Description

Technical Field

[0001] The present invention relates to a water-in-oil (W / O) type emulsion composition comprising water, at least one hydrocarbon solvent, at least one nonionic emulsifier, and at least one stabilizer, wherein the stabilizer provides freeze-thaw stability to the W / O type emulsion. When the W / O type emulsion composition is subjected to freeze-thaw cycles, the freeze-thaw stabilizer prevents the destruction of the emulsion or enables the reformation of the emulsion by simply shaking the container containing the emulsion composition. The stable W / O type emulsion composition of the present invention is particularly suitable for use as a cleaning and / or polishing composition, and more particularly, is useful for compositions for cleaning and / or polishing furniture, shoes, and automobiles.

Background Art

[0002] When a typical water-in-oil (W / O) type emulsion composition passes through freeze-thaw cycles, the emulsion usually breaks, i.e., the aqueous phase is no longer uniformly dispersed throughout the composition, and a large amount of water remains at the bottom of the container holding the composition. Freeze-thaw cycles typically occur during winter shipping or warehouse storage of products containing the emulsion composition. This is undesirable for consumer products because the composition is not delivered in a form that provides the performance expected by the consumer, regardless of whether the composition is delivered in an aerosol form such as a pump spray, trigger spray, pour bottle, or squeeze bottle or a non-aerosol form.

[0003] A freeze-thaw stable W / O type emulsion preferably can maintain the same emulsion structure when the emulsion is subjected to freeze-thaw cycles or can be reformed by simply shaking the container holding the emulsion composition after the destruction of the emulsion. Thereby, the user can experience the desired performance expected of the composition.

[0004] One effort to provide a freeze-thaw stable W / O emulsion is disclosed in Patent Document 1 regarding lubricant products for cooking appliances. A freeze-thaw stable W / O lecithin emulsion is described that involves adding a polyol to a W / O lecithin emulsifying system that controls both components and concentration to maintain a critical acid value level in order to suppress or prevent a "destructive" conversion to a water-in-oil heterogeneous component with a high water content despite repeated cycles in the freeze-thaw state. A stable W / O lecithin emulsion was obtained, but due to the strict requirement of the "critical acid value level" as described, the application of the described method to other emulsifying systems is severely limited.

[0005] Another approach is disclosed in Patent Document 2 regarding cosmetic products. A freeze-thaw stable silicone water-in-oil emulsion is described. Glycerin was used as a freeze-thaw stabilizer to prevent the destruction of the emulsion after freeze-thaw cycles. Other polyols, lower alcohols, organic acid salts or inorganic salts were combined with glycerin to improve freeze-thaw stability. A freeze-thaw stable emulsion was obtained in this way, but the unique silicone water-in-oil emulsion is costly and thus difficult to use in other product categories.

[0006] In the food industry, many processed foods with W / O emulsifying systems (e.g., whipped toppings, table spreads, sauces) are frozen to improve long-term storage and then thawed for further processing or consumption. The paper in Non-Patent Document 1 evaluated the factors affecting the stability of W / O emulsions during freeze-thaw cycles, namely, interfacial crystallization and network crystallization, and the order of crystallization events (i.e., dispersed phase and continuous phase, or vice versa). Destabilization was reported to be most evident in the liquid emulsifier and the continuous oil phase that solidifies before the dispersed phase. Emulsions stable to freeze-thaw cycles were obtained when the emulsifier crystallized at the oil-water interface or when the continuous phase was crystallized after dispersing the aqueous phase. This method may be good guidance for foods, but it is not very effective in other product categories.

[0007] In furniture care products, shoe care products, and car care products, wax and methanol function as stabilizers for producing a freeze-thaw stable W / O emulsion. However, these freeze-thaw stabilizers usually cannot prevent the destruction of the emulsion, but can enable the reformation of the emulsion by simply shaking the container holding such an emulsion. The disadvantages of using wax as a freeze-thaw stabilizer include the accumulation of wax remaining on the treated surface and the need for the user to make more effort to completely wipe off the composition during application and use. Including methanol in the composition not only causes government regulation problems in countries such as Russia, but also potential safety problems during the manufacture of the product.

