Definitions
- the invention relates to systems for the encapsulation of substances of interest and their applications.
- microencapsulation brings together all of the technologies that allow the preparation of individualized microbeads made of a coating material containing an active material.
- the microbeads also called microparticles, have a size of between 1 ⁇ m and several mm and typically contain between 5 and 90% (by weight) of active material.
- the active ingredients are of very varied origin: active pharmaceutical ingredients, cosmetic active ingredients, food additives, phytosanitary products, scented essences, microorganisms, cells or even catalysts for chemical reactions.
- the coating materials are polymers of natural or synthetic origin, hydrophobic or hydrophilic, or lipids.
- Microbeads prepared from hydrophobic polymeric materials are generally prepared by phase separation techniques (coacervation or extraction-evaporation of solvent) or by polymerization or polycondensation.
- Phase separation techniques generally use organic solvents which have a certain number of drawbacks: elimination in the atmosphere, persistence in galenical systems, denaturation of certain microencapsulated molecules.
- the methods by polymerization or polycondensation if they have the advantage of not using a solvent, have the disadvantage of using very reactive materials capable of reacting with the substances encapsulated within the microbeads.
- the most of the materials making up these raw materials are synthetic substances whose harmfulness to the environment or the organism is not always known.
- Microbeads formed from hydrophilic polymeric materials are generally prepared by gelation or coacervation techniques. This technique which makes it possible to encapsulate molecules in liquid or solid form is based on the desolvation of macromolecules leading to phase separation within a solution.
- a complex coacervation is carried out in which the desolvation is carried out on two polymers. It can be carried out, for example, by adjusting the pH of the solution containing the polymers so that the positive charges of the first polymer balance the negative charges of the second, forming a precipitation and a coating of the materials to be encapsulated.
- the gelled membrane is then crosslinked with glutaraldehyde. This technique is mainly intended for lipophilic materials (vegetable or mineral oils, essential oils).
- the microbeads can be prepared by ionic gelation. In this case, a solution of sodium alginate or pectinate is injected
- microencapsulation is carried out by thermal gelation. This process called "hot melt” is based on the melting of the coating material.
- the active material to be encapsulated is dissolved or dispersed in this molten material.
- the whole is emulsified in a dispersing phase the temperature of which is maintained above the melting temperature of the coating.
- the solidification of the dispersed globules is obtained by brutally cooling the medium.
- microencapsulation there are the soft phases (micelles, liposomes, spherulites, microemulsions, emulsions %) and molecular encapsulation (cyclodextrins).
- the invention therefore aims to provide new systems for microencapsulation with great storage stability, in particular having a high sensitivity to shear, which makes it possible to easily release their content.
- the invention also relates to the applications of these systems, in particular in therapy, in cosmetics and in the food sector.
- microencapsulation systems of the invention are characterized in that they are produced from oily substances and sugars, and form an essentially organized whole.
- This organization corresponds more particularly to stacks of crystal structures.
- Systems of this type present, for example, an organization in crystal structures of the hexagonal or pseudo-hexagonal type.
- the term "sugar”, as used in the description and the claims, designates poly- and / or oligosaccharides, and / or starches, and / or their derivatives.
- said sugars are oligosaccharides and, in particular, cyclodextrins and their derivatives.
- Cyclodextrin ⁇ is particularly advantageous in view of its ability to form inclusion complexes with oily substances.
- said sugars are polysaccharides, such as starch.
- the different sugars and oily substances above correspond to natural or synthetic molecules.
- oily substances used in the composition of the systems of the invention are liquid or semi-solid and are capable of forming the oily phase of an emulsion. Mention will more particularly be made of oils or their components. These include fatty acids, mono-, di- or tri-glycerides.
- Suitable oils include vegetable oils, such as soybean, wheat germ, avocado or sweet almond oil, or animal oils, such as evening primrose oil, synthetic or mineral oils, such as paraffin oil.
- the oily substances may be in the dispersed state and / or in the form inclusion complexes, for example with cyclodextrins and, in particular, ⁇ cyclodextrin.
- Substances of interest can be trapped in said oily substances.
- the invention therefore relates to systems containing, in addition, one or more substances of interest chosen from substances which do not affect the organization of the assembly and its stability.
- These substances of interest are water-soluble substances or liposoluble substances.
- the invention advantageously makes it possible to formulate fragile molecules, sensitive to oxidation or to light, or which can be denatured by conventional encapsulation methods, which use organic solvents, and / or surfactants, including total extraction is difficult, if not impossible, at a high temperature, or even at excessive shear.
- the systems of the invention are in particular in the form of solid beads with a solid structure.
- Such beads have, in general, a particle size of the micron to several centimeters, in particular from 0.1 to 8 mm, or also from 0.1 to 5 mm, in particular from 0.5 to 3 mm.
- the systems are in the form of compact or fluid phases. These various systems can also be dried, lyophilized, suspended in an aqueous or non-aqueous, liquid or gelled medium.
- the systems of the invention can be introduced into capsules.
- the invention also relates to a process for preparing the systems defined above.
