pricing and access to large-scale production capabilities. When looking to buy 2-Amino-6-chloro-4-nitrophenol, partnering with a reputable China-based manufacturer ensures a stable supply chain, consistent quality, and often, more favorable cost structures. A reliable supplier will offer robust quality control, transparent documentation, and efficient logistics to support your global operations. Prioritizing these aspects when you buy will ensure that your hair dye production is both cost-effective and reliable.

In conclusion, 2-Amino-6-chloro-4-nitrophenol is a vital ingredient for hair dye manufacturers. By focusing on sourcing high-purity material from compliant and reliable suppliers, especially those in China, businesses can ensure the quality and consistency of their hair color products, driving innovation and consumer satisfaction.
