Description

TITLE OF THE INVENTION

[0001] Cold Processable Emulsion Concentrates Providing Desirable Sensory Properties,

End Use Formulations Containing the Emulsion Concentrates and Related Methods

CROSS REFERENCE TO RELATED APPLICATION

[0002] This application claims the benefit under the Paris Convention and 35 U.S.C.

§119(e) of U.S. Provisional Patent Application No. 62/512,353, filed May 30, 2017, entitled " Cold Processable Emulsion Concentrates Providing Desirable Sensory Properties,

End Use Formulations Containing the Emulsion Concentrates and Related Methods," the entire disclosure of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

[0003] An emulsion can be considered a dispersion of one material inside of another, non- miscible phase. In cosmetics and personal care, the two phases in an emulsion are oil and water/aqueous phases. Emulsion technologies are used widely in the personal care industry as they provide formulators with the ability to prepare compositions that contain both oil- miscible and water-soluble components. For example, emollient components tend to be lipophilic in nature, whereas moisturizers demonstrate mostly hydrophilic characteristics. Other components such as natural extracts, active ingredients, essential oils, fragrances, preservatives, colors and tints all exhibit a preference to either the oil or water phase.

Emulsion technologies allow for the uniform mixture of these ingredients.

[0004] However, conventional methods for processing such emulsions require significant quantities of energy and time - energy is used for heating and cooling, and often water is used for cooling too. Indeed, it is reported that over 90% of the total energy cost for the production of is attributable to the energy expended for heating or cooling.

[0005] As personal care consumers continue insisting on eco-friendly materials and processes, cold process emulsion technologies have gained popularity, reducing both the energy demand and manufacturing time required. Some report that cold process emulsification can save up to 75% of energy compared to a conventional (hot) process. Moreover, significantly less water is used in those processes that rely in water for a cooling function. Thus, personal care and cosmetic formulations prepared using cold process emulsions can be promoted to consumers as having lower carbon and lower water footprints as compared to conventional formulations. Other benefits accrue to the manufacturer: cost savings due to reduction in energy, cost savings due to less time in production, safer production processes, and no limitation on heat sensitive ingredients in the formulations.

[0006] Moreover, if one is able to provide a cold process emulation in a concentrate form, further advantages can be realized. For example, carbon footprint and costs are reduced further as transportation of concentrates is significantly less expensive and energy intensive than shipping materials with a higher water amount.

[0007] Cold process ingredients, such as emulsifiers, enable the manufacturer to reduce water (when water is used as a coolant) and energy consumption, and also the time taken to manufacture emulsions.

[0008] Thus, there remains a need in the art for emulsion concentrates that provide the emulsion functionality as well as the sensory and skinfeel property of traditional, heat processed, emulsions.

BRIEF SUMMARY OF THE INVENTION

[0009] An emulsion concentrate that includes an ester oil, a nonionic ester emulsifier, a waxy ester, and an aqueous cationic surfactant.

DETAILED DESCRIPTION OF THE INVENTION

[0016] The invention includes an emulsion concentrate having various applications and utilities: for example, one may dilute it with or disperse it within an additional carrier, preferably water or a floral water, to prepare various personal care products such as hair treatments, lotions and creams, or various home care products, such as surface cleaners and dish cleansers; one may use in the preparation of a carrier or dispersion delivery system for pharmaceuticals, pigments, colorants, fragrances, crop/plant fertilizers and nutrients, and/or pesticides; one may use it in diluted/dispersed or undiluted/undispersed form to impregnate textiles, woven or unwoven, such as baby wipes or makeup removal wipes.

[0017] Unexpectedly, it has been found that the emulsion concentrate of the invention (and formulations prepared using it) provides a sensory experience that is less tacky or sticky, while remaining smooth and silky-feeling as compared to the prior art compositions, whether it is applied to skin or other surface neat, in an end use formulation or via an applicator (e.g. , a wipe).

