FIELD OF THE INVENTION
The invention relates generally to beverage compositions comprising cryogenically produced cannabinoid nanoparticles using cannabinoids made from hemp, and processes for making the same.
BACKGROUND
Producing nanoparticles made from chemical and biological compounds can pose engineering challenges depending on the compounds chosen and the characteristics of the particles being sought. Producing nanoparticles directly from the compounds themselves is a different challenge than adhering or encapsulating an active compound within a nano-scale carrier particle such as liposomes, micelles, shells, or even conjugating to nano-scale carrier compounds, nano-scale metal powders, nano-scale polymers, or nano-scale biologics such as proteins, amino acids, various organic sugars, or organic salts.
Some of the engineering challenges relate to the nanoparticle compounds include solubility, charge, purity, temperature, crystallization, stereochemistry, and stability. Other engineering challenges relate to the nanoparticle aspect and include the process for making the nanoparticles, characterizing the nanoparticles, analyzing nanoparticle size and size distribution, analyzing nanoparticle density, solubility, surface charge, surface chemistry and morphology, surface adhesion, purity, temperature, and stability.
Technologies for making nanoparticles can include grinding, milling, atomization, spray drying, homogenization, sonication, use of solvents, centrifugation, filtering, and lyophilization. As the desired size of the particles shrinks from micrometer to nanometer scale, the selection of process parameters and techniques become more critical and the processes more difficult.
Cannabis has more than 400 bioactive components, the majority of which are cannabinoids or phytocannabinoids, polyphenols, flavonoids, terpenes, terpenoids, fatty acids, oils and waxes. Cannabinoids which are useful for commercial and therapeutic uses are tetrahydrocannabinol, cannabidiol, cannabinol as well as their carboxylic acid derivatives and cannabis-derived terpenes.
However, cannabinoids are known for the processing and handling difficulty they present, especially when attempting to produce cannabinoids that can be used in commercial or therapeutic applications. Additionally, much of the cannabis industry generates cannabinoid products that do not have pure ingredients, have toxic impurities, do not contain what the label says they contain, and are not safely produced using Current Good Manufacturing Practice (CGMP) regulations enforced by the FDA, and as such suffer from the lack of oversight, purity, and reproducibility.
Accordingly, a need exists for beverage compositions comprising cryogenically produced cannabinoid nanoparticles using cannabinoids made from hemp, and processes for making the same to solve these and other problems in the art.

Examples of cannabinoids include: tetrahydrocannabinolic acid (THCA), tetrahydrocannabinol (THC), delta-8-tetrahydrocannabinol (delta-9-THC), delta-8-tetrahydrocannabinol (delta-8-THC), cannabidiolic acid 9CBDA), cannabidiol (CBD), tetrahydrocannabivarin (THCV), cannabigerolic acid (CBGA), cannabigerol (CBG), cannabinolic acid (CBNA), cannabino (CBN)l, cannbichromenic acid (CBCA), cannabichromene (CBC), cannabicyclolic acid (CBLA), and cannabicyclol (CBL).
The term “Cannabis” refers to a plant that belongs to a family (Cannabaceae) with a single genus (Cannabis) with only one species (sativa) that has many varieties. The plant is very rich in constituents, the most specific of which are the cannabinoids that have not been reported in any other plants and it has a broad pharmacological properties with tremendous medical potential in the treatment of epilepsy, spasticity, inflammation, irritable bowel syndrome, pain and other disorders. Methods for growing, harvesting, processing, formulation, and use continue to evolve towards an important position in the pharmacopeia. Cannabis (hemp) belongs together with the genus Humulus (hop) to the family of Cannabaceae, wherein however Humulus does not contain cannabinoids. Within the genus Cannabis there is a botanical distinction made, more specifically in the Cannabis species Cannabis sativa Linnaeus, Cannabis indica LAM, and Cannabis ruderalis or in the “species complex” Cannabis sativa L., consisting of the Cannabis sativa sub-groups ssp. sativa and ssp. indica. In addition, cannabis can be distinguished into a drug hemp and fiber hemp, wherein the distinction is made on the basis of the ratio of the primary cannabinoids which are cannabidiol (CBD) and Δ9-tetrahydrocannabinol (Δ9-THC or delta 9 THC). Hemp which is dried and extracted for this purpose may have at most a Δ9-THC content of 0.3% on a dry weight basis, Cannabis sativa L. contains more than 400 different ingredients, including more than 60 compounds from the class of cannabinoids. Hemp is a strain of the Cannabis sativa plant that is grown specifically for the extraction of cannabinoids. Additionally, another form of Cannabis plant, wherein the plant may be Cannabis Sativa or Cannabis Indica, may be present and extracted from marijuana and thus contain a higher amount of THC or Δ9-tetrahydrocannabinol while containing other cannabinoids such as CBD and other forms of cannabinoids.

