Description

Surfactants used in inks, coatings, and adhesives

[0001] Cross-reference to related applications This application claims priority to U.S. Patent Application No. 18 / 795,167, filed August 5, 2024, which claims priority to U.S. Provisional Patent Application No. 63 / 531,200, filed August 7, 2023, the entire disclosure of which is incorporated herein by reference. Technical Field

[0002] This disclosure relates to surfactants for use in inks, coatings, and adhesives. Such surfactants may comprise siloxane derivatives of amino acids, wherein the siloxane derivatives have surface-active properties. Background Technology

[0003] Surfactants (molecules with surface-active properties) are widely used in commercial formulations of inks, coatings, adhesives, and paint removers. Surfactants can be included as emulsifiers, wetting agents, foaming agents, dispersants, and / or agents that improve spreadability.

[0004] Surfactants can be uncharged, amphoteric, cationic, or anionic. Although in principle any class of surfactant (e.g., cationic, anionic, nonionic, amphoteric) is applicable, formulations may contain combinations of two or more surfactants from two or more surfactant classes.

[0005] Typically, surfactants are amphiphilic molecules with a relatively water-insoluble hydrophobic "tail" group and a relatively water-soluble hydrophilic "head" group. These compounds can adsorb at interfaces, such as between two liquids, a liquid and a gas, or a liquid and a solid. In systems containing relatively polar and relatively nonpolar components, the hydrophobic tail preferentially interacts with one or more of the relatively nonpolar components, while the hydrophilic head preferentially interacts with one or more of the relatively polar components. In the case of a water-oil interface, the hydrophilic head group preferentially extends into the water, while the hydrophobic tail preferentially extends into the oil. When added to a water-gas interface, the hydrophilic head group preferentially extends into the water, while the hydrophobic tail preferentially extends into the gas. The presence of surfactants disrupts at least some of the intermolecular interactions between water molecules, replacing at least some of the normally weaker interactions between water molecules and the surfactant. This results in a reduction in surface tension and can also be used to stabilize interfaces.

[0006] At sufficiently high concentrations, surfactants can form aggregates that confine the hydrophobic tails to the polar solvent. One such aggregate is a micelle. In a typical micelle, molecules are arranged in a sphere, with the hydrophobic tails of one or more surfactants preferably located within the sphere, and the hydrophilic heads of one or more surfactants preferably located on the outside of the micelle, where the heads preferably interact with the more polar solvent. The effect of the given compound on surface tension and its concentration at which micelles form can serve as a defining characteristic of the surfactant. Summary of the Invention

The amino acids can be functionalized with different types of siloxane groups to form compounds with surface-active properties. Characteristically, these compounds may have a low critical micelle concentration (CMC) and / or the ability to reduce the surface tension of liquids.

[0041] The phrase “within any range using these endpoints” as used in this article literally means any range of values ​​that can be selected from any two values ​​listed before this phrase, whether those values ​​are in the lower or higher part of the list. For example, a pair of values ​​can be selected from two lower values, two higher values, or a lower value and a higher value.

[0042] As used in this article, the term "alkyl" refers to any saturated carbon chain, which can be straight or branched, and can be substituted at any position along the carbon chain. The carbon chain can have 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 carbons.

[0043] As used herein, the phrase "surfactant" refers to the ability of a compound to reduce the surface tension of the medium in which it is at least partially dissolved and / or the interfacial tension with other phases, and thus to be at least partially adsorbed at liquid / vapor and / or other interfaces. The term "surfactant" can be applied to such compounds.

[0044] Regarding the terminology of imprecision, the terms "approximately" and "roughly" are used interchangeably to refer to a measurement that includes the measured value and any measurement that is substantially close to the measured value. As understood and readily determined by one of ordinary skill in the art, a measurement that is substantially close to the measured value differs from the measured value by a considerably small amount. Such deviations may be attributed to measurement errors or minor adjustments made to optimize performance. In cases where the value of such a considerably small difference would not be readily discernible to one of ordinary skill in the art, the terms "approximately" and "roughly" can be understood to mean ±15% of the value, such as ±15%, ±12%, ±10%, ±9%, ±8%, ±8%, ±7%, ±6%, ±5%, ±4%, ±3%, ±2%, or even ±1%, etc.

[0045] This disclosure provides formulations of inks, coatings, adhesives, and paint removers.

[0046] I. Several reasons have made inkjet printing a popular method for recording images on various media surfaces, especially paper. Some of these reasons include low printer noise, high-speed recording capabilities, high quality, and multi-color recording. Additionally, these advantages are available to consumers at a relatively low price. However, despite significant improvements in inkjet printing, consumer demands in this field are increasing, such as higher speeds, higher resolution, full-color image formation, increased stability, and more durable images.

