Description
Emulsions multiples et leurs applications
L'invention se rapporte à des émulsions multiples
H/L/H, c'est-à-dire eau/huile/eau.Multiple emulsions and their applications
The invention relates to multiple emulsions
H / L / H, that is water / oil / water.
Les émulsions multiples H/L/H sont constituées par une émulsion primaire formée de microglobules aqueux dispersés au sein d'un globule huileux. Les globules huileux sont à leur tour dispersés au sein d'une phase aqueuse externe. Il s'agit donc de systèmes présentant deux interfaces, ce qui nécessite pour leur formulation deux émulsionnants : un émulsionnant lipophile qui se positionne à la première interface eau/huile entre les globules d'eau interne et la phase huileuse, et un émulsionnant hydrophile qui se place à la seconde interface huile/eau entre les globules huileux et la phase aqueuse externe. The multiple H / L / H emulsions consist of a primary emulsion formed of aqueous microglobules dispersed within an oily globule. The oily globules are in turn dispersed within an external aqueous phase. It is therefore a question of systems having two interfaces, which requires for their formulation two emulsifiers: a lipophilic emulsifier which is positioned at the first water / oil interface between the globules of internal water and the oily phase, and a hydrophilic emulsifier which is placed at the second oil / water interface between the oily globules and the external aqueous phase.
Certaines applications industrielles de telles émulsions comme en agro-alimentaire et dans le domaine cosmétique se sont heurtées au problème d'une agressivité et le cas échéant d'une toxicité de leurs émulsionnants. Certain industrial applications of such emulsions as in the food industry and in the cosmetics field have encountered the problem of aggressiveness and, where appropriate, toxicity of their emulsifiers.
Les inventeurs ont donc cherché à élaborer des émulsions de grande stabilité, avec des émulsionnants présentant une parfaite tolérance. Ce but est atteint, conformément à l'invention, en utilisant les deux types d'émulsionnants hydrophile et lipophile, mais élaborés, en tant que constituant essentiel, à partir d'un seul type de produit. The inventors have therefore sought to develop emulsions of high stability, with emulsifiers with perfect tolerance. This object is achieved, according to the invention, by using both types of hydrophilic and lipophilic emulsifiers, but elaborated as an essential constituent from a single type of product.
L'invention vise donc de nouvelles émulsions multiples élaborées avec des émulsionnants permettant leur utilisation, sans aucun effet secondaire, en cosmétologie, en pharmacie et également dans le domaine agro-alimentaire. The invention therefore aims at new multiple emulsions developed with emulsifiers allowing their use, without any side effects, in cosmetology, pharmacy and also in the agri-food field.
Ces émulsions sont caractérisées en ce qu'elles sont élaborées à partir d'émulsionnants lipophiles d'une part et d'émulsionnants hydrophiles d'autre part, ces deux émulsionnants étant essentiellement des lécithines d'origine végétale et/ou des lécithines de synthèse ou des lécithines fractionnées. Selon une disposition particulièrement préférée de l'invention les émulsions renferment exclusivement de telles lécithines comme émulsionnants lipophiles et comme émulsionnants hydrophiles. These emulsions are characterized in that they are prepared from lipophilic emulsifiers on the one hand and from hydrophilic emulsifiers on the other hand, these two emulsifiers being essentially lecithins of plant origin and / or synthetic lecithins or fractionated lecithins. According to a particularly preferred arrangement of the invention, the emulsions contain exclusively such lecithins as lipophilic emulsifiers and as hydrophilic emulsifiers.
On rappelle que les lécithines sont considérées comme constituées d'un mélange de différents phospholipides ou phosphatides. Ce terme comprend également, entre autres, les lysophospholipides, les lysolécithines, les cérébrosides, les sphingophospholipides et autres dérivés couramment utilisés dans les liposomes. On désigne également par ce terme un seul phospholipide, par exemple la phosphatidylcholine ou le phosphatidylinositol. It is recalled that the lecithins are considered to consist of a mixture of different phospholipids or phosphatides. This term also includes, inter alia, lysophospholipids, lysolecithins, cerebrosides, sphingophospholipids and other derivatives commonly used in liposomes. This term also refers to a single phospholipid, for example phosphatidylcholine or phosphatidylinositol.
