    • 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.
    • 本发明提供了一种生产个人护理产品的方法,包括将香料,推进剂和多孔载体颗粒混合,以产生基本上不含预包封的香料颗粒的组合物,并将该组合物包含在加压容器中。 还提供了一种个人护理产品,其包含加压容器和其中所含的组合物,其包含香料,推进剂和多孔载体颗粒,其中所述组合物基本上是游离的预包封香料颗粒。 当组合物从容器中释放时,推进剂迅速蒸发以产生将香料并入载体的孔中的基质,以产生持续释放香料递送系统。
