Description
Attorney Docket No.: ARXP-329-PCT (LP3750PC00)POLYETHERAMINE-BASED COMPOSITIONSRELATED APPLICATIONS
[0001] The present application is based on and claims priority to U.S. Provisional Patent application Serial No. 63 / 749817, filed on January 27, 2025, which is incorporated herein by reference.BACKGROUND
[0002] Isothiazolinones and pyrithiones have been widely used as broad-spectrum biocides for the preservation of water-based products such as latex, paints and adhesives against spoilage from bacteria, yeasts and fungi. Typical examples of isothiazolinone biocides include 5-chloro-2-methyl-4-isothiazolinone (CMIT), 2-methyl-4-isothiazolinone (MIT), l,2-benzisothiazolin-3-one (BIT), n-butyl-l,2-benzisothiazolin-3-one (BBIT), 2-octyl-4-isothiazolinone (OIT), and 4,5-dichloro -2-octyl-4-isothiazolinone (DCOIT). Typical examples of pyrithiones include zinc pyrithione (ZPT), sodium pyrithione (NaPT) and copper pyrithione (CuPT). However, both isothiazolinones and pyrithiones are under regulatory scrutiny.
[0003] As such, evolving regulations require reduced levels of allowable active biocides in products. Certain countries, such as Canada, forbid the use of certain biocides in certain applications (e.g., ZPT is forbidden in textiles). As a result, the industry is now facing not only the ineffective biocidal performance at lower active level, but also the fewer choices of effective biocides.
[0004] For these reasons, there exists a strong need to develop new formulations of ingredients that enable preservation in the current regulatory landscape. Of particular interest are ingredients that enhance the activity of primary actives or can provide preservation with minimal or no use of certain unfavorable preservatives. Additional interest is driven by those ingredients that can allow for preservation meeting “label free” requirements in certain regions. Further, if the ingredient is multifunctional, there may be simultaneous savings and SKU-reduction on functions supplied by numerous other additives (e.g., dispersants, defoamers, rheology modifiers, surfactants, pH adjusters).SUMMARY
[0005] The present disclosure is generally directed to a method for preserving a polymer emulsion in the wet state. The method may include dosing the polymer emulsionAttorney Docket No.: ARXP-329-PCT (LP3750PC00)with a poly etheramine. For instance, the poly etheramine may be present in the polymer emulsion at a concentration of from about 1000 ppm to about 10000 ppm.
[0006] Additionally, example aspects of the present disclosure are directed to a method for preparing a water-based industrial material. The method may include dosing the waterbased industrial material with a polymer emulsion disclosed herein.
[0007] Other features and aspects of the present disclosure are discussed in greater detail below.BRIEF DESCRIPTION OF THE DRAWINGS
[0008] A full and enabling disclosure of the present disclosure is set forth more particularly in the remainder of the specification, including reference to the accompanying figure, in which:
[0009] Figure 1 depicts chemical structures of polyetheramines (PEA).
[0010] Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present invention.DETAILED DESCRIPTION

The number of moles of alkylene oxide reacted per mole of the mono-alcohol may be varied as may be desired, but typically is from about 2 to about 50 on average. If more than one type of alkylene oxide is used, the alkylene oxides may be reacted as a mixture (to provide a polyoxyalkyleneAttorney Docket No.: ARXP-329-PCT (LP3750PC00)segment having a random copolymer structure) or sequentially (to provide a polyoxyalkylene segment having a block copolymer structure).
[0038] Another type of nonionic surfactant for use in the present disclosure is an alkoxylated aliphatic mono-alcohol which is an ethoxylated Cio-Cis aliphatic alcohol (in particular, a linear primary C12-C16 aliphatic alcohol or mixture of such alcohols) which has been reacted with about 6 to about 15 moles of ethylene oxide per mole of aliphatic alcohol to provide an alkoxylated alcohol containing an average of about 6 to about 15 oxy ethylene repeating units per molecule). For example, the alkoxylated aliphatic mono-alcohol may be an ethoxylated C12-C16 linear aliphatic alcohol containing an average of about 8 to about 12 ethylene oxide units per molecule. In particular, ethoxylated tridecanol containing an average of about 10 ethylene oxide units is suitable for use in the present disclosure.