[0008] Therefore, an emulsified composition that prevents the destruction of the emulsion or enables the reformation of the emulsion by simply shaking the emulsified composition after the destruction of the emulsion is particularly advantageous in furniture care products, shoe care products, and car care products while avoiding regulatory problems and potential safety problems in particular, and is also easy to wipe off. The present invention provides a new W / O emulsified composition that is stable against freeze-thaw cycles and can address the problems of the prior art. Furthermore, the present invention provides a new W / O emulsified composition that can be reformed by simply shaking the composition after the emulsion has broken through the freeze-thaw cycle.

Summary of the Invention

Means for Solving the Problems

[0011] The present invention relates to a water-in-oil (W / O) type emulsified composition comprising water, at least one hydrocarbon solvent, at least one nonionic emulsifier, and at least one freeze-thaw stabilizer, wherein when the W / O type emulsified composition is subjected to a freeze-thaw cycle, destruction of the emulsion is prevented or an emulsion that has once broken can be re-formed by simply shaking the container containing the emulsified composition. As described below, other components may be included in the emulsified composition.

[0012] The W / O type emulsified composition is prepared by dispersing an aqueous phase in an oil phase. The oil phase contains at least one hydrocarbon solvent and at least one nonionic emulsifier. Suitable freeze-thaw stabilizers for inclusion in the composition are (1) polyols such as glycerin, sorbitol, and maltitol, (2) sugars such as glucose and sucrose, (3) polar aprotic solvents such as dimethyl sulfoxide (DMSO), and (4) amphoteric compounds such as lauryldimethylamine oxide. Depending on the type of freeze-thaw stabilizer used and the composition of the W / O type emulsion, a lower or higher concentration of the freeze-thaw stabilizer is used. Generally, a higher concentration of the freeze-thaw stabilizer is used to prevent destruction of the emulsion, while a lower concentration of the stabilizer can be understood to enable re-formation of the emulsion by simply shaking the container holding the emulsified composition. In the commercial world, such lower concentrations are usually preferred by companies for lower costs. If the concentration of the freeze-thaw stabilizer is too low, the emulsified composition loses its freeze-thaw stability and cannot re-form the emulsion even with simple shaking.

[0013] The W / O type emulsion composition of the present invention is particularly useful in furniture care products, shoe care products, and car care products. Typical furniture care products, shoe care products, and car care products containing a W / O type emulsion as part of them include water, at least one hydrocarbon solvent, at least one nonionic emulsifier, at least one freeze-thaw stabilizer, and optionally a film-forming agent (e.g., silicone oil), a fragrance component, a preservative, or one or more of conventional auxiliaries for inclusion in furniture care, shoe care, and car care cleaning and / or polishing compositions.

Brief Description of the Drawings

Mode for Carrying Out the Invention

[0015] A water-in-oil (W / O) type emulsified composition with freeze-thaw stability is described. These stable emulsions are provided using one of a functional ingredient called a "freeze-thaw stabilizer". These freeze-thaw stabilizers prevent the destruction of the emulsion after being subjected to freeze-thaw cycles, or after the destruction of the emulsion, enable the reformation of the emulsion by simply shaking (i.e., manually or by hand) the container holding the broken emulsion. Figure 1 shows a W / O type emulsified composition containing a hydrocarbon solvent, a nonionic emulsifier, and water but not containing a freeze-thaw stabilizer, where the aqueous phase is uniformly dispersed in the oil phase, i.e., the emulsion is not broken. Figure 2 shows that after being subjected to a freeze-thaw cycle, the emulsion is broken, i.e., a part of the aqueous phase is separated from the emulsified composition and is currently present at the bottom of the container. When at least one of the freeze-thaw stabilizers of the present invention is contained in the W / O type emulsified composition, depending on the concentration of the freeze-thaw stabilizer, the emulsion is either retained as shown in Figure 1 without being broken even after being subjected to a freeze-thaw cycle, or even if it is broken as shown in Figure 2, it can be reformed as the emulsion shown in Figure 1 by simply shaking the container holding the emulsified composition. In either case, the consumer can continuously experience the expected performance of the emulsified composition during use.

[0016] During use, emulsified compositions for which the freeze-thaw stabilizers of the present invention are particularly beneficial are furniture care products, shoe care products, and car care products such as compositions for cleaning and / or polishing furniture, shoes, and automobiles. Furniture care products, shoe care products, and car care products based on W / O type emulsions generally contain water, a hydrocarbon solvent, a nonionic emulsifier, optionally a film-forming agent, a fragrance component, a preservative, and one or more of the other additives conventionally included in products for cleaning and / or polishing furniture, shoes, and automobiles.

