Description
Resorcinol (CAS 108-46-3, EC 203-585-2, formula C6H6O2) is an aromatic diol also known as resorcin, Resorcine, and Resorzin. It carries no assigned E-code and is classified as a pharmaceutical intermediate with relevance across multiple industrial sectors.
In hair dye formulations, resorcinol acts as a coupling agent that bonds with oxidative colorants to produce stable, long-lasting color. In rubber manufacturing, it functions as an adhesion promoter between textile cords and rubber compounds by forming resin networks at the interface. It also serves as an antimicrobial and preservative active in topical pharmaceutical preparations.
Resorcinol is supplied as a white crystalline solid meeting Ph.Eur. and USP/FCC grade specifications, supporting both pharmaceutical and cosmetic applications under REACH compliance. Standard packaging includes fiber drums and multi-layer bags. Buyers should confirm SDS documentation and regulatory status under EU cosmetics regulation before formulation use.