[0039] Another type of nonionic surfactant for use in the present disclosure is an alkoxylated C2-C8 aliphatic alcohol containing both ethylene oxide and propylene oxide units. The C2-C8 aliphatic alcohol may be n-butanol, for example. The ethylene oxide and propylene units may be arranged in a block manner (e.g., the surfactant may contain a polyoxyethylene block and a polyoxypropylene block). Also suitable for use as nonionic surfactants are alkoxylated phenols, in particular ethoxylated phenols wherein the phenol may be substituted with one or more alkyl groups (in particular, long chain alkyl groups such as nonyl or dodecyl groups or aralkyl groups, such as in tristyrylphenol).
[0040] Suitable anionic surfactants include, but are not limited to, surfactants containing anionic functional groups at their head, such as sulfate groups, sulfonate groups, phosphate groups, and carboxylate groups. The cationic counterion to the anionic functional group may be, for example, an alkali metal (e.g., Na, K) or an amine (ammonium) cation such as a quaternary ammonium. Useful types of anionic surfactants in the present disclosure include, but are not limited to, alkyl sulfates, alkyl ether sulfates, sulfated alkanolamides, glyceride sulfates, alkyl aryl sulfonates (including straight-chain alkylbenzenesulfonates, branched alkylbenzenesulfonates, alkylnaphthalene-sulfonates), alpha olefin sulfonates, lignosulfonates, sulfo-carboxylic compounds (e.g., sodium lauryl sulfoacetate, sulfosuccinates (including dialkylsulfosuccinates), sulfosuccinamates, organo phosphored surfactants, sacrosides, hydroxyalkane-sulfonates, alkanesulfonates, alkylphenoxy polyoxyethylene propyl sulfonates, salts of polyoxyethylenealkyl sulfophenyl ethers, sodium N-methyl-N-oleyltaurates, monoamide di sodium N-alkyl sulfosuccinates, petroleum sulfonates, sulfated castor oil, sulfated tallow oil, salts of sulfuric esters of aliphatic alkylesters, salts of alkylsulfuric esters, salts of alkylsulfuricAttorney Docket No.: ARXP-329-PCT (LP3750PC00)esters, sulfuric esters of polyoxyethylenealkylethers, salts of sulfuric esters of aliphatic monoglycerides, sodium salt of the monosulfated monoglyceride of hydrogenated coconut oil fatty acids, salts of sulfuric esters of polyoxyethylene alkylphenylethers, salts of alkylphosphoric esters, salts of phosphoric esters of polyoxyethylenealkylethers, salts of phosphoric esters of polyoxyethylenealkylphenylethers, partially saponified compounds of styrene-maleic anhydride copolymers, partially saponified compounds of olefin-maleic anhydride copolymers, naphthalenesulfonate-formalin condensates, higher alkyl sulfoacetates, and higher fatty acid esters of 1,2-dihydroxy propane sulfonate and combinations thereof. Particular among these anionic surfactants are sulfonate surfactants, in particular salts of alkyl aryl sulfonates, especially salts of Cs-Cis alkyl benzene sulfonates such as salts of dodecylbenzene sulfonate, and combinations thereof.
[0041] A total amount of surfactant is used that is effective, in combination with the any thickeners and / or suspending agent that may be present in the composition, to provide a physically stable dispersion. The amount of surfactant needed to achieve a physically stable dispersion will depend on a number of factors, including, for instance, the types and amounts of the poly etheramine and thickeners / suspending agents present in the polymer emulsion and the types of surfactants utilized. Typically, however, an amount of surfactant is used which is sufficient to provide a weight ratio of polyetheramine to surfactant within the range of from about 5 : 1 to about 50:1 or from about 6: 1 to about 20: 1.
[0042] Further, certain surfactants and combinations of surfactants also have well-known activities disrupting membranes. This activity is general to several cationic surfactants, but is also true of certain non-ionic and ionic surfactants.