[0047] Inkjet ink kits are used in color inkjet printing systems. An ink kit typically includes multiple inks of different colors, usually in sets of four, six, or eight colors (e.g., one or more shades of cyan, magenta, yellow, and / or black), and may also include image fixing / fixer fluid. Fixer fluid is typically applied before or after the inks are applied to the surface of the printing media. Fixer fluid is a substantially colorless liquid that interacts with the colorant and / or polymer components of one or more inks, thereby depositing or otherwise fixing one or more inks onto the surface of the printing media.

[0048] The precipitated colorant deposits on the surface of the medium, resulting in enhanced image quality properties such as optical density and chromaticity. Durability properties such as water resistance and highlighter stain resistance also benefit from this active ink chemistry. Although several suitable ink kits including fixer are currently available, improvements are expected to formulate more durable and reliable inks that will produce higher quality printed images on the surface of the printing medium without damaging the printhead containing it. Unbound by any theory, it is believed that after the fixer composition is overprinted with the inkjet ink composition onto the substrate, or in other words, when the ink and fixer meet on the medium surface, a very efficient collision of ink colorants is achieved, and almost all the colorant is deposited on the surface of the medium, rather than penetrating the medium and depositing below the surface. Simultaneously, the fixer carrier becomes highly wetted after mixing with the ink carrier, and the mixed carrier rapidly penetrates the medium, leaving the colorant behind.

[0049] In this inkjet printing method, the combination of fixer and inkjet ink composition produces a system and method that provides high-quality and durable inkjet image printing. The use of the fixer disclosed herein results in enhanced image quality properties such as optical density, chromaticity, and durability. Furthermore, when used in an inkjet printing system, the fixer composition provides good image quality without adversely affecting the reliability of the inkjet structure. In fact, it has been found that the fixer does not damage the printhead containing it and exhibits low corrosivity to the inkjet system and inkjet pen.

[0050] The ink formulation disclosed herein comprises an inkjet fixing composition comprising one or more surfactants selected from one or more surfactant classes, one or more wetting agents, a metal carboxylate as a fixing agent, and an acid, based on adjusting the pH of the composition to about 5.0 to about 7.0. The formulation may also be an aqueous carrier and one or more colorants dispersed in the ink carrier.

[0051] 1. Surfactants The ink formulations of this disclosure comprise one or more surfactants, also referred to as surfactant systems. Surfactants have an excellent ability to maintain surface tension and interfacial tension at appropriate levels. Surfactants can also be used as wetting agents and dispersants. Suitable surfactants for use in the ink formulations of this disclosure comprise one or more surfactants of formula I or II and / or co-surfactants. Formula I Equation II, where R 1 and R 2They may be the same or different, and contain at least one group selected from C1-C6 alkyl groups. Optionally, the C1-C6 alkyl groups may include one or more oxygen, nitrogen, or sulfur atoms or groups containing at least one of these atoms, and the alkyl chain may optionally be substituted by one or more substituents selected from hydroxyl, amino, amide, sulfonyl, sulfonate, carbonyl, carboxyl, and carboxylic acid esters; R 3 Selectable from alkenyl, alkynyl, ester, alcohol, arylalkyl, alkoxyalkyl ether, alkyl phosphate, alkyl phosphonate, C3-C8 carboxylic acid, C1-C 10 Alkylbenzoic acid and C1-C 12 Connecting base, the C1-C 12 The linker is connected to another surfactant molecule having the structure shown in Formula I, wherein the other surfactant molecule of Formula I may be the same as or different from the surfactant molecule of Formula I; n and z may be independently selected from any integer from 1 to 12; m may be any integer from 1 to 12; and X may be selected from chloride ions, bromide ions, and iodide ions.

[0052] Specifically, R 3 Optional from C2-C 10 alkenyl, C2-C 10 alkynyl group, C2-C 12 Ester, C1-C 10 Hydroxyl, benzyl, C2-C 12 Alkoxyalkyl ethers, alkyl phosphates, alkyl phosphonates, C3-C8 carboxylic acids, C1-C5 alkylbenzoic acids, and three-carbon linkages attached to the second molecule of Formula I, wherein the second molecule of Formula I is identical to the first molecule of Formula I.

[0053] More specifically, R 3 The following formula can be selected: .

[0054] In particular, suitable surfactants or co-surfactants may include any one of the surfactants 1-12 described herein.

