A freshening composition and method of jetting a freshening composition from a microfluidic device are provided. The composition includes greater than 5 wt. % of solubilizing materials that are liquid at 20 C. Each of the solubilizing materials have a Hansen polarity parameter (p) of greater than 5 MPa0.5; a Hansen hydrogen-bonding parameter (h) of greater than 9 MPa0.5; and a vapor pressure of less than 267 Pa. The method includes heating the freshening composition with a thermal actuator and atomizing the heated composition from a nozzle in a direction that is from 0 degrees to 90 degrees from the direction of gravitational force.
