  • Candles have been used for centuries as a source of light and for their aesthetic appeal.
  • Paraffin wax has been traditionally used in making candle wax, which conventionally comprises 80 to 100% paraffin wax. It comes in various grades and melting points, and is predominantly composed of fully saturated long chain hydrocarbons. Although it is widely used in the candle industry, paraffin wax has a long cooling rate and is subject to pitting and bubbles arising during the candle manufacturing process. Paraffin wax is also a petroleum by-product and is known to produce toxins, black soot and carcinogens. It would therefore be advantageous to eliminate or reduce the paraffin wax used in candles in favour of a “green” alternative, and especially in favour of vegetable derived raw materials and ingredients.
  • Vegetable oil is usually liquid at room temperature, thus it needs to be modified so that it can turn into solid form wax at room temperature.
  • One way of doing this is to hydrogenate the vegetable oil by adding hydrogen atoms to the double bonds of the fatty acid in the molecule of oil so as to increase the melting point of the triglyceride. The melting point rises as the oil is saturated and the double bonds eliminated.

If the hydrogenated oil is kept at high temperatures for a long period (2-3 weeks), it will usually darken and change colour. The transportion and storage costs and troubles are especially concerning during the cold winter since hydrogenated oil can easily solidify and thereby block pipes, thus causing logistical and production planning problems.

Unsaturated vegetable oils (and fatty acids) can be converted to saturated vegetable oils (and fatty acids) by hydrogenation, which involves the process of addition of diatomic hydrogen at high pressure and in the presence of catalysts which are very expensive and not environmentally friendly.

Description

    FIELD OF THE INVENTION
  • This invention relates to candle compositions. In particular, this invention relates to candle compositions having non-hydrogenated oil and a process for making a candle composition having non-hydrogenated oil.
  • BACKGROUND OF THE INVENTION
  • Candles have been used for centuries as a source of light and for their aesthetic appeal.
  • Paraffin wax has been traditionally used in making candle wax, which conventionally comprises 80 to 100% paraffin wax. It comes in various grades and melting points, and is predominantly composed of fully saturated long chain hydrocarbons. Although it is widely used in the candle industry, paraffin wax has a long cooling rate and is subject to pitting and bubbles arising during the candle manufacturing process. Paraffin wax is also a petroleum by-product and is known to produce toxins, black soot and carcinogens. It would therefore be advantageous to eliminate or reduce the paraffin wax used in candles in favour of a “green” alternative, and especially in favour of vegetable derived raw materials and ingredients.
  • Some manufacturers in the candle industry have started using vegetable oil as a main ingredient of wax for candle production. Vegetable oil is usually liquid at room temperature, thus it needs to be modified so that it can turn into solid form wax at room temperature. One way of doing this is to hydrogenate the vegetable oil by adding hydrogen atoms to the double bonds of the fatty acid in the molecule of oil so as to increase the melting point of the triglyceride. The melting point rises as the oil is saturated and the double bonds eliminated. Another way to modify the liquid vegetable oil into solid form wax is to convert the unsaturated cis-fats into trans-unsaturated trans-fats. Unsaturated trans-fats have higher melting point and are in solid form at normal room temperature. Conversely, the unsaturated cis-fats usually have lower melting point and will be in liquid form even at or below 0° C. During the vegetable oil hydrogenation process, some of the cis-form triglyceride converts to tran-form at the high temperature and with the addition of the catalyst of Nickel or noble metal salts. The trans-form vegetable oil contributes partially to the solidifying of partially-hydrogenated vegetable oil (commercially called shortening).
  • The use of partially or wholly hydrogenated vegetable oil as the main ingredient of wax for candle production is advantageous because it is a solid at room temperature. However, the use of hydrogenated vegetable oil also has a number of disadvantages, including high consumption of energy during the hydrogenation process, and high costs for transportation, storage and handling because hydrogenated vegetable oil is solid at room temperature and can oxidize easily. If the hydrogenated oil is kept at high temperatures for a long period (2-3 weeks), it will usually darken and change colour. The transportion and storage costs and troubles are especially concerning during the cold winter since hydrogenated oil can easily solidify and thereby block pipes, thus causing logistical and production planning problems. The hydrogenation process also produces trans-fats, which might be a health concern when the candle/wax is used in thermotherapy. The trace residue of the catalysts (nickle or platinum) from the hydrogenation process is harmful to the metal equipments (wax storage container, tanks, pipes, etc.) and is also a health issue.
  • The main constituent of vegetable oil is triglyceride, which is essentially a glyceride in which the glycerol is esterified with three fatty acids. The chemical formula of triglyceride is CH2COOR—CHCOOR′—CH2—COOR″, wherein R, R′ and R″ are long alkyl chains and the three fatty acids RCOOH, R′COOH and R″COOH may all vary.
  • Vegetable oils which contain more unsaturated fatty acids remain in the liquid phase at temperatures at which saturated vegetable oils are solid. Unsaturated vegetable oils (and fatty acids) can be converted to saturated vegetable oils (and fatty acids) by hydrogenation, which involves the process of addition of diatomic hydrogen at high pressure and in the presence of catalysts which are very expensive and not environmentally friendly. The elimination of double bonds in the triglyceride by adding hydrogen atoms increases the degree of saturation, thereby raising the oil's melting point and viscosity.
  • Unsaturated vegetable oils usually stay in liquid form at a point between −18° C. and −5° C., depending on the type of oil, and have an Iodine value of 77-178. There is therefore a need to turn unsaturated liquid vegetable oils into a solid without using chemical processing, thereby allowing the mixture to be modified for candle production purposes. Such a candle would be easier to burn due to its low viscosity with suitable melting point and therefore has a safety advantage.
