At NINGBO INNO PHARMCHEM CO.,LTD, we appreciate the intricate chemistry that underpins cosmetic product performance. Today, we focus on HC Yellow No. 13, a compound whose chemical name, 2-(2-nitro-4-trifluoromethylphenylamino)ethanol, reveals key structural elements that make it a vital hair dye intermediate. Understanding this chemistry is crucial for formulators seeking effective hair coloring agent solutions.

The presence of a trifluoromethyl group (-CF3) attached to a phenyl ring in the molecule is particularly noteworthy. This electron-withdrawing group can significantly influence the electronic properties of the molecule, affecting its coloristic properties and stability. Combined with the nitro group and the aminoethanol portion, this structure is finely tuned for its intended use in hair dyes. This intricate design ensures that trifluoromethyl phenylamino ethanol hair dye components perform reliably.

The CAS number 10442-83-8 serves as a universal reference point for this chemical. Its physical form, a yellow crystalline powder, and its high purity (typically ≥99.0% HPLC) underscore its suitability for cosmetic applications where consistency and safety are paramount. Manufacturers rely on such precisely defined hair dye formulation ingredients to guarantee the quality of their final products.

The role of HC Yellow No. 13 extends beyond simply providing a yellow hue. Its chemical structure contributes to the dye's substantivity to hair fibers and its compatibility with other components in a hair dye formulation. This makes it a cornerstone ingredient for achieving both the visual appeal and the performance characteristics expected from high-quality hair color products. It is a prime example of how specific chemical structures lead to specialized applications.

NINGBO INNO PHARMCHEM CO.,LTD is proud to supply HC Yellow No. 13, enabling formulators to leverage its unique chemical attributes. By understanding the science behind this hair dye intermediate, cosmetic chemists can continue to innovate and create products that meet the ever-evolving demands of the beauty industry. The pursuit of vibrant and lasting color relies on the precise application of such advanced chemical compounds.
