Benefits of technology

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.

example 1

[0024] A candle having a wax base made from petroleum matter was prepared in accordance with the described protocol. The wax base is about 78.75% by weight of the candle composition. Paraffin wax sold by Exxon / Mobil under the trade name Parvan.RTM. 129 and micro-crystalline wax sold by Bareco Products under the trade name Be Square.RTM. are examples of the types of petroleum matter that may be used to prepare the wax base according to this example. The synthetic thermoplastic rubber copolymer used in this example is a styrene-ethylene-styrene block copolymer. Sold by Shell Chemical Company under the tradename KRATON.RTM. 1652, the synthetic thermoplastic rubber copolymer is present in an amount of about 5% by weight. Additionally, stearic acid, sold under the tradename Emersol.RTM. 7036 by the Cognis Company, may be present in an amount of about 1% by weight. Other polymers, such as polyethylene sold under the trade name Vybar.RTM. 103 by Baker-Petrolite is also present in an amount...

example 2

[0025] A candle with a wax base made from vegetable matter is prepared in accordance with the described protocol. The wax base is present in an amount of about 99% by weight, and may be vegetable fatty acids, soybean wax, beeswax or other vegetable based sources. Additionally, a synthetic thermoplastic copolymer such as styrene-ethylene-styrene block copolymer, is also present in an amount of about 1% by weight. KRATON.RTM.1652 sold by the Shell Chemical Company is a suitable example of such a copolymer.

example 3

[0026] A candle with a wax base made from animal-fat matter is prepared in accordance with the described protocol. The wax base is present in an amount of about 98% by weight. Suitable animal-fat sources include tallow base fatty acids. Additionally, a synthetic thermoplastic copolymer such as KRATON.RTM. 1652 is also present in an amount of about 2% by weight.

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...
