AND METHODS OF MAKING AND USING

CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial Number 62/417,548, filed November 4, 2016, the entire contents of which is herein incorporated by reference.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0002] Not applicable.

FIELD

[0003] The present disclosure generally relates to estolides of vegetable oil alkoxylates and the methods of producing such. In particular, the present disclosure is directed to a method of reacting castor oil and an alkoxylated glycerin via a transesterification reaction to produce an estolide of castor oil alkoxylate. The present disclosure also generally relates to compositions comprising an estolide of castor oil alkoxylate and uses thereof.

BACKGROUND

[0004] Typically, vegetable oil alkoxylates are prepared by direct alkoxylation of one or more vegetable oils using base catalysts. The direct alkoxylation process for producing a vegetable oil alkoxylate general comprises (i) reacting a vegetable oil such as coconut oil or palm kernel oil with methanol using a base catalyst to form a methyl ester and removing the glycerin byproduct, (ii) hydrogenating the methyl ester to form an alcohol, and (iii) reacting the alcohol with ethylene oxide ("EO") and/or propylene oxide ("PO") to make the vegetable oil alkoxylate.

[0005] For example, EP 0586323 discloses a detergent composition comprising mono-, di-, and tri-ester compounds prepared by direct alkoxylation of coconut oil and palm oil.

[0006] Although various references teach the transesterification of vegetable oils and alkoxylated glycerin to form vegetable oil alkoxylates (see, e.g., U.S. RE38,639, US 2012/0016039, US 5,986, 1 17), they fail to teach the presently disclosed and/or claimed estolides of castor oil alkoxylates and the process of producing such.

[0007] It is an object of the present disclosure to provide a composition comprising an estolide of castor oil alkoxylate having improved properties over comparable castor oil based alkoxylates produced via direct alkoxylation. It is also an object of the present disclosure to provide compositions comprising an estolide of castor oil alkoxylate as well as compositions and processes that utilize the estolide of castor oil alkoxylate.

DETAILED DESCRIPTION

[0012] Before explaining at least one embodiment of the present disclosure in detail, it is to be understood that the present disclosure is not limited in its application to the details of construction and the arrangement of components or steps or methodologies set forth in the following description or illustrated in the drawings. The present disclosure is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.

[0013] Unless otherwise defined herein, technical terms used in connection with the present disclosure shall have the meanings that are commonly understood by those having ordinary skill in the art. Further, unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular.

[0014] All patents, published patent applications, and non-patent publications mentioned in the specification are indicative of the level of skill of those skilled in the art to which the present disclosure pertains. All patents, published patent applications, and non-patent publications referenced in any portion of this application are herein expressly incorporated by reference in their entirety to the same extent as if each individual patent or publication was specifically and individually indicated to be incorporated by reference to the extent that they do not contradict the instant disclosure.

[0015] All of the compositions and/or methods disclosed herein can be made and executed without undue experimentation in light of the present disclosure. While the compositions and methods of the present disclosure have been described in terms of preferred embodiments, it will be apparent to those having ordinary skill in the art that variations may be applied to the compositions and/or methods and in the steps or sequences of steps of the methods described herein without departing from the concept, spirit, and scope of the present disclosure. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope, and concept of the present disclosure.

[0016] As utilized in accordance with the present disclosure, the following terms, unless otherwise indicated, shall be understood to have the following meanings.

[0017] The use of the word "a" or "an", when used in conjunction with the term "comprising", "including", "having", or "containing" (or variations of such terms) may mean "one", but it is also consistent with the meaning of "one or more", "at least one", and "one or more than one".

[0018] The use of the term "or" is used to mean "and/or" unless clearly indicated to refer solely to alternatives and only if the alternatives are mutually exclusive.

[0019] Throughout this disclosure, the term "about" is used to indicate that a value includes the inherent variation of error for the quantifying device, mechanism, or method, or the inherent variation that exists among the subject(s) to be measured. For example, but not by way of limitation, when the term "about" is used, the designated value to which it refers may vary by plus or minus ten percent, or nine percent, or eight percent, or seven percent, or six percent, or five percent, or four percent, or three percent, or two percent, or one percent, or one or more fractions therebetween.

[0020] The use of "at least one" will be understood to include one as well as any quantity more than one, including but not limited to, 1 , 2, 3, 4, 5, 10, 15, 20, 30, 40, 50, 100, etc. The term "at least one" may extend up to 100 or 1000 or more depending on the term to which it refers. In addition, the quantities of 100/1000 are not to be considered as limiting since lower or higher limits may also produce satisfactory results.

