Chemical Name: Dipropylene Glycol
CAS Number: 25265-71-8
Synonyms: DPG, Dipropylene Glycol Mixture
Category: Glycol Solvent / Chemical Intermediate
Dipropylene glycol (DPG) is a low-volatility, high-boiling-point polyol solvent, formed by the dehydration condensation of propylene glycol, and typically exists as a mixture of isomers. This product possesses excellent solubility, good chemical stability, and low odor, and is widely used in fragrances, cosmetics, coatings, inks, resins, electronic chemicals, and industrial cleaning applications.
Compared to propylene glycol (PG), DPG exhibits better stability at high temperatures and is a commonly used high-performance solvent in fragrances and industrial formulations.
