Description

Domaine technique de l'inventionTechnical field of the invention

La présente invention concerne de manière générale la réalisation d'une composition de cire pour bougie végétale à base d'huile de colza (Brassica Napus) de type alimentaire au moins partiellement hydrogénée. L'invention est définie par les revendications 1-12 attachées.The present invention relates generally to the production of a vegetable wax composition for candles based on food-grade rapeseed ( Brassica napus ) oil, at least partially hydrogenated. The invention is defined by the attached claims 1-12.

Arrière-plan techniqueTechnical background

L'huile de colza a l'avantage d'une production européenne, sans OGM au contraire d'huile provenant d'une autre source telle que la palme ou le soja. Suite à un processus d'hydrogénation partielle de l'huile de colza, on obtient une graisse végétale de point de fusion adéquat (typiquement comprise entre 40 à 60°C) pour une utilisation en tant que base bougie pour contenant parfumé. Toutefois, l'huile de colza présente cependant un problème important de texture car elle est très riche en triglycérides d'acide gras type stéarique (C18 saturé ou insaturé), ce qui génère des cristallisations importantes et expansives résultant en un aspect en forme de chou-fleur (usuellement désignée par l'expression en langue anglaise «blooming effect»), comme illustré par la figure 1 ci-après.Rapeseed oil has the advantage of being produced in Europe and is GMO-free, unlike oils from other sources such as palm or soy. Following a partial hydrogenation process, rapeseed oil yields a vegetable fat with a suitable melting point (typically between 40 and 60°C) for use as a base for scented candles. However, rapeseed oil presents a significant textural problem because it is very rich in stearic acid triglycerides (saturated or unsaturated C18), which generates significant and expansive crystallization resulting in a cauliflower-like appearance (commonly referred to as the "blooming effect" ), as illustrated by the figure 1 below.

Pour y remédier, le demandeur a mis au point une composition de cire pour bougie végétale constituée d'une part majoritaire d'une huile de colza alimentaire au moins partiellement hydrogénée, d'un apport minoritaire mais important en alcool gras à longue chaine en C18, C20 et C22 (de préférence d'origine colza ou équivalent) et optionnellement, un apport en monoglycérides ou diglycérides (de préférence d'origine colza ou équivalent). US2004250464 décrit une composition pour bougie comprenant un mélange d'huiles végétales partiellement hydrogénées solides et liquides, et contenant en outre un agent durcisseur, ainsi qu'un colorant, des huiles parfumées et/ou des agents scintillants. La composition comprend (parties en poids) : une huile végétale solide partiellement hydrogénée (40 - 65), un agent durcisseur d'origine végétale (8 - 22) et une huile végétale crémeuse partiellement hydrogénée (20 - 31).To remedy this, the applicant has developed a vegetable candle wax composition consisting of a major part of a food rapeseed oil at least partially hydrogenated, a minor but significant contribution of long chain fatty alcohols in C18, C20 and C22 (preferably of rapeseed origin or equivalent) and optionally, a contribution of monoglycerides or diglycerides (preferably of rapeseed origin or equivalent). US2004250464 Describes a candle composition comprising a mixture of partially hydrogenated solid and liquid vegetable oils, and further containing a hardening agent, as well as a colorant, fragrance oils, and/or glitter agents. The composition comprises (by weight): a partially hydrogenated solid vegetable oil (40-65%), a vegetable-derived hardening agent (8-22%), and a partially hydrogenated creamy vegetable oil (20-31).

Exposé de l'inventionDescription of the invention

Plus particulièrement, la présente invention a pour objet une composition de cire pour bougie végétale comprenant au moins 30% en poids par rapport au poids total de la composition de cire d'une huile de colza de type alimentaire au moins partiellement hydrogénée, ladite composition étant caractérisée en ce qu'elle comporte en outre :

