Description

[Technical Field]

[0001] The present invention relates to a cleaning product comprising a spray dispenser and a cleaning composition that is more stable and also improves the cleaning of crystalline lipids. [Background technology]

[0002] Dishwashing detergents have long been used to facilitate the removal of grease, oil, and crystalline fats from cookware, dishes, and kitchen utensils. Conventional dishwashing detergents are generally available in liquid form and are effective at removing a wide range of food residues.

[0003] In recent years, there has been a growing demand for convenient and efficient dishwashing products that provide a quick and effective cleaning solution. In response to this demand, dishwashing sprays have gained popularity as a convenient and time-saving alternative to traditional dishwashing methods. Dishwashing sprays typically consist of a liquid detergent composition contained in a container equipped with a manually operated spray nozzle. When the nozzle is activated, the detergent is dispensed as a fine mist or spray, allowing for targeted application to soiled dish surfaces. The user can then scrub the treated surface to loosen and remove food residue. However, for improved convenience and efficiency, it is desirable that the spray composition solubilizes and "lifts off" greasy stains with little to no scrubbing required.

[0004] Dishwashing detergent sprays provide convenience and ease of use, but face challenges when it comes to effectively removing crystalline fats. Crystalline fats such as beef fat, lard, and other animal fats can be particularly stubborn and difficult to remove. Crystalline fats are resistant to normal dishwashing detergents due to their surface tension and adhesion properties, resulting in either incomplete or unsatisfactory cleaning, or the need for more manual effort. Compositions containing high concentrations of anionic surfactants, such as alkyl ethoxylated sulfate surfactants, are particularly effective at removing liquid grease stains. However, the spray droplets (over-spray) of such anion-rich compositions are highly likely to cause irritation to the nose and eyes. Formulating the spray detergent composition to be non-ionic-rich, with limited or no anionic surfactant, results in spray droplets that are less irritating to the nasal passages and eyes. However, such compositions have a significantly lower ability to lift crystalline fats without almost no or no scrubbing.

[0005] To address this problem, a solvent is incorporated into the dishwashing detergent spray to facilitate the removal of crystalline fats. Hydrophobic solvents such as tripropylene glycol n-butyl ether are particularly effective at dissolving and dispersing fat molecules, allowing fat molecules to be more easily removed without almost no or no scrubbing.

[0006] Such solvents are particularly effective in removing crystalline fats, but are difficult to stably incorporate into detergent compositions, especially those for hand dish spray applications having a relatively low viscosity and a relatively low concentration of surfactant. Such hydrophobic solvents can affect the viscosity, surface tension, and emulsion stability of the composition, and may cause phase separation, sedimentation, or a reduction in shelf life. Detergent spray compositions with low stability can result in performance degradation, poor spray patterns, nozzle clogging, or limited shelf life, which can limit the commercial viability and consumer acceptance of such products. Hydrophobic solvents can be solubilized by the use of co-solvents. However, such co-solvents have typically been found to reduce the effectiveness of hydrophobic solvents.

[0007] By formulating spray detergent compositions to be rich in nonionic surfactants, particularly alkyl polyglucosides, while limiting the level of anionic surfactants, the removal of amorphous fatty and oily residues can be improved. However, stably formulating a hydrophobic solvent such as tripropylene glycol n-butyl ether is even more difficult when the detergent composition contains little or only a low concentration of anionic surfactant.

[0008] Typically, a high pH is used to improve fat removal efficacy. However, many fragrance components have low chemical or physical stability at high pH, so high pH is typically detrimental to fragrance stability.

[0009] Therefore, there is a need for an improved dishwashing detergent spray composition that effectively removes crystalline fats, especially at a more neutral pH, and provides spray droplets that are less irritating to the nasal passages and eyes, without compromising the stability and functionality of the spray detergent.

[0014] The present invention relates to a cleaning product comprising a spray dispenser and a cleaning composition, the composition being housed in the spray dispenser, the cleaning composition being a surfactant system of 2% to 25% by weight of the composition, comprising an alkyl polyglucoside surfactant; an auxiliary surfactant selected from amphoteric surfactants, zwitterionic surfactants, and mixtures thereof; and less than 3% by weight of an anionic surfactant in the cleaning composition, a glycol ether solvent, of formula (I): R 1 O(R 2 O)3R 3 (wherein R 1 is linear or branched C4, C5, or C6 alkyl or substituted or unsubstituted phenyl, R 2 is ethyl or propyl, and R 3 is hydrogen or methyl) of glycol ether solvent, and of formula (II): R 4 O(R 5 O)3R 6 (wherein R 4 is methyl or ethyl, R 5 is ethyl or propyl, and R 6 is hydrogen or methyl) of glycol ether solvent, comprising a glycol ether solvent, the composition comprising 1.0% to 15% by weight of the glycol ether solvent of the total composition, the composition comprising the glycol ether solvent of formula (I) and the glycol ether solvent of formula (II) in a weight ratio of less than 2.5:1, relates to a cleaning product.

