In the dynamic world of cosmetic chemistry, understanding the specific properties of each ingredient is paramount. HC Blue No. 11, identified by its CAS number 23920-15-2, stands out as a significant compound within the hair dye industry. Its chemical name, 2-[N-(2-hydroxyethyl)-4-(2-methoxyethylamino)-3-nitroanilino]ethanol, provides a detailed insight into its molecular structure, which is crucial for its function as a hair colorant intermediate. This detailed understanding is vital for manufacturers seeking to leverage its capabilities effectively and safely.

The molecular formula, C13H21N3O5, and a molecular weight of approximately 299.32300, further define HC Blue No. 11. These precise chemical specifications are not merely academic; they directly influence how the compound behaves in formulations. For instance, its physical properties, such as a density of 1.323 and a boiling point of 538.371°C, dictate handling procedures and storage requirements in industrial settings. The requirement for a minimum purity of ≥99.0% by HPLC is a testament to the industry's commitment to quality, ensuring that the final hair dye products are both effective and safe for consumers.

The primary application of HC Blue No. 11 lies in its role as a direct dye for hair. It is incorporated into formulations to impart specific color characteristics, contributing to the vast spectrum of shades available in the market. Whether used in temporary or semi-permanent hair color systems, its consistent performance is highly valued. The knowledge of its ash content (≤1.0%) and loss on drying (≤1.0%) also informs formulators about the stability and handling of the raw material, ensuring that moisture levels do not compromise its efficacy. The strict specifications for iron content (≤100ppm) further highlight the meticulous approach taken in producing high-grade cosmetic ingredients.

When considering the purchase of HC Blue No. 11, understanding its packaging, typically in 25 kg/drum, and the possibility of custom packaging, is essential for logistics and inventory management. The recommendation to store it in a cool, ventilated place ensures its stability and longevity. By adhering to these guidelines, manufacturers can ensure that HC Blue No. 11 remains a reliable component in their product lines.