[0055] The amount of surfactant system in the ink formulation, based on the weight of the composition, may be in the range of about 0% by weight or more, about 0.1% by weight or more, about 0.2% by weight or more, about 0.4% by weight or more, about 0.6% by weight or more, about 0.8% by weight or more, or about 1.0% by weight or less, about 1.2% by weight or less, about 1.4% by weight or less, about 1.6% by weight or less, about 1.8% by weight or less, or about 2.0% by weight or less, or in any range from 0% by weight to 2% by weight, or from 0.1% by weight to 1.8% by weight, or from 0.2% by weight to 1.6% by weight, or from 0.4% by weight to 1.4% by weight, or from 1.0% by weight to 1.2% by weight, or in any range using any two of the foregoing values.

[0056] 2. Wetting Agent The ink formulations disclosed herein contain a wetting agent. "Wetting agent" herein refers to any substance used as a wetting agent or humectant. Without any theoretical connection, the wetting agent maintains the water content of the fixer within a narrow range, independent of humidity fluctuations, and is therefore typically added to prevent clogging of narrow inkjet pen nozzles.

[0057] Wetting agents are high-boiling-point water-miscible organic compounds, such as polyols, amides, or polyethers. Wetting agents can be water-soluble. Suitable water-soluble wetting agents for this purpose include, but are not limited to, heterocyclic ketones (e.g., 2-pyrrolidone, N-methylpyrrolidone-2-one, 1,3-dimethylimidazolidine-2-one, octylpyrrolidone, etc.); diols (e.g., ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, polyethylene glycol, polypropylene glycol, etc.); glycerol; and diols (e.g., butanediol, pentanediol, hexanediol, etc.).

[0058] The wetting agent may be present in the ink formulation in an amount of about 1% or more, 2% or more, 5% or more, 8% or more, or 10% or less, 12% or less, 15% or less, 18% or less, 20% or less, or in any range using these endpoints.

[0059] 3. Fixing fluid, also known as fixing agent, contains an aqueous carrier and an effective amount of one or more fixing agents. A fixing agent is a component that induces a change in the solubility or stability of the colorant and fixes the colorant to the appropriate location in the printed image. The "effective amount" of fixing agent is the amount that effectively improves print quality compared to an unfixed print, such as reduced bleed and show-through, increased optical density (OD), chromaticity, edge sharpness, and improved drip and smear fastness. Fixing fluids can be formulated for high spreadability and rapid penetration and drying. Surface tension can be less than about 45 mN / m.

[0060] Fixing agents can be metal carboxylates, such as metal salts composed of polyvalent metal ions and carboxylate ions.

[0061] Suitable metal carboxylates may include polyvalent metal carboxylates, which contain divalent metal ions such as Ca. 2+ Mg 2 + Cu 2+ and trivalent metal ions such as Al 3+ La 3+ or Fe 3+ .

[0062] Carboxylate ions can be aliphatic monocarboxylic acids with 1-6 carbon atoms. Suitable carboxylate ions include acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, isovaleric acid, neovaleric acid, and hexanoic acid.

[0063] The fixer is present in the fixer composition in amounts of about 3% or more by weight, about 4% or more by weight, about 5% or more by weight, about 6% or more by weight, about 7% or more by weight, about 8% or more by weight, about 9% or more by weight, or about 10% or less by weight, about 11% or less by weight, about 12% or less by weight, about 13% or less by weight, about 14% or less by weight, about 15% or less by weight, about 16% or less by weight, or in any range using these endpoints.

[0064] 4. The acid fixer may include an acid. Any suitable acid may be selected. For example, a strong acid (i.e., an acid that is completely ionized in water) may be added to the fixer composition. Non-limiting examples of such acids include methanesulfonic acid, hydrochloric acid, nitric acid, hydrobromic acid, sulfuric acid, perchloric acid, hydroiodic acid, trifluoroacetic acid, and / or combinations thereof.

[0065] Acids help to adjust the pH of the fixer composition. The pH of the fixer composition can be about 5.0 or greater, about 5.5 or greater, about 6.0 or greater, about 6.5 or less, about 7.0 or less, or in any range using these endpoints.

[0066] In some respects, the fixer formulation will not form or will form less than 0.5% acid vapor (volatile organic acids) after assembly. In other respects, the pH of the fixer solution will be adjusted to a suitable range to avoid the fixer composition containing more than 0.5% by weight of volatile organic acids.

[0067] 5. Aqueous Formulations The fixing solutions disclosed herein may contain an aqueous carrier. As defined herein, the term "aqueous carrier" refers to an aqueous mixture in which the fixing agent is placed to form the fixing solution. Suitable aqueous carrier components may include, but are not limited to, water, cosolvents, surfactants, additives (corrosion inhibitors, salts, etc.), and / or combinations thereof.