[0021] In addition, the phrase "at least one of X, Y, and Z" will be understood to include X alone, Y alone, and Z alone, as well as any combination of X, Y, and Z. Likewise, the phrase "at least one of X and Y" will be understood to include X alone, Y alone, as well as any combination of X and Y. Additionally, it is to be understood that the phrase "at least one of" can be used with any number of components and have the similar meanings as set forth above.

[0022] The use of ordinal number terminology (i.e., "first", "second", "third", "fourth", etc.) is solely for the purpose of differentiating between two or more items and, unless otherwise stated, is not meant to imply any sequence or order or importance to one item over another or any order of addition.

[0023] As used herein, the words "comprising" (and any form of comprising, such as "comprise" and "comprises"), "having" (and any form of having, such as "have" and "has"), "including" (and any form of including, such as "includes" and "include") or "containing" (and any form of containing, such as "contains" and "contain") are inclusive or open-ended and do not exclude additional, unrecited elements or method steps.

[0024] The phrases "or combinations thereof" and "and combinations thereof" as used herein refers to all permutations and combinations of the listed items preceding the term. For example, "A, B, C, or combinations thereof" is intended to include at least one of: A, B, C, AB, AC, BC, or ABC and, if order is important in a particular context, also BA, CA, CB, CBA, BCA, ACB, BAC, or CAB. Continuing with this example, expressly included are combinations that contain repeats of one or more items or terms such as BB, AAA, CC, AABB, AACC, ABCCCC, CBBAAA, CABBB, and so forth. The skilled artisan will understand that typically there is no limit on the number of items or terms in any combination, unless otherwise apparent from the context. In the same light, the term "and combinations thereof" when used with the phrase "selected from the group consisting of" refers to all permutations and combinations of the listed items preceding the phrase.

[0025] The phrases "in one embodiment", "in an embodiment", "according to one embodiment", and the like generally mean the particular feature, structure, or characteristic following the phrase is included in at least one embodiment of the present disclosure, and may be included in more than one embodiment of the present disclosure. Importantly, such phrases are non-limiting and do not necessarily refer to the same embodiment but, of course, can refer to one or more preceding and/or succeeding embodiments. For example, in the appended claims, any of the claimed embodiments can be used in any combination.

[0026] As used herein, the terms "% by weight", "wt.%", "weight percent", or "percentage by weight" are used interchangeably and, unless stated otherwise, are based on the total weight of the referenced composition.

[0027] The phrase "substantially free" shall be used herein to mean present in an amount less than 1 weight percent, or less than 0.1 weight percent, or less than 0.01 weight percent based on the total weight of the referenced composition.

[0028] As used herein, the term "alkyl" is inclusive of both straight chain and branched chain groups and of cyclic groups. In some embodiments, the alkyl group may have up to 40 carbons (in some embodiments up to 30, 20, 15, 12, 10, 8, 7, 6, or 5 carbons) unless otherwise specified. Cyclic groups can be monocyclic or polycyclic, and in some embodiments, can have from 3 to 10 carbon atoms.

[0029] The term "estolide", as used herein, is intended to be consistent with the definition commonly accepted in the field. However, if any inconsistencies exist, the terms "estolide" and "estolide of castor oil alkoxylate", as used throughout the present disclosure, are intended to refer to the structure defined by formula (I) and produced by the process disclosed herein.

[0030] The term "pesticide" refers to at least one pesticide selected from the group consisting of a fungicide, insecticide, nematicide, herbicide, a safener, a plant growth regulator and a mixture thereof. In one particular aspect, the pesticide is selected from the group consisting of a fungicide, insecticide, herbicide and a mixture thereof. The person skilled in the art is familiar with such pesticides, which can be found in, for example, the Pesticide Manual, 15th Ed. (201 1 ), The British Crop Protection Council, London.

Lubricating oil concentrates and their components/amounts are described in US 20150051 132, the contents of which is incorporated by reference herein in its entirety. It has been surprisingly found that the composition comprising an estolide represented by formula (I) may act not only as an emulsifier to enable the formation of a stable emulsion after the lubricating oil concentrate has been diluted with water but may also impart lubricity in the concentrate formulation.

