  • Publication number: 20070275866
    Abstract: The present invention relates to perfume delivery systems, products comprising such systems and the use of same. Unfortunately current perfume delivery systems do not always provide the most preferred or ideal sensory experience. Thus there is a need for one or more perfume delivery systems that obviate the short comings of the current perfume delivery technologies. The systems of the present invention meet the aforementioned need as they employ symbiotic combinations.
