Air freshener taper candle product

in Candle

This invention provides an air freshener candle product which is a slender combustible body composed of ingredients which comprise candlewax, thermoplastic polymer, particulate polysaccharidic filler, and air freshener ingredient. The air freshener is released into the atmosphere under candle burning conditions. An invention taper-shaped candle is wickless, and can be produced by a continuous molding process.

This invention generally relates to the dispensing of an air freshener from a candle product. More specifically this invention relates to a wickless candle having a content of air freshener ingredient which is released under candle combustion conditions.

Candles have been known and used since early civilization. A typical candle is formed of a solid or semi-solid body of wax such as paraffin wax or beeswax, and it contains an axially embedded combustible fibrous wick.

When the wick of a candle is lit, the generated heat melts the solid wax, and the resulting liquid flows up the wick by capillary action and is combusted.

More recently candles have been developed that appeal to the olfactory as well as the visual sense. This type of candle usually incorporates a fragrance oil in the wax body. As the wax is melted in a lighted candle, there is a release of the fragrance oil from the liquified wax pool.

Conventional fragrance candles have drawbacks because of cost and other considerations. The incorporation of fragrance oil in candlewax is difficult to achieve in a quantity which ensures the release of a suitable level of fragrance into the atmosphere during candle burning. Further, the incorporated fragrance tends to migrate and volatilize from the wax body prematurely. The fragrance also softens the wax body, and there is an undesirable loss of rigidity in the candle structure.

There is continuing interest in the development of improved fragrance and other types of air freshener candle products.

Accordingly, it is an object of this invention to provide an air freshener candle product which releases air freshener into the atmosphere only under the combustion conditions of the burning candle.

It is another object of this invention to provide a taper-shaped wickless air freshener candle product.It is a further object of this invention to provide an air freshener candle product which can be produced by a continuous molding process.Other objects and advantages of the present invention shall become apparent from the accompanying description and examples.

The candlewax ingredient can be selected from commercially available wax media. The combustible body of a candle product typically is a thermoplastic blend of organic materials such as beeswax, paraffin wax, montan wax, carnauba wax, microcrystalline wax, fatty alcohols, fatty acids, fatty esters, and the like.

The polymer ingredient of an invention air freshener candle product preferably is selected from the class of thermoplastic resins which in general are adapted for fiber-formation by processes such as extrusion or compression molding. It is preferred that the polymer is composed of elements which do not convert into noxious vapors under candle combustion conditions, such as carbon, hydrogen and oxygen.

Formation of an invention air freshener candle product can be accomplished by the extrusion of a molten or particulate blend of the candle ingredients, or by compression molding of the blended ingredients.

The term "air-freshener" as employed herein is meant to include fragrances such as geraniol, insect repellants such as citronellal, and therapeutic agents such as menthol.

An air freshener ingredient of a present invention candle product can be any inherently volatile organic compound which is capable of being dispersed into the atmosphere when the candle product is burning.

Suitable volatile air freshener compounds include limonene, α-terpinene, α-pinene, camphene, undecanol, 4-isopropylcyclohexanol, geraniol, linalool, citronellol, farnesol, menthol, 3-trans-isocamphylcyclohexanol, benzyl alcohol, 2-phenylethyl alcohol, 3-phenylpropanol, 3-methyl-5-phenylpentanol, cinnamic alcohol, isoborneol, thymol, eugenol, isoeugenol, anise alcohol, methyl salicylate, and the like.

Other suitable air freshener compounds include aldehydes and ketones such as hexanal, decanal, 2-methyldecanal, trans-2-hexenal, acetoin, diacetyl, geranial, citronellal, methoxydihydro-citronellal, menthone, carvone, camphor, fenchone, ionone, irone, damascone, cedryl methyl ketone, muscone, civetone, 2,4-dimethyl-3-cyclohexene carboxaldehyde, 2-heptylcyclopentanone, cis-jasmone, dihydrojasmone, cyclopentadecanone, benzaldehyde, phenylacetaldehyde, dihydrocinnamaldehyde, cinnamaldehyde, α-amylcinnamaldehyde, acetophenone, benzylacetone, benzophenone, piperonal, and the like.

Other suitable air freshener compounds include crystalline fragrance materials with a high vapor pressure, such as vanillin, ethyl vanillin, coumarin, tonalid, calone, heliotropene, musk xylol, cedrol, musk ketone, benzophenone, raspberry ketone, methyl naphthyl ketone beta, phenyl ethyl salicylate, veltol, maltol, maple lactone, proeugenol acetate, evernyl, and the like.
