Abstract
Description
La présente invention concerne une émulsion notamment destinée à la fabrication de produits cosmétiques ou excipients pharmaceutiques, cette émulsion comportant une phase grasse, une phase aqueuse et un agent émulsifiant, des agents conservateurs et anti-oxydants ainsi que des additifs tels que des colorants ou des huiles essentielles. The present invention relates to an emulsion especially intended for the manufacture of cosmetic products or pharmaceutical excipients, this emulsion comprising a fatty phase, an aqueous phase and an emulsifying agent, preservatives and antioxidants as well as additives such as dyes or essential oils.
Une telle émulsion qui est de type "émulsion d'huile dans l'eau ou eau dans l'huile" est destinée notamment à la fabrication de produits cosmétiques ou à être utilisée comme excipient pharmaceutique. Such an emulsion which is of the “oil in water or water in oil emulsion” type is intended in particular for the manufacture of cosmetic products or for use as a pharmaceutical excipient.
Actuellement, pour fabriquer des émulsions cosmétiques des excipients pharmaceutiques, on fait un mélange sous agitation rapide d'une phase grasse constituée par des corps gras naturels ou synthétiques, préalablement fondus et d'une phase aqueuse chaude en présence d'un agent émulsifiant tel qu'un savon. Currently, to produce cosmetic emulsions of pharmaceutical excipients, a fatty phase consisting of natural or synthetic fatty substances, previously melted, and a hot aqueous phase in the presence of an emulsifying agent such as 'a soap.
Un tel procédé de fabrication et les produits résultants présentent un certain nombre d'inconvénients. En effet, comme il est nécessaire de chauffer les composants pour obtenir une émulsion, on détruit en partie ou en totalité certains éléments fragiles des corps naturels en réduisant ainsi l'activité du produit naturel ou en le dégradant par cette élévation de température. Or, comme ces éléments sont particulièrement intéressants par leurs effets, il serait souhaitable de les conserver dans le produit final. Such a manufacturing process and the resulting products have a number of drawbacks. Indeed, as it is necessary to heat the components to obtain an emulsion, part or all of certain fragile elements of natural bodies are destroyed, thereby reducing the activity of the natural product or degrading it by this rise in temperature. However, as these elements are particularly interesting in their effects, it would be desirable to keep them in the final product.
Les installations pour fabriquer de telles émulsions sont relativement complexes car, pour chauffer les composants, il faut des cuves à double paroi permettant la circulation du fluide calo-porteur. The installations for manufacturing such emulsions are relatively complex because, to heat the components, double-walled tanks are necessary for the circulation of the heat-carrying fluid.
Par ailleurs, on sait que les lécithines constituent des produits intéressants en cosmétique; mais qui, du fait de leurs multiples incónvénients, n'ont pas été utilisées jusqu'à ce jour dans des proportions importantes. En effet, les lécithines naturelles n'ont été utilisées comme agents émulsifiants que dans des limites très réduites, précisément à cause des inconvénients de fabrication et d'utilisation. En effet, les lécithines naturelles ont une couleur, une odeur et un toucher peu compatibles avec les critères esthétiques de la cosmétique ; elles tendent à s'oxyder, sont insolubles dans l'eau et se dégradent à la chaleur.C'est ainsi que, selon la littérature connue de l'homme de l'art, les auteurs recommandent toujours dans les formules des proportions de lécithine ne dépassant pas 5 % et de préférence comprises entre 1 et 3 en poids :G.. Walker, Amer, Perf. and Cosm. 82, 10, 73-76, 1967 Cosm perf. 89,7, 31-35, 1974 ; N. Herb, Cosm. Perf. 90,1, 39-42, 1975 ; S.B. Curri, Cosm. Toiletries, 92, 12, 19-20, 1977 GS Kass, Cosm. Toiletries 94,8, 25-30, 1979). Furthermore, we know that lecithins are interesting products in cosmetics; but which, due to their multiple drawbacks, have not been used to date in significant proportions. In fact, natural lecithins have only been used as emulsifying agents within very limited limits, precisely because of the drawbacks of manufacture and use. Indeed, natural lecithins have a color, an odor and a touch that are hardly compatible with the aesthetic criteria of cosmetics; they tend to oxidize, are insoluble in water and degrade on heat. Thus, according to the literature known to those skilled in the art, the authors always recommend in the formulas proportions of lecithin not exceeding 5% and preferably between 1 and 3 by weight: G. Walker, Amer, Perf. and Cosm. 82, 10, 73-76, 1967 Cosm perf. 89.7, 31-35, 1974; N. Herb, Cosm. Perf. 90.1, 39-42, 1975; S.B. Curri, Cosm. Toiletries, 92, 12, 19-20, 1977 GS Kass, Cosm. Toiletries 94,8, 25-30, 1979).
