摘要:
Embodiments of the invention provide a fragrance distribution device comprising an electrical resistor, a plug or other power source, and a fragrance in a polymer or thermoplastic carrier. The polymer or thermoplastic carrier may include, for example, metal inclusions, which may be powdered metal. These metal inclusions are believed to enhance heat distribution throughout the carrier, thus allowing a more uniform and reliable release of fragrance.

摘要:
Methods and compositions of increasing volatile organic compounds in a container are disclosed. In particular, the invention discloses methods and composition for increasing the concentration of volatile organic compounds in the headspace of a container for a candle, shampoo bottle, or other product whose suitability for purchase is at least partially evaluated based on smell. Methods or compositions of the invention include the novel use of fragranced ethyl vinyl acetate in a variety of forms. The invention also includes a novel container for distribution of both a passive air freshener and a liquid spray air freshener.
