A liquified gas is usually used as a propellant. ... As it is released, the gas evaporates from the liquid in the container causing constant performance and pressure within the aerosol. When the liquid mixture is released from the aerosol, the liquid propellant becomes a gas and helps break up the product into a fine mist.
