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.

What is claimed is: 1. A substantially hydrocarbon-free, substantially stearic acid-free, transparent, syneresis-free candle comprising at least one substantially upright wick partially imbedded in a composition consisting essentially of: (a) from about 75% by weight of said candle to about 99% by

What is claimed is: 1. A substantially hydrocarbon-free, substantially stearic acid-free, transparent, syneresis-free candle comprising at least one substantially upright wick partially imbedded in a composition consisting essentially of: (a) from about 75% by weight of said candle to about 99% by weight of said candle of a gellant-solvent-surfactant/additional solvent system consisting essentially of: (i) from about 20% to about 70% by weight of said candle of a gellant selected from the group consisting of (A) at least one ester-terminated polyamide; and (B) at least one tertiary amide-terminated polyamide; (ii) from about 15% up to about 60% by weight of said candle of a solvent selected from the group consisting of (A) at least one methyl ester of a vegetable-derived C12-C18 carboxylic acid and (B) at least one glyceryl ester of a vegetable-derived C10 carboxylic acid and, optionally admixed therewith, an additional solvent selected from the group consisting of dipropylene glycol and isopropyl myristate; and (iii) from about 3% to about 20% by weight of said candle of at least one surfactant having a hydrophile/lipophile balance in the range of from about 3 up to about 7, selected from the group consisting of, di(hydroxyethoxy)coconut amine, (hydroxy-triethoxy)coconut amine, (hydroxy-diethoxy)coconut amine, N-(hydroxyethoxy)-N-(hydroxydiethoxy) coconut amine, hydroxy-triethoxydodecane and hydroxytri-ethoxytridecane; (b) from about 1% to about 25% by weight of said candle of a system-compatible functional perfume composition; and (c) optionally, one or more additives selected from the group consisting of an antioxidant, a stabilizer, a colorant and a flame retardant. 2. The candle of claim 1 wherein the gellant is an ester-terminated polyamide having a weight-average molecular weight of about 6000 and a softening point in the range of from 88° C. to 94° C. prepared by reacting "x" equivalents of C36 dicarboxylic acid, "y" equivalents of ethylenediamine and "z" equivalents of an alcohol selected from the group consisting of cetyl alcohol and stearyl alcohol wherein 0. 9≦{x/(y+z)}≦1.1 and 0.1≦{z/(y+z) }≦0.7 and the solvent is a mixture of soy fatty acid methyl ester and isopropyl myristate, the weight ratio of soy fatty acid methyl ester:isopropyl myristate being from about 2:1 to about 20:1. 3. The candle of claim 1 wherein the system-compatible functional perfume composition has a Clog10P of between 2.5 and 8.0, according to the inequality:2.5≦Clog10 P≦8.0, wherein the term Clog10P represents the calculated logarithm to the base 10 of the n-octanol/water partition coefficient of the said component. 4. The candle of claim 1 substantially in the shape of an upright cylinder or conical frustum having substantially planar horizontally-disposed upper and lower surfaces each of which surface is substantially perpendicular to a common substantially vertically-disposed surface juxtaposed to each of said horizontally-disposed surfaces, said substantially vertically-disposed surface being coated with a fatty acid dimer-based polyamide resin. 5. A process for preparing the candle of claim 1 comprising the steps of: (a) mixing the gellant, solvent and surfactant at a temperature in the range of from about 95° C. up to about 110° C. for a time period sufficient to cause the admixture to be a stable single liquid phase; (b) cooling the resulting gellant-solvent-surfactant system mixture to a temperature in the range of from about 75° C. up to about 85° C.; (c) admixing a system-compatible functional perfume composition with the resulting gellant-solvent-surfactant system mixture thereby forming a functional perfume composition-gellant-solvent-surfactant system mixture; (d) optionally adding one or more additives to the resulting functional perfume composition-gellant-solvent-surfactant system mixture; (e) placing the resulting mixture into a mold while the resulting mixture is in the liquid phase; (f) causing at least 1 candle wick to be embedded in the resulting liquid phase mixture; and (g) cooling the resulting mixture to ambient temperature whereby a candle is formed having two oppositely-situated substantially parallel horizontally-disposed planar surfaces, each of which is substantially perpendicular and juxtaposed to a substantially vertically-disposed surface. 6. A process for preparing the candle of claim 1 comprising the steps of: (a) mixing the gellant, solvent and isopropyl myristate at a temperature of about 100° C. for a time period sufficient to cause the admixture to be a stable single liquid phase; (b) cooling the resulting gellant-solvent-isopropyl myristate system mixture to a temperature of about 90° C.; (c) admixing a system-compatible functional perfume composition with the gellant-solvent-isopropyl myristate mixture thereby forming a functional perfume composition-gellant-solvent-isopropyl myristate system mixture; (d) optionally adding one or more additives to the resulting mixture; (e) placing the resulting mixture in a molding while the resulting mixture is in the liquid phase; (f) causing at least 1 candle wick to be embedded in the resulting liquid phase mixture; and (g) cooling the resulting mixture to ambient temperature whereby a candle is formed having two oppositely situated substantially parallel horizontally-disposed planar surfaces, each of which is substantially perpendicular and juxtaposed to a substantially vertically-disposed surface.