La présente invention a pour but de créer une émulsion formée uniquement de produits naturels, qui puisse se fabriquer à froid sans élévation de température susceptible de détruire, même par une légère élévation de température audelà de la température ambiante, certaines caractéristiquesu des constituants de l'émulsion, ne contenant que des composants naturels, ainsi qu'une forte proportion de lécithines. The object of the present invention is to create an emulsion formed solely from natural products, which can be produced cold without an increase in temperature capable of destroying, even by a slight increase in temperature beyond room temperature, certain characteristics or constituents of the emulsion, containing only natural components, as well as a high proportion of lecithins.
A cet effet, l'invention concerne un procédé de fabrication d'une émulsion comportant une phase grasse et une phase aqueuse, un agent émulsifiant ainsi que des agents conservateurs et anti-oxydants et, le cas échéant, des colorants et des huiles essentielles, tous ces produits étant naturels et à l'état liquide, semi-solide, soluble ou dissoluble dans l'eau ou dans les matières grasses liquides, à la température ambiante, ce procédé étant caractérisé en ce qu'on ajoute un émulsifiant constitué par la combinaison de lécithines et de saponines et on agite les composants sans élévation de tempéra- ture, à la température ambiante pour former ;L'émulsion. To this end, the invention relates to a process for the manufacture of an emulsion comprising a fatty phase and an aqueous phase, an emulsifying agent as well as preserving and antioxidant agents and, where appropriate, dyes and essential oils, all these products being natural and in the liquid, semi-solid, soluble or dissoluble state in water or in liquid fats, at ambient temperature, this process being characterized in that an emulsifier consisting of combination of lecithins and saponins and the components are stirred without temperature rise, at room temperature to form the emulsion.
L'invention concerne également des émulsions notamment destinées à la fabrication de produits cosmétiques ou d'excipients pharmaceutiques, comportant une phase grasse et une phase aqueuse, un agent émulsifiant, des agents conservateurs et anti-oxydants ainsi que des additifs tels que des colorants ou des huiles essentielles, celle émulsion étant caractérisée en ce que tous les composants sont des substances naturelles d'origine végétale ou animale et l'agent émulsifiant est formé par la combinaison de saponines et de lécithines les lécithines faisant partie à la fois de l'agent émulsifiant et de la phase grasse, la phase aqueuse étant constituée par un gel des gommes et de colloïdes
Selon l'invention, on a constaté de façon surprenante qu'en utilisant un émulsifiant constitué par la combinaison de lécithines et de saponines, il était possible de disperser et de solubiliser des proportions élevées de léclth,nes dans l'eau On peut ainsi adapter la proportion respective des saponines et des lécithines pour former une gamme d'agents émulsifiants permettant d'obtenir par une agitation à froid toutes les formes d'émulsion nécessaires telles que huile dans eau, eau dans huile, des crèmes, des pattes, des cnguents, des gels, des laits, des lotions, etc... pour des usages cosmétiques ou comme excipients pharmaceutiques.The invention also relates to emulsions especially intended for the manufacture of cosmetic products or pharmaceutical excipients, comprising a fatty phase and an aqueous phase, an emulsifying agent, preservatives and antioxidants as well as additives such as dyes or essential oils, that emulsion being characterized in that all of the components are natural substances of plant or animal origin and the emulsifying agent is formed by the combination of saponins and lecithins, the lecithins being both part of the agent emulsifier and fatty phase, the aqueous phase consisting of a gel of gums and colloids
According to the invention, it has surprisingly been found that by using an emulsifier constituted by the combination of lecithins and saponins, it was possible to disperse and dissolve high proportions of leclth, nes in water. It is thus possible to adapt the respective proportion of saponins and lecithins to form a range of emulsifying agents making it possible to obtain, by cold stirring, all the necessary forms of emulsion such as oil in water, water in oil, creams, legs, ointments , gels, milks, lotions, etc ... for cosmetic uses or as pharmaceutical excipients.
