Abstract: The present application relates to fragrance compositions comprising perfume raw materials that resist fragrance habituation, and methods for making and using the fragrance compositions.

Abstract: A process for flushing a dispenser and a process for combining a first composition and a second composition to form a mixture and dispensing said mixture through an exit orifice are provided; assemblies for flushing are also provided.

Abstract: A dispenser comprising a first reservoir in liquid communication with a first pump; a second reservoir in liquid communication with a second pump; exit orifice; and an actuator; wherein the first and second pumps are in liquid communication with the exit orifice; wherein the second pump is in liquid communication with the exit orifice; wherein said first and second pumps are in communication with the actuator; wherein the first reservoir comprises a first composition, comprising a volatile solvent and a first fragrance; wherein the second reservoir comprises a second composition, comprising a carrier and a plurality of microcapsules; wherein the exit orifice dispenses a first dose of the first composition and a second dose of the second composition; wherein the microcapsules have a volume weighted fracture strength from about 0.1 Mpa to about 25 Mpa, and a median volume-weighted particle size from about 2 microns to about 80 microns.

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.

Abstract: A method of providing a longer lasting fragrance and a kit for delivering a longer lasting fragrance by dispensing microcapsules and a volatile solvent is provided.

Abstract: An assembly for flushing a dispenser that internally mixes a first composition and a second composition; dispensers including said assemblies are also provided.

Abstract: In order to prevent the buildup of residual damaged microcapsules within a dispenser, the dispensers described herein are customized to allow for a flushing of the components of the mixture in order to remove any residual microcapsules that have come into contact with the volatile solvent.