[0018] The emulsion concentrate includes at least one of an ester oil, e.g. , an oil containing compounds having one or more ester linkages. Any ester oil or combination of ester oils may be used, including oils that are synthetic or derived from vegetable or animal sources, such as castor bean, palm, rapeseed and/or coconut. Medium chain triglycerides may be preferred for use as the oil. In an embodiment, the oil is glycerol triheptanoate, such as that for example, available from INOLEX, Inc. under the trade name SustOleo MCT.

[0019] The ester oil may be present in the emulsion concentrate in any amount. As would have been perceived by a person of skill in the art, the relative amounts of the ingredients described herein for inclusion in the emulsion concentrate will vary depending on the end application.

[0020] It may be preferred, however, that the ester oil is be present in the emulsion concentrate in any amount. It may be preferred that the ester oil is present in an amount of about 20% to about 80%, about 30% to about 70%, about 35% to about 60% and about 40% to about 50%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation). In some embodiments the ester oil is present in an amount of about 45%, about 45.5%, about 46%, about 46.5%, about 47%, about 47.5%, about 48%, about 48.5%, about 49%, about 49.5%, and about 50% each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation).

[0021] Also included in the emulsion concentrate is one or more nonionic ester emulsifiers. Any may be used depending on the end application. Preferred in some embodiments may be esters of polyethylene glycol (PEG), such as PEGs 6-12, sucrose-based emulsifiers, such as sucrose laurate, sucrose palmitate, sucrose stearate, and sucrose oleate, and/or polysorbate emulsifiers, such as poly oxy ethylene sorbitan monolaurate (Polysorbate 20), polyoxy ethylene sorbitan monopalmitate (Polysorbate 40), poly oxy ethylene sorbitan monostearate (Polysorbate 60), and poly oxy ethylene sorbitan monooleate (Polysorbate 80), and glycerol esters, such as glycerol stearate, 2 ethyl hexyl oleate, glycerol trioleate, glyceryl monooleate, glyceryl monotallate, or pentaerythritol monooleate.

[0022] In an embodiment that may be preferred for personal care and cosmetics

applications, the nonionic ester emulsifier is glyceryl stearate (glyceryl monostearate). In an embodiment, the nonionic ester emulsifier is a glyceryl stearate sold by INOLEX, Inc., under the trade name SustOleo GMS.

[0023] The ester emulsifier may be present in the emulsion concentrate in any amount. It may be preferred that the ester emulsifier is present in an amount of about 1% to about 50%, about 3 to about 40%, about 5% to about 30% and about 10% to about 20%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation). In some embodiments the ester emulsifier is present in an amount of about 5%, about 5.5%, about 6%, about 6.5%, about 7%, about 7.5%, about 8%, about 8.5%, about 9%, and about 9.5%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation).

[0024] Additionally included in the emulsion concentrate is at least one waxy ester, saturated or unsaturated, e.g. , any ester that results from the esterification of a fatty acid and a fatty alcohol. The waxy ester may be synthetic or derived from a plant or an animal. Preferred for some embodiments may be waxy esters obtained from C12 -C24 fatty acids and/or C24-C34 fatty alcohols.

[0025] In an embodiment described herein, the waxy ester is a hydrogenated rapeseed oil. However, the waxy ester may be any source oil. The waxy ester may be synthesized, or simply derived from the hydrogenation of any naturally occurring, such as those listed infra, as the hydrogenation of any liquid natural triglyceride oil renders it "waxy" or "solid."

[0026] Preferred may be waxy esters that contain one or more glycerol esters, e.g. , triglycerides or a combination of tri-, mono- and di-glycerides. In some embodiments, one may prefer that the selected waxy ester contains a combination of glycerol tristearate and glycerol tribehenate (tribehenin).