La combinaison constituant l'émulsifiant permet non seulement d'intégrer à l'émulsion une quantité importante de lécitnes faisant à la fois partie de l'émulsifiant et de la phase grasse, ce qui est intéressant pour les propriétés de I"émulsion, mals également de conserver ces lécithines sans que niapparaissent les inconvénients de celles-ci, tels que l'odeir et le toucher, la tendance à l'oxydation, et l'insolu bilié dans l'eau ou la dégradation à la chaleur.En effet, et ccntralrement à ce qui est possible, sans utiliser le complexe émulsifiant lécithines saponines, les lécithines sont très peu utilisables dans des émulsions alors que, dans les produits selon l'invention, ce pourcentage peut être accru de façon considérable sans que n'apparaissent les inconvénients propres des lécithines
De plus, comme le complexe émulsifiant permet de faire uné émulsion à froid par simple agitation et non par chauffage préalable des composants pâteux ou solides ou mêmes liquides pour arriver à une émulsion, on réduit, d'une part, le ccut des installations de fabrication de ces produits car, au lieu d'utiliser des cuves à double paroi avec circuit de chauffe, on peut se limiter à des cuves simples munies d'un agitateur et, d'autre part, on réduit le coût du procédé en économisant l'énergie de chauffage.The combination constituting the emulsifier makes it possible not only to integrate into the emulsion a large quantity of lecitnes forming both part of the emulsifier and of the fatty phase, which is advantageous for the properties of the emulsion, which is also bad. to keep these lecithins without their drawbacks appearing, such as odor and touch, the tendency to oxidation, and the insoluble bile in water or degradation by heat. ccntralement to what is possible, without using the emulsifier complex lecithins saponins, lecithins are very little usable in emulsions whereas, in the products according to the invention, this percentage can be increased considerably without appearing the disadvantages clean lecithins
In addition, as the emulsifying complex makes it possible to make a cold emulsion by simple stirring and not by prior heating of the pasty or solid or even liquid components to arrive at an emulsion, the ccut of the manufacturing installations is reduced on the one hand of these products because, instead of using double-walled tanks with heating circuit, we can limit ourselves to simple tanks provided with an agitator and, on the other hand, we reduce the cost of the process by saving the heating energy.
En outre, comme le produit est fabriqué sans subir de traitement thermique, il conserve son intégrité, ce qui est particulièrement important dans le cas de produits dont tous les composants sont naturels Cela est d'autant plus important que les lécithines se dégraderaient à des températures supérieures à 70 C De plus, de façon importante, on évite la formation de peroxydes organiques qui sont des composés de réaction fortement irritants pour la peau et les muqueuses
Enfin, des essais ont montré que l'on pouvait atteindre '3usqu'à des teneurs en lécithines dans des proportions allant jusqu'à 20 % en poids de la composition de l'emul- sion.-
Selon 11 invention
a) la phase grasse de l'émulsion peut être constituée par des graisses végétales telles que des huiles végétales et notamment des huiles de germes de céréales, d'avocat, d"amande, de noyaux, de sésame, de tournesol, d'olive, de soja, jojoba, de sasafra, de ricin, de raisins, etc.. ou des huiles animales telles que des huiles de poisson, de la lanoline liquide, de l'huile de vison etc... On utilisera en particulier des huiles d'avocat, de sésame, de ricin et de carthame.In addition, as the product is produced without undergoing heat treatment, it retains its integrity, which is particularly important in the case of products of which all the components are natural. This is all the more important as the lecithins degrade at temperatures. higher than 70 C In addition, importantly, the formation of organic peroxides is avoided which are reaction compounds which are highly irritating to the skin and the mucous membranes.
Finally, tests have shown that it is possible to reach 3 levels of lecithins in proportions of up to 20% by weight of the composition of the emulsion.
