Dipropylene Glycol (DPG)
CAS 25265-71-8
Dipropylene Glycol (DPG) is a water-soluble glycol mixture used as a solvent, coupling agent, humectant, and chemical intermediate in personal care, fragrance, coatings, urethane, resin, and industrial applications. Dow public product pages describe regular DPG as a clear hygroscopic liquid with purity greater than 99%, while low-odor fragrance/personal-care grades are referenced around 99.5% purity. Final grade-specific sales values should still be confirmed through supplier TDS and COA.
- Functions as a solvent, coupling agent, and chemical intermediate across multiple industries
- Water miscibility supports formulation flexibility in industrial and personal care applications
- Can act as a viscosity modifier and provide added flexibility in resin systems
- Available in regular or high-purity low-odor supply references depending on the target application

Packaging & storage
Packaging options
- Regular commercial packaging to be confirmed during inquiry
- Drum, tote, or bulk supply options should be aligned with the requested grade and region
Storage
General industry practice is to store DPG in carbon steel vessels, with lined steel or stainless steel recommended where discoloration control is important. Keep containers tightly closed in a cool, dry, well-managed storage environment and confirm final handling details against the supplier SDS/TDS.
Shelf life: Public TDS references indicate stability for at least 12 months from the date of manufacture when stored under recommended conditions.
FAQ
Frequently asked questions
What is DPG commonly used for?
DPG is commonly used as a solvent, coupling agent, humectant, and intermediate in personal care, fragrances, urethane systems, coatings, plasticizers, and resin applications.
Is DPG water soluble?
Yes. Public manufacturer references describe DPG as completely soluble in water and useful where water miscibility is important.
What should be confirmed before ordering?
The final grade, odor profile, color, packaging, regional availability, and release specification values should be confirmed against supplier TDS and COA.
