Abstract
A process for flushing a dispenser that dispenses liquids, especially perfumes, containing microcapsules. The dispenser has a first reservoir for a first composition containing microcapsules and a second reservoir for a second composition containing a volatile solvent. The dispenser also has a swirl chamber and a premix chamber. The process simultaneously pumps the first and second compositions into the premix chamber and then into the swirl chamber. The pumping of the first composition is halted while the pumping of the second composition continues, and this provides an extra volume of the volatile solvent, which flushes the dispenser to prevent clogging by the microcapsules.