As used herein, the temperature used in the centrifugal distillation process may range and include 50 to 350 degrees Celsius, and preferably 75 to 250 degrees Celsius, and more preferably 100 to 200 degrees Celsius.
The term “dosage form”, as used herein, refers in a non-limiting sense to cannabinoid nanoparticle beverage formulations that include gels, powders, suspensions, emulsions, concentrates, slurries, and liposomal and encapsulated forms.
The term “encapsulation”, as used herein, refers in a non-limiting sense to a process or mechanism used to provide a protective shell or a membrane barrier or a coating or a substance that contains another substance or a composition that wraps around another composition or other meaning that extends to the current definition of encapsulation in its broadest meaning or interpretation. Nano-encapsulation is the process of encapsulating a substance with various coating materials at the nanoscale range from 50 to 1000 nm in size and preferably from 100 to 500 nm in size. As a result, the cannabinoid or mixture of cannabinoids may be nano-encapsulated to produce a particle size in the nanoscale range of 50 to 1000 nm in size and preferably from 100 to 500 nm.
The terms “extract” or “extraction”, as used herein, refer in a non-limiting sense to a process for obtaining raw Cannabinoid extract from dried Hemp plant material. Non-limiting illustrative processes include supercritical CO2 extraction, liquid chromatography, solvent extraction, distillation extraction, and olive oil extraction. Extracts contain other plant components—major and minor cannabinoids, terpenes, and flavonoids—that isolates do not. The distillation method uses alcohols, such as ethanol, to extract the cannabinoids from the marijuana or hemp plant. The extract that results from this distillation can be referred to as cannabinoid-containing extract or THC, or THC oil, or THC Distillate or CBD or CBD oil or CBD Distillate or any of the cannabinoids listed above. In another method, hydrocarbon extraction using hydrocarbon solvents such as butane, pentane, propane, hexane, or heptane has also been used to extract cannabinoids from the dried marijuana or hemp. Yet in another method lipid extraction such as coconut oil can be used to extract cannabinoids from the marijuana or hemp.
The term “hemp” does not include marijuana. “Natural hemp”, “industrial hemp”, or “hemp” as used herein refers to a variety of Cannabis sativa that is federally compliant with the Farm Bill and contains less than 0.3% Delta-9-tetrahydrocannabinol (THC). Important commercial benefits include that industrial hemp cultivars grow approximately twice a fast as marijuana, processes that extract CBD from industrial hemp obtain a cleaner CBD that can be directly chemically converted in one-step to valuable cannabinoids, and the cost for industrial hemp products is about one tenth of the cost of marijuana originated products.
The term “isolate”, as used herein, refers in a non-limiting sense to a cannabinoid crystalline powder. An example is CBD Isolate, which is one of the purest form of cannabidiol, and unlike the oil, Isolates contain no THC or practically no other plant impurities. CBD Isolate may be 99% pure cannabidiol or even higher purity depending on the extraction procedure. Furthermore, the cannabinoid or cannabinoid mixture may contain other cannabis compounds such as flavonoids and terpenes.
