DETAILED DESCRIPTION OF THE DRAWINGS

[0026] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present teachings and arrangements. It will be apparent, however, to one skilled in the art that the present teachings and arrangements may be practiced without limitation to some or all these specific details. By way of example, the present systems and methods are described in terms of batch mode of operation, but continuous mode of operation is equally applicable to implement the present teachings. In other instances, well-known process steps have not been described in detail in order to not unnecessarily obscure the present teachings and arrangements.

[0027] FIG. 1 shows a sanitizing composition producing system 100, according to one embodiment of the present arrangements, for producing sanitizing compositions. Sanitizing composition producing system 100 is generally a multi-stage reactor assembly and, preferably a two-stage reactor assembly. To this end, sanitizing composition producing system 100, preferably, includes two reactors disposed adjacent to their respective downstream homogenizing subassemblies, i.e., a first reactor 102 disposed downstream from a first homogenizing subsystem 120 and a second reactor 122 disposed downstream from a second homogenizing subsystem 140. The homogenizing subsystems serve to homogenize the fluid contents inside their respective reactors so that by repeated reaction, homogenization and recirculation of such fluid contents, an effective sanitizing composition of the present teachings is produced.

[0028] Inside first reactor 102, fluid 104 represents an intermediate sanitizing composition that is conveyed downstream from a first outlet line 106 to first homogenizing subsystem 120 (shown in greater detail in FIG. 2A). First homogenizing subsystem 120 includes a first motor 108 rotationally driving a first axle 111 that longitudinally extends inside a first shaft 110, which preferably includes a bushing to receive a first homogenizing blade 112. Further, a first rotor 113 is received within a central region of a first homogenizing blade, defining a first gap there-between. In this configuration, first axle 111 connects to a first rotor 113 such that during an operative state of first homogenizing subsystem 120, a rotating action of first axle 111 causes first rotor 113 to rotate. In this operative state of first homogenizing subsystem 120, the rotation action of first rotor 113 occurs relative to a first homogenizing blade 112, which is preferably not rotating. As will be explained below, fluid passing through a first rotor/homogenizing blade subassembly 115 (e.g., specifically a first gap defined by a space between first rotor 113 and first homogenizing blade 112) undergoes effective homogenization.

[0029] Intermediate sanitizing composition homogenized at first homogenizing subsystem 120 recirculates, preferably using a three-way valve 114 and first recirculation line 116, from and back to first reactor 102. To facilitate such recirculation, one or more valves (e.g., three-way valve 114), in one setting, is set to prevent fluid flow from outlet line 106 to flow into an input line 118, thereby directing flow through first recirculation line 116 and back to first reactor 102. In this setting, a recirculation loop around first reactor 102 and first homogenizing subsystem 120 is formed to effectively repeatedly subject the intermediate sanitizing composition to undergo, for a certain time duration, reaction and mixing inside first reactor 102, homogenizing inside first homogenizing subsystem 120 and recirculation using one or more valves and through first recirculation line 116, until the intermediate sanitizing composition is an alcohol and water solution of a predefined concentration. By way of example, the alcohol in the intermediate sanitizing composition may range from about 65% (by volume) to about 95% (by volume). In one embodiment of the present arrangements, to effectively react the alcohol and water mixture inside first reactor 102 at the appropriate reaction temperatures, outer walls of first reactor 102 are surrounded by a heating jacket. In certain embodiments, the repeated steps of reaction and mixing, homogenizing and recirculation are carried out for a predefined time duration that ensures that the components (e.g., alcohol and/or water) are present in the intermediate composition at the requisite concentration or one or more different types of sensors (e.g., concentration sensors) are used to ensure that the predefined component concentrations are reached so that preparation may be made to commence the next stage of reaction.

[0030] After a predefined time duration of reaction, homogenization and/or recirculation, and/or after reaching an intermediate sanitizing composition having desired concentration of chemical components present therein (e.g., alcohol and/or water), the intermediate sanitizing composition may be cooled to within a desired temperature range and then transferred through one or more valves (e.g., a three-way valve 114) and to input line 118 so that processing may commence at the second stage of reaction and mixing. Specifically, one or more valves (e.g., a three-way valve 114) is set to prevent fluid from first outlet line 106 to flow into recirculation line 116 and allowed to convey the intermediate composition to second reactor 122.