[0085] In one aspect, the composition comprising an estolide represented by formula (I) as described herein may be present in the lubricating oil concentrate in an amount of about 1 % by weight to about 90% by weight, based on the total weight of the lubricating oil concentrate. In another aspect, the composition comprising an estolide represented by formula (I) as described herein may be present in the lubricating oil concentrate in an amount of about 2% by weight to about 50% by weight, based on the total weight of the lubricating oil concentrate. In a further aspect, the composition comprising an estolide represented by formula (I) as described herein may be present in the lubricating oil concentrate in an amount of about 3% by weight to about 30% by weight, or in an amount of about 4% by weight to about 25% by weight, or even in an amount of about 5% by weight to about 20% by weight, based on the total weight of the lubricating oil concentrate.

[0086] The lubricating oil concentrate of the present disclosure also includes a base oil. In some aspects, the base oil will have a kinematic viscosity in the range of from about 1 cSt to about 1000 cSt at a temperature of 40°C. In one particular aspect, the base oil is a petroleum-based oil, vegetable oil, animal-derived oil, a synthetic oil or a mixture thereof.

Alkylene oxide polymers and derivatives thereof where terminal hydroxy groups have been modified by esterification, etherification etc. constitute another class of synthetic oils. These are exemplified by poiyoxyalicylene polymers prepared by the polymerization of ethylene oxide or propylene oxide, the aikyl and aryl ethers of these po!yoxyalkyiene polymers such as methyipolyisopropylene glycol ethers, diphenyi and diethyl ethers of polyethylene glycol, and mono and polycarboxyiic esters thereof, for example, the acetic esters, mixed C3-C8 aliphatic acid esters, Ci ₂ ~C ₂ 2 atty acid esters, and C ₃ oxo diester of tetraethyiene glycol. Simple aliphatic ethers may be used as synthetic oils, such as, dioctyi ether, didecyl ether, di(2~etby!bexyl) ether. Other synthetic oils comprise the esters of fatty acids such as ethyl oleate, lauryi hexanoate, and decyi palmitate and the esters of dicarboxylic acids such as phthalic acid, succinic acid, maleic acid, aze!aic acid, sebacic acid, fumaric acid, adipic acid, iinoleic acid dimer, malonic acid, alkyi malonic acids, alkenyl malonic acids with a variety of alcohols, such as butyl alcohol, hexyl alcohol, dodecyl alcohol, 2-ethylhexyi alcohol, ethylene glycol, diethylene glycol monoethyl ether, propylene glycol are also useful.

[0090] In one aspect, the base oil is a mixture of at least two of the oils described above.

[0091] In some aspects, the base oii may be present in the lubricating oii concentrate in an amount of about 0.5% by weight to about 97.5% by weight, based on the total weight of the lubricating oii concentrate. In another aspect, the base oii may be present in the lubricating oil concentrate in an amount of about 5% by weight to about 95% by weight, based on the total weight of the lubricating oil concentrate. In other aspects, the base oii is present in the lubricating oil concentrate in an amount greater than about 40% by weight, based on the total weight of the lubricating oii concentrate. In further aspects, the base oii is present in the lubricating oii concentrate in an amount less than about 40% by weight, based on the total weight of the lubricating oii concentrate. In still other aspects, the base oil is present in the lubricating oil concentrate in an amount of about 30% by weight to about 85% by weight, based on the total weight of the lubricating oil concentrate while in still other aspects, the base oil is present in the lubricating oil concentrate in an amount of about 5% by weight to about 30% by weight, based on the total weight of the lubricating oil concentrate.

[0092] In some aspects, the lubricating oii concentrate may optionally contain one or more additives. Such additives include, but are not limited to, a surfactant such as an anionic surfactant (for e.g. alkali, alkaline earth or ammonium salts of sulfonates, sulfates, phosphates, carboxyiates, and mixtures thereof), a corrosion inhibitor such as alkaline and alkanolamine salts of organic acids, sulfonate, amine, amide, and organic borate compounds, a biocide such as o-phenylphenol, a bactericide, fungicide, aigaecide, colorant, fragrance, chelating agent, pH buffering agent, solubilizer, antioxidant, anti-foam ing agent, extreme pressure agent, water and mixtures thereof.

[0093] The lubricating oil concentrate may be prepared by admixing the composition comprising an estoiide represented by formula (I) as disclosed herein with the base oil and optional additives.