[0068] The aqueous carrier may contain a water-soluble organic cosolvent, an additional surfactant, and water. Non-limiting examples of water-soluble organic cosolvents include 2-ethyl-2-hydroxymethyl-1,3-propanediol, glycerol propoxylate, tripropylene glycol, 1-(2-hydroxyethyl)-2-pyrrolidone, 1-(2-hydroxyethyl)-2-imidazolinone, and / or combinations thereof.

[0069] 6. Colorant The inkjet ink kit of this disclosure may include aspects of the fixer composition and an ink having a colorant dispersed or dissolved in an ink carrier. The inkjet ink kit may at least include an inkjet ink composition containing a colorant dispersed in an ink carrier, and a fixer containing one or more surfactants selected from one or more surfactant classes, one or more wetting agents, a metal carboxylate as a fixer, and an acid.

[0070] It should be understood that any number of colored ink compositions may be contained in an ink kit containing a fixer. Furthermore, any desired combination of colored inks may be used. For example, each colored ink composition may be a different color, or two or more inks may be different shades of the same color (i.e., light magenta and dark magenta inks). In some aspects, inkjet ink kits contain four different colors of ink: black ink, yellow ink, cyan ink, and magenta ink. In other aspects, inkjet ink kits contain any desired number of inks selected from black ink, yellow ink, cyan ink, magenta ink, orange ink, red ink, green ink, and / or combinations thereof. In some aspects, inkjet ink kits contain a fixer as described herein and contain inkjet ink compositions selected from black ink, yellow ink, cyan ink, magenta ink, orange ink, red ink, and green ink.

[0071] Each ink contains a colorant selected from pigments, dyes, or combinations thereof. In some embodiments, the ink contains a pigment as a colorant. As used herein, "pigment" refers to colorant particles that are substantially insoluble in the liquid carrier to which they are used. Pigments may be dispersed using a single dispersant or may be self-dispersible, having a dispersant attached to the pigment surface. As used herein, "self-dispersible" generally refers to a pigment that has been functionalized with a dispersant, for example, by chemically attaching the dispersant to the pigment surface. The dispersant may be a small molecule or a polymer or oligomer. Pigments comprise both self-dispersible pigments and dispersed pigments, such as pigments dispersed by a single dispersant non-covalently attached to the surface. In one instance, the pigment is not self-dispersible, and a dispersing aid may be incorporated into the carrier. In another instance, the pigment is self-dispersible and modified to contain at least one polymer chemically attached thereto.

[0072] In the example colorants, the numbers categorize the chemical composition, so "Pigment Blue 29" indicates that it is sodium aluminum sulfosilicate. These numbers are not directly related to any part of the actual chemical structure; rather, they are assigned according to the order in which the pigments were added to the general code of the color index (not according to when the pigments were discovered).

[0073] Colorants for cyan and / or magenta inks can be combinations of pigments and dyes. Pigments and / or dyes for cyan and magenta colorants can be selected from several commercially available pigments and / or dyes. Non-limiting examples of suitable pigments for cyan colorants include Pigment Blue 1, Pigment Blue 2, Pigment Blue 3, Pigment Blue 15:4, Pigment Blue 16, Pigment Blue 22, Pigment Blue 29, Vat Blue 4, Vat Blue 6 and / or similars, and / or combinations thereof.

[0092] II. Coatings This disclosure provides coating formulations, particularly latex compositions or coating carriers for semi-gloss and matte interior coating compositions. Latex coating compositions have captured a significant portion of the interior and exterior coatings market due to several advantages compared to organic solvent-based types.

[0093] The coating formulations disclosed herein may comprise a film-forming agent, a binder, one or more surfactants selected from one or more surfactant classes, one or more desiccants, one or more pigments, one or more solvents, and water.

[0094] 1. Film-forming agents: Film-forming agents are a group of chemicals that leave a soft, cohesive, and continuous coating on a surface. This film is highly hydrophilic. Film-forming agents comprise a large class of chemicals, which can be broadly classified into two categories: natural and synthetic.

[0095] Natural film-forming agents include oils, rosin, carbohydrates, and egg whites. These natural film-forming agents may include cyclic low-terpenes, polyterpenes, and shellac (such as starch, cellulose, etc.).

[0096] Synthetic film-forming agents include condensation polymers, addition polymers, and polymer resins. These agents may include alkyd resins, polyesters, polyamide / imide resins, silicone resins, crosslinking materials such as phenolic resins, melamine resins, urea resins, polyurethanes, epoxy resins, polyolefins, polyethylene resins, and polyacrylic acid resins.