[0031] In connection with the second stage of reaction, second reactor 122, a second outlet line 126, second homogenizing subsystem 140 (shown in greater detail in FIG. 2B), which includes a second motor 128, a second shaft 130, and a second rotor/homogenizing blade subassembly 135, each of which are substantially similar to and arranged similar to their counterparts discussed with respect to first reactor 102, e.g., first outlet line 106, first homogenizing subsystem 120, first motor 108, first shaft 110, and first rotor/homogenizing blade subassembly 115. Second reactor 122 may be operating at a temperature that ranges from about 10° C. and to 30° C. and is, preferably, operating at or below room temperature. Intermediate sanitizing composition of a desired composition and sufficiently homogenized is, preferably, cooled to arrive at a “cooled-intermediate sanitizing composition” and then conveyed through valve 114 and input line 118 to second reactor 122.

[0032] At the relatively low prevailing temperatures inside second reactor 122 and using second homogenizing subsystem 140, the first homogenized composition of alcohol and water is repeatedly reacted, mixed, homogenized and/or recirculated to produce a second homogenized solution 124, which is, preferably, the effective sanitizing composition of the present teachings. In other embodiments of the present arrangements, one or more additional stages of reacting, mixing, homogenizing and/or recirculation may be carried out, but the arrangement of FIG. 1 represents a preferred embodiment of the present arrangements. If additional reaction stages are used, then another set of one or more valves (e.g., three-way valve 134) along with a two-stage homogenized sanitizing composition outlet 138 is used to convey a two-stage homogenized sanitizing composition for further reaction, homogenization and/or recirculation to a downstream reaction stage for further processing. If additional reaction stages are not used, then another set of one or more valves (e.g., three-way valve 134) and two-stage homogenized sanitizing composition outlet 138 are used to dispense the sanitizing composition of the present teachings.

[0033] In certain embodiments of the present arrangements, one or more inlets into first reactor 102 and/or second reactor 122 are provided to supply any at least member chosen from a group comprising thickening agent, additive and fragrance. Regardless of the type of contents received inside first reactor 102 and/or second reactor 122, these contents undergo homogenization to produce an effective sanitizing composition.

[0034] FIG. 2A shows in greater detail first homogenizing subsystem 120, which includes first motor 108 for rotationally driving a first axle 111 that is coupled to first rotor 113. In an assembled configuration of first homogenizing subsystem 120, first axle 111 longitudinally extends inside first shaft 110, which is preferably fitted with a bushing that couples to a first homogenizing blade 112. During an operative state of first homogenizing subsystem 120, a rotational action of first axle 111 cause first rotor 113 to rotate relative to homogenizing blade 112, which is preferably not rotating. In this operative state of the assembled configuration shown in FIG. 2A, the intermediate sanitizing composition flows through a first gap defined between first homogenizing blade 112 and first rotor 113, and thereby undergoes homogenization. Specifically, first homogenizing blade 112 have multiple first homogenizing teeth 117 that, in an operative state, facilitate homogenization of the intermediate sanitizing composition or any fluid passing through the first gap.

[0035] As shown in FIG. 2A, first homogenizing teeth 117 protrude from a first teeth base portion, which is denoted by “d” and facilitate the homogenization of the intermediate sanitizing composition having a viscosity that ranges from about 1.05 cp to about 1.2 cp. In one embodiment, “d,” in first homogenizing blade 112, ranges from about 0.5 mm and about 1.2 mm to achieve the effective homogenization of the intermediate sanitizing composition.

[0036] FIG. 2B, similar to FIG. 2A, shows in greater detail second homogenizing subsystem 140, which, in an assembled configuration, includes second motor 128 rotationally driving a second axle 130 that is coupled to second rotor 133. Further, second axle 131 longitudinally extends inside second shaft 130, which is, preferably, fitted with a bushing that couples to a second homogenizing blade 132.

[0037] During an operative state of second homogenizing subsystem 140, motor 128 causes rotational motion of first axle 131, which in turn rotationally displaces first rotor 133 relative to second homogenizing blade 132, which is preferably not rotating. In this operative state, sanitizing composition 124 shown in FIG. 1 flows through a second gap defined between second homogenizing blade 132 and second rotor 133 undergoes homogenization. Specifically, second homogenizing blade 132 having multiple second homogenizing teeth 137 that, in an operative state, facilitate homogenization of sanitizing composition 124 passing through the second gap.