[0043] If desired, the polymer emulsions of the present disclosure may include one or more substances capable of functioning as thickener or suspending agents to render the compositions physically stable. In particular, the types and amounts of thickeners and / or suspending agents may be selected such that at twenty-five degrees Celsius (25 °C) the resulting polymer emulsion has a viscosity of at least 300 cps. In other example embodiments, the viscosity of the polymer emulsion at 25 °C is at least 400 cps or at least 500 cps. Generally, it will be desirable for the viscosity of the polymer emulsion to not be increased to the point where it becomes difficult to transfer or handle the polymer emulsion by pumping. Viscosity is measured using a Brookfield viscometer (spindle #5, 100 rpm).
[0044] Suitable thickeners / suspending agents include, without limitation, clays (including natural clays and organo-modified clays), silicates (e.g., silicas such as modifiedAttorney Docket No.: ARXP-329-PCT (LP3750PC00)silicas and fumed silicas), polysaccharides (e.g., gums such as xanthan gum, cellulosic polymers), polyacrylates, and the like and combinations thereof.
[0045] One or more other components, in addition to those mentioned above, may additionally be present in the polymer emulsions of the present disclosure. In certain example embodiments, however, the polymer emulsion consists essentially of or consists of only the aforementioned components, except that one or more defoamers may optionally be present in such example embodiments.
[0046] Additional optional components include, but are not limited to, dispersants, defoamers (antifoams, e.g., silicone-based defoamers, mineral oil-based defoamers, hydrophobic silica-based defoamers), sequestering / chelating agents, fillers, coloring agents, antifreezing agents, corrosion inhibitors (anti-corrosion additives), ultraviolet light stabilizers, antioxidants, solvents, co-solvents, scale inhibitors, and the like.
[0047] Further components may include ingredients known in the art of preparing stable isothiazolinone concentrates, most typically magnesium nitrate, sodium nitrate, potassium iodate, copper nitrate, or other salts known in the art as particularly useful as stabilizing agents. Concentrates of isothiazolinones and polyetheramines may utilize one or more of these established stabilization systems to overcome reactivity between the polyetheramine and isothiazolinone.
[0048] The polymer emulsions disclosed herein may also be pH adjusted to affect the chemical stability or solubility of the isothiazolinone or polyetheramine in the formulation. Methods well known in the art may be used for controlling the chemical stability of isothiazolinone concentrates.
[0049] The polymer emulsions disclosed herein may also contain other ingredients known to stabilize isothiazolinones.
[0050] Polymer emulsions in accordance with the present disclosure may be prepared by adaptation of any of the techniques known in the art for creating dispersions of waterinsoluble substances in water using surfactants (emulsifiers), thickeners, suspending agents, and combinations of these ingredients. For example, a suitably sized mixing vessel may be charged with water, followed by the surfactants desired to be included in the polymer emulsion. While agitating the surfactant / water mixture, the polyetheramine and a portion of the thickeners / suspending agents are added. Mixing at high speed and / or high shear may be continued until a homogeneous emulsion having the desired particle size (typically 5 to 75 microns) is obtained. The mixture may be heated to a temperature somewhat above room temperature during this step. The remaining thickeners / suspendingAttorney Docket No.: ARXP-329-PCT (LP3750PC00)agents may then be added, and the mixture agitated until homogeneous once again. The mixture may be cooled to room temperature prior to the final addition of thickeners / suspending agents. The polymer emulsion may then be transferred by pumping or other means to one or more suitable storage containers such as tanks, drums or totes.

