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.
Claims16
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) optionally, 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, diethylene glycol mono(nonylphenyl)ether, hydroxy-triethoxydodecane and hydroxytri-ethoxytridecane;
- (b) from about 1% to about 25% by weight of said candle of a system-compatible functional composition selected from the group consisting of (A) a perfume composition;(B) an insect repellent composition and (C) an air freshener composition;
- and
- (c) optionally, one or more additives selected from the group consisting of an antioxidant, a stabilizer, a colorant and a flame retardant.
