  • Publication number: 20100021855
    Abstract: A non-sooting containerized candle is disclosed. The containerized candle includes a container having a top opening and a plurality of holes in an upper side wall portion of the container, a wick, a sustainer for securing the wick to the base of the container, and wax or other fuel material surrounding a major portion of the wick. The plurality of holes can be present in varying patterns in the upper side wall portion of the container to control air flow into and out of the container to provide complete combustion of the candle and prevent emission of carbon particulates. The pattern of holes control or adjust air flow around the burning wick from a turbulent air flow to a laminar air flow.

  • Patent number: 7410513
    Abstract: A wax composition comprising a high molecular weight aliphatic alcohol, a low molecular weight ethylene vinyl acetate copolymer, at least one odorant, and a wax. The odorant is substantially retained in the wax composition when the wax composition is exposed to temperatures below a melting point of the wax composition. Furthermore, the odorant is emitted from the wax composition when the wax composition is exposed to temperatures at or above the melting point of the wax composition.

  • Patent number: 7001875
    Abstract: Dual colorants are disclosed. The colorants of the present invention include at least one compound, which exhibits a first color outside an aqueous environment and a second color after placement into an aqueous environment. In some cases, the colorant includes an oil-soluble dye capable of exhibiting the first color and a water-soluble dye capable of exhibiting the second color. In certain embodiments, such colorants may be used in toilets. In these embodiments, the first color corresponds to a color associated with a fragrance, such as red for rose, while the second color corresponds to a color associated with cleanliness in a toilet, such as blue or green.

  • Patent number: 6939841
    Abstract: Effervescent compositions are disclosed. The effervescent composition may include at least one compound capable of effervescence in the presence of a liquid, such as water. The effervescent composition may also include a non-hygroscopic solvent. The presence of the non-hygroscopic solvent may assist the effervescent composition in substantially avoiding effervescence until the composition contacts a liquid. Optionally, the ratio of the at least one compound capable of effervescence to the non-hygroscopic solvent is not less than 9:1.
