Definitions

  • the invention relates to a fuel composition for a candle, comprising vegetable oil, candelilla wax and stearic acid, and a process for producing the same.
  • the main candle raw materials used are paraffins (saturated hydrocarbons), stearins (fatty acids), beeswax and triglycerides (hardened or partially hydrogenated fats), alone or in a mixture.
  • n-paraffins is used as a collective term for saturated aliphatic hydrocarbons, where straight-chain or branched chains (isoparaffins) can be present.
  • the n-paraffins are solid and waxy from Cn onwards.
  • Waxes a distinction is made between natural waxes of plant or animal origin, chemically modified and synthetic waxes. Waxes can normally be kneaded at 20°C, especially waxes with a softening point such as paraffin or beeswax, above 40°C they melt without decomposition and they are solid to brittle and hard and coarse to fine crystalline.
  • Step is generally understood to mean a mixture of stearic acid and palmitic acid which results from the fatty acid mixture formed during lipolysis after the liquid oleic acid has been separated off and cleaned.
  • a candle In most cases, a candle consists of a wick embedded in a block of wax, with the wax providing the fuel for the candle to burn.
  • Paraffin has many properties that make it suitable for use in a candle. Paraffin, as used in candles, is typically highly refined and is in a crystalline state at room temperature. Paraffin-based candles are typically solid in consistency and may be formed into a free-standing columnar structure called a pillar candle, which is then placed on candlesticks and the like.
  • paraffin is an inexpensive raw material and meets most of the burning needs of a candle, making it an economically attractive choice candle material makes.
  • paraffin-based candles have the disadvantage that they are based on a non-renewable material.
  • burning paraffin candles releases soot and other pollutants that can be harmful to health and the environment. Soot can cause respiratory problems and aggravate diseases such as cardiovascular problems.
  • the products of combustion can damage works of art, such as those where candles are lit during religious worship, and their preservation can be impaired.
  • paraffin since paraffin is not a biodegradable product, the unburned residue of such candles pollutes and harms the environment.
  • US Pat. No. 6,645,261 relates to candle waxes consisting of palmitic acid and hardened vegetable oil.
  • KR 101976807 Bl discloses a liquid candle composition of the gel type, which consists of 78% by weight of vegetable oil, 15% by weight of fragrant plant parts (e.g. lavender), 2% by weight of candelilla wax and 1-2% by weight of each color pigment, propolis and essential oil.
  • This composition is placed in any ornamental container fitted with a fixed wick and serves as a home decor in addition to its function as a scented candle.
  • a solid candle composition is known from US Pat.
  • vegetable oil e.g. corn oil, palm oil or sunflower oil
  • fragrance 0-1 parts by weight of at least one antioxidant
  • the object of the invention is to provide an inexpensive fuel composition for a candle which consists of renewable, biodegradable and readily available raw materials.
  • This ecological composition should also be suitable both for indoor use and for outdoor use, eg for cemetery candles, should burn almost soot-free and have a burning time and performance that is at least equivalent to that of a paraffin candle. Furthermore, compared to the state of Technique in the industrial production of the fuel composition time and cost savings can be achieved.
  • the fuel composition for a candle comprising vegetable oil, candelilla wax and stearic acid is creamy in consistency.
  • the creamy consistency of the fuel composition makes it possible to provide a candle which is not based on paraffin or petroleum products, but which nevertheless has physical and chemical stability and which also allows outdoor use at temperatures between -20°C and 40°C.
  • the fuel composition of vegetable oil, candelilla wax and stearic acid according to the invention is also odorless and non-toxic, burns without soot and pollutants and, in particular, unlike most conventional candle materials, is biodegradable.
  • the candelilla wax contained in the fuel composition according to the invention acts as a structuring or lipid thickening agent.
  • the formation of crystals in the form of platelets creates a network that can "hold back" oil. This results in a soft, homogeneous and creamy consistency.
  • the fuel composition also includes stearic acid, which acts as a consistency agent that contributes to compaction.
  • the stearic acid contributes to the hardness of the fuel composition and also increases the burn time.
  • the stearic acid can provide better distribution of colorants and fixation of essences if such additional materials are desired in the fuel composition.