Mode for Carrying Out the Invention

[0015] The need for cleaning products, including spray dispensers and cleaning compositions, that improve the cleaning of crystalline fats without compromising the stability of the formulation is met by formulating a cleaning composition that includes a surfactant system, in combination with a solvent system, a surfactant system containing an alkyl polyglucoside surfactant and an auxiliary surfactant, which is an amphoteric and / or zwitterionic surfactant, while limiting the amount of anionic surfactant present, as described herein. Such cleaning compositions have been found to better improve the softening of crystalline fats and thus help to remove them from tableware articles being processed. Furthermore, since this detergent composition is contained in a spray container, the composition can be uniformly applied to the surface of an article and left for a certain period of time as part of a pretreatment step before the main cleaning step to further loosen the crystalline fats.

[0016] The present invention relates to a cleaning product for hand-washing dishes, and this product comprises a spray dispenser and a cleaning composition. The cleaning composition is contained in the spray dispenser.

[0017] For the purposes of this invention, “tableware” encompasses all articles used for cooking or for serving and eating food.

[0018] In this specification, "spray dispenser" means a container comprising a housing for containing a composition and means for spraying the composition. A preferred spraying means is a trigger spray. The compositions used in this invention foam when sprayed onto the surface to be treated.

[0019] Cleaning composition: The cleaning composition is preferably a dishwashing cleaning composition, and is preferably in liquid form. This cleaning composition is suitable for spraying.

[0020] The pH of the composition may be 6 or higher, more preferably 6 to 12, and most preferably 6.5 to 8.0, when measured undiluted at 20°C. Typically, a higher pH is desirable to improve the removal of liquid fats. However, it has been found that the more neutral pH of this composition improves the removal of crystalline fats, especially when scrubbing is limited. Furthermore, fragrance compositions typically have low stability at higher pH levels; therefore, formulating the composition using a more neutral pH can improve the fragrance.

[0021] The cleaning product according to the present invention may include a composition having a Newtonian viscosity of, for example, 1 mPa·s to 50 mPa·s, preferably 1 mPa·s to 20 mPa·s, and more preferably 1 mPa·s to 10 mPa·s at 20°C, as measured using the method defined herein.

[0022] Alternatively, the cleaning product according to the present invention may include a composition having a shear-reducing rheological profile, for example, 1000s at 20°C. -1 When measured at a shear rate of , it can have a high shear viscosity of 1 mPa·s to 50 mPa·s, preferably 1 mPa·s to 20 mPa·s, more preferably 5 mPa·s to 15 mPa·s, and furthermore, using the method defined herein, at 20°C for 0.1 s -1 When measured, it has a low shear viscosity of 100 mPa·s to 1,000 mPa·s, preferably 200 mPa·s to 500 mPa·s.

[0023] Preferably, the cleaning composition used in the present invention has a certain Newtonian viscosity.

[0024] This liquid cleaning composition typically contains an aqueous carrier in which all other active ingredients are dissolved or ultimately dispersed. In this case, water may be present in an amount of 60% to 90% by weight, preferably 75% to 85% by weight, of the composition.

[0025] The liquid cleaning composition contains a surfactant system and a glycol ether solvent system.

[0026] The surfactant and glycol ether solvent are preferably present in a weight ratio of 3:1 to 1:3, preferably 1.5:1 to 1:2, and most preferably 1:1 to 1:1.5. Compositions used in the present invention having such a weight ratio of surfactant to glycol ether solvent have been found to improve tableware coating while minimizing spray droplets (residual spray droplets remaining dispersed in the air). Therefore, such spray compositions reduce waste and minimize the amount of spray droplets that may be inhaled.