  • 5 à 50 % en poids par rapport au poids total de la composition de cire d'un mélange d'alcools gras comprenant des alcools gras à longue chaine en C18, C20 et C22, ledit mélange d'alcools gras étant obtenu par hydrogénation et transestérification d'une huile comprenant un mélange d'acides gras en C18, C20 et C22,
  • 0 à 10 % en poids par rapport au poids total de la composition de cire d'un mélange de monoglycérides et/ou de diglycérides en C18et C22, ledit mélange de monoglycérides et/ou de diglycérides étant obtenu par transformation lipochimique et recombination d'huiles comprenant un mélange d'acides gras en C18, et C22, et
  • 0 à 15% en poids par rapport au poids total de la composition de cire d'un ou plusieurs additifs.
More particularly, the present invention relates to a vegetable wax composition comprising at least 30% by weight relative to the total weight of the wax composition of a food-grade rapeseed oil that is at least partially hydrogenated, said composition being characterized in that it further comprises:
  • 5 to 50% by weight relative to the total weight of the wax composition of a mixture of fatty alcohols comprising long-chain fatty alcohols in C18, C20 and C22, said mixture of fatty alcohols being obtained by hydrogenation and transesterification of an oil comprising a mixture of fatty acids in C18, C20 and C22,
  • 0 to 10% by weight relative to the total weight of the wax composition of a mixture of C18 and C22 monoglycerides and/or diglycerides, said mixture of monoglycerides and/or diglycerides being obtained by lipochemical transformation and recombination of oils comprising a mixture of C18 and C22 fatty acids, and
  • 0 to 15% by weight relative to the total weight of the wax composition of one or more additives.

Par huile de colza de type alimentaire, on entend, au sens de la présente invention, une huile de colza présentant une qualité conforme au décret français N°78-840 du 9 aout 1978 reprenant la directive européenne 76/621/CE, c'est-à-dire une huile de colza présentant un taux maximal de 5 % en acide érucique. L'huile de colza alimentaire peut aussi se décrire par « huile de colza à faible teneur en acide érucique » tel que décrite dans le codex alimentarius CXS 210-1999 (ci-après référencé comme étant l'Annexe 4).For the purposes of this invention, edible rapeseed oil is defined as rapeseed oil of a quality conforming to French Decree No. 78-840 of August 9, 1978, which transposed European Directive 76/621/EC, i.e., rapeseed oil with a maximum erucic acid content of 5%. 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 Annex 4).

Par huile de colza au moins partiellement hydrogénée, une huile de colza telle qu'obtenue à l'issue d'un procédé de transformation chimique par hydrogénation partielle ou totale des insaturations des acides gras et qui permet d'obtenir une graisse (donc solide à température ambiante). Dans la présente demande, le degré d'hydrogénation de l'huile de colza est défini par son point de fusion et l'indice d'iode, le point de de fusion étant compris entre 40 et 75°C (pour une huile de colza complètement hydrogénée), et notamment entre 40 et 60°C lorsque l'huile de colza n'est que partiellement hydrogénée, et l'indice d'iode étant inférieur à 80 (l'indice d'iode 0 correspondant à une huile de colza complètement hydrogénée).Rapeseed oil that is at least partially hydrogenated is defined as rapeseed oil obtained through a chemical transformation process involving the partial or total hydrogenation of fatty acid unsaturates, resulting in a fat (and therefore solid at room temperature). In this application, the degree of hydrogenation of the rapeseed oil is defined by its melting point and iodine value. The melting point is between 40 and 75°C (for fully hydrogenated rapeseed oil), and in particular between 40 and 60°C when the rapeseed oil is only partially hydrogenated. The iodine value is less than 80 (an iodine value of 0 corresponding to fully hydrogenated rapeseed oil).

Par mélange d'alcools gras comprenant des alcools gras à longue chaine en C18, C20 et C22, on entend, au sens de la présente invention un mélange d'alcools gras obtenu à partir d'une huile comprenant un mélange d'acides gras en C18, C20 et C22. notamment par hydrogénation et transestérification.For the purposes of this invention, a mixture of fatty alcohols comprising long-chain fatty alcohols in C18, C20 and C22 means 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.

Par mélange de monoglycérides et/ou de diglycérides en C18et C22, on entend, au sens de la présente invention, un mélange de monoglycérides et/ou de diglycérides obtenu par transformation lipochimique et recombination d'huiles comprenant un mélange d'acides gras en C18, et C22.For the purposes of this invention, a mixture of monoglycerides and/or diglycerides in C18 and C22 is understood to mean a mixture of monoglycerides and/or diglycerides obtained by lipochemical transformation and recombination of oils comprising a mixture of fatty acids in C18 and C22.

La présence, dans la composition de cire pour bougie végétale selon l'invention, de ce mélange d'alcools gras à raison de 5 à 50 % permet de modifier la cristallisation des triglycérides présents dans l'huile de colza.The presence, in the composition of vegetable candle wax according to the invention, of this mixture of fatty alcohols at a rate of 5 to 50% makes it possible to modify the crystallization of the triglycerides present in rapeseed oil.