[0017] The cryoprotectants of the present invention for inclusion in a W / O type emulsion composition include (a) polyols (i.e., compounds having at least two hydroxyl groups), such as glycerin, ethylene glycol, sorbitol, and maltitol, (b) sugars, such as glucose and sucrose, (c) polar aprotic solvents, such as dimethyl sulfoxide (DMSO), and (d) amphoteric compounds, such as lauryldimethylamine oxide. Generally, when a high concentration of cryoprotectant is included in an emulsion composition, it is possible to prevent the W / O type emulsion from breaking, while when the concentration of the stabilizer is low, simply shaking the container holding the emulsion composition enables reformation of the broken emulsion. If the concentration of the cryoprotectant is too low, the emulsion is not stable to freeze-thaw, i.e., after the emulsion breaks in a freeze-thaw cycle, it cannot be reformed even by simple shaking. Therefore, there is a minimum concentration required to enable freeze-thaw stability. The minimum concentration of the cryoprotectant may vary depending on the emulsion system. The preferred concentration range for use is from about 0.01 to about 10 wt% of the cryoprotectant, more preferably from about 0.1 to about 2 wt%, and most preferably from about 0.1 to about 1 wt%. The cryoprotectants may be used alone or in combination.

[0018] The weight percentages (wt%) of the total W / O type emulsion composition used in this specification and the claims are based on 100 wt%. The wt% of a given material is based on the wt% of the active ingredient of the material, unless otherwise specified.

[0019] Regarding hydrocarbon solvents suitable for use in W / O type emulsion compositions, emulsion compositions particularly useful as products for cleaning and / or polishing furniture, shoes, and automobiles are those conventionally known to be used in furniture care compositions, shoe care compositions, and car care compositions for removing solvent-soluble residues from substrate surfaces. Examples of hydrocarbon solvents useful alone or in combination include, but are not limited to, saturated hydrocarbon solvents (such as alkanes) and unsaturated hydrocarbon solvents (such as alkenes, alkynes, and aromatics).

[0020] Commercially available saturated hydrocarbon solvents such as those sold under the trade name "ISOPAR" or "EXXSOL" from ExxonMobil, or isoparaffinic hydrocarbon solvents sold under the trade name "SOLTROL" from Chevron Phillips, are currently preferred because they have little odor. Preferred solvents have a shorter carbon length (i.e., C 10 or less).

[0021] Other suitable saturated hydrocarbon solvents include pentane, hexane, heptane, naphtha, petroleum spirit, and mineral oil. Examples of unsaturated hydrocarbon solvents useful alone or in combination include, but are not limited to, turpentine, toluene, and xylene.

[0022] The various saturated hydrocarbon solvents and unsaturated hydrocarbon solvents may be used alone or in combination. One or more solvents are preferably present in an amount of from about 3 to about 40% by weight, more preferably from about 5 to about 20% by weight, and most preferably from about 8 to about 12% by weight.

[0023] The W / O emulsion composition of the present invention, including products for cleaning and / or polishing furniture, shoes, and automobiles, contains at least one nonionic emulsifier for forming an emulsion. An emulsion is a stable mixture of two or more immiscible liquids held in suspension with a small proportion of a substance called an emulsifier. All W / O emulsions are characterized by a continuous oil phase and a discontinuous aqueous phase dispersed throughout the continuous oil phase.

[0024] Suitable nonionic emulsifiers for use generally include those used in furniture care products, shoe care products, and car care products. Such conventional emulsifiers may be used alone or in combination. Preferred emulsifiers for use have a hydrophilic-lipophilic balance (HLB) value of from about 2 to about 6.

[0025] Examples of nonionic emulsifiers useful alone or in combination include, but are not limited to, sorbitan esters of oleic acid and lauric acid, polyethoxylated sorbitan esters having 20 or fewer ethoxy units, monoglycerides and diglycerides of adipogenic fatty acids, and combinations thereof.

[0026] Additional examples of any commercially available nonionic emulsifiers include emulsifiers sold under the "SPAN" (trade name) and "TWEEN" (trade name), currently commercially available from Croda Inc. Specific examples of such emulsifiers include sorbitan monooleate, sorbitan monolaurate, and sorbitan monopalmitate. Mixtures of the various emulsifiers described above may also be utilized.

[0027] At least one nonionic emulsifier is preferably present in an amount of from about 0.01 to about 5% by weight, more preferably from about 0.1 to about 2% by weight, and most preferably from about 0.1 to about 1% by weight.

