The quest for vibrant and enduring hair color is a cornerstone of the cosmetic industry. Behind every stunning shade lies a complex interplay of chemical components, each with a specific role. Among these, 2,4-Diaminophenoxyethanol sulfate (CAS 70643-20-8) is a key player, acting as a vital coupler in oxidative hair dyeing systems. For those looking to understand the efficacy of this ingredient or seeking to buy 2,4-diaminophenoxyethanol sulfate, a closer look at its chemistry is insightful.

Molecular Structure and Reactivity

2,4-Diaminophenoxyethanol sulfate is an aromatic amine derivative. Its molecular structure, featuring two amine groups and a phenoxyethanol moiety, dictates its reactivity. The presence of these functional groups makes it an ideal coupler in oxidative hair dye formulations. In these systems, the compound undergoes oxidation and coupling reactions. When exposed to an oxidizing agent like hydrogen peroxide, the amine groups become highly reactive. They then couple with oxidized primary intermediates (dye precursors) to form complex, colored molecules. These molecules are significantly larger than the precursors, which prevents them from easily escaping the hair shaft, thus ensuring the color's longevity and wash-fastness.

The specific arrangement of the amino groups on the benzene ring, along with the hydroxyl-terminated ethyl chain, contributes to the spectrum of colors that can be achieved when this coupler is used in combination with different primary intermediates. This versatility makes it a preferred ingredient for formulators aiming to create a wide palette of shades.

Purity and Performance: The Manufacturer's Role

The performance of 2,4-Diaminophenoxyethanol sulfate is directly linked to its purity. As a trusted hair dye intermediate supplier, we ensure our product maintains a high purity level of ≥98.0% (HPLC). Low ash content and minimal iron contamination are also critical. Impurities can interfere with the delicate oxidative coupling reactions, leading to inconsistent color results, dull shades, or even undesired color shifts. Therefore, sourcing from a reputable 2,4-diaminophenoxyethanol sulfate manufacturer in China that adheres to stringent quality control protocols is paramount.

Procurement and Market Insights

When considering procurement, understanding the market dynamics and the competitive 2,4-diaminophenoxyethanol sulfate price is important. Given its role in a widely consumed product category like hair color, consistent availability is key. We, as a leading supplier, aim to provide not only high-quality ingredients but also reliable supply chains and responsive customer service.