[0094] In some aspects, the lubricating oil concentrate may be used "as-is" while in other aspects the lubricating oil concentrate may be diluted with water, preferably deionized water, or other aqueous solution prior to addition to an aqueous medium. In aspects where the lubricating oil concentrate is used "as is", the base oil is preferably a vegetable oil,

[0095] Surprisingly, it has been found that addition of the lubricating oil concentrate to an aqueous medium produces a stable, low foaming aqueous emulsion. According to some particular aspects, the stable, low foaming aqueous emulsion is obtained by the addition of the lubricating oil concentrate comprising the estoiide represented by formula (I) as disclosed herein and an anionic surfactant to an aqueous medium, preferably deionized water.

[0096] According to one particular aspect, the lubricating component is used "as is" in a lubricating oil formulation to reduce friction and wear in moving machinery.

[0097] According to another particular aspect, the lubricating oil concentrate may be dispersed in an aqueous medium and used for a cutting or grinding process. The lubricating oil concentrate for a cutting or grinding process may be dispersed in an aqueous medium at a concentration of about 5 weight parts to about 20 weight parts of oil concentrate per 100 parts of aqueous medium (for e.g. water or deionized water) and may include the following

Base Oil 5-25

Composition comprising an estolide

5-15

represented by formula (1)

Additive(s) 0-35

In one particular aspect, the lubricating oil concentrate components for use in such a cutting or grinding process may include:

[0098] In yet another aspect, the composition comprising an estolide having the formula (I) of the present disclosure is included in an agrochemical formulation for application onto a target substrate to elicit a chemical or biological effect. In such aspect, the agrochemical formulation comprises (i) a pesticidally effective amount of a pesticide or a mixture of pesticides and (ii) the composition comprising an estolide having a formula (I) as described herein. According to some aspects, the composition comprising an estolide having the formula (I) is present in the agrochemical formulation at a concentration such that the pesticidal efficacy of the agrochemical formulation is enhanced as compared to a reference agrochemical formulation devoid of the composition comprising an estolide having the formula (I) but otherwise having the same ingredients as the agrochemical formulation. By "enhanced" it is to be understood that the composition comprising an estolide having the formula (I) of the present disclosure increases the performance of the active ingredients in agrochemical formulations (for e.g., a higher activity of the active ingredients for a given application rate, a lower application rate with a given effect, better uptake of the active ingredient by the target substrate, and thus advantages for a pre-emergence or post-emergence treatment, in particular the spray treatment of target substrates) as compared to agrochemical formulations that do not contain an estolide having the formula (I) of the present disclosure.

[0099] In some aspects, the composition useful in agrochemical formulations may consist of the estolide represented by formula (I) while in other aspects the composition may comprise the estolide represented by formula (I) and an auxiliary component.

[0100] Examples of auxiliary components include, but are not limited to, a solvent, liquid carrier, solid carrier or filler, anionic surfactant (for e.g. alkali, alkaline earth or ammonium salts of sulfonates, sulfates, phosphates, carboxylates, and mixtures thereof), nonionic surfactant (for e.g. alkoxylates, N-substituted fatty acid amides, amine oxides, esters, sugar-based surfactants, polymeric surfactants, and mixtures thereof), cationic surfactant (for e.g. quaternary ammonium compounds with one or two hydrophobic groups, or salts of long-chain primary amines), dispersant, emulsifier, wetter, adjuvant, solubilizer, penetration enhancer, protective colloid, adhesion agent, thickener, humectant, repellent, attractant, feeding stimulant, compatibilizer, bactericide, anti-freezing agent, crystallization inhibitor, anti-foam ing agent, colorant, tackifier, binder, preservative, inorganic or organic acid to neutralize the pH, clarifier, stabilizer, fertilizer such as ammonium sulfate, urea or compound fertilizer, such as phosphorus-, potash- and nitrogen-based compound fertilizers (for e.g. Ρ,Κ,Ν fertilizers), UV stabilizer and mixtures thereof.

[0101] According to some aspects, the composition useful in agrochemical formulations may include (i) about 0.1 -99.9% by weight of an estolide represented by formula (I) and (ii) about 0.1 -99.9% by weight of an auxiliary component, where the % by weight is based on the total weight of the composition. In another aspect, the composition may include (i) about 0.1 -50% by weight of an estolide represented by formula (I) and (ii) about 0.1 -50% by weight of the auxiliary component, where the % by weight is based on the total weight of the composition. In yet a further aspect, the composition may include (i) about 0.1 -29.9% by weight of an estolide represented by formula (I) and (ii) about 70.1 -99.9% by weight of an auxiliary component, where the % by weight is based on the total weight of the composition.

