  • Patent number: 7160337
    Abstract: Described is a transparent syneresis-free candle which is substantially hydrocarbon-free, e.g., mineral oil-free and paraffin wax-free; substantially stearic acid-free and consistently-maintained functional compositional integrity on use thereof. The candle composition contains a gellant that is an ester-terminated polyamide or a tertiary amide-terminated polyamide, a non-hydrocarbon solvent which is a vegetable-derived fatty acid ester, and a system-compatible functional fragrance composition, an insect repellent composition and/or an air freshener composition. The candle can be a pillar candle which is free-standing or a container candle.

  • Patent number: 6790436
    Abstract: Described is a substantially rigid aqueous clear gel matrix air freshener article having included therein one or more gel matrix icons, the dimensions of which, on use of the article, decrease in proportion to the dimensions of the body of the air freshener article in which the icons are suspended and imbedded. The article contains water; gel matrix material which can be a hydrolyzed protein gel material such as gelatin or a polysaccharide gel material such as gellan gum; a system-compatible air freshener fragrance composition contained in one or more of the icons and/or contained in the gel matrix air freshener body; and a surfactant contained in the body.

  • Publication number: 20040156742
    Abstract: Described is an ester mixture of 1-cyclohexylethan-1-yl butyrate and 1-cyclohexylethan-1-yl acetate wherein the weight ratio of 1-cyclohexylethan-1-yl butyrate:1-cyclohexylethan-1-yl acetate is from about 20:80 up to about 80:20. The mixture is synergistically effective for its ability to counteract a malodour (1) emanating from a malodourous solid or liquid source into a 3-space proximate the solid or liquid source or (2) present in a malodourous air 3-space.

  • Publication number: 20030213163
    Abstract: Candles are disclosed that include a wick, a first phase and a second phase. In one embodiment, the first phase is substantially clear and has a first melting point, the second phase is visually distinct from the first phase and has a second melting point, and the second melting point is greater than or about equal to the first melting point. In another embodiment, the first phase contains a first concentration of gellant in first solvent, the second phase contains a second concentration of gellant in second solvent, and the first and second concentrations are non-identical. In another embodiment, the first and second phases each contain gellant, however the second phase contains components not present in the first phase.

  • Patent number: 6242509
    Abstract: An ester-terminated dimer acid-based polyamide may be blended with a solvent to form a gel. The solvent may be flammable, and a wick may be added to the resulting gel so as to form a candle. Depending on the composition, the candle may be formed into a free standing pillar, or may be better suited to being placed in a container. The solvent may be mineral oil. A solid coating may be placed around the candle, for advantages including to enhance the clarity and/or mechanical stability of the gelled body, and to eliminate the tendency of a gel to have an oily feel and to accept noticeable fingerprints. The ester-terminated dimer acid-based polyamide may also be combined with an active ingredient, such as a fragrance, colorant, insect-repellant, insecticide, bioactive ingredient or the like, to afford a delivery vehicle for the active ingredient.