[0028] The water component that constitutes the liquid phase of the emulsion may be deionized water, reverse osmosis water, distilled water, tap water, etc. Water constitutes the balance based on 100% by weight of the emulsifying composition and is preferably present in an amount of from about 10 to less than 100% by weight, more preferably from about 50 to about 95% by weight, and most preferably from about 70 to about 90% by weight.

[0029] The emulsifying composition of the present invention may also contain one or more specific optional materials. Film-forming agents suitable for use in the present invention include silicones and waxes. They can provide enhanced shine / gloss on the surface.

[0030] Silicones useful in the present invention have a viscosity of about 5 to about 5,000 centistokes (cSt) (about 5×10 -6 ~about 5×10 -3 m 2 / s), preferably about 100 to 1000 cSt (about 1×10 -4 ~1×10 -3 m 2It contains a low-viscosity silicone fluid having a viscosity of ( / s).

[0031] The silicone useful in the present invention may be substituted with any organic group known in silicone technology. Of further note is silicone gum. Silicone gum generally refers to high-molecular-weight linear polysiloxanes or silicones that can be converted from their highly plastic state to a mainly elastic state by crosslinking.

[0032] The silicone component is preferably present in an amount of from about 0.1 to about 20% by weight, more preferably from about 1 to about 11% by weight, and most preferably from about 3 to about 7% by weight. Conventional waxes suitable for use include, but are not limited to, certain synthetic waxes such as microcrystalline wax and petroleum wax, and certain natural waxes such as "carnauba" wax. The wax component is preferably present in an amount of from about 0.05 to about 2.0% by weight of wax, preferably from about 0.05 to about 0.5% by weight of wax, based on the total weight of the emulsion composition.

[0033] One or more of the following additional known additives may be added to the emulsion composition, including but not limited to solvents, surfactants, fragrance components, preservatives, and colorants. The emulsion may contain a solvent to enhance its detergency. Examples of solvents suitable for use include, but are not limited to, oxygenated solvents such as ethyl alcohol.

[0034] The emulsion may contain a surfactant to enhance its detergency. Examples of surfactants suitable for use include anionic surfactants, cationic surfactants, and amphoteric surfactants.

[0035] Examples of useful anionic surfactants include, but are not limited to, certain alkali metal alkyl sulfates (e.g., sodium lauryl sulfate) and alkali metal alkyl ether sulfates, sulfosuccinates containing an attached polyethylene glycol moiety, and alkylaryl sulfonates. Mixtures of these surfactants may also be utilized in the present invention.

[0036] Examples of suitable cationic surfactants for use include quaternary ammonium halides, certain quaternary ammonium compounds such as quaternary ammonium sulfates, so-called "fatty" amines ethoxylated with from about 2 to about 10 moles of ethylene oxide, and acetate or chloride salts of such amines. Various mixtures or combinations of the foregoing surfactants may also be utilized.

[0037] Examples of suitable amphoteric surfactants include, but are not limited to, cocamidopropyl betaine. When an amphoteric surfactant is included in the emulsion system, this amphoteric compound may function simultaneously as a freeze-thaw stabilizer. Additional freeze-thaw stabilizers may not be necessary to enable freeze-thaw stability.

[0038] Fragrance components are understood to include one or more of the fragrances or perfumes that impart the desired scent, or mixtures thereof. Conventional fragrance components suitable for use are well known to those skilled in the art and are therefore not described in detail herein. The fragrance components are typically present in an amount effective to impart the desired scent intensity and may be, for example, preferably in the range of from about 0.01 to about 10% by weight, more preferably from about 0.01 to about 1% by weight of the emulsion composition.

[0039] Commercially available preservatives may be included to extend the shelf life of the emulsion composition, such as bronopol (2-bromo-2-nitropropane-1,3-diol), which is sold, for example, as PROTECTOL BN (trade name) by BASF and BIOBAN BP-PLUS (trade name) by The Dow Chemical Company. The preservative may preferably be present in an amount of from about 0.001 to about 5% by weight.

[0040] The furniture care emulsion product, shoe care emulsion product, or vehicle care emulsion product containing at least one freeze-thaw stabilizer of the present invention is an aerosol or non-aerosol such as a pump spray, trigger spray, pour bottle, or squeeze bottle.