[0102] As described above, the composition comprising an estolide represented by formula (I) of the present disclosure enhances the bioactivity of a pesticide, thus the composition is a composition wherein, when combined with a pesticide or mixture of pesticides to form an agrochemical formulation and applied to a target substrate, achieves at least 60%, 65%, 70%, 75%, 80%, or even at least 85%, or even at least 90% control. "% control," as used herein, refers to any observable measure of control of target substrate growth, which can include one or more of the actions of (1 ) killing, (2) inhibiting growth, reproduction or proliferation, and (3) removing, destroying, or otherwise diminishing the occurrence and activity of pests. Control can be measured by any of the various methods known in the art.

[0103] Accordingly, in another aspect, there is provided an agrochemical formulation comprising a pesticide and the composition comprising an estolide represented by formula (I) of the present disclosure (and optional auxiliary component(s)). The agrochemical formulation may be used in treating target substrates, such as those disclosed above, and refers to all forms of compositions including concentrates and spray formulations. "Spray formulations" are aqueous agrochemical formulations including all the components which it is desired to apply to the target substrate or their environment in a form and at a concentration (dilution) appropriate for spraying. Spray formulations can be made up by simple dilution of concentrates containing desired components (other than water), or by mixing of the individual components, or a combination of diluting a concentrate and adding further individual components or mixtures of components. Typically such end use mixing is carried out in the spray tank from which the formulation is sprayed or a holding tank for filling the spray tank and commonly such mixing and mixtures are called tank mixing and tank mixtures. "Concentrates" are agrochemical formulations, which may be aqueous or nonaqueous, and which are designed to be diluted with water (or a water based liquid) to form the corresponding spray formulations and include such compositions in liquid form such as solutions, emulsions or dispersions and in solid form, especially in water dispersible solid form, such as granules or powders. "Emulsifiable concentrates" are liquid "concentrates" including the pesticide and composition comprising an estolide represented by formula (I) in solution or dispersion, usually also including an emulsifier and/or surfactant, which readily emulsify on dilution in water, typically with no more than gentle stirring.

[0104] The amount of pesticide included in the agrochemical formulation of the present disclosure will vary according to a number of parameters, such as the target substrate to be treated, the area to be treated, etc. In general, a rate of application from about five grams to about four kilograms per hectare (g/ha) of pesticide may be suitable. The amount of the composition comprising an estolide represented by formula (I) in the agrochemical formulation may be from about 0.01 -99% by weight, based on the total weight of the agrochemical formulation.

[0105] The agrochemical formulations of the present disclosure may be used in conventional agricultural methods. For example, the pesticide or mixture of pesticides and composition comprising an estolide represented by formula (I) may be mixed with water and/or other solvent(s) and/or fertilizers and applied post-emergence to a desired target substrate by any means, such as airplane spray tanks, knapsack spray tanks, cattle dipping vats, farm equipment used in ground spraying (for e.g., boom sprayers, hand sprayers), and the like.

[0106] As discussed above, in accordance with some aspects, the agrochemical formulation can be a concentrate composition, which can be diluted in a suitable volume of water to form a spray formulation (for e.g., a tank mix composition) for applying to the target substrate. The concentrate composition can be in liquid, solid, or semi-solid form. In at least one aspect, it is an aqueous concentrate composition.

[0107] In one particular aspect, the amount of the pesticide in the concentrate composition can be from about 1 % by weight to about 80% by weight, alternatively from about 16% by weight to about 60% by weight, alternatively from 35% by weight to about 55% by weight, based on the total weight of the concentrate composition. The amount of the composition comprising an estolide represented by formula (I) in the concentrate composition may be from about 0.0001 % by weight to about 20% by weight, alternatively between from about 0.001 % by weight to about 15% by weight, or alternatively from about 0.01 % by weight to about 10% by weight percent, or alternatively from about 0.1 % by weight to about 5% by weight, or even alternatively from about 0.5% by weight to about 3% by weight, based on the total weight of the concentrate composition.

[0108] The concentrate composition can be diluted by a user with water to render a spray formulation containing from about 0.01 % by weight to about 15% by weight, alternatively from about 0.1 % by weight to about 5% by weight, alternatively from about 0.2% by weight to about 2% by weight of the pesticide, based on the total weight of the spray formulation. The spray formulation can typically contain from about 0.0001 % by weight to about 3% by weight, alternatively from about 0.001 % by weight to about 1 % by weight, alternatively from about 0.01 % by weight to about 0.5% by weight percent of the composition comprising an estolide represented by formula (I) of the present disclosure.