[0097] Latex coatings typically contain synthetic film-forming agents, such as polyacrylate resins and alkyd resins, as discussed further below.

[0098] a. Latex emulsions are commonly used in the formulation of two types of latex coatings: all-acrylic systems, such as those using copolymers of methyl methacrylate, butyl acrylate, 2-ethylhexyl acrylate, and small proportions of acrylic acid (if desired), and vinyl acetate formulations, which are typically combined with small proportions of lower alkyl acrylates such as 2-ethylhexyl acrylate, methyl methacrylate, or butyl acrylate. To date, all-acrylic systems have been used in high-quality coatings due to their good water resistance, desired leveling properties, film hardness, durability, and scrub resistance. Vinyl acetate-acrylic copolymer systems have been used to formulate interior matte and semi-gloss coatings and exterior wall coatings, and vinyl acetate-butyl acrylate latex results in coating films with excellent toughness, scrub resistance, and durability, while vinyl acetate-dibutyl maleate emulsions offer good abrasion resistance, flexibility, and durability.

[0099] By polymerizing wet-adhesion monomers into copolymers, both acrylic and vinyl acetate systems have been endowed with wet adhesion properties—that is, the quality of adhesion to previously coated, aged surfaces under wet or damp conditions. Typically, these monomers have terminal olefinic unsaturation at one end and terminal urea groups or urea functionality at the other. While these monomers improve the ability of emulsions to adhere to previously coated films under wet conditions, they are sometimes difficult to polymerize into systems, especially acrylic systems, and it is difficult to obtain other desired properties in coatings. Therefore, wet adhesion properties are imparted to coating carriers by blending different types of acrylic polymer emulsions to obtain the overall properties required in the coating carrier, such as durability, wet adhesion, scrub resistance, flexibility, good leveling properties, abrasion resistance, and toughness.

[0100] Suitable emulsions include vinyl acetate latex. For indoor and outdoor applications, vinyl acetate can be copolymerized with monomers to which it can be copolymerized, namely, lower alkyl acrylates, such as C1-C6 esters of acrylic acid and methacrylic acid, including methyl methacrylate, ethyl acrylate, butyl acrylate, 2-ethylhexyl acrylate; olefins, such as ethylene; alkyl esters of α-β-unsaturated dicarboxylic acids, such as dibutyl maleate, dibutyl fumarate, dioctyl maleate, dibutyl itaconic acid; vinyl chloride, vinyl esters, such as vinyl butyrate, vinyl propionate; vinyl ethers, such as methyl vinyl ether, n-butyl vinyl ether; and unsaturated carboxylic acids and amides, such as acrylic acid and methacrylic acid, acrylamide and methacrylamide.

[0101] For wet adhesion to be achieved in emulsions, which is necessary in most coating applications, wet adhesion monomers can be copolymerized with vinyl acetate to form vinyl acetate terpolymers. They can also be copolymerized with other monomers and blended with vinyl acetate copolymers to obtain wet adhesion. As used herein, “wet adhesion monomer” should be understood to refer to monomers that have allyl or acrylic unsaturation in one part of the molecule and a side-chain urea or acyclic and cyclic urea functional group at the other end.

[0102] Latex may be present in the formulation in an amount of about 40% by weight or more, about 45% by weight or more, about 50% by weight or more, about 55% by weight or more, or about 60% by weight or less, about 65% by weight or less, about 70% by weight or less, or in any range using these endpoints as a percentage of the total formulation.

[0119] 3. Desiccant Coating Formulations may contain one or more desiccants. A desiccant is a catalyst used to accelerate the drying process. Suitable desiccants may include oxidation catalysts such as cobalt or manganese salts, polymerization catalysts such as zirconium salts, and / or auxiliary catalysts controlling film formation such as calcium salts. The desiccant enables the coating to dry completely within a few hours, such as three hours, two hours, or less, after application to the surface.

[0125] 6. Other additives: Coating formulations may further include one or more additives, such as fillers, pigments, surfactants, stabilizers, thickeners, emulsifiers, texture additives, adhesion promoters, biocides, flow promoters, dispersants, and additives for changing viscosity or finishing appearance.

[0126] The additive may be included in the coating formulation in amounts of about 0.1% by weight or more, about 0.5% by weight or more, about 1.0% by weight or more, about 1.5% by weight or more, or about 2.0% by weight or less, about 5.0% by weight or less, about 10.0% by weight or less, about 20% by weight or less, about 25% by weight or less, about 30% by weight or less, or in any range using these endpoints.