[0038] As shown in FIG. 2B, second homogenizing teeth 137 protrude from a second teeth base portion, which is denoted by “d.” In one embodiment, “d” (e.g., inside second homogenizing subsystem 140) is sufficiently large to effectively homogenize a mixture of alcohol and water solution in the second reaction stage (e.g., inside second reactor 122) having a viscosity that ranges from about 1.05 cp to about 1.2 cp. In preferred embodiments, “d” ranges from about 1.25 mm and about 3.5 mm to achieve the effective homogenization of sanitizing composition 124.

[0039] First axle 111 and/or second axle 131 are, preferably, specialized dispersing axles, which, in one operative state, have a rotational speed ranging from about 10,000 rotations per minute (“rpms”) to 30,000 rpms to effectively disperse relatively viscous compositions of the intermediate sanitizing compositions and/or sanitizing compositions of the present teachings.

[0040] The present teachings also provide methods for producing hand-sanitizing compositions. Certain of these methods need not be carried out using structural details described in connection with FIG. 1 or otherwise. FIG. 3 shows a flowchart for a method 300, according to one preferred embodiment of the present teachings, for producing the present sanitizing compositions.

[0041] Method 300 begins with a step 302, which involves mixing, using a reactor at a reaction temperature that is between about 50° C. and about 70° C., alcohol with a cannabidiol (“CBD”) and/or a cannabigerol (CBG) to produce an intermediate sanitizing composition, in which the alcohol is present in a concentration that ranges from about 75% (by volume) to about 95% (by volume). In preferred embodiments of step 302, in one part by volume of alcohol, each of CBD or CBG is also present in about one part by volume. In other words, the ratio of alcohol to each CBD or CBG is, preferably, approximately 1:1 when mixing alcohol with either of the two. In those instances where a mixture of CBD and CBG is used to form the intermediate sanitizing composition, for one part by volume of alcohol, a mixture of CBD and CBG is present in about one part by volume (i.e., ratio of alcohol to a mixture CBD and CBG is, preferably, approximately 1:1).

[0042] Step 302 may include receiving different types of raw materials, such as alcohol, CBD and/or CBG, or may include additives, such as thickening agents or fragrances. Each of the raw material and/or thickening agents are preferably stored in their respective reservoirs and are conveyed through their respective input lines to first reactor 102 and/or second reactor 122 as is deemed desirable.

[0043] Next, a step 304 including cooling the intermediate sanitizing composition to a temperature that ranges from about 10° C. to about 30° C. to produce a “cooled intermediate sanitizing composition.” In a preferred embodiment of step 304, the cooling step includes cooling the intermediate sanitizing composition to a relatively lower temperature, which is cooler than the reaction temperature of alcohol and water solution at the first reaction stage (e.g., inside first reactor 102).

[0044] In one implementation of the present teachings, method 300 may include a conveying step that includes batchwise conveying the cooled intermediate sanitizing composition from first reactor 102 to second reactor 122 at an appropriate time after lapse of a predefined time duration of the intermediate sanitizing composition undergoing homogenization and recirculation in the first reaction stage or when one or more predefined conditions (e.g., temperature) for the cooled intermediate sanitizing composition are achieved. One or more additives, such as lavender essential oil, hemp essential oil, terpenes and hydrosols may be introduced into first reactor 102 and/or into second reactor 122 (i.e., introduced when the cooled intermediate sanitizing composition is present inside second reactor 122).

[0045] Then, a step 306 requires admixing the cooled intermediate sanitizing composition with an alcohol water solution to produce the sanitizing composition, wherein the concentration of the alcohol ranges from about 65% to about 95% (by volume).

[0046] Although the present teachings do not limit the different steps involved in producing a sanitizing composition to be carried out in any particular order, preferred embodiments of the present teachings recognize that the lipophilic nature of CBD or CBG desire a specific order in which the steps should be carried out. According to these preferred embodiments, prior to cooling step 304, methods 300 involve preparing the intermediate sanitizing composition for thickening by cooling the intermediate sanitizing composition to a temperature that ranges from about 30° C. and to 50° C. to produce a thickened intermediate sanitizing composition. I n more preferred embodiments, the preparing step of the present teachings is carried out by cooling the intermediate sanitizing composition to room temperature or even lower temperatures to achieve the requisite thickening.

[0047] One embodiment of the preparing step includes introducing into a first reactor (e.g., first reactor 102 of FIG. 1) a thickening agent to produce a thickened intermediate sanitizing composition. By way of example, the thickening agent is glycerin and/or an aloe-based compound. The preparing step to produce the thickened intermediate sanitizing composition may include introducing into the reactor one or more different types of fragrances. The fragrance may be an essential oil, such as a hemp-based essential oil and/or a lavender-based essential oil.