[0027] Surfactant-based: The composition contains a surfactant system in an amount of 2% to 20% by weight, preferably 3% to 15% by weight, and more preferably 3.5% to 8.0% by weight of the composition. This surfactant system contains an alkyl polyglucoside surfactant. This surfactant system contains an auxiliary surfactant selected from the group consisting of amphoteric surfactants, zwitterionic surfactants, and mixtures thereof, preferably selected from amphoteric surfactants, and more preferably selected from amine oxide surfactants. The alkyl polyglucoside surfactant and the auxiliary surfactant may be present in a weight ratio of 10:1 to 1:10 or greater, preferably 5:1 to 1:5, and most preferably 2:1 to 1:2.

[0028] Alkyl polyglucoside surfactants: The surfactant system preferably contains alkyl polyglucoside ("APG") at a concentration of 0.5% to 10% by weight, preferably 1.0% to 5.0% by weight, and more preferably 1.5% to 3.0% by weight of the composition.

[0029] For the purpose of improving the removal of crystalline lipids, alkyl polyglucoside surfactants may have an average degree of polymerization of 0.1 to 3.0, preferably 1.0 to 2.0, most preferably 1.2 to 1.6, and a number-average alkyl carbon chain length of 8 to 18, preferably 10 to 16, most preferably 12 to 14.

[0030] To improve initial foaming, alkyl polyglucoside surfactants may have an average degree of polymerization of 0.1 to 3.0, preferably 1.0 to 2.0, most preferably 1.2 to 1.6, and a number-average alkyl carbon chain length of 8 to 18, preferably 8 to 14, most preferably 8 to 10.

[0031] C8-C18 alkyl polyglucosides are commercially available from several suppliers (e.g., Simusol® surfactant from Seppic Corporation; and Glucopon® 600CSUP, Glucopon® 650EC, Glucopon® 600CSUP / MB, and Glucopon® 650EC / MB from BASF Corporation).

[0032] auxiliary surfactants: This auxiliary surfactant is selected from the group consisting of amphoteric surfactants, zwitterionic surfactants, and mixtures thereof. The cleaning composition may contain the auxiliary surfactant at a concentration of 0.5 to 7.5% by weight, preferably 1.0% to 5.0% by weight, and more preferably 1.5% to 3.0% by weight of the composition.

[0033] Amphoteric surfactants: As mentioned above, amine oxide surfactants are preferred for use as auxiliary surfactants. Amine oxide surfactants may be linear or branched, but linear is preferred. Preferred linear amine oxides are typically water-soluble and characterized by the formula R1-N(R2)(R3)O (wherein R1 is a C8-18 alkyl group, and the R2 and R3 portions are selected from the group consisting of C1-3 alkyl groups, C1-3 hydroxyalkyl groups, and mixtures thereof). For example, R2 and R3 can be selected from the group consisting of methyl, ethyl, propyl, isopropyl, 2-hydroxyethyl, 2-hydroxypropyl, and 3-hydroxypropyl, and mixtures thereof, but it is preferable that one or both of R2 and R3 are methyl. Examples of linear amine oxide surfactants include linear C10-C18 alkyldimethylamine oxide and linear C8-C12 alkoxyethyl dihydroxyethylamine oxide.

[0034] Preferably, the amine oxide surfactant is selected from the group consisting of alkyldimethylamine oxide, alkylamidopropyldimethylamine oxide, and mixtures thereof. C8-18 alkyldimethylamine oxide or alkyldimethylamine oxide such as C10-16 alkyldimethylamine oxide (cocodimethylamine oxide, etc.) is preferred. Suitable alkyldimethylamine oxides include C10 alkyldimethylamine oxide surfactants, C10-12 alkyldimethylamine oxide surfactants, C12-C14 alkyldimethylamine oxide surfactants, and mixtures thereof. C12-C14 alkyldimethylamine oxide is particularly preferred.

[0035] Suitable alternative amine oxide surfactants include medium-branched amine oxide surfactants. As used herein, “medium-branched” means that the amine oxide has one alkyl moiety having n1 carbon atoms, and one alkyl branch in the alkyl moiety has n2 carbon atoms. The alkyl branch is located on the nitrogen to alpha carbon on the alkyl moiety. This type of branching of amine oxide is also known in the art as internal amine oxide. The sum of n1 and n2 may be 10 to 24, preferably 12 to 20, more preferably 10 to 16 carbon atoms. The number of carbon atoms in one alkyl moiety (n1) is preferably the same as or similar to the number of carbon atoms in one alkyl branch (n2), so that the alkyl moiety and its alkyl branch are symmetrical. As used herein, “symmetric” means that in at least 50% by weight, more preferably at least 75% to 100% by weight, of the branched amine oxide used herein, the |n1-n2| group consists of 5 or fewer carbon atoms, preferably 4, and most preferably 0 to 4 carbon atoms. The amine oxide further comprises two portions independently selected from C1-3 alkyl, C1-3 hydroxyalkyl, or polyethylene oxide groups containing about 1 to about 3 ethylene oxide groups on average. Preferably, these two portions are selected from C1-3 alkyl, and more preferably, both are selected as C1 alkyl.

