1. A method of delivering a dose of a liquid composition from a microfluidic delivery refill, wherein the liquid composition comprises volatile components such that the liquid composition is defined by a flash point temperature and a boiling point temperature, and wherein the microfluidic delivery refill comprises a reservoir enclosing the liquid composition and a microfluidic delivery member comprising a heater in fluid communication with the reservoir, the method comprising:
deactivating the heater of the microfluidic delivery member, wherein, when the heater is deactivated, a temperature of the heater is less than the flash point temperature of the liquid composition; receiving an electrical signal with the heater of the microfluidic delivery member;activating the heater of the microfluidic delivery member in response to the electrical signal, wherein, when the heater is activated, the temperature of the heater is greater than the boiling point temperature of the liquid composition; and
vaporizing at least a portion of the volatile components of the liquid composition when the heater is activated, whereby the dose of the liquid composition is delivered from the microfluidic delivery member.
