  • Patent number: 9457204
    Abstract: This invention provides an effervescent solid form that dissolves in cold water quickly enough to not disappoint consumers yet not so quickly that the visual interest generated during the effervescent reaction is lost. This performance is achieved by forming effervescent particles that are dense enough to retard dissolution and small enough to not take too long to dissolve. The aim of this invention is to provide a beverage in solid effervescent form that takes between about 30 and about 120 seconds to dissolve in warm water. The granules may carry functional additives such as flavors, vitamins, minerals, sweeteners, colors and drugs. The granules may also be compounded of materials intended to provide relief from skin or topical discomfort, as in the form of a wash or bath additive. The granules may also be formulated to provide cleaning agents, such as ceramic cleaners and denture cleaners.

  • Patent number: 8206686
    Abstract: This invention provides a tablet that effervesces and significantly warms the water that it is dissolved in. The effervescence acts to break up the tablet allowing an exothermic material to rapidly dissolve releasing its heat of solution. The invention is unique in that no organic acid is required to form a conventional effervescent couple.

  • Patent number: 8192724
    Abstract: A water soluble, non-abrasive, effervescent, pharmaceutically acceptable, oral care tablet for use in the oral cavity. The tablet includes a carbon dioxide source, a acid source and a tablet forming material admixed to form a chewable tablet having less than 0.2% water. The carbonate to acid ratio ranges from about 2.33:1 to about 3.33:1, the percent by weight of tablet forming material ranges from about 10% to about 70% of the total tablet weight, and the pH of the tablet when dissolved in water to form a 1.0% by weight aqueous solution ranges from about 5.0 to about 7.0. Also included is a flavor imparting flavor agent in an amount sufficient to mask taste sensations derived from the carbon dioxide source, acid source and binder to provide an abrasive-free texture to the tongue in the oral cavity. Other additives are contemplated.

  • Patent number: 8007842
    Abstract: A composition for providing aromatherapy, and in particular, symptomatic relief of nasal and sinus congestion is provided in unit dosage format. The composition includes a penetrating aromatic vapor whose release from a preparation of warm water is augmented by an effervescent component which reacts in the warm water to promote release of the aromatic fragrance, or sustained over time by tableting or gelatin encapsulation. As the fragrance is inhaled, symptomatic relief is obtained. The composition of matter may be rendered ingestible, so that the warm water containing the composition is consumed following inhalation. In preferred embodiments, the release of the penetrating aromatic fragrance persists over time.