[0041] The aerosol furniture care product, shoe care product, or vehicle care product contains an intermediate composition of a W / O type emulsion composition and a propellant. The propellant may be, for example, a compressed gas propellant such as nitrogen, air, carbon dioxide, nitrous oxide, argon, or a mixture thereof, or one or more of a hydrocarbon (e.g., butane, propane, isobutane, and mixtures thereof), dimethyl ether, methyl ethyl ether, etc., which are liquids or liquefied petroleum gas (LPG) whose use has been conventionally known. One or more propellants are present in the product in an amount of about 0.1 to about 25% by weight based on the total aerosol formulation composition. The compressed gas propellant is generally present in a lower range of about 0.1 to about 2% by weight, more preferably about 0.5 to about 1% by weight. The LPG propellant is present in a higher range of about 4 to about 25% by weight, more preferably about 6 to about 15% by weight.

[0042] Some base formulations of the W / O type emulsion are shown below. They are generally commonly found in furniture care products, shoe care products, and vehicle care products. These base formulations do not contain a freeze-thaw stabilizer.

[0047]

Table 5

[0048] The freeze-thaw stabilizer of the present invention was added to the above-mentioned formulation bases A to E at selected concentrations. These test samples were prepared by filling a glass container with the base formulation and the selected freeze-thaw stabilizer. Next, the test samples were stored in a freezer at -18°C for at least 12 hours. Next, the test samples were thawed at room temperature (i.e., about 22°C) for at least 6 hours or until the temperature of the test samples reached room temperature. The test samples were inspected. When the emulsion broke, it was examined whether the emulsion could be reformed by shaking the test sample by hand. The test results are summarized in Table 1 below.

[0049]

Table 6

[0050] Test samples 1 to 8 were designed to demonstrate the effectiveness of the freeze-thaw stabilizer of the present invention. These test samples contain the formulation of base A. Base A contains all three essential components essential for the formation of a W / O type emulsion. Base A is not stable to freeze-thaw. After base A passed through the freeze-thaw cycle, the emulsion broke and could not be reformed even by shaking the container. However, by adding one of the following freeze-thaw stabilizers: glycerin, ethylene glycol, D-sorbitol, sucrose, glucose, DMSO, and lauryl dimethylamine oxide, freeze-thaw stability was imparted to base A.

[0051] Test samples 9 to 19 were designed to demonstrate that the freeze-thaw stabilizer of the present invention can function in various emulsion systems containing any components. Test samples 9 to 10 contain the formulation of base B. The formulation of base B contains silicone 100 cSt as an optional film-forming agent. Base B is not stable against freeze-thaw, but when 1.0 wt% of glycerin was added to base B, the emulsion could be reformed easily by simple shaking after the destruction of the emulsion.

[0052] Test samples 11 to 12 contain the formulation of base C. The formulation of base C contains sodium lauryl sulfate as an optional anionic surfactant. Base C is not stable against freeze-thaw, but when 2.0 wt% of glycerin was added to base C, test sample 12 was prevented from the destruction of the emulsion after the freeze-thaw cycle.

[0053] Test samples 13 to 14 contain the formulation of base D. The formulation of base D contains ethanol as an optional solvent. Base D is not stable against freeze-thaw, but when 1.0 wt% of glycerin was added, test sample 14 could reform the emulsion easily by simple shaking after the destruction of the emulsion.

[0054] Test samples 15 to 19 contain the formulation of base E. The formulation of base E contains two or more hydrocarbon solvents and an optional fragrance. When 0.5 wt% glycerin was added to base E, the emulsion was still broken after the freeze-thaw test. However, at this same concentration, glycerin enabled freeze-thaw stability in base A (see Test No. 2). After increasing the concentration of glycerin to 1.0 wt% in the formulation of base E, the emulsion was reformed by simply shaking. This indicates that the minimum concentration of stabilizer for reforming the emulsion after it has broken in the freeze-thaw cycle can vary for each different emulsification system. When the concentration of glycerin was further increased to 3.0 wt% in the formulation of base E, the emulsion was stable after the freeze-thaw cycle. This indicated that there is another critical concentration at which the stabilizer can prevent the destruction of the emulsion. In Test Sample 19, two freeze-thaw stabilizers were used together. Glycerin was included at 1.0 wt% and D-sorbitol was included at 2.0 wt%. Such freeze-thaw stabilizers prevented the destruction of the emulsion after the freeze-thaw cycle.

[0055] Preferred aerosol formulation examples of the present invention are shown below.