[0036] Alternatively, the amine oxide surfactant may be a mixture of amine oxides, including a mixture of low-cut amine oxides and mid-cut amine oxides. Therefore, the amine oxides in the composition of the present invention are a) A low-cut amine oxide of formula R1R2R3AO in an amount of approximately 10% to approximately 45% by weight of amine oxide, where R1 and R2 are independently selected from hydrogen, C1-C4 alkyl, or mixtures thereof, and R3 is selected from C10 alkyl and mixtures thereof. b) The amine oxide may contain 55% to 90% by weight of a midcut amine oxide of formula R4R5R6AO (wherein R4 and R5 are independently selected from hydrogen, C1-C4 alkyl, or mixtures thereof, and R6 is selected from C12-C16 alkyl, or mixtures thereof).

[0037] In the low-cut amine oxides preferred for use herein, R3 is n-decyl, and preferably both R1 and R2 are methyl. In the mid-cut amine oxide of formula R4R5R6AO, preferably both R4 and R5 are methyl.

[0038] Preferably, the amine oxide comprises less than about 5% by weight, more preferably less than 3% by weight, of an amine oxide of formula R7R8R9AO (wherein R7 and R8 are selected from hydrogen, C1-C4 alkyl groups and mixtures thereof, and R9 is selected from C8 alkyl groups and mixtures thereof). Limiting the amount of amine oxide of formula R7R8R9AO improves both physical stability and foaming persistence.

[0039] Zwitterionic surfactants: In the compositions of the present invention, it has been found that the removal of polymerized or "burnt-on" grease is improved by using a zwitterionic surfactant as an auxiliary surfactant. Suitable zwitterionic surfactants include betaine surfactants. Such betaine surfactants include alkylbetaine, alkylamidebetaine, amideazoliniumbetaine, sulfobetaine (INCI sultaine), and phosphobetaine, which preferably satisfy formula (II): R 1 -[CO-X(CH2) n ] x -N + (R 2 )(R3)-(CH2) m -[CH(OH)-CH2] y -Y - In formula (II), R1 is selected from the group consisting of saturated or unsaturated C6-22 alkyl residues, preferably C8-18 alkyl residues, more preferably saturated C10-16 alkyl residues, and most preferably saturated C12-14 alkyl residues. X is selected from the group consisting of NH, NR4 (wherein R4 is a C1-4 alkyl residue), O, and S. n is an integer between 1 and 10, preferably between 2 and 5, more preferably between 3. x is 0 or 1, preferably 1. R2 and R3 are independently selected from the group consisting of C1-4 alkyl residues, substituted hydroxyl such as hydroxyethyl, and mixtures thereof, preferably both R2 and R3 are methyl. m is an integer between 1 and 4, preferably 1, 2, or 3. y is either 0 or 1. Y is selected from the group consisting of COO, SO3, OPO(OR5)O, or P(O)(OR5)O (wherein R5 is H or C1-4 alkyl residues).

[0040] Preferred betaines are alkylbetaine of formula (Ia), alkylamidopropylbetaine of formula (Ib), sulfobetaine of formula (Ic), and amidesulfobetaine of formula (Id):

[0041] [ka] In the formula, R1 has the same meaning as in formula (II). Particularly preferred are the carbobetaines of formulas (Ia) and (Ib) [i.e., in formula (II), Y- is COO-], and more preferred is the alkylamide betaine of formula (Ib).

[0042] Preferred betaines can be selected from the group consisting of capryl / capramidopropyl betaine, cetyl betaine, cetylamidopropyl betaine, cocamidoethyl betaine, cocamidopropyl betaine, cocobetaine, decyl betaine, decylamidopropyl betaine, hydrogenated taro betaine / amidopropyl betaine, isostearamidopropyl betaine, lauramidopropyl betaine, lauryl betaine, myristylamidopropyl betaine, myristyl betaine, oleadopropyl betaine, oleyl betaine, palmamidopropyl betaine, palmitoamidopropyl betaine, palm kernelamidopropyl betaine, stearamidopropyl betaine, stearyl betaine, taroamidopropyl betaine, taro betaine, undecylenamidopropyl betaine, undecyl betaine, and mixtures thereof, or [named according to INCI]. Preferred betaines are selected from the group consisting of cocamidopropyl betaine, cocobetaine, lauramidopropyl betaine, lauryl betaine, myristylamidopropyl betaine, myristyl betaine, and mixtures thereof. Cocamidopropyl betaine is particularly preferred.