La présence optionnelle, dans la composition de bougie parfumée, d'un mélange de monoglycérides et/ou de diglycérides à raison de 0 à 10 % permet d'améliorer la surface (comme illustré par la figure 2 ci-après), qui est alors lisse et homogène et pourrait être altérée par des additifs du type parfums.The optional presence, in the composition of scented candles, of a mixture of monoglycerides and/or diglycerides at a rate of 0 to 10% allows for an improvement in surface area (as illustrated by the figure 2 (see below), which is then smooth and homogeneous and could be altered by additives such as perfumes.

De préférence, dans la composition de cire selon l'invention :

  • l'huile de colza de type alimentaire au moins partiellement hydrogénée représente au moins 50% en poids par rapport au poids total de la composition de cire ;
  • ledit mélange d'alcools gras représente 15 à 40 % en poids par rapport au poids total de la composition de cire,
  • ledit mélange de monoglycérides et/ou de diglycérides représente 1 à 5 % en poids par rapport au poids total de la composition de cire.
Preferably, in the wax composition according to the invention:
  • Food-grade rapeseed oil, at least partially hydrogenated, represents at least 50% by weight relative to the total weight of the wax composition;
  • said mixture of fatty alcohols represents 15 to 40% by weight relative to the total weight of the wax composition,
  • said mixture of monoglycerides and/or diglycerides represents 1 to 5% by weight relative to the total weight of the wax composition.

De préférence, le mélange d'alcools gras peut être obtenu par hydrogénation et transestérification d'une huile choisie parmi l'huile de colza riche en acide érucique (usuellement désignée par l'acronyme en langue anglaise HEAR pour « High Erucic Acid Rape ») ou l'huile de moutarde, ou tout autre huile qui présente le même profil en acide gras.Preferably, 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 HEAR for " High Erucic Acid Rape ") or mustard oil, or any other oil which has the same fatty acid profile.

Par huile de colza riche en acide érucique, on entend, au sens de la présente invention, une huile de colza comprenant au moins 40 % en poids d'acide érucique (C22) par rapport au poids total..For the purposes of this invention, rapeseed oil rich in erucic acid means rapeseed oil comprising at least 40% by weight of erucic acid (C22) relative to the total weight.

A contrario, par huile de colza pauvre en acide érucique, on entend, au sens de la présente invention, une huile de colza comprenant moins de 10 % en poids d'acide érucique (C22) par rapport au poids total.. Conversely, rapeseed oil low in erucic acid, for the purposes of this invention, is understood to be rapeseed oil comprising less than 10% by weight of erucic acid (C22) relative to the total weight.

Une fois que les huiles de colza riches en acide érucique sont transformées en alcool gras, notamment par des processus d'hydrogénation et trans-estérification, on obtient une composition de cire plus diversifiée et contenant des alcools gras à longue chaine (de type C18, C20 et C22).Once rapeseed oils rich in erucic acid are transformed into fatty alcohol, notably by hydrogenation and transesterification processes, a more diverse wax composition is obtained, containing long-chain fatty alcohols (of the C18, C20 and C22 type).

De préférence, le mélange de monoglycérides et/ou de diglycérides est obtenu par saponification, hydrogénation et estérification d'une huile choisie parmi les huiles de colza riches en acide érucique, les huiles de colza pauvres en acide érucique, l'huile de moutarde, et leurs mélanges.Preferably, 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 poor in erucic acid, mustard oil, and mixtures thereof.

De manière avantageuse, la composition de cire selon l'invention peut en outre comprendre un ou plusieurs additifs présents à raison de 1 à 15 % en poids par rapport au poids total de ladite composition, ledit ou lesdits additifs étant choisis parmi les matières premières de parfum liposolubles naturelle(s) ou de synthèse, les agents répulsifs, les agents insecticides, les substances actives biocides, les agents anti-odeurs, les colorants et les stabilisateurs anti-oxydants.Advantageously, the wax composition according to the invention may further comprise one or more additives present at a rate of 1 to 15% by weight relative to the total weight of said composition, said additive(s) being chosen from natural or synthetic liposoluble perfume raw materials, repellent agents, insecticide agents, biocidal active substances, odor-neutralizing agents, colorants and antioxidant stabilizers.

