Dipropylene Glycol (DPG), CAS 25265-71-8, is a co-product generated during the manufacture of propylene glycol through the high-temperature, high-pressure hydrolysis of propylene oxide with excess water. Industrial grade DPG is a distilled material containing more than 99% dipropylene glycol, presented as a colorless, essentially odorless, water-soluble liquid with moderate viscosity and hygroscopic properties. It exists as a mixture of several structural isomers.
As a functional solvent and chemical intermediate, DPG serves commercial procurement teams across multiple industrial sectors. Its low vapor pressure and low toxicity profile support its use in formulations where worker exposure and emission control are operational priorities. TICHEM supplies industrial grade DPG backed by 13 years of functional solvent distribution experience, with parent company Titan Technology listed on the Science and Technology Innovation Board (stock code 688133).

The specifications above reflect typical physical and chemical properties of industrial grade DPG. The boiling point of 227°C and flash point of 124°C place DPG in the combustible liquid category, requiring standard storage and handling procedures. Its viscosity of 75 cP at 25°C contributes to its role as a thickener and viscosity modifier in various formulations.
DPG functions as a reactant in unsaturated polyester resin production, contributing to the flexibility and hydrolytic stability of the finished resin. In dicyclopentadienyl unsaturated polyester resin systems, it is incorporated to enhance flexibility characteristics. Formulators in the composites and fiberglass-reinforced plastics sectors use DPG to adjust resin properties for specific end-use requirements.
DPG serves as a starting agent in polyurethane polyol synthesis and can also function as a polyol component in polyurethane rigid foam formulations. Polyurethane manufacturers utilize DPG to influence foam density, cell structure, and mechanical properties in insulation and construction applications.
DPG undergoes esterification with benzoic acid to produce dipropylene glycol dibenzoate, a compound used as a plasticizer in polymer processing. This application supports business operations in the polymer additives and compounding industries.
Through esterification with acrylic acid, DPG is converted into dipropylene glycol diacrylate (DPGDA), a raw material used in radiation-curing resin formulations. This application serves the UV/EB curing coatings and inks sector.
DPG's solubility profile supports its use in selected oils and aqueous systems. Its low volatility and low toxicity characteristics make it suitable for brake fluid formulations, cutting oils, spinning machine lubricants, printing inks, coatings, and industrial soaps. It also serves as a solvent in pesticide and insecticide formulations for agricultural chemical operations.