[0043] Anionic surfactants: If the detergent composition contains an anionic surfactant, suitable anionic surfactants include, but are not limited to, surfactant compounds containing an organic hydrophobic group generally containing 8 to 22 carbon atoms or generally 8 to 18 carbon atoms in its molecular structure, and at least one water-soluble group preferably selected from sulfonates, sulfates, and carboxylates to form a water-soluble compound. Typically, the hydrophobic group contains a linear or branched C8-C22 alkyl or acyl group. Such surfactants are used in the form of water-soluble salts, and the salt-forming cation is usually selected from sodium, potassium, ammonium, magnesium, and mono-, di-, or tri-alkanolammonium, with sodium being the most commonly selected cation.

[0044] Since anionic surfactants are undesirable in the compositions used in the present invention, the surfactant system contains less than 3.0% by weight of anionic surfactant, preferably less than 2.0% by weight, and more preferably less than 1.0% by weight of anionic surfactant in the detergent composition. Most preferably, the detergent composition according to the present invention does not contain anionic surfactant.

[0045] Further nonionic surfactants: This surfactant system may further contain a nonionic surfactant. If present, the surfactant system may contain an additional nonionic surfactant in an amount of 0.5% to 12% by weight, preferably 1.0% to 7.0% by weight, and more preferably 2.0% to 6.0% by weight of the composition.

[0046] Further suitable nonionic surfactants include alkylalkoxylated nonionic surfactants, and more preferably ethoxylated nonionic surfactants. Suitable nonionic surfactants include condensation products of an aliphatic alcohol and 1 to 25 moles of ethylene oxide. The alkyl chain of the aliphatic alcohol may be linear or branched, substituted or unsubstituted, and is preferably linear.

[0047] This further nonionic surfactant is preferably a low-cut alkyl ethoxylate surfactant. Examples of low-cut alcohol ethoxylate surfactants include alcohol ethoxylate surfactants having an average alkyl carbon chain length of C10 or less. More preferably, this alkyl ethoxylate surfactant has an average alkyl chain length of C5 to C8, preferably C5 to C7, and a number-average ethoxylation degree of 1 to 10, preferably 3 to 8, more preferably 4 to 6. Suitable nonionic alcohol ethoxylate surfactants include commercially available materials such as Emulan® HE50 or Lutensol® CS6250 (available from BASF).

[0048] Other suitable nonionic surfactants for use in this specification may be selected from fatty alcohol polyglycol ethers, fatty acid glucamides, and mixtures thereof.

[0049] Most preferably, this surfactant system comprises an alkyl polyglucoside surfactant, an amine oxide surfactant, and an alkyl ethoxylate surfactant, particularly a low-cut alcohol ethoxylate surfactant, as described above.

[0050] Other surfactants: The compositions used in the present invention preferably do not contain cationic surfactants, and in particular do not contain antimicrobial cationic surfactants. This is because such surfactants are typically detrimental to degreasing and surface gloss. Examples of such antimicrobial cationic surfactants include quaternary ammonium compounds such as dodecyldimethylammonium chloride, alkyldimethylbenzylammonium chloride, alkyldimethylethylbenzylammonium chloride, and mixtures thereof.

[0051] Glycol ether solvent: The glycol ether solvent combinations described herein have been found to provide stable compositions when used in combination with alkyl polyglucosides, and are particularly effective in removing crystalline lipids even at more neutral pH levels. Specifically, the compositions comprise a glycol ether solvent, the glycol ether solvent is a. Equation (I): R 1 O(R 2 O)3R 3 (In the formula, R 1 R is a linear or branched C4, C5, or C6 alkyl or substituted or unsubstituted phenyl, 2 is ethyl or propyl, for example isopropyl, and R 3 (is hydrogen or methyl) glycol ether solvent, and b.Formula (II):R 4 O(R 5 O)3R 6 (In the formula, R4 is methyl or ethyl, and R 5 is ethyl or propyl, for example isopropyl, and R 6 The solvent contains a glycol ether solvent (which is hydrogen or methyl).

