In the intricate world of cosmetic chemistry, understanding the precise properties of each ingredient is fundamental to creating effective and high-performing products. For hair dye manufacturers, intermediates like HC Yellow 7 are critical, and their chemical and physical characteristics directly influence the final shade, longevity, and overall quality of the hair color. NINGBO INNO PHARMCHEM CO.,LTD provides essential chemical intermediates, and this article focuses on the key properties of HC Yellow 7 and their significance.

HC Yellow 7, identified by its CAS number 104226-21-3, is a synthetic azo dye used as an intermediate in hair coloring. Its molecular formula is C17H22N4O2, and it has a molecular weight of 314.38200. These fundamental chemical descriptors are vital for formulators when calculating stoichiometric ratios and predicting interactions within a complex hair dye mixture. The structure of HC Yellow 7 inherently provides the capacity to impart a yellow hue to hair.

Beyond its molecular composition, the physical properties of HC Yellow 7 are equally important for practical application. It typically presents as an orange powder, a form that is convenient for handling and incorporation into liquid or cream-based formulations. Crucially, its purity, usually measured at ≥99.0% via HPLC, ensures that the color deposited is consistent and free from impurities that could compromise performance or safety. Manufacturers looking to buy HC Yellow 7 powder often prioritize these high purity standards.

Several other physical properties are relevant for understanding HC Yellow 7's behavior during formulation and storage. Its density is listed as 1.2. While specific melting point data might not be readily available, its boiling point is recorded at 578.8°C, and its flash point at 303.8°C. These figures provide insights into its thermal stability and safe handling conditions. For instance, a high flash point indicates that the substance is not highly flammable under normal conditions. The refractive index of 1.603 further characterizes its optical properties.

The performance of HC Yellow 7 in hair dyes is directly linked to these properties. High purity ensures predictable color intensity and shade. The chemical structure allows for effective penetration into the hair shaft, contributing to semi-permanent or sometimes more lasting color effects depending on the overall formulation. When sourcing from a reliable HC Yellow 7 supplier like NINGBO INNO PHARMCHEM CO.,LTD, manufacturers can be confident in the consistency of these properties, which translates to reliable product performance. This focus on detailed chemical specifications allows cosmetic companies to effectively purchase HC Yellow 7 and integrate it seamlessly into their product development cycles.

NINGBO INNO PHARMCHEM CO.,LTD’s commitment to quality extends to providing comprehensive data on chemical intermediates like HC Yellow 7. Understanding these properties is key for any formulator aiming to create innovative and effective hair coloring solutions that meet consumer demands for both vibrancy and safety.