Dans le cas où la composition de cire est destinée à la fabrication d'une bougie parfumée, la composition de cire selon l'invention pourra avantageusement comprendre 2 à 12% en poids par rapport au poids total de la composition de cire d'une ou plusieurs matières premières de parfum, qu'elles soient naturelles ou de synthèse.In the case where the wax composition is intended for the manufacture of a scented candle, 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 more perfume raw materials, whether natural or synthetic.

A titre d'exemples de matières premières de parfum utilisables dans la composition de cire selon l'invention, on peut notamment citer les huiles essentielles telle que l'huile essentielle de lavande ou tout concentré liposoluble de parfum usuellement utilisés dans les compositions de cire pour bougie.Examples of perfume raw materials that can be used in the composition of wax according to the invention include essential oils such as lavender essential oil or any fat-soluble perfume concentrate commonly used in candle wax compositions.

  • 20 % à 40 % en poids par rapport au poids total de la composition de cire d'un mélange d'alcool stéarylique (C18), d'alcool arachidylique (C20) et d'alcool béhénylique (C22).
According to a fourth advantageous embodiment of the present invention, the wax composition according to the invention may comprise:
  • 50% to 70% by weight relative to the total weight of the fully hydrogenated rapeseed oil wax composition, and
  • 20% to 40% by weight relative to the total weight of the wax composition of a mixture of stearyl alcohol (C18), arachidyl alcohol (C20) and behenyl alcohol (C22).

La présente invention a également pour objet une bougie végétale comprenant au moins une mèche (de préférence sensiblement droite) partiellement noyée dans la composition de cireselon l'invention.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.

Par mèche, on entend, au sens de la présente invention un élément qui alimente par capillarité la flamme en combustible. La mèche peut être en coton, en bois, en papier, ou en fibres et notamment en fibres de cellulose.For the purposes of this invention, a wick is defined as an element that feeds fuel to the flame by capillary action. The wick may be made of cotton, wood, paper, or fibers, particularly cellulose fibers.

Les bougies peuvent être des bougies contenants (c'est-à-dire que la composition de cire est coulée dans un contenant qui la supporte) ou des bougies auto-portantes sans contenant et qui ont été coulées dans des moules et sont retirées de la bougie.Candles can be container candles (i.e., the wax composition is poured into a container that supports it) or freestanding candles without a container, which have been poured into molds and are removed from the candle.

Enfin, la présente invention a encore pour objet un procédé de fabrication d'une bougie végétale selon l'invention, comprenant les étapes suivantes :

  • A) une étape de fusion des différents constituants d'une composition de cire pour bougie végétale selon l'invention, cette étape de fusion étant réalisée par chauffage à une température égale ou supérieure au point de fusion le plus élevé des constituants de ladite composition de bougie végétale (par exemple à 80°C), ladite étape de fusion conduisant à l'obtention d'une cire chaude ;
  • B) une étape optionnelle d'ajout d'un ou plusieurs additifs choisis parmi les matières premières de parfum naturelle(s) ou de synthèse, les colorants et les stabilisateurs, pour les dissoudre dans la cire chaude obtenue à l'étape A) ; et
  • C) au moins une étape de coulage de ladite cire chaude dans un contenant ou dans un moule, la ou les mèches étant intégrées dans la bougie juste avant l'étape C) de coulage, ou lors de l'étape de coulage C) ou après l'étape de coulage C).
Finally, the present invention also relates to a method for manufacturing a vegetable candle according to the invention, comprising the following steps:
  • A) a melting step of the different constituents of a vegetable candle wax composition according to the invention, this melting step being carried out by heating to a temperature equal to or greater than the highest melting point of the constituents of said vegetable candle composition (for example at 80°C), said melting step leading to the obtaining of a hot wax;
  • B) an optional step of adding one or more additives chosen from the natural or synthetic perfume raw materials, colorants and stabilizers, to dissolve them in the hot wax obtained in step A); and
  • C) at least one pouring step of said hot wax into a container or mold, the wick(s) being integrated into the candle just before pouring step C), or during pouring step C), or after pouring step C).

De manière avantageuse, l'étape A) de fusion pourra être réalisée en maintenant le mélange des différents constituants de la composition sous agitation pour favoriser un mélange homogène.Advantageously, step A) of melting can be carried out by keeping the mixture of the different constituents of the composition under agitation to promote a homogeneous mixture.