[0128] Coating formulations may contain one or more additives selected from surfactants, stabilizers, thickeners, emulsifiers, texture additives, adhesion promoters, biocides, and additives used to change viscosity or finish appearance.

[0129] 7. Preparation Method: Coating formulations can be synthesized starting from a standard premix of protective colloids, surfactants, and oxidants. Monomers may be added subsequently, followed by additional surfactants and reducing agents.

[0130] Protective colloids may contain hydroxyethyl cellulose, polyvinyl alcohol, casein, hydroxyethyl starch, and carboxymethyl cellulose.

[0131] The amount of protective colloid added may be about 0.05% or more, about 0.1% or more, about 0.5% or more, about 1.0% or more, about 1.5% or more, about 2% or more, or about 2.5% or less, about 3.0% or less, about 3.5% or less, about 4.0% or less, about 4.5% or less, or within any range using these endpoints.

[0132] The free radical initiating catalyst used to achieve polymerization is generally called a redox catalyst. As is known, redox catalysts include an oxidizing agent and a reducing agent. The oxidizing and reducing components can be any of those commonly used in vinyl acetate emulsion polymerization, such as hydrogen peroxide, potassium persulfate, tert-butyl peroxypentanoate, etc., and preferred reducing agents are ferrous ammonium sulfate and sodium formaldehyde sulfoxylate or zinc formaldehyde sulfoxylate.

[0133] The premix can be formed by adding a standard amount of water, a protective colloid such as hydroxyethyl cellulose, and a free radical initiating oxidant to a first container. Then, approximately 0-70% of the total surfactant used can be added to the first container and mixed therein. The remaining surfactant is mixed with the monomers in a second container or added separately. In either case, they can be added after a delay. To initiate polymerization, the monomers and reducing agent can be added to the first container over a period of time and at a certain rate, such that the unreacted vinyl acetate in the first container remains at approximately 3-5% by weight of the emulsion or latex. After all the monomers have been added to the first container, the residual vinyl acetate is then reduced to less than 0.5% by adding additional oxidant and reducing agent. At the end of polymerization, the pH can be adjusted to approximately 5.5 by adding a base such as ammonium hydroxide.

[0134] Regarding the polymerization process, protective colloids, particularly cellulose ethers, are used to maintain emulsion stability. Higher levels of colloids tend to improve stability and also increase particle size. Surfactants also provide emulsion stability. However, unlike colloids, surfactants tend to reduce particle size when present in the initial polymerization and show better particle size reduction effects when added later. Particle size optimization can be achieved by working protective colloids and surfactants together.

[0135] Stirring is another variable that can affect the particle size in polymer emulsions. Stirring should be gentle to ensure proper heat transfer and maintain product stability. Vigorous stirring should be avoided. Regarding particle size control, if larger particles are desired, the stirring rate can be reduced; and if smaller particles are desired, the intensity of stirring can be increased. If stirring cannot be changed, adjustments can be made to the surfactant or protective colloid.

[0206] These compounds can be synthesized using a variety of methods. One such method involves reacting an amino acid (e.g., an N-alkylated or N-acylated amino acid) with a siloxane to convert the C-terminus of the amino acid into the desired siloxane derivative. For example, the N-terminus of the amino acid can be further alkylated to generate a quaternary ammonium.

[0207] Amino acids can be naturally occurring or synthetic, or derived from ring-opening reactions of lactams (such as caprolactam). Ring-opening reactions can be acid- or base-catalyzed, and examples of acid-catalyzed reactions are shown in Scheme 1 below.

[0208] Option 1 Amino acids may have as few as one or as many as 12 carbons between the N-terminus and C-terminus, for example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 carbons. The alkyl chain may be branched or straight. The alkyl chain may be inserted with nitrogen, oxygen, or sulfur. The alkyl chain may be further substituted with one or more substituents selected from hydroxyl, amino, amide, sulfonyl, sulfonate, carboxyl, and carboxylic acid esters. The N-terminal nitrogen may be acylated or alkylated with one or more alkyl groups. For example, an amino acid may be 6-(dimethylamino)hexanoic acid.

[0209] Siloxanes can be substituted with one or more alkoxy groups, such as methoxy, ethoxy, isopropoxy, tert-butoxy, etc. Siloxanes can be further substituted with one or more alkyl groups (e.g., propyl), wherein the alkyl groups can be further substituted with suitable functional groups to allow the siloxane to couple with amino acids, such as nitrogen. For example, a siloxane can be 3-aminopropyltris(trimethylsiloxy)silane.

