Definitions
- the present invention relates to a colored candle and a method for manufacturing thereof.
- Typical candles are formed of a solid body of a fuel source in which a wick is embedded.
- Fuel sources for candles typically waxes, can cover a broad spectrum of products that include petroleum-, animal-, vegetable- and synthetic-based materials. Waxes refined from petroleum are used most commonly. However, other types of waxes have become popular in the last number of years - such as vegetable or plant based waxes such as palm stearin, hydrogenated vegetable oils and waxes from insects such as beeswax.

Description
- The present invention relates to a colored candle and a method for manufacturing thereof.
- Typical candles are formed of a solid body of a fuel source in which a wick is embedded. Fuel sources for candles, typically waxes, can cover a broad spectrum of products that include petroleum-, animal-, vegetable- and synthetic-based materials. Waxes refined from petroleum are used most commonly. However, other types of waxes have become popular in the last number of years - such as vegetable or plant based waxes such as palm stearin, hydrogenated vegetable oils and waxes from insects such as beeswax.
- A typical process for manufacturing candles involves filling a mold, in which a wick has been positioned, with molten wax, allowing the wax to cool and then removing the formed candle from the mold. Another known technique involves compression molding, wherein the candle is made by using a powered wax or a mixture of powered waxes.

US20100132250 . The method relates to manufacturing of compressed candles involving charging the mold with a prilled wax particles, in a single step, comprising hydrogenated natural oil and additives including coloring agents, compressing the prilled wax particles followed by thermally fusing an outer layer of the compressed prilled wax particles to form a thermally fused outer layer of the colored candle. - A US patent application
US2012052455 describes a candle, in which coloring agents are limited to the outer peripheral surface of the candle and method of its production. The method involves dispensing, on an inner mold cavity surface, a wetting agent and dispensing into said cavity a coloring agent in a finely divided dry form and causing a portion of the coloring agent to adhere to the wetting agent, followed by dispensing a combustible candle composition into the mold cavity to form the colored candle. - The process of dyeing candles with over-dipping technique requires using large amounts of coloring additives released in molten wax. Moreover, candles manufactured this way usually lose their uniform color during burning process, as the outer colored layer tends to peel off or burn together with the candle core.
- In turn, uniform color characteristic of candles obtained by dyeing the whole volume of the wax mass before preparing the candle core, requires production of large amounts of wax mass having a predetermined color. This necessitates fabrication of candles having the same color within the whole production batch. In consequence, changing the color of produced candles requires time-consuming cleaning of machines arranged in the production line, as well as storage of residual colored wax mass to be used, which may further lead to deterioration of wax quality.
- Therefore, there exists a need for developing a method for manufacturing colored wax candles, in which the manufacturing process may be performed so that the candles color may be changed more easily within a production batch, without undue labor.
- The object of the invention is a method for manufacturing a colored candle, comprising the steps of: providing a fragmented, non-opaque solid fuel; compression molding the fragmented solid fuel to form a candle core; treating the candle core with a liquid colorant solution comprising: a solvent or a mixture of solvents based on natural compounds in the amount of from 97 wt. % to 99,9 wt. % and a liquid colorant or a liquid colorant composition of a fat base in amount of from 0,1 wt. % to 3 wt. %; and allowing the liquid colorant solution to penetrate the candle core volume.
- Preferably, the candle core is treated with the liquid colorant solution by immersing the candle core in a bath with colorant solution.
- Preferably, the method further comprises drying the candle core after being treated with the liquid colorant solution.
- Preferably, the method further comprises coating the treated candle core with a molten, non-opaque solid fuel.
- Preferably, the molten, non-opaque solid fuel has the same composition as the fragmented, non-opaque solid fuel.
- Preferably, the solvent is selected from the group consisting of natural esters.
- The object of the invention is also a colored candle manufactured according to the method of any of previous claims.