The term “Kief”, as used herein, refers in a non-limiting sense to a high potency THC composition consisting of accumulated trichomes, or resin glands, sifted from cannabis flowers through a mesh screen or sieve. Trichomes are the crystal-like hairs that cover the cannabis flower bud. Trichomes secrete a sticky resin containing the terpenes and cannabinoids that give cannabis its unique qualities. As concentrated resin glands, kief occurs as a fine powder and is a potent form of cannabis. More simply, Kief is a cannabis concentrate that contains from about 50%-80% THC and includes both cannabinoids and terpenes.
The term “liposome” as used herein refers to self-assembled (phospho)lipid-based drug vesicles that form a bilayer (uni-lamellar) and/or a concentric series of multiple bilayers (multilamellar) enclosing a central aqueous compartment. The size of liposomes ranges from 30 nm to 1000 nm scale, with the phospholipidbilayer being 4-5 nm thick. Liposomes herein are used as a delivery vehicle for the cannabinoid nanoparticles, nanoparticle suspensions, or nanoparticle emulsions. Liposomes may be administered via parenteral, pulmonary, oral, transdermal, ophthalmic, and nasal routes. Commercially approved liposomes have a composition made from two to five of the following ingredients: fully hydrogenated soy phosphatidylcholine (HSPC), egg phosphatidylcholine (EPC), distearoylphosphatidylcholine (DSPC), dioleoyl phosphatidylcholine (DOPC), dierucoyl phosphatidylcholine (DEPC), palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC), dipalmitoyl phosphatidylcholine (DPPC), dimyristoylphosphatidylcholine (DMPC), dipalmitoylphosphatidylglycerol (DPPG), distearoylphosphatidylglycerol (DSPG), dioleoyl phosphatidylserine (DOPS), dioleoylphosphatidylserine (OOPS), cholesterol (Chol), sphingomyelin (SM), N-(carbonyl-methoxypolyethlyeneglycol-2000)-distearolyphosphatidylethanolamine (MPEG-2000-DSPE). Manufacturing processes for liposomes include the thin-film hydration method, the ethanol injection method, and the double emulsion method. The processes for preparing drug (cannabinoid nanoparticle) loaded liposomes include (1) the preparation of MHLVs or ULVs depending on the choice of methods; (2) size reduction if necessary; (3) preparation of the drug solution(s) and drug loading, while this step is combined with step 1 in the case of passive drug loading; (4) buffer exchange and concentration if necessary; (5) sterile filtration or aseptic processing; (6) lyophilization, if needed, and packaging.
The term “lyophilized sphere or particle”, as used herein, refers in a non-limiting sense to a cannabinoid distillate formulated as a nanoparticle having a diameter of about 50 to 1000 nanometers and preferably 100 to 500 nm and having a shell comprising a biodegradable polymer containing a cannabinoid or mixture of cannabinoids. As used herein, the term “sphere” is not intended to suggest uniformity in shape, or geometric form. The spheres may have irregularities and be particle-like. The terms sphere and particle are used interchangeably. The term shell is used to denote the outer surface of the sphere or particle.
The term “molecular sieve”, as used herein, refers in a non-limiting sense to a material with pores of uniform size. These pore diameters are similar in size to small molecules, and thus large molecules cannot enter or be adsorbed, while smaller molecules can. As a mixture of molecules migrates through the stationary bed of porous, semi-solid substance referred to as a sieve (or matrix), the components of the highest molecular weight (which are unable to pass into the molecular pores) leave the bed first, followed by successively smaller molecules. Some molecular sieves are used in size-exclusion chromatography, a separation technique that sorts molecules based on their size. Another important use is as a desiccant. Molecular sieves contemplated herein include aluminosilicate zeolites, Si/Al with molar ratio less than 2, sodium aluminosilicate as specifically approved by the U.S. FDA for use with consumable products under 21 CFR 182.2727, zeolites, activated charcoal, silica gel/silicon dioxide for 20-50 nm, macroporous silica for 20-100 nm, porous glass, and compositions providing the same or similar function, the same or similar way, with the same or similar results.
