    摘要: The present invention pertains to an aroma component assessment method and a method for preparing a fragrance composition using said assessment method. The present invention provides a fragrance composition appropriate for a product in consideration of usage conditions of the product. For that purpose, the present invention involves: making measurements of the rate of concentration increase (i.e., detection quantity a of aroma component after lapse of a predetermined time after start of measurement/detection quantity b of aroma component immediately after the start of detection) of aroma released within a prescribed time range for each of two or more types of aroma components contained in a product within a consumption environment of said product or within a model environment thereof; and assessing the impact of the aroma components contained in the product on fragrance impressions of the product, using the magnitude relationship in the aroma concentration increase rate of the two types or more aroma components, as an index correlated with the magnitude relationship of the impacts on fragrance impressions of the product, so as to make objective and appropriate assessments of the impacts of the aroma components contained in the product on fragrance impression.

    摘要: Fragrance delivery device with first flexible impermeable barrier layer and second flexible impermeable barrier layer coupled to the first flexible impermeable barrier layer to define a first chamber. A reservoir substance having a volatile medium is disposed in the first chamber. The device further includes at least one vapor releasing microporous layer having a plurality of micropores therein. The vapor releasing microporous layer defines a second chamber. A frangible seal seals the first chamber from the second chamber in a delivery condition. Activation of the device compromises the frangible seal to fluidly couple the first chamber with the second chamber and to transfer the reservoir substance to the second chamber. The volatile medium of the reservoir substance is releasable from the fragrance delivery device via the plurality of micropores in the use condition.