[0048] In preferred embodiments, method 300 further comprises recirculating, using a first recirculation line (e.g., first recirculating line 116 of FIG. 1), an intermediate sanitizing composition (e.g., intermediate sanitizing composition 104 of FIG. 1) from a first reactor (e.g., first reactor 102 of FIG. 1) back to the first reactor. This recirculating step is performed prior to step 306 of admixing the cooled intermediate sanitizing composition with an alcohol water solution to produce the sanitizing composition.

[0049] In this preferred embodiment, method 300 also comprises homogenizing the intermediate sanitizing composition using a first homogenizing blade (e.g., first homogenizing blade 112 of FIG. 2A) having a first homogenizing teeth (e.g., first homogenizing teeth 117 of FIG. 2A) that protrude, from a first teeth base portion, a distance (e.g., protruding distance “d” shown in FIG. 2A) ranging from about 0.5 mm to about 1.2 mm. In this configuration, the first homogenizing blade is disposed on the first recirculating line as shown in FIG. 1 and homogenization is carried out by, preferably, passing the intermediate sanitizing composition through a first gap defined between a first rotor and a first homogenizing blade. In this manner, method 300, preferably includes repeated mixing step 302, i.e., reacting, homogenizing and/or recirculating.

[0050] In preferred embodiments, method 300 similarly further comprises recirculating, using a second recirculation line (e.g., second recirculating line 136 of FIG. 1), a sanitizing composition (e.g., sanitizing composition 124 of FIG. 1) from a second reactor (e.g., second reactor 122 of FIG. 1) back to the second reactor. In this preferred embodiment, method 300 also comprises homogenizing the sanitizing composition using a second homogenizing blade (e.g., second homogenizing blade 132 of FIG. 2B) having a second homogenizing teeth (e.g., second homogenizing teeth 137 of FIG. 2B) that protrude, from a second teeth base portion, a distance (e.g., protruding distance “d” shown in FIG. 2B) ranging from about 1.25 mm to about 3.5 mm. In this configuration, the second homogenizing blade is disposed on the second recirculating line as shown in FIG. 1 and homogenization is carried out by, preferably, passing the sanitizing composition through a second gap defined between a second rotor and a second homogenizing blade. In this manner, method 300, preferably includes repeated admixing step 306, i.e., reacting, homogenizing and/or recirculating in the second stage of processing.

[0051] The present teachings also offer effective sanitizing compositions to sanitize skin (e.g., hand) and various surfaces. In one preferred embodiment of the present teachings, present sanitizing compositions comprise effective amounts of an alcohol for disinfecting and effective amounts of CBD and/or CBG for disinfecting and serving as inflammation reducing agent. In the event the sanitizing composition is used on skin, effective amounts of alcohol that sanitize the skin undesirably causes skin inflammation. In these preferred embodiments, effective amounts of alcohol ranges from about 60% (by volume) to about 95% (by volume) and effective amounts of CBD ranges from about 0.1% (by volume) to about 0.4% (by volume), and effective amounts of CBG ranges from about 0.01% (by volume) to about 0.1% (by volume). The present sanitizing compositions have a viscosity that ranges from about 1.05 cp to about 1.2 cp.

[0052] The present sanitizing composition comprises water acting as a carrier fluid and present, preferably, in a concentration that ranges from about 25% (by volume) to about 35% (by volume). In this preferred embodiment, the present sanitizing composition further comprises a thickening agent that includes glycerin and/or aloe. Preferably, glycerin is present in a concentration that ranges from about 1% (by volume) to about 2% (by volume), and aloe is present in a concentration that ranges from about 1% (by volume) to about 5% (by volume).

[0053] The present teachings also contemplate the possibility that hand-sanitizing compositions of the present teachings may further include additives (e.g., essential oils) which impart fragrance upon application of the sanitizing compositions. By way of example, such additives include one or more compounds chosen from a group comprising lavender essential oil, hemp essential oil, terpenes and hydrosols. Further, the additives may be present in a concentration that ranges from about 0.01% (by volume) to about 5% (by volume).

[0054] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present teachings and arrangements. It will be apparent, however, to one skilled in the art that the present teachings and arrangements may be practiced without limitation to some or all of these specific details. In other instances, well-known process steps have not been described in detail in order to not unnecessarily obscure the present teachings and arrangements.
