Definitions

  • the present invention relates generally to a composition for delivering aroma. More particularly, the present invention relates to a composition for aroma delivery that is generated by an exothermic reaction.
  • Aromatic volatile components have been widely used in variety of products, including pharmaceutical products.
  • Certain types of aromatic volatile components e.g., menthol, eucalyptus oil, camphor, thymol
  • menthol eucalyptus oil
  • camphor eucalyptus oil
  • thymol eucalyptus oil
  • These pharmaceutical products are commonly used by inhaling aroma vapours along with water vapours to relieve blocked nose, cough, and other cold or allergy symptoms.
  • the vapours are generated by using hot water or steam.
  • aromatic volatile components have become increasingly popular. Consumers with mental stress often prefer to be in perfumed environments as a way to decrease stress. Due to their ability to induce relaxation and relief of mental stress, certain aromatic volatile components have become popular for treatment and therapy of such stress. These aromatic volatile components (e.g., cineol, jasmine, lavender oil) are known for providing fragranced environments in aroma therapy, as aromatic fragrance components.
  • aromatic volatile components e.g., cineol, jasmine, lavender oil
  • aroma therapy refers to a therapy which is for mental treatment, getting away from or releasing stress and, inducing relaxation, especially to ease mental stress.
  • a conventional aroma therapy is by an inhalation of aroma vapours.
  • Aroma is generated from the aromatic fragrance components by using hot water in combination with aromatic actives, or by heating a vessel, for example a pot or a plate, in which aromatic fragrance ingredients and water are placed. Consumers, however, tend to become frustrated with such methods of use, i.e., heating water for aroma vapours andfor steam inhalation, and with cleaning messy vessels due to oily or waxy bases used for aroma generation after the inhalation of aroma vapours.
  • exothermic reactions have been previously used for the purpose of generating heat or increasing temperature.
  • a variety of products using exothermic reactions are known, for example, in food products (e.g., self-heating meal modules, see Taub et al. U.S. Patent 5,517,981), pharmaceutical products (e.g., body warmers, see Sahara, U.S. Patent 5,220,909), or smoking articles (e.g., cigarette, see Potter et al. U.S. Patent 4,955,399).
  • the present invention is directed to a composition for aroma delivery comprising: (a) an aromatic ingredient; (b) an exothermic ingredient; and (c) a pH adjusting agent; wherein the aroma is delivered when water is added to the composition.

Without being bound by theory, it is believed that such temperature range is suitable for volatilizing aromatic ingredients including an aromatic active compound, and an aromatic fragrance compound.