- The present invention is shown by means of an exemplary embodiment shown in a drawing, wherein:
-
Fig. 1 is a flow chart showing the process steps of the method of producing colored candles; -
Figs. 2A, 2B show schematic cross-sectional views of a colored candle. - There is disclosed herein a method for manufacturing a colored candle having a relatively homogenous colorant distribution in the candle core. The candle is formed by using a known compression molding technology. The presented method involves the use of raw materials (fuels) which are colorless, non-opaque, at least translucent, and preferably transparent in a solid phase at room temperature. For example, suitable raw materials are the known translucent, and preferably transparent, synthetic or natural waxes or mixtures thereof, such as, but not limited to: paraffin, palm stearin and fully hydrogenated palm oil and their compositions. The following are non-limiting examples of the raw material composition:
- 60 wt. % of palm stearin and 40 wt. % of paraffin
- 70 wt. % of palm stearin and 30 wt. % of fully hydrogenated palm oil
- 100 wt. % of paraffin
- 60 wt. % of palm stearin and 20 wt. % of paraffin and 20 wt. % of animal fat
- 80 wt. % of palm stearin and 20 wt.% of animal fat
-
Fig. 1 presents a flow-chart of the process for manufacturing colored candles. At thefirst stage 11, solid waxes are grinded into smaller fragments and mixed uniformly using a known grinding technology. The fragments have a grain size from 0,05 mm to 15mm. In one example, the fragments may have a form of a powder, such as fragments having a size below 1 mm. In other embodiment, the fragments may be a mix of a powder and larger particles. In yet another embodiment, the fragments may be only larger particles, such as particles above 1 mm. In this stage, different additives, such as fragrances, can be added to the raw material. Then, the obtained fragments of fuel composition enters thecompression molding station 12 wherein the fuel composition is compressed in the compression mold to form a colorless, non-opaque, translucent or preferably transparent candle core provided with a wick. The density of the candle core depends on the compression force applied at the mold. During compression, the mold is preferably non-heated or heated up to the temperature not exceeding +60 °C in order to achieve the proper pore characteristic of the compression candle core, as well as its coherency. - In the following step, the candle core is supplied to a
dyeing station 13 and treated with a colorant solution. Treating of the translucent or transparent candle core with the colorant may be accomplished by any suitable known technique, such as spraying or preferably immersing. The colorant solution comprises a solvent or a solvent composition based on organic volatiles ingredients capable of dissolve fat compounds and a liquid hydrophobic colorant or liquid hydrophobic colorant mixture of fat base. The liquid colorants used may be either dyes or pigments or a mixture thereof. The weight ratio of the solvent component to the colorant component may vary from 97:3 to 99,9:0,1. For example, the dyeing composition may comprise a solvent in amount of 99 wt. % and a colorant agent in amount of 1 wt. %, or the dyeing composition may comprise a solvent in amount of 98 wt. % and a colorant agent in amount of 2 wt. %. The percentage of the colorant affects the color intensity of produced candles. - Preferably, the
dyeing process 13 according to the invention is accomplished as follows. The transparent or translucent candle cores produced instep 12 are provided into a bath with the colorant solution under mild conditions. Preferably, the atmospheric pressure is maintained during all the dyeing process. Alternatively, increased pressure may be applied. The colorant solution temperature is maintained at the room level, e.g. about 20°C during the dyeing. The bath treatment is preferably executed for 3 - 6 seconds. After the treatment time, the candle cores are removed from the bath. The treatment time affects the shade of color of the candle. When it is desired to produce candles of a lighter shade, the bathing time should be shorter. Extension of the bathing period is advised when candles of larger diameter are dyed. - After treating with the colorant solution, the candles are subject to a
drying process 14. Herein, candles may be air-dried in an ambient temperature or the excess of the colorant solution may be removed form the outer surface of the candle by a compressed air stream. During thedrying process 14, the colorant solution that was absorbed by the candle core during bathing 13, penetrates the candle core and is incorporated into the deeper core regions. The coherency and core density affect the depth of core penetration by the coloring agent. The penetration process may continue even after completion of the drying process, e.g. during storage of the candle. The dried candle core may comprise from 1% to 10% of the colorant solution, preferably about 5%. - In the
next step 15, the candle may by optionally coated with a transparent or translucent coating material, for example the same material that was used for the candle core. Preferably, within the manufacturing line, a part of the mixture of raw material obtained at the grindingstation 11 is added as a coating material at thestation 15. The coating material (e.g. a wax composition) is melted, prior to being added, by using a suitable melting technique such as heating. The candle core, prior to being coated, may be put into a container made from a material sufficiently resistant for flame and heat released during burning of the candle, preferably translucent, or more preferably transparent, such as a glass jar. Thecoating process 15 is implemented by applying the melted wax composition onto the colored candle core, so that it creates an outer translucent or preferablytransparent layer 24, as shown inFig. 2B . The appliedlayer 24 is optional as it smoothes the candle surface. In order to make the candle with more porous surface, thiscoating step 15 can be omitted, as for the candle 20 shown inFig. 2A . -
Fig. 2A-2B shows exemplary cross-sectional views of the candle 20 manufactured according to the described method. The candle core 22 is provided with the wick 21. The distribution of the coloring agent is schematically shown asdots 23. In the example shown, the colorant solution comprises about 5 wt. % of the colored candle, wherein the colorant agent is distributed substantially uniformly within the candle core of about 80% of the external candle core volume. Grater concentration of the colorant agent is distributed near to the core surface and decreases uniformly towards the core center. - A raw material composition, comprising a mixture of natural and synthetic transparent waxes: 60 wt. % of palm stearin and 40 wt. % of paraffin, was grinded to a form of a fine powder. The powder was formed into the shape of a candle by compression molding. Next, the obtained core was introduced for 3 seconds into a bath with a colorant solution consisting of a solvent in the amount of 99 wt. % and of a liquid dye of fat base in the amount of 1 wt. % of the colorant solution. Then, the candle core was naturally air-dried in the room temperature for 10 minutes. After absorption of the colorant solution (during the bath and air-drying) the colored core was put into a glass jar and coated with molten wax of the same composition as the candle core to form the outer candle layer.
- The method described above enables making candles of different colors within one production batch without necessity of exchanging the whole batch of the raw material processed in the manufacturing line as well as time consuming cleaning the machines or expensive storing the residual wax mass. The candles obtained according to presented invention show substantially homogenous colorants distribution, and they do not lose their uniform color appearance during the burning process.
