Dipropylene Glycol Propyl Ether (DPnP) Supplier in Malaysia
- Also known as
- Dipropylene Glycol N-Propyl Ether
- Dipropylene Glycol Monopropyl Ether
- DPnP
- 2-(2-Propoxypropoxy)propanol
Dipropylene glycol propyl ether supplier in Malaysia for cleaner, coating and ink formulators. Specification sheets write it as dipropylene glycol n-propyl ether or dipropylene glycol monopropyl ether, and the trade shorthand is DPnP. It is a clear liquid with a mild ether odour and good water solubility.
Its value sits in where it lands on the evaporation scale. Slower than the methyl ether of the same glycol and faster than the butyl ether, it stays in a drying film long enough to act as a coalescent while remaining water soluble enough to couple an aqueous concentrate.
That combination puts it into hard-surface cleaners and degreasers, waterborne architectural and industrial coatings, printing inks, wood finishes and agricultural concentrates. Supply is a single liquid, differentiated by purity, water content and colour rather than by separate product types.
Dipropylene glycol itself, and the methyl, dimethyl and butyl ethers of it, are separate products quoted under their own names. State the identity from your specification, the duty, the quantity and the delivery point when you enquire.

Dipropylene Glycol Propyl Ether grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical and industrial grade dipropylene glycol propyl ether | clear, colourless liquid | — | Coupling solvent in industrial and institutional cleaners, hard-surface degreasers and household concentrates, and general slow-release solvent duty in inks and wood coatings. | Drum, IBC or bulk options are set against the quotation. |
| Purity and colour controlled grade | clear, colourless liquid | — | Waterborne architectural and industrial coatings, tint bases and clear systems where colour, water content and residual impurities are held to the buyer's purchasing specification. | Sealed drum or IBC formats are set against the quotation. |

Dipropylene Glycol Propyl Ether applications
Safety and handling
Store in a closed container in a cool, ventilated area, clear of heat, ignition sources and strong oxidising agents. Because it is a slow-evaporating solvent, spills persist and should be contained rather than left to dry. Handle it in line with the safety information supplied for the quoted material. Supply is subject to applicable requirements.
Common questions about dipropylene glycol propyl ether
What other names and spellings cover dipropylene glycol propyl ether?
Specification sheets use dipropylene glycol n-propyl ether and dipropylene glycol monopropyl ether, formulators shorten it to DPnP, and the systematic form is 2-(2-propoxypropoxy)propanol. All four describe one molecule, so send the wording your own document uses and the identity can be matched.
Is dipropylene glycol propyl ether the same as dipropylene glycol?
No. Dipropylene glycol is the parent glycol and a different product with its own page, while this material carries a propyl group on one of the hydroxyls, which is what gives it solvency for oily soils. Order the parent glycol by name if the formulation calls for it.
How does it compare with the methyl and butyl ethers of dipropylene glycol?
All three are separate products. This propyl ether evaporates more slowly than the methyl ether and faster than the butyl ether, and it keeps better water solubility than the butyl version, which is why it is picked when a coupling solvent has to stay in a dilute aqueous concentrate.
Which CAS number applies to DPnP?
Glycol ethers in this family are supplied as isomer mixtures and the CAS entry cited varies between supplier documents, so no figure is printed here. Quote the CAS number shown on your specification with the enquiry and the identity will be confirmed against the documentation for the material offered.
Which grade suits a cleaner or a waterborne coating?
The technical and industrial grade covers cleaner concentrates, degreasers, inks and general formulation work. The purity and colour controlled grade is chosen for waterborne coatings, tint bases and clear systems where colour or water content is written into the purchase specification.
Why is a slow-evaporating glycol ether used in a waterborne coating?
A latex film needs the binder particles to soften and fuse before the water has gone. A slow solvent stays in the film long enough to do that, then leaves, so coalescents are chosen for late release rather than for speed.
What should be included in a dipropylene glycol propyl ether enquiry?
Include the identity as written on your specification, the application, the quantity per delivery and per year if known, the delivery location and any documents required. Anything you need held to a limit should be stated as a number so the offer can be checked against it.