The pore diameter of a molecular sieve is measured in ångströms (Å) or nanometres (nm). According to IUPAC notation, microporous materials have pore diameters of less than 2 nm (20 Å) and macroporous materials have pore diameters of greater than 50 nm (500 Å); the mesoporous category thus lies in the middle with pore diameters between 2 and 50 nm (20-500 Å).
The term “nanoparticle”, as used herein, refers in a non-limiting sense to a small particle that ranges on average between 50 to 1000 nm in size, wherein the majority of the particles are made up of such a wide range of size in its composition. Some of these nanoparticles may be independent in size and some may be aggregated or agglomerated or attached into a much larger particle that can later be redistributed upon mixing or shaking or simply dissociated over time. Some nanoparticles could be made up of only a few hundred atoms and have much smaller sizes and still be considered to be nanoparticles in this invention, however, a substantial amount of the nanoparticle will be in the preferred size ranges of 50 to 100 nm, 50 to 250 nm, 50 to 500 nm, 100 to 250 nm, 100 to 500 nm, and 250 to 500 nm.
The term “nanosuspension”, as used herein, refers in a non-limiting sense to the process or mechanism in which nanoparticles of a substance are dispersed but not totally dissolved in a fluid. A nanosuspension is defined as a heterogeneous mixture in which the solid nanoparticles are spread throughout the liquid without dissolving in it or without dissolving entirely in it. A nano-suspension is a submicron colloidal dispersion of discrete nanoparticles, which are dispersed throughout the solution. Cannabinoid nano-suspension could be a dispersion of cannabinoid nanoparticles which are dispersed throughout the solution. Nano-suspensions offer a means of administering increased concentration of poorly soluble drugs or substances and possibly enhancing the bioavailability of the formulation when consumed or ingested in mammals and preferably in humans. Nano-suspensions of cannabinoid nanoparticles or mixture of cannabinoid nanoparticles as beverages are applied to delivering said cannabinoid composition via oral delivery routes.
The term “nanoencapsulation” as used herein refers in a non-limiting sense to a method to produce nano-encapsulated substance having a shell of insoluble, infusible, high molecular weight condensation polymer. The nano-encapsulating process of cannabinoid nanoparticles comprises division and dispersion of the substance to be encapsulated as a discontinuous phase, within a continuous fluid phase. Each phase must contain an intermediate or an intermediate must be added, which will react with the intermediate in the other phase to form a continuous high molecular weight condensation polymer film at the interface of the two phases. The dispersed cannabinoid or mixture of cannabinoids is enclosed within the polymer film.
Nano-encapsulation of isomers of tetrahydrocannabinol (THC) maintains a reactive material in an inert stage until such time as it is called upon to perform a given function. Thus, inertness is provided by interposing, by encapsulation, a non-reactive barrier or shell between the reactive material and its immediate surrounding. Removal of the barrier or shell by any suitable means activates the encapsulated cannabinoids that are present in the cannabinoid nano-suspension. In this manner, the handling properties of solids can be conferred on liquids and gases. The nano-encapsulated cannabinoid composition is maintained inactive until the shell is ruptured by pressure of a stylus or other means.
The term “nano-suspension” as used herein refers in a non-limiting sense to a cannabinoid nanoparticle as an active ingredient that is coated with a suitable protective layer and when the cannabinoid is taken internally, has a delayed affect or sustained release affect or extended release affect but remains inactive until the polymer layer is dissolved. As is apparent, depending on the encapsulating shell present in the cannabinoid nano-suspension, the influence of the drug can be delayed from a matter of minutes up to several hours or released even more rapidly with faster therapeutic benefits.
Although several methods are presently known for nano-encapsulation of cannabinoids, such as the nano-encapsulation of a THC oil with a lipid shell utilizing a coacervation process. The prior processes are focused on THC extracted from marijuana and further purified with various technologies used in the market today, but the prior processes exclude nano-encapsulation of cannabinoid nanoparticle or mixture of cannabinoid nanoparticles that are purified via molecular distillation to a higher level of purity. Furthermore, the existing suspension-evaporation method used for nano-encapsulation of THC is limited in scope to specific procedures of extraction and separation and purification and further steps to produce a cannabinoid nanoparticle of 50 to 1000 nm in size to preferably 100 to 500 nm in size.
