    摘要: The invention provides a method of producing a personal care product comprising combining a fragrance, a propellant and porous carrier particles, to produce a composition substantially free of pre-encapsulated fragrance particles, and containing the composition in a pressurized container. Also provided is a personal care product comprising a pressurized container and a composition contained therein, which includes a fragrance, a propellant and porous carrier particles, wherein the composition is substantially free pre-encapsulated fragrance particles. When the composition is released from the container, the propellant evaporates rapidly to produce a matrix, which incorporates the fragrance into the pores of the carrier, to produce a sustained-release fragrance delivery system.