En ce qui concerne l'étape B), le coulage dans des contenants (pour les bougies contenants) ou des moules (pour les bougies auto-portantes) peut être réalisé quelle que soit la température, par exemple celle du mélange des différents constituants lors de la fusion de l'étape A ou bien à une température inférieure si la cire chaude a la fluidité nécessaire pour être coulée. En fonction de la taille du contenant ou du moule, une ou plusieurs coulées complémentaires peuvent être réalisées pour compenser la perte de volume lors de la solidification (phénomène de creusement) et avoir une surface plus plane.Regarding step B), pouring into containers (for container candles) or molds (for freestanding candles) can be done regardless of the temperature, for example, the temperature at which the different components were mixed during melting in step A, or at a lower temperature if the hot wax has sufficient fluidity for pouring. Depending on the size of the container or mold, one or more additional pours can be made to compensate for the volume loss during solidification (the phenomenon of shrinkage) and to create a flatter surface.

La présente invention peut aussi être mise en œuvre par des procédés classiques de fabrication de bougies telles que la constitution de poudre ou copeaux et leur pressage ou leur extrusion.The present invention can also be implemented by conventional candle manufacturing processes such as the formation of powder or chips and their pressing or extrusion.

Bien entendu, les différentes caractéristiques de l'invention évoquées ci- dessus peuvent être mises en œuvre les unes avec les autres selon différentes combinaisons lorsqu'elles ne sont pas incompatibles ou exclusives les unes des autres.Of course, the different features of the invention mentioned above can be implemented with each other in different combinations when they are not incompatible or mutually exclusive.

EXEMPLESEXAMPLES EXEMPLE 1EXAMPLE 1

Une bougie végétale a été réalisée conformément au procédé selon l'invention décrit précédemment à partir d'une composition de cire pour bougie comprenant 75% en poids d'une huile de colza de type alimentaire au moins partiellement hydrogénée et 25 % en poids par rapport au poids total de la composition de cire d'un mélange d'alcools gras comprenant des alcools gras à longue chaine en C18, C20 et C22 (cf. bougie 4 dans le tableau 1).A vegetable candle was produced in accordance with the process according to the invention described above from a candle wax composition comprising 75% by weight of a food-grade rapeseed oil at least partially hydrogenated and 25% by weight relative to the total weight of the wax composition of a mixture of fatty alcohols comprising long-chain fatty alcohols in C18, C20 and C22 (see candle 4 in Table 1).

A des fins comparatives, 3 bougies végétales ont été réalisées conformément au procédé de l'invention à partir uniquement d'une huile de colza de type alimentaire au moins partiellement hydrogénée (bougie 1), ainsi qu'à partir d'une composition de cire pour bougie comprenant 75% en poids d'une huile de colza de type alimentaire au moins partiellement hydrogénée et 25 % en poids par rapport au poids total de la composition de cire d'un seul alcool gras en C18 (bougie 2) ou en C22 (bougie 3).For comparative purposes, 3 vegetable candles were produced according to the process of the invention using only food-grade rapeseed oil that was at least partially hydrogenated (candle 1), and using a candle wax composition comprising 75% by weight of food-grade rapeseed oil that was at least partially hydrogenated and 25% by weight relative to the total weight of the wax composition of a single C18 fatty alcohol (candle 2) or a C22 fatty alcohol (candle 3).

Les résultats des essais sont rassemblés dans le tableau 1 ci-après, en regard de chacune des compositions de cire testées, et en complément de la figure 3.The test results are summarized in Table 1 below, next to each of the wax compositions tested, and in addition to the figure 3 .

Ces essais montrent que la texture de cire est la plus aboutie lorsqu'elle est obtenue avec un mélange ternaire d'alcool ajouté à l'huile partiellement hydrogénée. En outre ce mélange permet de moins impacter le point de fusion final et la pénétration qui reste proche de la base, ce qui n'est pas le cas avec l'alcool en C22 utilisé seul. La figure 3 montre que la texture la plus aboutie, objet de notre demande, est bien obtenue avec un mélange ternaire d'alcool ajouté à l'huile partiellement hydrogénée (bougie 4).

Furthermore, this mixture has less impact on the final melting point and penetration, which remains close to the base, unlike when C22 alcohol is used alone. figure 3 shows that the most refined texture, the subject of our request, is indeed obtained with a ternary mixture of alcohol added to partially hydrogenated oil (candle 4).