The term “vacuum”, as used herein, refers in a non-limiting sense to the low pressure distillation conditions used in the centrifugal distillation process described herein.
The term “Winterization”, as used herein, refers in a non-limiting sense to combining extracted CBD oil with ethanol and freezing overnight, which is then filtered to remove fats and other impurities, and the filtrate is heated to evaporate the ethanol.
The embodiments herein, and/or the various features or advantageous details thereof, are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concepts to those skilled in the art.

FIG. 7 is a graphic illustration that shows a non-limiting embodiment of a molecular/centrifugal distillation apparatus. The Centrifugal Distillation System (Pilot 15, from Myers) utilizes thermal separation process in order to obtain vaporizable liquids from a gas phase and to separate substances that are difficult to vaporize, wherein a cannabinoid containing extract is enriched in the distillate. This molecular distillation unit is designed to distill materials in the pressure range from 700×10-3 Torr down to 1×10-3 Torr. The lower the pressure, the lower the heat required to effect distillation. The lower the heat, the lower the chance of damaging the product and reduces the energy costs required for the purification process. The molecular distillation unit has a complete vacuum system as can be seen from the diagram. Both the degasser and the high vacuum distillation chamber have vapor traps; these vapor traps are cooled by liquid Nitrogen or equitant medium. A diffusion-ejector pump and a rotary vane vacuum pump evacuate the main chamber. The degasser has a separate rotary vane vacuum pump. There are three regions of pressure monitoring. This enables the operator to get accurate pressure measurements in the three critical areas: the degasser, the high-vacuum chamber, and the fore line.
Centrifugal Distillation
The molecular centrifugal distillation unit is designed as a continuous flow, vacuum distillation system. The diagram in FIG. 7 illustrates the flow of material through the still. The raw cannabinoid oil substrate is pumped from the supply/feed tank by a variable speed feed pump (12) into the degasser. In the degasser small amounts of low boiling materials such as any volatiles that may be incorporated into the cannabinoid mixture and trapped gases are removed to enable more efficient vacuum distillation at the next stage.
Referring now to graphical illustration FIG. 7 and flowchart FIG. 8 to describe the process of using the centrifugal distillation system, a feed pump (6) moves the degassed material onto the center of a heated, spinning Rotor (11) in the high vacuum distillation chamber (10). On the Rotor the cannabinoid or mixture of cannabinoids spread out into a thin film. As the cannabinoid spreads across the Rotor, a certain portion (the distillate) evaporates. The cannabinoid fraction which distills is selected by the operator by adjusting the temperature. Once set, this remains constant until the production run is completed or until new conditions are selected.
The distillate cannabinoid vapor condenses in the vacuum chamber on a water-cooled condenser in Chamber (10) and moves to a separate liquid transfer pump and is removed from the system through check valve to atmosphere. The raw cannabinoid oil portion which does not distill, (the residue) flows off the edge of the rotor to be contained by a separate gutter and moves to another liquid transfer pump through a check valve to atmosphere.
Depending upon the raw cannabinoid oil material or process requirements, either the distillate or the residue may be your final product. In many cases both cannabinoid fractions may be of value.
Processing
As described in FIG. 7 and FIG. 8, the product path through the molecular centrifugal distillation unit is heated in separate zones. The zones can be temperature regulated for conditioning of the product for various steps in the process. They are the degasser feed line, the degasser wall, the rotor feed line, rotor heater temperature, distillate line and residue line. The control center offers displays of the three vacuum stations, the actual and set point temperatures of the degasser pre-heater, degasser heater, the rotor pre-heater, the rotor heater, residue line heater and distillate line heater. The operator controls the process by setting the feedstock rate (How thick the material will be on the rotor) and the rotor heater temperature.
