The hair dye industry is a dynamic sector, constantly seeking to innovate and improve product performance. Central to these advancements are the chemical intermediates used in formulations. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of these vital components, including 3-Aminophenol Sulfate, also known as 3-Aminophenol Hemisulfate. This compound is fundamental to the creation of permanent hair colors, contributing significantly to the depth, longevity, and vibrancy that consumers expect. Understanding its precise function within complex formulations is key to appreciating modern hair dye technology.

3-Aminophenol Hemisulfate, identified by CAS No: 68239-81-6, with the molecular formula C12H16N2O6S, acts as a crucial precursor in oxidative hair dyeing processes. Unlike direct dyes that simply coat the hair shaft, oxidative dyes penetrate the hair and form color molecules internally. This process requires specific chemical intermediates that can react safely and effectively. 3-Aminophenol Hemisulfate, often supplied as an off-white powder with a melting point of 122-123°C, is meticulously manufactured to meet stringent purity standards (≥99.0% HPLC). This high purity ensures predictable chemical reactions, which is essential for achieving consistent color outcomes. The uses of 3-aminophenol sulfate in cosmetics are therefore highly specialized, focusing on its performance as a reactive dye precursor.

The quality of ingredients directly impacts the final product’s success. For 3-Aminophenol Hemisulfate, manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. adhere to strict specifications. These include low ash content (≤1.0%), low moisture (≤1.0%), and minimal iron (≤40ppm). These controls are vital because impurities can disrupt the delicate oxidative dyeing process, leading to inconsistent color results or potential stability issues. When brands are looking to purchase reliable 3-aminophenol sulfate, these technical details are critical for ensuring the development of advanced hair dye formulations. The consistent quality of these hair dye ingredients m-aminophenol sulfate allows formulators to fine-tune shades and ensure long-lasting color retention.

The chemical properties of 3-aminophenol sulfate are what make it so valuable in hair color chemistry. It's a building block that, when combined with other dye precursors and hydrogen peroxide, creates a spectrum of permanent colors. The process allows for the creation of shades that are resistant to fading and washing. The meticulous control over the application of 3-aminophenol sulfate in permanent dyes ensures that these color molecules are formed efficiently and securely within the hair structure. NINGBO INNO PHARMCHEM CO.,LTD. is committed to supplying intermediates that meet the high standards of the cosmetic industry, enabling brands to push the boundaries of hair color innovation and provide consumers with safe, effective, and beautiful results. The careful selection and sourcing of chemical intermediates for hair dyes m-aminophenol sulfate are fundamental to achieving these goals.