[0210] The siloxane derivatives of amino acids can be synthesized according to Scheme 2 below. As shown, 6-aminohexanoic acid can be alkylated at the N-terminus by reflux in formic acid with formaldehyde to obtain 6-(dimethylamino)hexanoic acid. Then, the free carboxylic acid is coupled with 3-aminopropyl(trimethylsiloxy)silane in refluxed toluene to obtain the desired siloxane derivative.

[0211] Option 2 The N-terminal nitrogen can be further derivatized to alter or improve water solubility and surface activity. Scheme 3 below shows the sample synthesis scheme in which the N-terminal nitrogen is alkylated to provide quaternary ammonium.

[0212] Option 3 Suitable alkylating agents may include, for example, benzyl bromide, ethyl bromoacetate, allyl iodide, propargyl bromide, 1-bromo-2-(2-methoxyethoxy)ethane, bromophosphonates, 3-iodopropanol, 3-bromopropanol, 2-iodoethanol, 2-bromoethanol, 6-bromohexanoic acid, 4-(4-bromobutyl)benzoic acid, and 4-(bromomethyl)benzoic acid. The two molecules of Formula I can be linked by treating the N-terminal nitrogen with a bifunctional alkylating agent (e.g., 1,3-dibromopropane).

[0213] The compounds disclosed herein exhibit surface-active properties. These properties can be measured and described by various methods. One way to describe surfactants is through the critical micelle concentration (CMC) of the molecule. The CMC can be defined as the concentration of surfactant at which micelles form, and above this concentration, all additional surfactants are incorporated into the micelles.

[0214] As the surfactant concentration increases, the surface tension decreases. Once the surface is completely covered by surfactant molecules, micelles begin to form. This point represents the CMC (Content Mold Value) and the minimum surface tension. Further addition of surfactant will not further affect the surface tension. Therefore, the CMC can be determined by observing the change in surface tension with surfactant concentration. One such method for measuring this value is the Wilhelmy plate method. The Wilhelmy plate is typically a thin iridium-platinum plate, which is attached to a balance by a wire and placed perpendicular to the air-liquid interface. The balance is used to measure the force applied to the plate by wetting. The surface tension (γ) is then calculated using this value according to Equation 1: Equation 1: γ = F / l cos θ where l is equal to the perimeter of wetting (2w + 2d, where w and d are the thickness and width of the plate, respectively), and cosθ, the contact angle between the liquid and the plate, is assumed to be 0 in the absence of existing literature values.

[0215] Another parameter used to evaluate surfactant performance is dynamic surface tension. Dynamic surface tension is the surface tension value over the lifetime (age) of a specific surface or interface. In the case of liquids with added surfactants, this can differ from the equilibrium value. Immediately after surface formation, the surface tension is equal to that of the pure liquid. As mentioned above, surfactants reduce surface tension; therefore, the surface tension decreases until an equilibrium value is reached. The time required to reach equilibrium depends on the diffusion and adsorption rates of the surfactant.

[0216] One method for measuring dynamic surface tension relies on a bubble pressure tensiometer. This device measures the maximum internal pressure of a bubble forming in a liquid via a capillary. The measured value corresponds to the surface tension at a specific surface lifetime (i.e., the time from the start of bubble formation to the occurrence of the maximum pressure). The dependence of surface tension on surface lifetime can be measured by varying the rate at which bubbles are formed.

[0217] Surfactant compounds can also be evaluated by their wetting ability on a solid matrix, which is measured by the contact angle. When a droplet comes into contact with a solid surface in a third medium such as air, a triple line is formed between the liquid, gas, and solid. The angle between the unit vector of surface tension acting on the triple line and tangent to the droplet and the surface is described as the contact angle. The contact angle (also called the wetting angle) is a measure of how well a solid is wetted by a liquid. In the case of complete wetting, the liquid spreads completely over the solid, and the contact angle is 0°. The wetting properties of a given compound are typically measured at concentrations of 1–10 × CMC; however, this is not a concentration-dependent property. Therefore, wetting properties can be measured at higher or lower concentrations.

[0218] In one method, an optical contact angle goniometer can be used to measure the contact angle. This device uses a digital camera and software to extract the contact angle by analyzing the profile shape of a droplet attached to a surface.

[0219] Potential applications of the surfactant compounds disclosed herein include formulations for use in shampoos, conditioners, detergents, spot-free rinsing solutions, floor and carpet cleaners, graffiti removers, wetting agents for crop protection, adjuvants for crop protection, and wetting agents for aerosol spraying.

[0220] Those skilled in the art will understand that small differences between compounds can lead to significantly different surfactant properties, allowing different compounds to be used with different substrates in different applications. They will also understand that the properties of surfactants may not be predictable from their chemical structure, as further demonstrated below. For example, surfactant 9 and the comparative surfactant differ only in the number of methylene groups in R3, yet they exhibit different surfactant properties. Surprisingly, surfactant 9 exhibits superior activity, as further described below, while the comparative surfactant exhibits inferior surfactant properties.

