WitrynaDimethyl ether is an organic compound from the group of ethers. It is a colourless gas with a characteristic odour, moderately soluble in water. The product in aerosol is used as a propellant (factor for discharging content). It is used instead of the previously applied CFCs, as it has no harmful effect on the ozone layer.