[0109] In other aspects of the present disclosure, the pesticide and composition comprising an estolide represented by formula (I) are combined to form a "ready-to-use" (RTU) spray formulation. The RTU spray formulation can be prepared by a user by diluting a concentrate composition as described above, or alternatively can be provided to the user as is. For example, the RTU spray formulation can contain from about 0.5% by weight to about 5% by weight, alternatively from about 0.75% by weight to about 3% by weight, alternatively from about 1 .5% by weight to about 2.5% by weight of the pesticide, based on the total weight of the RTU spray formulation. The RTU spray formulation can contain from about 0.01 % by weight to about 2.5% by weight, alternatively from about 0.2% by weight to about 2% by weight, alternatively from about 0.5% by weight to about 1 % by weight of the composition comprising an estolide represented by formula (I) of the present disclosure. The balance of the RTU composition can be water.

[0110] In still yet another aspect, there is provided a method for killing or inhibiting or repelling a pest comprising the steps of providing an agrochemical formulation comprising (i) a pesticidally effective amount of a pesticide and (ii) a composition comprising an estolide represented by formula (I) of the present disclosure and optional auxiliary component(s) and contacting the agrochemical formulation and the pest. [0111] Examples are provided below. However, the present disclosure is to be understood to not be limited in its application to the specific experiments, results, and laboratory procedures disclosed herein below. Rather, the Examples are simply provided as one of various embodiments and are meant to be exemplary and not exhaustive.

Improved Interfacial Tension, Foaming, and Surfactancy Properties

[0112] To illustrate the improved properties of the presently disclosed estolides of castor oil alkoxylates, three different estolide compositions were prepared from ethoxylated glycerin having either 10 moles, 15 moles, or 25 moles of ethoxylation, and were compared to alkoxylates produced via direct alkoxylation of castor oil and ethoxylated glycerin having 10 moles, 15 moles, and 25 moles of ethoxylation.

[0113] It should be noted that the number of moles of alkoxylation (e.g., 10 moles of ethoxylation) for alkoxylated glycerin refers to the number of stoichiometric equivalents of alkylene oxide added to one stoichiometric equivalent of glycerin. That is, for formula (II) disclosed herein, the number of moles of alkoxylation equals the sum of "x", "y", and "z". The same applies for formula (I) disclosed herein. For instance, an ethoxylated glycerin having 10 moles of ethoxylation can be represented by formula (II), wherein R' is hydrogen and the sum of x, y, and z is 10. A person of ordinary skill in the art will understand that x, y, and z do not necessarily have to be equal.

Estolide Compositions

[0114] To make the estolide compositions, three ethoxylated glycerin compositions were first produced having 10 moles, 15 moles, and 25 moles of ethoxylation. In order to clarify the process, only the procedure for producing estolides from 10 mole-ethoxylated glycerin will be set out below. A person of ordinary skill in the art will readily recognize the steps necessary to increase the moles of ethoxylation to 15 and 25.

[0115] The ethoxylated glycerin having 10 moles of ethoxylation was produced by charging 17.23 parts (weight percent) glycerin and 0.22 parts 45% potassium hydroxide (commercially available from Ashta Chemicals, Inc. (Ashtabula, OH)) into a clean, dry nitrogen purged reactor and heated at 100 to 1 15°C for nitrogen stripping until water was present at 0.05 wt.% or less. The vessel was then heated to 145°C. Thereafter, 82.44 parts ethylene oxide was charged and reacted at 155 to 165°C and less than 60 psig until the pressure change was less than 0.5 psig over a thirty minute period. The reactor was slowly vented and nitrogen stripped for 90 minutes at 120°C. Samples of the product were analyzed for hydroxyl number to determine if the target amount of ethoxylation was reached and corrections were made as necessary. Once the hydroxyl number was achieved, the reaction was cooled to 95°C and 0.1 parts acetic acid were charged incrementally. The reaction product was mixed for 20 minutes and then used in an esterification reaction with castor oil.

[0116] The esterification reaction was carried out by adding 29.5 parts (weight percent) of the 10 mole ethoxylated glycerin described above with 0.6 parts 45% potassium hydroxide in a round bottom flask equipped with a heating mantle, thermocouple, overhead stirring, and nitrogen inlet. The composition was mixed while heating at 140°C until the amount of water therein was less than 0.1 %. The reaction was then cooled to 120°C and 68.9 parts castor oil (commercially available from Acme- Hardesty Co. (Blue Bell, PA)) was slowly added into the flask over 60 minutes. The reaction was allowed to digest for 15 minutes before adding 1 part hydrogen peroxide to bleach the material.