According to 11 invention
a) the fatty phase of the emulsion can consist of vegetable fats such as vegetable oils and in particular oils of germs of cereals, avocado, almond, kernels, sesame, sunflower, olive , soy, jojoba, sasafra, castor, grapes, etc ... or animal oils such as fish oils, liquid lanolin, mink oil etc ... Oils will be used in particular avocado, sesame, castor oil and safflower.
b) L'agent émulsifiant est constitué par la combinaison de lécithines et de saponines. On peut utiliser un mélange de lécithines tel que des lécithines de moelle, d'oeuf (ovilécithines) ou de soja (végilécithines). On utilise de préférence, des lécithines de soja. Pour les saponines, on peut utilise des combinaisons de saponines par exemple extraites de marron d'inde, de saponaire (gypsogénine), de
Panama (acide quillajique) de de sapindus (hédéragénol).b) The emulsifying agent consists of the combination of lecithins and saponins. A mixture of lecithins such as marrow lecithins, egg lecithins (ovilecithins) or soya (vegilecithins) can be used. Preferably, soy lecithins are used. For saponins, combinations of saponins can be used, for example extracted from horse chestnut, saponary (gypsogenin),
Panama (quillajic acid) of sapindus (hederagenol).
c) La phase aqueuse est nécessairement constituée par une solution ou un gel de gommes naturelles qui modifient à faible dose les caractéristiques rhéologiques de l'émulsion qui sont utilisées à la fois comme colloïdes protecteurs et stabilisateurs de l'émulsion et comme agents épaississants ou gélifiants. En effet, la phase grasse étant constituée par des lipides liquides ou semi-liquides à la température ambiante qui donnent des émulsions liquides, il est nécessaire, de régler la viscosité par des agents épaississants,
Comme gomme, on envisage la gomme adragante, les alginates, les carraghénates, les pectines, les celluloses de fruits ou de légumes, l'amidon, les galactommananes.De façon préférentielle on utilise des gommes à pouvoir viscogène élevé et plus parti culièrement les carraghénates et les gommes de guar, de caroube et de tara, des semences de coings.c) The aqueous phase is necessarily constituted by a solution or a gel of natural gums which modify at low dose the rheological characteristics of the emulsion which are used both as protective colloids and stabilizers of the emulsion and as thickening or gelling agents . Indeed, the fatty phase being constituted by liquid or semi-liquid lipids at room temperature which give liquid emulsions, it is necessary to regulate the viscosity by thickening agents,
As gum, we consider gum tragacanth, alginates, carrageenans, pectins, fruit or vegetable celluloses, starch, galactommananes. Preferably gums with high viscogenic power and more particularly carrageenans are used. and guar, carob and tara gum, quince seeds.
La combinaison de lécithines et de saponines formant l'émulsifiant représente entre 3 % et 25 % du poids de la composition totale On choisit de préférence une teneur comprise entre 5-et 15 %. Dans cette combinaison, les saponines représentent entre 1 et 20 % du poids des lécithines et, de préférence, entre 2 et 10 %0
L'agent de stabilisation qui règle la viscosite et la stabilité de l'émulsion représente entre 0,1 et 5 % du poids de la composition et, de préférence, de 1 à 3 %.The combination of lecithins and saponins forming the emulsifier represents between 3% and 25% of the weight of the total composition. A content preferably between 5 and 15% is chosen. In this combination, the saponins represent between 1 and 20% of the weight of the lecithins and, preferably, between 2 and 10% 0
The stabilizing agent which regulates the viscosity and the stability of the emulsion represents between 0.1 and 5% of the weight of the composition and, preferably, from 1 to 3%.
Les émulsions ainsi fabriquées, selon l'invention, peuvent également recevoir des additifs tels que des agents anti-solaires, des vitamines, des colorants végétaux, des liquides biologiques, des extraits végétaux ou des agents anti- rides, etc
La présente invention sera illustrée à l'aide de quelques exemples de mise en oeuvre.The emulsions thus produced, according to the invention, can also receive additives such as sunscreen agents, vitamins, vegetable dyes, biological liquids, plant extracts or anti-wrinkle agents, etc.
The present invention will be illustrated with the aid of a few examples of implementation.