Equipment in Detail
As described in FIG. 7 and FIG. 8, the molecular centrifugal distillation unit receives process cannabinoid or mixture of cannabinoids supplied from a storage tank. This cannabinoid material passes through stainless steel pipes through the variable speed feed pump. This pump controls the flow rate of material through the molecular centrifugal distillation system. From the feed pump the cannabinoid material passes along a length of heated pipe before entering the degasser. Preheated cannabinoid material enters a rotating cup within the degasser and is spun onto the heated walls to quickly out gas the cannabinoid material. The cannabinoid media runs down and is collected on the heated base. Degassed material passes, via a pipeline, to the distillation chamber feed pump.
From the feed pump the cannabinoid material passes along a length of pipe, which is heated to reduce any heat loss, before entering the centrifugal distillation chamber. In the centrifugal distillation chamber the cannabinoid material is introduced onto the center of the spinning rotor disk and is spread across the heated surface. The surface area increases exponentially as cannabinoid material travels across the disc thus exposing more cannabinoid material to the surface for evaporation as it travels across. The cannabinoid material will separate into a vapor phase, the distillate, depending on the operators' combination choice of temperature and pressure. The remaining cannabinoid material is the residue.
The distillate vapor is condensed on a water-cooled surface and flows down the chamber walls and out to the distillate pump. The residue passing across the full surface of the rotor is collected in a surrounding gutter and flows out of the chamber to the residue pump. On the exit of each pump is a non-return valve to isolate the distillation chamber from atmospheric pressure. Both the degasser and distillation chambers have independent vacuum pumping systems which are protected with individual traps.
The traps in each vacuum line are refrigerated to protect from cross-contamination with the vacuum pump fluids. Both traps have drain taps, which are used to empty the traps while the molecular centrifugal distillation unit is shut down and at atmospheric pressure. Trap collection vessels or gear pumps can be added to drain the traps while the molecular distillation unit is running and are supplied as an option. The degasser vacuum pump is a direct drive rotary vane positive displacement pump with exhaust to the atmosphere. The distillation chamber vacuum pumps are a diffusion-ejector pump backed by a direct drive rotary vane positive-displacement pump with exhaust to the atmosphere. System pressures are monitored at the degasser, distillation chamber, and the ejector pump fore line.

Example 20
Solvent Injection Technique
Solvent Injection Technique dissolves lipid materials and lipophilic substances in a water-miscible organic solvent, and then the organic phase is injected into a large amount of aqueous buffer, resulting in unilamellar vesicle liposomes (Small UVs, Large UVs) being spontaneously formed. In another method, two streams of solution are injected/infused through the Y-connector and membrane contactors in a tubular device to improve the micromixing of the organic phase into the aqueous phase. The solvent rapidly diffuses in an aqueous medium, and interfacial turbulence leads to the formation of small and homogenous liposomes. The particle size between 80 nm and 300 nm is prepared depending on the preparation conditions. Additional energy input for particle size reduction, such as sonication and extrusion, is not required. The organic solvent is removed using evaporation, lyophilization, dialysis, or diafiltration, and the liposomes suspensions may be concentrated to a desired volume. Ethanol is commonly used as an organic solvent because of its safety. Various preparation parameters, including the flow rate, the temperature of both solvent and aqueous solution, the lipid concentration, as well as the stirring rate, affect the properties of particles.

Nano-Encapsulation
Accordingly, the invention provides a simplified method of nanoencapsulation wherein the capsule shell consists of a lipid composition that encapsulates high purity cannabinoid nanoparticles or mixture of high purity cannabinoid nanoparticles that maintain the size of said cannabinoid nanoparticles. The invention provides a simplified method of encapsulating cannabinoids that have been highly purified via molecular distillation prior to a wide variety of mixing or homogenization or sonication or high shear blending resulting in cannabinoid nanoparticles of the highest stability and purity. The invention provides a nano-suspension of encapsulated cannabinoid product having an infusible polymer shell. The invention provides a nano-suspension of encapsulated cannabinoid product wherein the product is readily dispersed or suspended into an aqueous solution. The invention provides a nano-suspension of encapsulated cannabinoid product having high uniformity of thickness of the polymeric capsule shell. The invention provides a dry, free-flowing, discrete nanoscopic cannabinoid capsule in said cannabinoid nano-suspension.
