13. A method for packaging a dispensable substance, the method comprising the steps of:
placing a first product component into a container;
adding a second product component into said container at an initial pressure of less than 1.31 atm, said container comprising a valve dispensing port;
sealing said container;
increasing pressure in said container through a phase change of the second product component to a final pressure in said container, said final pressure being at least 0.26 atm greater than said initial pressure;
forming, through the phase change of the second product component, gas bubbles of the second product component in the first product component; and
forming a gas phase propellant of the second product component in said container.
