Boiling point:: −24.8 °C(lit.)

Density: 1.617

vapor density: 1.62 (vs air)

vapor pressure: >760 mm Hg ( 25 °C)

refractive index: 1.2984

Flash point:: -41°C

solubility: Soluble in acetone, chloroform, ethanol (95%), ether, and 1 in 3 parts of water. Dimethyl ether is generally miscible with water, nonpolar materials, and some semipolar materials. For pharmaceutical aerosols, ethanol (95%) is the most useful cosolvent. Glycols, oils, and other similar materials exhibit varying degrees of miscibility with dimethyl ether.

Use

Dimethyl ether may be used as an aerosol propellant for topical aerosol formulations in combination with hydrocarbons and other propellants. Generally, it cannot be used alone as a propellant owing to its high vapor pressure. Dimethyl ether is a good solvent and has the unique property of high water solubility, compared to other propellants. It has frequently been used with aqueous aerosols. A coarse, wet, spray is formed when dimethyl ether is used as a propellant. Dimethyl ether is also used as a propellant in cosmetics such as hair sprays,and in other aerosol products such as air fresheners and fly sprays. Dimethyl ether is additionally used as a refrigerant.