[0027] Suitable vegetable sources for the waxy ester may include hydrogenated vegetables oils such as rapeseed oil, peanut oil, safflower oil, coconut oil, soybean oil, palm oil, olive oil, corn oil, hazelnut oil, linseed oil, rice bran oil, acai oil, Jambu oil, Guava oil, sesame oil, graviola oil, tucuma oil, brazil nut oil, carapa oil, buriti oil, passion fruit oil, pracaxi oil, and/or esters derived from or isolated from these oils or combinations of the same.

[0028] In an embodiment, the waxy ester is a hydrogenated rapeseed oil sold by INOLEX, Inc., under the trade name SustOleo TSB.

[0029] However, it may be preferred that the oil or oil is present in an amount of about 1% to about 50%, about 3 to about 40%, about 5% to about 30% and about 10% to about 20%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation). In some embodiments the oil or oils is present in an amount of about 5%, about 5.5%, about 6%, about 6.5%, about 7%, about 7.5%, about 8%, about 8.5%, about 9%, and about 9.5%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation).

[0030] The emulsion concentrate of the invention preferably includes a cationic surfactant, preferably aqueous. Any may be used, such as, for example, behentrimonium chloride, benzalkonium chloride, benzethonium chloride, bronidox, betrimonium bromide, cetrimonium chloride, dimethyldioctadecylammonium bromide,

dimethyldioctadecylammonium chloride, lauryl methyl gluceth-10 hydroxypropyl dimonium chloride, octenidine dihydrochloride, olaflur N-Oley 1-1,3 -propanediamine, stearalkonium chloride and tetramethylammonium hydroxide, and/or thonzomuni bromide. In some embodiments it is preferred that the cationic surfactant is is an alkyamido propyl PG-dimonium chloride, more preferably, cocamidopropyl PG-dimoinum chloride. [0031] In an embodiment, it is a cocamidopropyl PG-dimoinum chloride sold by INOLEX, Inc. under the trade name LEXQUAT C-PF. LEXQUAT C-PF is supplied as a 35% active solution in water.

[0032] The cationic surfactant in the form of an aqueous solution having 35% by weight of the total solution may be present in the emulsion concentrate in any amount. It (as a 35% active solution) may be preferred that cationic surfactant is present in an amount of about 20% to about 50%, about 20% to about 45%, about 30% to about 40% and about 35%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation). In some embodiments the cationic surfactant (as a 35% active solution) is present in an amount of about 30%, about 32%, about 35%, about 37%, about 40%, about 42%, about 45%, about 48%, each by weight of the total emulsion concentrate (prior to any dilution for a pumpable form or dispersion for an end use dispersion formulation).

[0033] Other additives may be included in the emulsion concentrate, and selection and inclusion of these ingredients will vary, depending on the end use of the emulsion concentrate, e.g. , in a personal care formulation versus use as a pesticide or fertilizer dispersant. Exemplary additives may include preservatives, bacteriostatic materials, microbiostatic materials (e.g. , directed to, at minimum, molds and yeasts), bactericides or antibacterial materials, antimicrobial materials, hydroxamic acids, colorants, flavorants, fragrances, pharmaceuticals, biologies, particulates (e.g. , glitter, pearlescents, talc), smectite, additional types of surfactant, an opacifier, a wax, additional types of emulsifier, a fat, a UV absorbing compound, a detergent, foaming agents, stabilizers, pH modifiers, foaming agents, moisturizers, water, an alcohol, chelators, glycerin, a urea, a cosmetic active, a pigment, a wetting agent, a skin or hair conditioner, zinc oxide and the like.