Ainsi, dans la description et les revendications, on désignera par "lécithine" aussi bien des mélanges qu'un seul composé. Thus, in the description and claims, "lecithin" will be referred to as mixtures as well as a single compound.
Les lécithines lipophiles et hydrophiles utilisées, correspondent à des produits qui proviennent d'une même source ou de sources différentes, mais présentent des propriétés distinctes. Ainsi leur HLB, tel qu'évalué classiquement, est de l'ordre de 2 à 6 environ pour les émulsionnants lipophiles et supérieur à 8 environ pour les émulsionnants hydrophiles. The lipophilic and hydrophilic lecithins used, correspond to products that come from the same source or from different sources, but have distinct properties. Thus, their HLB, as conventionally evaluated, is of the order of 2 to about 6 for lipophilic emulsifiers and greater than about 8 for hydrophilic emulsifiers.
Les lécithines hydrophiles et les lécithines lipophiles des émulsions de l'invention sont avantageusement d'origine végétale, notamment de soja, colza, tournesol, avoine ou lait. The hydrophilic lecithins and the lipophilic lecithins of the emulsions of the invention are advantageously of vegetable origin, in particular of soya bean, rapeseed, sunflower, oat or milk.
Il peut s'agir encore de lécithines de synthèse ou de lécithines fractionnées, c'est-à-dire enrichies en un constituant. It may still be synthetic lecithins or fractionated lecithins, that is to say enriched in one component.
Ces lécithines peuvent être chimiquement ou enzymatiquement modifiées, par exemple hydroxylées, hydrogénées ou glycosylées. These lecithins may be chemically or enzymatically modified, for example hydroxylated, hydrogenated or glycosylated.
En variante, les émulsions de l'invention renferment, comme émulsionnants, des lécithines lipophiles et/ou hydrophiles telles que définies cidessus, mais pouvant se présenter sous forme de sels d'ammonium. Alternatively, the emulsions of the invention contain, as emulsifiers, lipophilic and / or hydrophilic lecithins as defined above, but which may be in the form of ammonium salts.
Les émulsions primaires utilisées pour l'élaboration des émulsions multiples de l'invention comportent des microglobules aqueux dispersés au sein d'un globule huileux et au moins un émulsionnant lipophile tel que défini ci-dessus. The primary emulsions used for the preparation of the multiple emulsions of the invention comprise aqueous microglobules dispersed in an oily globule and at least one lipophilic emulsifier as defined above.
Les huiles utilisées sont avantageusement des huiles végétales ou des triglycérides de chaîne moyenne notamment, des esters tels que ceux commercialisés sous la marque MygliolB, des esters simples, comme le myristate d'isopropyle ou l'oléale d'éthyle. The oils used are advantageously vegetable oils or medium chain triglycerides, especially esters such as those sold under the trade name MygliolB, simple esters, such as isopropyl myristate or ethyl oleate.
D'autres émulsions primaires renferment, en outre, au moins un électrolyte, tel qu'un sel mono- ou divalent, comme respectivement le chlorure de sodium ou le sulfate de magnésium, ou bien des sucres, comme le glucose, ou encore des acides aminés, comme le glycine ou l'alanine. Other primary emulsions contain, in addition, at least one electrolyte, such as a mono- or divalent salt, such as respectively sodium chloride or magnesium sulfate, or sugars, such as glucose, or acids. amines, such as glycine or alanine.
D'autres additifs peuvent être utilisés lors de l'élaboration de ces émulsions, comme des épaississants, tels que les gommes arabiques, l'agar-agar, le guar, les dérivés de cellulose, ou encore des substances tampons. Other additives may be used in the preparation of these emulsions, such as thickeners, such as gum arabic, agar-agar, guar, cellulose derivatives, or buffer substances.
