Description
Hydroquinone bis(2-hydroxyethyl) ether, also known as hydroquinone diethylol ether (CAS 104-38-1, EC 203-197-3), is a diol compound derived from hydroquinone and ethylene oxide. It carries no assigned E-code and is commercially identified by its molecular formula C10H14O4.
In personal care formulations, it functions as a solvent and carrier that improves the solubility and delivery of active ingredients such as hair dye intermediates and fragrance components. In printing and packaging applications, it serves as a reactive diluent or co-initiator alongside photoinitiators, contributing to UV-cure system performance through its hydroxyl functionality.
This material is supplied as a crystalline powder or flakes and falls under REACH registration requirements for European market supply. Procurement teams should confirm supplier compliance documentation, including Safety Data Sheets aligned with EU GHS standards. It is classified under HS code 29094990 for customs and import purposes.
