Abstract
Disclosed are candles having a wick, a wax composition, and a gel composition, wherein the wax composition encloses the wick, and the wick is separated from the gel composition. The candle while being burned exhibits one or more desirable properties, such as reduced levels of soot or reduced emissions of volatile organic compounds (VOCs).
Claims23
A candle comprising a wick, a wax composition, and a gel composition, wherein the wax composition encloses the wick and in communication with the gel composition, and the wick is separated from the gel composition.
The candle of any one of the preceding claims, wherein the ratio between the wax composition and the gel composition is in the range of 1:99 to 99:1.
The candle of any one of the preceding claims, wherein the candle has a core and an outer layer, the core is formed of the wax composition, the outer layer is formed of the gel composition, and the space between the outer layer and the wick is 1 cm or greater.
The candle of any one of the preceding claims, wherein the wax composition has a melting point of 40° C. to 95° C., and the gel composition has a melting point of 55° C. to 125° C.
The candle of any one of the preceding claims, wherein the wick is formed of cotton, linen, cellulose, plastics or ceramic material, paper, hemp, wood, metal, or a combination thereof.
The candle of any one of the preceding claims, further comprising an additive selected from the group consisting of a flame retardant, an antioxidant, an insect repellent, a colorant, and a combination thereof.
The candle of any one of the preceding claims, wherein the wax composition is a soy wax, a paraffin wax, a palm wax, a beeswax, a hydrogenated natural oil, or a combination thereof.
The candle of any one of the preceding claims, wherein the candle has two or more wicks.
The candle of any one of the preceding claims, wherein the wick contains a catalyst.
The candle of any one of the preceding claims, wherein the candle is a free-standing candle.
The candle of any one of the preceding claims, wherein the candle has a soot index of 0.3 to 10.
The candle of any one of the preceding claims, whereby when the candle is burned it produces reduces emissions of volatile organic compounds (VOCs), preferably the reduction is at least 20%, at least 30%, or at least 40%, as compared to a control candle that does not include the gel composition.
The candle of any one of the preceding claims, wherein the gel composition is essentially free of a wax or any other fuel components.
A method comprising the steps of:
- a) admixing a gelling agent, a fragrance and optionally a solvent to form a gel composition;
- b) forming a wax composition selected from the group consisting of a soy wax, a paraffin wax, a palm wax, a beeswax, a hydrogenated natural oil;
- and
- c) incorporating the gel composition adjacent to an outer surface of the wax composition;
- wherein the candle during use has the property of producing reduced levels of soot as compared to a control candle that does not include the gel composition, and/or producing reduced emissions of volatile organic compounds (VOCs) as compared to a control candle that does not include the gel composition.