  • the fuel composition comprises 78-94% by weight vegetable oil, 3-12% by weight candelilla wax and 3-15% by weight stearic acid.
  • the proportion of vegetable oil is 85-92% by weight, preferably 88-91% by weight, in particular 90% by weight
  • the proportion of candelilla wax is 4-10% by weight, preferably 5- 7% by weight, in particular 5% by weight
  • the proportion of stearic acid is 4-12% by weight, preferably 5-8% by weight, in particular 5% by weight.
  • the vegetable oil is selected from corn oil, sunflower oil, linseed oil, soybean oil, palm oil, wheat germ oil, safflower oil, camelina oil and mixtures thereof.
  • Corn germ oil is particularly preferably used as the vegetable oil for the fuel composition. Unlike the quantitatively limited petroleum products, corn oil is an abundant and renewable resource because corn can be grown in a wide variety of climatic conditions. In contrast to paraffin, it is regenerative, biodegradable, neutral in terms of CO2 emissions and free of sulfur and heavy metals. It is also non-volatile and has a flash point of around 200°C, meaning it is neither flammable nor explosive and can be stored for long periods without risk.
  • the stearic acid is preferably a vegetable stearic acid.
  • the fuel material for the candle is made entirely of plant-based components.
  • Fuel composition also pigments, fragrances and/or essential oils, the total proportion of pigments, fragrances and/or essential oils being ⁇ 2.5% by weight.
  • these additional ingredients of the fuel composition are preferably of plant or animal origin.
  • the additional ingredients are preferably selected in such a way that soot and pollutant-free combustion of the fuel composition remains guaranteed.
  • Another aspect of the invention relates to a method for producing a fuel composition according to the invention, which comprises the following steps:
  • the addition of the candelilla wax to the vegetable oil triggers an aggregation process which, by forming a three-dimensional network, causes the oil to be retained or collected.
  • This structuring is further reinforced by the addition of stearic acid, so that the oil is immobilized or oil migration is prevented and thus a creamy consistency is achieved.
  • the stearic acid can also optimally integrate into the oleogel mixture and unfold its effect.
  • a fuel composition of creamy consistency is obtained. Cooling down and putting the candle to rest can expediently already take place in candle containers equipped with a wick, which are preferably made of a biodegradable material. If final filling is planned for a later date, the fuel composition can be made soft or processable for compression or press molding by heating to a temperature of about 35-40° C Piston filling system, candle cups or other suitable containers, where it regains its physically stable consistency after cooling.
  • a further aspect of the invention relates to a candle, in particular a cemetery candle, which comprises a fuel composition according to the invention, as described above.
  • the candle also includes a biodegradable wick and a biodegradable wrapper, such as a biodegradable bioplastic candle cup.
  • the fuel composition has solidified in the candle jar and has a creamy consistency.
  • the candle material is physically stable and the "cream” does not run out of the container even if it is turned upside down (turned upside down) and the container is slightly knocked.
  • the candle is physically stable to temperature variations from -20°C to 40°C.
  • the candle produced according to the invention burns odorless and does not emit soot or other chemical pollutants. Their burning power corresponds to that of a paraffin candle of the same volume.
  • the burning time of the candle made from the fuel composition according to the invention is 12 min/g and is therefore longer than that of a paraffin candle (10 min/g on average).
  • the residues of the fuel composition remaining after the candle has burned down are completely biodegradable.
  • 88 g of corn oil are heated to 80° C. in a container equipped with a stirrer and heater. After reaching this temperature, 5 g of candelilla wax are added and the mixture is stirred while maintaining the temperature of 80°C in order to dissolve any solid particles of the structuring agent in the corn oil. After about 5 minutes the wax is completely dissolved in the vegetable oil. Thereafter, 5 g of stearic acid are added to the mixture while stirring and the temperature is further maintained at 80°C.
  • a colored pigment is added and mixed into the composition.
  • 1 g essential oil e.g. lavender oil
  • the finished mixture is then poured into a jar with a candle wick and left to stand for 24 hours.
  • the colored fuel composition has solidified in the candle vessel and has a creamy consistency and a pleasant scent.
  • the candle material is physically stable and burns without releasing soot and pollutants.