[0227] The minimum surface tension plateau value of the surfactants that can be used in the formulations disclosed herein may be less than about 25 mN / m, less than about 24 mN / m, less than about 23 mN / m, less than about 22 mN / m, less than about 21 mN / m, less than about 20 mN / m, less than about 19 mN / m, less than about 18 mN / m, less than about 17 mN / m, less than about 16 mN / m, or less than about 15 mN / m, or may have any minimum surface tension plateau value falling within the range encompassed by the above endpoints.

[0228] Surfactants with antimicrobial activity: Cells are the basic unit of all living organisms, each with its own set of organelles responsible for performing various cellular functions and storing genetic information for the organism's development and function. The cell's outer boundary, called the cell membrane, acts as a barrier and regulates the transport of substances between the inside and outside of the cell. The cell membrane can be disrupted through a process called lysis, leading to cell death, which is the fundamental basis of all antimicrobial processes. The use of surfactants with inherent bactericidal activity can be very important in coatings, adhesives, inks, and various other applications, especially when this function cannot be introduced in other ways, and for economic reasons.

[0229] Traditionally, cationic surfactants have been used as antimicrobial agents in industries such as the food industry and hospitals. Unlike traditional antimicrobial chemicals that rely on a "lock-and-key" mechanism, cationic surfactants are known to exert their antimicrobial activity by disrupting bacterial membranes through electrostatic and hydrophobic interactions. (Zhou & Wang, Structure-activity relationship of cationic surfactants as antimicrobial agents, Current Opinion in Colloids & Interface Science, 45:28-43 (2020)). As good antimicrobial agents, surfactants need to be able to kill bacteria or other unwanted pathogenic microorganisms effectively without interfering with mammalian cells. Currently, with increasing awareness of the potential cytotoxicity and environmental hazards of certain chemicals, collaborative efforts are underway to develop surfactants that reduce cytotoxicity issues, which may arise from the lack of selectivity of conventional quaternary ammonium surfactants, which are known to indiscriminately disrupt biofilms regardless of cell type.

[0230] The surfactants of this disclosure have been evaluated for antimicrobial activity using a standard protocol known as the minimum inhibitory concentration (MIC) test. The table below shows the MIC results for examples of surfactants in this disclosure.

Antimicrobial MIC Studies: Known methods and standard protocols were used, along with various types of microorganisms as treatment targets, to test the antimicrobial properties of surfactants. More specifically, a serial dilution method was employed, using a minimum inhibitory concentration (MIC) test protocol, to measure concentration-dependent microbial growth inhibition against Gram-positive bacteria (e.g., anaerobic Streptococcus mutans and Staphylococcus aureus, which is typically aerobic but can also grow under anaerobic conditions) and Gram-negative bacteria (e.g., anaerobic Escherichia coli or aerobic Pseudomonas aeruginosa).

[0264] The bacteria were multiplied overnight in a suitable culture medium (tryptone soy broth). Prior to testing, the concentration of the test organisms was determined using a spectrophotometer capable of measuring optical density. The bacterial samples were then diluted to approximately 1E3 to 1E4 CFU / mL. Subsequently, 10 mL of the prepared bacterial culture was inoculated into the wells of a 96-well plate, each well containing a suitable culture medium, namely tryptone soy agar. Once inoculated, these wells were treated with serially diluted test samples and incubated at 37±1°C and a relative humidity of at least 90% for approximately 24±1 hours.

[0265] The test surfactant was prepared into a series of dilutions. All dilutions were sequentially applied to 96-well microplates using a multichannel pipette. The dilution series was established previously through a range-finding exercise to determine the upper limit of the high concentration and the lower concentrations of the series of dilutions to ensure that the test substance did not completely inhibit bacterial growth but still showed an effect.

[0266] Then, the MIC is used to determine the approximate concentration of the test surfactant that inhibits bacterial growth.

[0267] In this antimicrobial test protocol, a reference substance is usually used as a positive control. In this example, quaternary ammonium ADBAC with CAS number 139-08-2 is used as a suitable test reference.

[0268] Test measurements were performed on repeated 96-well plates, and the rounded integer mean of the determined MIC was reported. The repeated data were averaged using the formula: Arithmetic Mean = Sum of numbers in the set of interest / Number of items, to determine the mean (arithmetic mean) for the selected measurements. Measurement variability was then reported in the form of MIC + / - based on the determined mean.
