Definitions

  • the present invention generally relates to the production of a wax composition for vegetable candles based on at least partially hydrogenated food-grade rapeseed ( Brassica Napus ) oil.
  • Rapeseed oil has the advantage of European production, without GMOs, unlike oil from another source such as palm or soya. Following a process of partial hydrogenation of rapeseed oil, a vegetable fat with an adequate melting point (typically between 40 to 60°C) is obtained for use as a candle base for perfumed containers.
  • rapeseed oil does however have a significant texture problem because it is very rich in stearic type fatty acid triglycerides (saturated or unsaturated C18), which generates significant and expansive crystallizations resulting in a cabbage-shaped appearance.
  • - flower (usually designated by the expression in English "blooming effect ”) , as illustrated by the figure 1 below.
  • composition of wax for vegetable candle consisting of a major part of an at least partially hydrogenated food rapeseed oil, a minor but significant contribution of long-chain fatty alcohol C18 , C20 and C22 (preferably of rapeseed origin or equivalent) and optionally, a supply of monoglycerides or diglycerides (preferably of rapeseed origin or equivalent).
  • rapeseed oil having a quality in accordance with French decree No. 78-840 of August 9, 1978 incorporating European directive 76/621 / EC, that is to say a rapeseed oil having a maximum rate of 5% in erucic acid.
  • Edible rapeseed oil may also be described as “low erucic acid rapeseed oil” as described in Codex Alimentarius CXS 210-1999 (hereinafter referred to as Appendix 4).
  • rapeseed oil By at least partially hydrogenated rapeseed oil, a rapeseed oil as obtained at the end of a process of chemical transformation by partial or total hydrogenation of the unsaturations of the fatty acids and which makes it possible to obtain a fat (therefore solid to ambient temperature).
  • the degree of hydrogenation of the rapeseed oil is defined by its melting point and the iodine value, the melting point being between 40 and 75° C. (for a rapeseed oil completely hydrogenated), and in particular between 40 and 60°C when the rapeseed oil is only partially hydrogenated, and the iodine number being less than 80 (the iodine number 0 corresponding to a rapeseed oil fully hydrogenated).
  • mixture of fatty alcohols comprising C18, C20 and C22 long-chain fatty alcohols
  • a mixture of fatty alcohols obtained from an oil comprising a mixture of fatty acids in C18, C20 and C22. in particular by hydrogenation and transesterification.
  • mixture of C18 and C22 monoglycerides and/or diglycerides is meant, within the meaning of the present invention, a mixture of monoglycerides and/or diglycerides obtained by lipochemical transformation and recombination of oils comprising a mixture of C18 fatty acids , and C22.
  • a mixture of monoglycerides and/or diglycerides at a rate of 0 to 10% makes it possible to improve the surface (as illustrated by the figure 2 below), which is then smooth and homogeneous and could be altered by additives such as perfumes.
  • the mixture of fatty alcohols can be obtained by hydrogenation and transesterification of an oil chosen from rapeseed oil rich in erucic acid (usually designated by the acronym in English language HEAR for “ High Erucic Acid Rape ”) or mustard oil, or any other oil that has the same fatty acid profile.
  • rapeseed oil rich in erucic acid usually designated by the acronym in English language HEAR for “ High Erucic Acid Rape ”
  • mustard oil or any other oil that has the same fatty acid profile.
  • Rapeseed oil rich in erucic acid means, within the meaning of the present invention, a rapeseed oil comprising at least 40% by weight of erucic acid (C22) relative to the total weight.
  • rapeseed oil low in erucic acid means, within the meaning of the present invention, a rapeseed oil comprising less than 10% by weight of erucic acid (C22) relative to the total weight.
  • rapeseed oils rich in erucic acid are transformed into fatty alcohol, in particular by hydrogenation and trans-esterification processes, a more diversified wax composition is obtained and contains long-chain fatty alcohols (of the C18 type, C20 and C22).
  • the mixture of monoglycerides and/or diglycerides is obtained by saponification, hydrogenation and esterification of an oil chosen from rapeseed oils rich in erucic acid, rapeseed oils low in erucic acid, mustard oil, and their mixtures.
  • the wax composition according to the invention may also comprise one or more additives present in a proportion of 1 to 15% by weight relative to the total weight of said composition, said additive(s) being chosen from natural or synthetic fat-soluble perfume raw materials, repellent agents, insecticidal agents, biocidal active substances, anti-odor agents, dyes and antioxidant stabilizers.
  • the wax composition according to the invention may advantageously comprise 2 to 12% by weight relative to the total weight of the wax composition of one or several perfume raw materials, whether natural or synthetic.
  • perfume raw materials that can be used in the wax composition according to the invention, mention may in particular be made of essential oils such as essential oil of lavender or any fat-soluble perfume concentrate usually used in wax compositions for candle.
  • the present invention also relates to a vegetable candle comprising at least one wick (preferably substantially straight) partially embedded in the wax composition according to the invention.
  • wick is meant, within the meaning of the present invention, an element which supplies the flame with fuel by capillarity.
  • the wick can be made of cotton, wood, paper, or fibers and in particular cellulose fibers.
  • the candles can be container candles (i.e. the wax composition is poured into a container which supports it) or free-standing candles without a container and which have been poured into molds and are removed from the candle.
  • step A) of melting may be carried out by maintaining the mixture of the various constituents of the composition under stirring to promote a homogeneous mixture.
  • step B) casting in containers (for container candles) or molds (for self-supporting candles) can be carried out whatever the temperature, for example that of the mixture of the various constituents during melting step A or at a lower temperature if the hot wax has the necessary fluidity to be cast.
  • one or more additional castings can be made to compensate for the loss of volume during solidification (digging phenomenon) and to have a flatter surface.
  • the present invention can also be implemented by conventional processes for the manufacture of candles such as the constitution of powder or shavings and their pressing or their extrusion.
  • a vegetable candle was produced in accordance with the method according to the invention described above from a candle wax composition comprising 75% by weight of an at least partially hydrogenated food-grade rapeseed oil and 25% by weight relative to the total weight of the wax composition of a mixture of fatty alcohols comprising long-chain C18, C20 and C22 fatty alcohols (cf. candle 4 in table 1).
  • 3 vegetable candles were produced in accordance with the method of the invention from only an at least partially hydrogenated food-type rapeseed oil (candle 1), as well as from a wax composition for a candle comprising 75% by weight of an at least partially hydrogenated food-grade rapeseed oil and 25% by weight, relative to the total weight of the wax composition, of a single C18 fatty alcohol (candle 2) or C22 (candle 3).