[0081] The susceptibility of latex emulsion #1 (self-crosslinking acrylic emulsion, 44% Solid) prepared with various poly etheramines (PEA), alone or in combination with 1,2-benzisothiazolin-3-one (BIT) were evaluated. Paints (58% PVC, 30% Solid Vol, 46 g / L VOC, Table 1) prepared from these PEA or PEA / IST containing polymer emulsions were also evaluated in parallel. Product susceptibility was assayed using a modified ASTM D2574 Standard Test Method of Resistance of Emulsion Paints in the Container to Attack by Microorganisms. BIT (Proxel BD20) and polyetheramines were added into the latex emulsion to achieve 360 ppm BIT and 0.8% polyetheramine. The dosed latex emulsions were speed mixed at 2000 rpm for 2 minutes for homogenous emulsions. Aliquots of the dosed latex emulsions were used for formulating the latex paints to achieve the dose level of 72 ppm BIT and 0.16% poly etheramine. Both the dosed latex emulsions and paints were equilibrated for at least overnight prior to any tests.Table 1. Composition of Latex Paint #1Attorney Docket No.: ARXP-329-PCT (LP3750PC00)
[0082] The wet-state preservation test is designed to determine the susceptibility of products to microbial growth in a liquid sample when inoculated with spoilage microbes. The following bacterial strains were utilized for the inoculations:■ Acinetobacter calcoaceticus ATCC 14987■ Enterobacter cloacae ATCC 7256■ Escherichia coli ATCC 11229■ Pseudomonas aeruginosa ATCC 10145
[0083] Bacterial cultures were obtained from a culture collection stored at -80 °C. Test bacteria were adapted to grow at pH levels of 5, 7, and 9. Test organisms were chosen from the pH that most closely matched that of the sample. Lawns of the test bacteria were harvested from tryptic soy agar (TSA) using sterile PBS. Where growth was observed in the unpreserved control after the first inoculation, a standard inoculation regimen was followed. For each of the sample ladder(s) the inoculum volume was equivalent to 10% of the paint size. The efficacy of the preservatives in controlling contamination was monitored at 7 days after each inoculation by streaking the samples on plates of Campylobacter Blood Agar (CVA) for bacterial challenge samples. CVA plates were evaluated after incubation at 33 °C for 48 hours. The degree of growth on CVA streak plates was interpreted in Table 2.Table 2. Rating Scale of Microbial Growth
[0084] The susceptibility of the latex emulsion with and without BIT / polyetheramine-dosed latex emulsions is shown in Table 3. Both BIT alone and BIT / poly etheramine combinations passed the wet-state preservation test at 360 ppm and 360 ppm / 0.80% levels while most polyetheramine alone failed at 0.80% level except for PEA D230 and RFD270 with > 6xl0'2meq / g amine level.Table 3. Summary Table of Wet-State Preservation Efficacies of BIT / PEA in Latex Emulsion #1Attorney Docket No.: ARXP-329-PCT (LP3750PC00)
[0085] The wet-state preservation efficacies of BIT / polyetheramine-dosed latex paints are given in Table 4. Only BIT / polyetheramine combinations with > l><10'2meq / g amine level passed the test at 72 ppm / 0.16% level while BIT alone, poly etheramine alone and the rest of BIT / polyetheramine combinations failed at the respective 72 ppm, 0.16% and 72 ppm / 0.16% level.Table 4. Summary Table of Wet-State Preservation Efficacies of BIT / PEA in Latex Paint #1
[0086] Overall, the above wet-state preservation results demonstrate that the paint prepared from the polymer emulsions containing both BIT and polyetheramine combinations are less susceptible to growth.Example 2pH o f BIT / PEA in Latex Emulsion and PaintAttorney Docket No.: ARXP-329-PCT (LP3750PC00)
[0087] In addition to wet-state preservation efficacies, the pHs of BIT / PEA-dosed latex emulsions and paints in Example 1 were also measured using a pH meter. Polyetheramine leads to higher alkaline either by itself or in combination with BIT (Table 5). This is particularly beneficial to latex emulsion and paint as alkaline pH is needed for storage stability provided by anionic additive package.Table 5. pHs of BIT / PEA-dosed Latex Emulsions and Paints

In addition, it should be understood that aspects of the various embodiments may be interchanged both in whole or in part. Furthermore, those of ordinary skill in the art will appreciate that the foregoing description is by way of example only, and is not intended to limit the invention so further described in such appended claims.
