Polymerized wax candles

Abstract

A candle made with a wax base and a synthetic thermoplastic rubber copolymer. The wax base may be prepared from a variety of sources including petroleum sources, animal sources, vegetable sources, synthetic sources, and blends thereof. The synthetic thermoplastic rubber copolymer may be a diblock, triblock, radial block, multiblock copolymers, and blends thereof. In addition to the wax base and the synthetic thermoplastic rubber copolymer, candles made according to the invention can also include stabilizers, fragrances, dyes as well as other standard candle additives. Moreover, candles produced according to the invention have several cost saving advantages. The addition of the synthetic thermoplastic rubber copolymer allows for the production of high quality candles while utilizing less expensive wax bases. Additionally, disclosed candles decrease processing times and percent defects.

Description

[0001] Candles comprising a wax base and a copolymer of synthetic thermoplastic rubber copolymer additives are disclosed. The copolymer additive is useful for binding excess oil within the candle thereby allowing for the production of quality candles from less expensive base wax. Methods of manufacturing candles comprising a wax base and a copolymer of synthetic thermoplastic rubber additives are also disclosed.BACKGROUND OF THE RELATED ART[0002] Candles have long since been used as an accepted method of giving light, heat, scent, or for celebration or votive purposes. Candles made from a variety of wax bases are well known within the art. Typically, a wax base is derived from petroleum sources, vegetable sources, animal sources, synthetic sources, or some mixture thereof. The wax materials of candles are typically of high quality having a low amount oil therein. A low amount of oil within the candle is associated with a high quality candle.[0003] Despite the low costs of using crud...

AI Technical Summary

Benefits of technology

[0007] A candle utilizing a wax base and a synthetic thermoplastic rubber copolymer is also disclosed. The wax base may come from economical sources such as petroleum sources, vegetable sources, animal sources, synthetic sources or mixtures thereof. Further, the wax base may or may not be classified as a "crude wax". The copolymer used in conjunction with the candle may be a diblock, triblock, radial block, or combinations of diblock, triblock and radial block copolymers. The addition of the copolymer to the wax base binds the oil within the wax, thereby permitting the production of candles with more cost effective materials. It is therefore an object of the invention to prepare candles with lower cost waxes which are presently unable to be used in candle-making preparation.

[0009] As an additional method of cost savings, candles produced according to this invention reduce processing times and percent defects. Moreover, the candles can be produced using standard candle manufacturing facilities. As such it is an object of this invention to produce candles utilizing an optimized manufacturing process.

[0010] In addition to the cost saving benefits, the addition of the copolymer has been found to alter the crystalline structure of the wax bases thereby allowing for the manipulation of the burn rate of the candles. The burn rate manipulation is achieved because the altered crystalline structure provides multiple temperature gradients throughout the candle. It is therefore an object of the invention to provide candles that have longer burn times than conventional candles. In addition to longer burn times, the multiple temperature gradients of the candle provides safety benefits by preventing spillovers because the edges of the candle are substantially cooler than the center pool.

Problems solved by technology

One of the lower cost waxes that are presently not useful in the candle making process are low-melt waxes.

Despite their lower cost, these low-melt waxes are not used prevalently because they may melt during shipping during hot months.
