Dipropylene Glycol Monomethyl Ether

Dipropylene glycol monomethyl ether (DPM) is a clear, colourless liquid with a faint ether-like odour. It is soluble in water and has moderate volatility.

Dipropylene glycol monomethyl is produced by reacting propylene oxide with methanol using a catalyst. It is a mixture of four structural isomers: 1-(2-methoxypropoxy)propanol-2, 1-(2-methoxy-1-methylethoxy)propanol-1, 2-(2-methoxypropoxy)propanol-1 and 2-(2-methoxy-1-methylethoxy)propanol-1.

Synonyms: Dipropylene glycol monomethyl ether, Dipropylene glycol methyl ether, Methoxypropoxypropanol, (2-methoxymethylethoxy) propanol, 2-(2-methoxypropoxy)propanol, DPM glycol ether, DPGME, 1-(2-methoxy-1-methylethoxy)-2-propanol, 1-(2-methoxyisopropoxy)-2-propanol

Applications of Dipropylene Glycol Monomethyl Ether

Dipropylene glycol monomethyl ether is primarily used as a solvent in paints, varnishes, printing inks and strippers and in coatings for automotive and architectural applications, wood and coil coatings and metal finishing. It is also used as a coalescent agent in water-based paints and inks where it serves to promote polymer fusion during the drying process, as a chemical building block for the production of dipropylene glycol monomethyl ether acetate, and as a chemical additive in the oil and drilling industry.

It is found in a wide range of household and industrial cleaners including all-purpose cleaners, glass and other surface cleaners, paint brush cleaners, disinfectants and carpet cleaners. It is also used as a coupling agent in fabric dyes; as a solvent, coupler, emollient and stabilizer in cosmetic products; and as a stabilizer in pesticides and herbicides.

Storage and Handling

Dipropylene glycol monomethyl should be stored in a cool, well-ventilated place away from sources of ignition and static discharge. It must be isolated from incompatible materials such as strong oxidizing and reducing agents, alkali metals and nitrides.

Dipropylene glycol monomethyl is a mild irritant to the skin and eyes. Excessive inhalation may cause irritation to the respiratory tract and drowsiness. Such risks should be managed by engineering controls, adequate ventilation and by the use of approved personal protective equipment including gloves, clothing and safety goggles and the use of respirators where appropriate to the task being carried out. All handling should be carried out in a chemical fume hood.