De manière avantageuse, lesdits constituants sont présents selon les proportions suivantes, en pourcentage en poids, par rapport au poids de l'émulsion primaire,
- huile: 20 à 30% environ
- émulsionnant: de 0,5 à 4% environ de lécithine lipophile,
- le cas échéant, de 0,4% à 1% environ d'électrolyte et/ou 0,2 à 4% environ d'additif tel que défini plus haut, l'émulsion étant ajustée à 100% par addition d'eau déminéralisée.Advantageously, said constituents are present in the following proportions, in percentage by weight, relative to the weight of the primary emulsion,
- oil: about 20 to 30%
emulsifier: from approximately 0.5 to 4% of lipophilic lecithin,
where appropriate, from about 0.4% to 1% of electrolyte and / or from 0.2% to about 4% of additive as defined above, the emulsion being adjusted to 100% by addition of demineralized water .
Les émulsions multiples de l'invention renferment une émulsion primaire et un émulsionnant hydrophile tels que définis ci-dessus. The multiple emulsions of the invention contain a primary emulsion and a hydrophilic emulsifier as defined above.
Dans ces émulsions, l'émulsion primaire est présente, de manière typique, à raison de 50 à 80% en poids environ, par rapport au poids de l'émulsion multiple, et l'émulsionnant à raison de 5 à 6% en poids environ, le complément à 100% étant apporté par de l'eau déminéralisée. In these emulsions, the primary emulsion is typically present at about 50 to about 80% by weight, based on the weight of the multiple emulsion, and the emulsifier at about 5 to about 6% by weight. the 100% complement being provided by demineralised water.
Des émulsions particulièrement préférées comportent, comme émulsionnants lipophiles et comme émulsionnants hydrophiles de la lécithine de soja. Particularly preferred emulsions include, as lipophilic emulsifiers and hydrophilic emulsifiers of soy lecithin.
D'une manière avantageuse, les émulsions de l'invention sont caractérisées par une taille de globules huileux d'au moins 5 um, notamment de 5 à 10 um environ. Advantageously, the emulsions of the invention are characterized by an oily globule size of at least 5 μm, in particular from 5 to 10 μm approximately.
Ces émulsions sont obtenues selon un procédé en deux étapes. These emulsions are obtained according to a two-step process.
Dans la première étape, on prépare l'émulsion primaire en dispersant de l'eau ou une solution aqueuse dans une solution huileuse d'émulsionnant lipophile, à température ambiante et sous forte agitation. A l'aide d'un agitateur de type Rayneri, par exemple, on procède à 3000 tpm environ pendant environ 20 à 60 minutes, de préférence pendant 30 minutes. In the first step, the primary emulsion is prepared by dispersing water or an aqueous solution in an oily solution of lipophilic emulsifier, at room temperature and with vigorous stirring. With the aid of a Rayneri type stirrer, for example, the reaction is carried out at about 3000 rpm for about 20 to 60 minutes, preferably for 30 minutes.
Dans la deuxième étape, l'émulsion primaire est incorporée à température ambiante dans une solution aqueuse d'émulsionnant hydrophile sous faible agitation, jusqu'à la formation de l'émulsion multiple. L'agitation est réalisée par exemple à 400 à 1000 tpm environ lorsqu'on utilise un agitateur de type Rayneri, pendant environ 2 à 4h, notamment pendant 3 heures. In the second step, the primary emulsion is incorporated at room temperature in an aqueous solution of hydrophilic emulsifier with gentle stirring, until the formation of the multiple emulsion. The stirring is carried out for example at about 400 to 1000 rpm when using a Rayneri type stirrer, for about 2 to 4 hours, especially for 3 hours.
Ce procédé présente l'avantage d'une réalisation à température ambiante et de conduire à des émulsions de grande stabilité, avec des tailles de globules supérieures à 5 um. This process has the advantage of being carried out at room temperature and leading to high stability emulsions with cell sizes greater than 5 μm.
Compte tenu de leur innocuité, les émulsions multiples de l'invention sont utilisables pour l'élaboration de formulations cosmétiques, de formulations pharmaceutiques et également de produits alimentaires. Given their safety, the multiple emulsions of the invention can be used for the preparation of cosmetic formulations, pharmaceutical formulations and also food products.