The invention provides a sequence that obtains cannabinoid nanoparticles or mixture of cannabinoid nanoparticles from unpurified raw cannabinoid oil to a purified cannabinoid resulting from the extraction or purification using a molecular distillation process that forms a high purity cannabinoid prior to its nano-suspension into an aqueous or non-aqueous media nanoencapsulation. Essentially, the process comprises bringing a cannabinoid or mixture of cannabinoids together with a lipid or lipophilic substance that when mixed together in the proper sequence produces cannabinoid nanoparticles of size ranging from 50 to 1000 nm and preferably 100 to 500 nm in size.

Example 24
Nano-Emulsions
The invention provides, at the reaction interface where condensation of the cannabinoid occurs said cannabinoid composition substantially and instantaneously forms a thin film of cannabinoid or mixture of cannabinoids which is insoluble in the parent media of the lipid composition that will result in the formation of the cannabinoid or mixture of cannabinoid nanoparticles. The preferred and mechanically most simple method of providing the interface for nano-suspension is to disperse or emulsify one cannabinoid or a mixture of cannabinoids for the condensation polymer in a continuous phase containing the second reactant. The cannabinoid substance to be processed into a cannabinoid nano-encapsulation will also be contained in the dispersed phase. However, in order to more accurately control the formation of the nano-suspension, it can be convenient to emulsify or disperse one cannabinoid or mixture of cannabinoids for the condensation polymer, together with the substance to be nano-suspended in a continuous phase and thereafter add additional continuous phase containing the second reactant to the dispersion. The polycondensation polymer shell will form at the interface of the dispersed cannabinoid composition and encapsulate the material resulting in a cannabinoid nano-suspension. The suspension or nanoparticle. The dispersion or emulsion can be stabilized by addition of surface active agents, or surfactants, or co-surfactants or protective colloids to the continuous phase. The dispersion or emulsion can be produced by the standard suspension and emulsification techniques known in the art. Emulsions or dispersions can be prepared by agitation, preferably in the presence of one or more emulsifying agents. The efficiency of the emulsification depends among other factors, on the type and degree of agitation and the manner in which the emulsifying agent is introduced. The primary function of the agitation is to break up both phases of the emulsion so that the one which will become the dispersed phase is able to form small globules. The emulsifier is employed to lower the interfacial tension since the lower the interfacial tension the lower the amount of mechanical energy needed to break up the phases. Where the interfacial tension of a system is extremely low, spontaneous emulsification may result. The preparation of the emulsions can be facilitated by various types of colloid mills and homogenizers engineered to obtain maximum shear action of the fluid and enhance the formation of fine uniform globules. The use of such emulsifier will result in a more stable cannabinoid nano-suspension and can also result in a more effective cannabinoid nano-suspension which can deliver greater therapeutic effects.
Emulsifying agents which are operable in preparing the emulsions or dispersions or suspensions that will be used to produce the cannabinoid or mixture of cannabinoid nanoparticles include the long chain polar and non-polar compounds, as well as the more complex hydrophilic colloids, such as gums, starches, proteins, etc. which are known to be readily adsorbed at the phase interfaces. In addition to high shear agitation with or without emulsifier, the nano-suspension dispersion can be formed by injecting one phase into a second phase from an orifice at a rate designed to exceed the critical velocity required for continuous flow. A solid phase containing one cannabinoid or mixture of cannabinoids may be dispersed into a continuous medium containing the second reactant. The continuous medium may contain the second reactant or a solution of the second reactant also as a discontinuous phase. Such would be the case when a liquid or solid medium containing the first cannabinoid or mixture of cannabinoids is dispersed into a continuous phase containing a fine dispersion of the second reactant resulting in a more effective cannabinoid nano-suspension. The effective reactive area of the second reactant can be increased by reducing the particle size of its dispersion and thus resulting in the formation of cannabinoid or mixture of cannabinoid nanoparticles.
