Diethylene glycol monophenyl ether

Diethylene glycol monophenyl ether (CAS 104-68-7) is a glycol ether solvent also known by the abbreviations PhDG and phenyldigol. It carries no assigned E-code and is registered under EC number 203-227-5. It is commercially available under reference codes including NSC 406593.

In architectural and industrial coatings, PhDG functions as a coalescing solvent, lowering the minimum film-formation temperature of latex systems to produce uniform, defect-free films. In personal care formulations, it acts as a coupling agent and rheology modifier, improving the compatibility of oil and water phases while adjusting viscosity and flow behaviour.

PhDG is supplied as a technical-grade clear liquid and falls under REACH registration requirements for EU market supply. It is classified under HS code 2909.44.0150 for customs purposes. Packaging formats typically include drums and intermediate bulk containers; buyers should confirm grade specifications and SDS documentation with the supplier prior to ordering.