Comparative Direct Alkoxylation Compositions

[0117] The comparative direct alkoxylation example having 10 moles of ethoxylation was prepared by charging 67.4 parts (weight %) of castor oil and 0.23 parts 45% potassium hydroxide to a clean, dry, nitrogen purged reactor. The material was heated to a range of 120°C to 127°C and dried under vacuum until the water content was less than 0.05%. After stripping, temperature was increased to 135°C to 146°C and 19 parts of ethylene oxide was added. The material was allowed to digest at 160°C until a pressure drop less than 1 psig was recorded over a 30 minute period. Once the pressure drop was stabilized, the material was neutralized with glacial acetic acid.

[0118] The same procedure was followed for the comparative direct alkoxylation examples having 15 moles and 25 moles of ethoxylation.

[0119] Three separate tests were performed to analyze the properties of the estolides as compared to the compositions prepared via direct alkoxylation. [0120] Interfacial tension: The interfacial tensions of the estolide examples and the comparative direct ethoxylation examples were tested using a KRLJSS DVT50 drop volume tensiometer (Kruss GmbH of Hamburg, Germany) to test their interfacial tension with olive oil.

[0121] The interfacial tension results are illustrated in FIG. 2, wherein lower interfacial tension values are preferred. As can be seen in FIG. 2, the comparative direct ethoxylation examples had significantly higher interfacial tension between 10 and 25 moles of ethoxylation when compared to the estolide examples.

[0122] Foaming: The foaming properties of the estolide examples and the comparative direct ethoxylation examples were tested by individually adding 200 ml_ samples of each to a Waring blender and then mixing for 10 seconds on maximum speed. Each mixed sample was then poured into separate graduated cylinders. The foam heights were measured initially and then once again after five minutes.

[0123] The foaming properties for the estolide examples and the comparative direct ethoxylation examples are illustrated in FIG. 3, wherein the larger foam height values demonstrate better foaming properties. As can be seen in FIG. 3, the estolide examples had significantly better foam height than the comparative direct ethoxylation examples.

[0124] Surfactancy: The surfactancy (i.e., the efficiency of a wetting agent) was tested using the Draves Wetting Test following ASTM D2281 where a cotton skein was dropped into a graduated cylinder containing a surfactant solution the estolide or comparative compositions. The time required for the string connecting to the sinker and the skein to relax is recorded as the wetting time.

[0125] The surfactancy of the estolide examples and the comparative direct ethoxylation examples are illustrated in FIG. 4, wherein lower wetting times suggest better surfactancy. As can be seen in FIG. 4, the surfactancy (or wetting time) of the estolide examples were better than the comparative direct ethoxylation examples between 10 moles and 25 moles of ethoxylation.

Mortar Flow Test

[0126] A mortar flow test according to ASTM C1437 and a mortar slump test according to ASTM C143 were also performed using a mortar comprising: a) 450g Type I Portland Cement from Lafarge, b)1350g ASTM c778 test sand form local natural silica suppliers, c) Sodium Montmorillonite from Sigma Aldrich, with a measured surface area of 58m ² /g, d) MIGHTY 21 ES from Kao Chemical as the polycarboxylic ether (PCE), e) distilled water, and f) a clay mitigating agent (CMA) selected from either an estolide of castor oil alkoxylate or a comparative example prepared by direct alkoxylation of castor oil.

[0127] The mixture design was set to be 41 % water to cement ratio, 0.14% PCE to cement ratio, 0.08% of the clay mitigating agent to cement ratio, and 0.5% clay to sand ratio. Two drops of SURFONIC® LF68 defoamer (commercially available from Huntsman Petrochemical LLC, Woodlands, TX) were also added to the composition as an anti-foam ing agent.

[0128] The comparative example was prepared as set forth above for the comparative direct alkoxylation example having 10 moles of ethoxylation.

[0129] The estolide of alkoxylated castor oil was prepared as set forth above for the estolides produced from 10 mole-ethoxylated glycerin.

[0130] The following tables (Tables 1 - 3) illustrate the slump, flow, and workability of the above-described mortar when 1 ) not including any clay mitigation agents, 2) including the above-described comparative example prepared by direct alkoxylation as a mitigating agent, and 3) including the above-described estolide of castor oil ethoxylate as a mitigating agent. The workability value - as used herein - is the value of "slump + flow - 100".