[0034] The emulsion concentrate may be used to prepare "end use dispersion formations", that is, one may disperse the emulation concentrate in a carrier where it forms

microemulsions. The carrier is preferable aqueous or alcoholic-aqueous. Plain water, floral waters or aqueous or hydrogly colic plant extracts may be preferred. Such end use formulations may take the form of numerous and varied products, depending on the presence or absence of other actives/additives to the carrier or to the emulsion concentrate (prior to dispersion). As an example, cosmetic (e.g., decorative elements like glitter or pigment) or active agents (e.g. , pharmaceuticals (regulated and OTC), such as fluoride, hydrocortisone, salicylic acid, or pesticides or bleach) can be delivered to a surface by including them in the emulsion concentrate. When the microemulsions are formed, they are already 'loaded' with the active. As the end use dispersion formulation is applied to a surface, the microemulsion is also delivered to the surface. Actives may also include those additives mentioned above, and any used in personal care and cosmetic applications, such as actives that moisturize, whiten, lighten, brighten, cleanse, or provide skin glow, peptides, anti-aging actives and the like.

[0035] The emulsion concentrate, when dispersed in an end use dispersion formulation, may provide microemulsion particles having an average particle size of about 0.5 to about 10 microns, with about 1 to 5 microns or 1 to 2 microns being preferred in many embodiments.

[0036] The emulsion concentrate of the invention is advantageously cold processable, that is, it can be dispersed in "cold" water - - water that is at about 10°C to 25°C ~ without the need to apply heat to the dispersion process.

[0037] The emulsion concentrate may be prepared as is known or developed in the art. Preferred methods of preparation include those explained in detailed in the Examples, infra. The emulsion concentrate is prepared in the form of a paste or in the form of a pumpable composition. By "pumpable", it is meant that the emulsion concentrate prior to end use dilution is sufficiently flowable that it is capable of being transmitted from a holding reservoir to a mixing container via an ordinary commercial grade pump. Generally, in the preparation of the paste or the pumpable version, the ester oil, nonionic ester emulsifier, and waxy ester are measured out in predetermined amounts, charged to a reactor and heated to about 85°C to 200°C.

[0038] The aqueous cationic surfactant (in a predetermined amount) is pre-heated to about the same temperature, then added to the reactor. The temperature is held and vigorous mixing is applied. The mixture may then be cooled and packed.

[0039] Within the scope of the invention is the emulsion in non-concentrated or semi- concentrated form. For example, it may be diluted with another carrier or substance, such as water or an alcohol or a mixture of the same.

[0040] Also included within the scope of the invention are end use dispersion formulations that are prepared by dispersing the emulsion concentrate (in either paste or pumpable form) in an additional solvent or carrier, preferably an aqueous one. Other additives may be included in the end use dispersion formulation, e.g. , sunscreens, film formers, pigments, pest- or insecticides, pharmaceuticals, botanical extracts, conditioners, etc. End use dispersion formulations may include personal care and cosmetics, agricultural or botanical formulations, medical or veterinary formulations, and/or industrial formulations.

[0041] The emulsion concentrate may be used (either neat in paste or pumpable form or in an end use dispersion formulation) to impregnate a textile. A textile impregnated with the emulsion concentrate can be used to apply the emulsion concentrate or end use dispersion formulation to a surface, such as a surface in a commercial, agricultural/botanical or home environment (plant stem, planter, seed, counter, desk, tables, walls, dishes, toilets, machinery, etc.) or to skin (including mucosal surfaces such as oral mucosa and gingiva), hair or nails (to treat, cleanse, remove make up or pollution deposits, etc.).

[0042] The textile may be any known or to be developed in the art. In some embodiments, it is preferred that the textile is biodegradable, naturally-derived, produced by sustainable and/or 'green methods', and/or flushable. The textile may be woven, nonwoven, or a combination of the same. One-ply or two-ply may be preferred for wipes.

[0043] The textile may include a synthetic or a natural fiber, or a combination or hybrid of the same. Suitable textile materials may include rayon, acetate, polyester, aramid, acrylic, ingeo, olefin, regenerated cellulose, polylactic, bamboo, lotus stem, cotton, banana pseudo stem, pineapple leaves and/or stem, deciduous wood, palm, abaca, coir, jute, flax, kapok, kenaf, hemp, modal, ramie, sisal, soy protein and combinations thereof.

