Description

N,N-bis(2-hydroxyethyl)-p-phenylenediamine sulfate (CAS 54381-16-7 ) is an oxidative hair dye intermediate used to develop color in permanent and semi-permanent hair coloring systems. Supplied as a stable sulfate salt, it functions as a primary coupler or developer component that reacts with oxidizing agents to produce targeted color shades for various applications. In professional and retail hair color formulations, it is combined with hydrogen peroxide and coupling agents to achieve brown, auburn, and neutral tone results across different hair types. Textile dyeing operations use it as a dye intermediate for producing azo and oxidation dyes on natural and synthetic fiber substrates. It ensures consistent color depth and durability. In leather finishing, it contributes to surface coloration processes where controlled oxidative dyeing is required. Paper manufacturers incorporate it in specialty coloring applications for uniform pigmentation. The product is supplied as a crystalline powder or fine solid. It is available in cosmetic-grade specifications aligned with requirements for use in regulated personal care formulations. This includes compliance with EU Cosmetics Regulation annex listings. Technical-grade material is also available for textile and industrial dyeing applications requiring high purity and stability.
