The quest for vibrant and long-lasting hair color often leads us to explore the science behind the products we use. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing the essential chemical building blocks that make these transformations possible. Today, we focus on m-aminophenol sulfate, more specifically known as 3-Aminophenol Hemisulfate, a critical intermediate in the formulation of permanent hair dyes. Its unique chemical properties allow for the permanent alteration of hair color, making it an indispensable ingredient in the beauty industry. Understanding the chemical properties of 3-aminophenol sulfate is key to appreciating its role.

3-Aminophenol Hemisulfate (CAS No: 68239-81-6) is a chemical compound with the molecular formula C12H16N2O6S. It is typically supplied as an off-white powder and possesses a melting point range of 122-123°C. In the context of hair dyes, it functions as a dye intermediate or precursor. This means it’s not the final colorant itself, but rather a molecule that reacts with other compounds, such as developers (like hydrogen peroxide) and couplers, within the hair shaft to form the desired color. The process is intricate: the precursors penetrate the hair cuticle, and under oxidative conditions, they combine to create larger color molecules that are trapped inside the hair, resulting in permanent color. The reliable performance of these reactions is why the uses of 3-aminophenol sulfate in cosmetics are so targeted and important.

The effectiveness of permanent hair dyes relies heavily on the quality of their constituent ingredients. This is where the importance of high purity, typically ≥99.0%, for 3-Aminophenol Hemisulfate comes into play. Brands that source this compound from NINGBO INNO PHARMCHEM CO.,LTD. can be assured of its quality, with strict controls on ash content (≤1.0%), moisture (≤1.0%), and minimal iron content (≤40ppm). These specifications ensure that the intermediate will react predictably, leading to consistent and beautiful color results for consumers. When exploring hair dye ingredients m-aminophenol sulfate, formulators look for these markers of quality to guarantee product performance and safety. The reliable application of 3-aminophenol sulfate in permanent dyes hinges on these precise chemical standards.

The demand for sophisticated hair coloring solutions continues to grow, and with it, the need for high-performance chemical intermediates. 3-Aminophenol Hemisulfate plays a crucial role in meeting this demand by enabling the creation of a wide spectrum of permanent hair colors. Whether a brand is aiming for subtle highlights or dramatic transformations, the foundational chemistry provided by intermediates like this is essential. NINGBO INNO PHARMCHEM CO.,LTD. is proud to supply this vital component, supporting the innovation and quality that consumers expect from their hair care products. For any manufacturer seeking to produce premium hair dyes, understanding and sourcing quality chemical intermediates for hair dyes m-aminophenol sulfate is a fundamental step towards achieving success in the competitive market.