[0044] In one embodiment, the wet wipes are made using biodegradable matrix made of cotton fibers. In another embodiment, the wipe matrix could be made up of manmade fibers (ingeo, regenerated cellulose; Viscose, Lyocell) or their blend with natural and synthetic fibers. In a refinement, the biodegradable wipes are made of natural fibers like lotus stem and those sourced from agricultural waste like banana pseudo stem and pineapple leaves/stem that possess better water absorption and strength than commonly used fibers like cotton and regenerated cellulose.

[0045] The textile may be of any dimension; such dimension will vary depending on the end use of the textile. A textile intended for an end use as a baby skin wipe, for example, will likely have a smaller dimension than a wipe that is for use in cleaning the outer surface of an automobile. In some embodiments, the textile may have a dimension that provides an aspect ratio of about 1 : 1.2, about 1 : 1.5, about 1 : 1.7, and about 1 :2.

[0046] In an embodiment, the textile has a dimension selected from about 3 inches by about 5 inches, about 4 inches by about 6 inches, about 5 inches by about 7 inches, about 6 inches by about 8 inches, about 7 inches by about 9 inches, about 10 inches by about 13 inches, and about 12 inches by about 12 inches.

[0047] In the practice of the invention, the textile is impregnated with the emulsion concentrate or with an end used dispersion formulation that contains the concentrate, either during manufacture or by the end user. In some embodiments, the textile is fully saturated with the composition, or is saturated to a level of about 50%, about 60%, about 70%, about 75%, about 80%, about 85%, about 90%, about 95%, and about 100% of the saturation capacity of a matrix of the textile, where "saturation capacity" is the total amount of a liquid that the textile is able to absorb in one instance.

[0048] The textile or textile(s) may be packaged or housed for consumer use using any package or dispenser known to be developed in the art. For example, conventional packing of bags, pods, or boxes may be used. Packaging may be sterile or non-sterile.

[0049] The textile impregnated as described may be used to deliver active agents to inanimate surfaces (e.g., an antibacterial cleaner to a counter surface or sofa cushion), to skin, hair, or nails (e.g., an antifungal agent to nails) and/or to plant or botanical surfaces (e.g. , a nutrient or UV absorbing moiety to a plant leaf surface). A face of the textile is rubbed or wiped on the surface to deliver the active.

[0050] EXAMPLES

[0051] Example 1 ~ Preparation of Exemplary Emulsion Concentrate - Paste Form

[0052] An emulsion concentrate of the invention in paste form was prepared by obtaining and combining the ingredients in the amount shown in the Table 1 below:

Table 1

[0053] Table 1 includes only the ingredients used in the paste form, a concentrated emulsion that can be easily dispersed in the cold water for further applications.

[0054] The paste form was prepared as follows: The first three ingredients of Table 1 were charged to a reactor and heated to 85+°C. The temperature was held until all ingredients are melted and became homogenous.

[0055] Separately, the cocamidopropyl PG-dimonium chloride (with pre-calculated potential water loss*) was heated to 85+°C, and then added into the reactor. The temperature was held at 85+°C and vigorous mixing was applied until emulsion formed and become homogenous.

[0056] The batch was cooled with vigorous mixing. As cooling progressed, the viscosity of the compound increased, from a pumpable viscosity to a paste-like viscosity. Mixing was reduced to a gentle speed and the mixture cooled to about 80 degrees C.

[0057] To verify the quality of the emulsion concentrate, small paste samples were taken from the batch and diluted l Ox with room temperature water. Emulsion was easily dispersible in water with propeller mixing; no waxy materials were observed at the surface of water when all dispersed.

[0058] A portion of the diluted sample was taken and observed under a microscope at 400X magnification. The particle sizes observed were measured to be between 1 to 2 microns.

[0059] The paste was packaged in jars.

* Pre-calculated potential water loss during the whole manufacture process depends on the reactor, it can be routinely determined after a few batches, usually around 5-10% of total amount.

[0060] The finished emulsion concentrate (paste form) had the properties shown in Table A: Table A