- the stirring is carried out under conditions of speed and duration making it possible to obtain solid beads of full structure, the latter being recovered, washed and optionally dried or lyophilized.
- the stirring is stopped before the formation of these beads, and the intermediate phases are recovered, more especially the compact phase defined above.
- this process does not require the use of organic solvents, nor a heating step, nor a significant consumption of energy, which constitutes an advance of great interest in the field of encapsulation.
- this method of manufacturing the balls does not require special equipment for manufacturing, such as turbines, homogenizers, specific hoods.
- the agitation required to form the beads consumes very little energy.
- the manufacturing process does not involve organic solvents or surfactants, which represents an advantage in terms of safety.
- the materials used for the formation of beads and intermediate phases are non-toxic and biodegradable (oily substances, sugars). It is possible to form beads with these sugars, in particular poly and oligosaccharides, and in particular cyclodextrins without crosslinking. The materials used are readily available on the market and at moderate cost.
- the invention thus provides means of great simplicity and low cost for manufacturing new systems usable in many sectors of industry.
- the invention relates in particular to their application in therapy where they make it possible in particular to encapsulate active principles of medicaments and constitute new galenical forms or any intermediate form which can be used in the production of other forms of administration (capsules, granules, compacts. ..) for oral administration.
- the active ingredients encapsulated according to the invention can also be administered via the skin and on the mucous membranes.
- the invention also relates in particular to their application in cosmetics for . 1 encapsulation of active substances in cosmetology and / or pigments and / or dyes and / or natural or synthetic products used in the composition of perfumes, aromas, fragrances.
- the use of the systems thus makes it possible to produce new formulations, usable, for example, as make-up products. Forms and presentations such as compacts, ball sticks, fluid ball gels, bath beads or the like can thus be produced.
- FIGS. 1 to 5 represent, respectively,
- Figures la to le photos in scanning electron microscopy on whole beads before lyophilization (figure la), lyophilized (figure 1b): (Gx30) and on their surface (Gx625) (Figure le);
- FIGS. 2a and 2b photos in transmission electron microscopy of a cryofracture of beads (Gx30000) (FIG. 2a); the zoomed part (Gx78000) ( Figure 2b);
- Figures 3a to 3c a photo of crystals observed by optical microscopy (Gx ⁇ 50) ( Figure 3a); a photo in confocal optical microscopy of semi-fine sections of beads marked with Red Nil included in resin, image in transmission (Gx64) (figure 3b), and a photo in scanning electron microscopy of crystals after extraction with isopentane (Gx4000 ) ( Figure 3c).
- Example 1 formation of beads from cyclodextrin ⁇ and vegetable oils.
- cyclodextrin ( ⁇ -CD) (3 to 6% m / m) is dissolved or not dissolved in an aqueous phase representing 67 to 82% of the total mass.
- An oily phase formed from soybean oil (15 to 30% m / m) is added to the surface of the water.
- the pH of the aqueous phase can be adjusted from pH 2 to 9.3.
- the molecule to be encapsulated can be added in one of two phases: a water-soluble molecule can be added to the aqueous phase and a liposoluble molecule can be added to the oily phase.
- the flask is then closed, then stirred (ROTATEST, Bioblock Scientific) at a speed of 200 revolutions / minute, in a thermostatted water bath (28 ° C). After about 0.5 to 30 days, but more generally 2 to 3 days, more or less spherical white beads are formed.
- Several intermediate states (fluid, then compact states) precede the formation of the balls.
- the kinetics of ball formation, under the conditions tested, is slower at acidic pH. At pH 9.5 to 10.3, the phases remain compact.
- the beads obtained are stable (for at least 3 years) and suspended in a dispersing phase, the turbidity of which varies. Indeed, the beads prepared under the above conditions have a homogeneous size distribution and are found in a clear dispersing phase. The beads, which have a more heterogeneous size distribution, end up in a whitish phase.
- the beads in suspension in water, dried or lyophilized can be dispersed in hydrogels, for example Carbomer, cellulose or 407 poloxamer.
- the beads are capable of undergoing other operations such as normal pressure filtration, low speed centrifugation, drying in an oven (the beads then become transparent).
- the internal structure of the beads was also studied. To this end, the beads suspended in water underwent cryofracture and the replicas were observed by transmission electron microscopy. As shown in Figures 2a and 2b, the beads have a matrix structure, that is to say full, having globular structures and regular, angular elements of about 30 nm.
- the beads consist of lipophilic compartments
- the images obtained by confocal microscopy show a distribution of calcein (hydrophilic fluorescent marker) on the surface of the beads and a sporadic distribution of Nile Red (marker fluorescent lipids) on and inside the lipids.
- the microscopic analysis of the suspension media of the beads does not show any significant presence of oil droplets, showing that the oil is well trapped in the system.
- the following table reports the diameter of the beads obtained and the formation time.
- Example 4 Formation of the beads after pre-emulsification of the aqueous phase with the oily phase
- Example 1 The procedure is as described in Example 1, but the aqueous phase containing the cyclodextrin ( ⁇ ) is emulsified with the oily phase using a stirring turbine. The mixture obtained is then subjected to the stirring conditions described in Example 1.