Table 1

Castor Oil Direct Ethoxylation 78 62 52

Estolide of Castor Oil Ethoxylate 80 77 68

Table 2

Estolide of Castor Oil Ethoxylate 138 134 130

Table 3

[0131] The reference sample in Table 1 shows the flow of the mortar without any clay mitigating agents. It is seen that due to the presence of clay in the formula, the flowability of the mortar dropped quickly within 30 minutes of observation. After adding the above-noted CMAs to the mortar, the flow was improved for the estolide example at 9 minutes, and significantly improved for the estolide example after 30 and 60 minutes, and the mortar remained flowable throughout the whole 60-minuite observation period.

[0132] The slump life of the mortar was also significantly prolonged by the above- mentioned estolide example. As seen in Table 2 the slump value was improved by the castor oil direct alkoxylation example but was greatly improved by the estolide example over time.

[0133] Table 3 indicates the overall workability was improved from 9 minutes to 60 minutes by the estolide example. The estolide of castor oil alkoxylate showed much greater capacity than the castor oil direct alkoxylation molecules in promoting good slump/flowability/workability in the mortar containing clay-contaminated sand.

Pigment Dispersion Test

[0134] A pigment dispersion test was also performed using an estolide of castor oil alkoxylate as a dispersant. For comparison, the following compositions were also used as dispersants: 1 ) a castor oil alkoxylate produced by direct alkoxylation of castor oil, 2) a soybean oil ethoxylated glycerin produced by transesterification of soybean oil and ethoxylated glycerin (10 moles of ethoxylation) at a weight ratio of 30:70 soybean oil to ethoxylated glycerin, and 3) soybean oil ethoxylated glycerin (25 moles of ethoxylation) having a weight ratio of 30:70 of soybean oil to ethoxylated glycerin.

[0135] The dispersants were prepared using the following procedures:

[0136] The estolide of alkoxylated castor oil was prepared as set forth above for the estolides produced from 10 mole-ethoxylated glycerin.

[0137] The comparative example was prepared as set forth above for the comparative direct alkoxylation example having 10 moles of ethoxylation.

[0138] The soybean oil alkoxylated glycerin samples were prepared exactly the same as the estolide of alkoxylated castor oil using ethoxylated glycerin having 10 moles of ethoxylation and 25 moles of ethoxylation. However, the process did not produce estolides of the soybean oil alkoxylated glycerin.

[0139] Additionally, a reference dispersant was used. The reference dispersant was a leading commercial pigment dispersant, DISPERBYK® 190 dispersant, available from BYK Additives & Instruments (Wesel, Germany).

[0140] In order to test the impact of the dispersants on pigment dispersion, the dispersants were individually combined with 25% pigment (blue pigment PB 15:4 commercially available from Heliogen Blue L7101 F, BASF) and water in speedmixer™ cups (commercially available from Flacktek, Landrum, South Carolina; USA). The loading was controlled at 1 : 10 active dispersant to pigment mass ratio.

[0141] The mixtures were then pre-mixed in a speedmixer™ for 30 seconds and then milled with 2mm glass beads at 3000 rpm for 3min. The supernatant colorant was set at about 20 to 25°C overnight, and was used to tint a base paint (i.e., PPG Olympic One Interior Semi-Gloss Enamel(Base 1 -356824) at 3 wt.% of the loading in the base paint.

[0142] The tinted compositions were then letdown on a BYK BYKO coating char with a 4 mm BYK-Gardner drawdown bar. After the films dried, a BYK-Gardner spectrometer was used to evaluate their color (tint) strength.

[0143] The results of the color (tint) strength test are set forth in Table 4.

Table 4

[0144] Table 4 illustrates that vegetable oil alkoxylate chemistry, specifically estolides of castor oil alkoxylate, enable acceptable flowability and tinting power for the blue pigment PB 15:4 in water and in base paints. As shown in Table 4, the reference dispersant is the commercial standard and the color strength is within at least 10% of the commercial standard when using the estolide of castor oil alkoxylate described herein.

[0145] From the above description, it is clear that the present disclosure is well adapted to carry out the object and to attain the advantages mentioned herein as well as those inherent in the present disclosure. While exemplary embodiments of the present disclosure have been described for the purposes of the disclosure, it will be understood that numerous changes may be made which will readily suggest themselves to those skilled in the art which can be accomplished without departing from the scope of the present disclosure and the appended claims.