[0052] The glycol ether solvent of formula (I) is particularly effective in removing crystalline fat from dishes with little to no scrubbing. Such solvents are considered effective in removing crystalline fat because they are hydrophobic. However, because such solvents are hydrophobic, they are difficult to formulate into aqueous detergent compositions, especially those suitable for spraying, because such compositions typically have low viscosity and relatively low concentrations of surfactants. Furthermore, they typically have poor stability in compositions containing only low or no anionic surfactants. For such solvents, it is typically necessary to incorporate a co-solvent into the composition to stably formulate the solvent of formula (I). However, it has been found that solubilizing the solvent of formula (I) reduces its effectiveness in removing crystalline fat from dishes.

[0053] In the present invention, the glycol ether solvent of formula (II) is incorporated into the formulation to stabilize the glycol ether solvent of formula (I), but the effect of the solvent on the fat-removing efficacy is negligible.

[0054] In the glycol ether solvent of formula (I), aR 1 Preferably, it is a linear or branched C4 or C5, preferably a linear or branched C4, more preferably a linear butyl. bR 2 The compound is preferably propyl, more preferably isopropyl. cR 3 It is preferably hydrogen.

[0059] The composition comprises a glycol ether solvent of formula (I) and a glycol ether solvent of formula (II) in a weight ratio of less than 2.5:1, preferably 1:1 to 2.25:1, and more preferably 1.25:1 to 2.0:1. When formulated in the aforementioned ratios, the stability of the glycol ether solvent of formula (I) in a composition containing little to no anionic surfactant is particularly improved without affecting the crystalline lipid-removing efficacy of the composition.

[0060] Further optional ingredients: Fragrance: The composition preferably contains a fragrance. The fragrance may be present in a concentration of 0.05% to 2.5% by weight, preferably 0.1% to 2.0% by weight, and more preferably 0.3% to 1.0% by weight of the composition. As previously mentioned, there are several fragrance components, particularly those derived from natural extracts, which are typically not stable at high pH levels. Examples of such fragrance components include essential oils such as lemon, lime, orange, and patchouli, which typically contain volatile compounds that can decompose or evaporate at high pH. Flower extracts such as rose, lavender, and jasmine are also typically sensitive to alkaline conditions and may lose their aroma or undergo chemical changes at high pH levels. Fragrance esters, aldehydes, and ketones also undergo chemical reactions or decomposition at high pH, ​​resulting in loss of scent or alteration of their aroma profile. Some natural resins, such as benzoin or myrrh, lose their solubility or undergo chemical changes at high pH, ​​affecting their fragrance properties.

[0061] Since the compositions of the present invention are effective at a more neutral pH, the compositions preferably contain a fragrance, and preferably the fragrance comprises a fragrance component selected from essential oils, flower extracts, fragrance esters, fragrance aldehydes, fragrance ketones, and mixtures thereof.

[0062] Further organic solvents: The composition may further contain, in an amount of 0.01% to 5% by weight, an organic solvent selected from the group consisting of C2-C4 alcohols, C2-C4 polyols, polyalkylene glycols, particularly polypropylene glycols having a weight-average molecular weight of 1500-4000, and mixtures thereof.

[0069] The salt cation is preferably selected from alkali metals, alkaline earth metals, monoethanolamine, diethanolamine, or triethanolamine, and mixtures thereof, and is preferably sodium.

[0070] If present, carboxylic acids or their salts are preferably present in a concentration of 0.05% to 5% by weight, more preferably 0.1% to 1% by weight, of the total composition.

[0071] Hydrotrope The composition according to the present invention may further contain a hydrotrope. Preferably, the hydrotrope is selected from cumenesulfonate, xylenesulfonate, toluenesulfonate, and most preferably sodium-neutralized cumenesulfonate. If present, the hydrotrope is incorporated into the detergent composition in an amount of 0.1% to 5% by weight, preferably 0.25% to 3% by weight, and most preferably 0.5% to 2% by weight.

[0072] Shear viscosity reducing rheological modifiers: The composition according to the present invention further comprises a rheology modifier, which can provide the product with a shear-thickening rheology profile. By incorporating a rheology-modifying polymer, the particle size distribution of the resulting spray can be improved, and the stinging sensation of the spray droplets can also be reduced. Preferably, the rheology modifier is an amorphous polymer rheology modifier. This polymer rheology modifier may be a synthetic or naturally derived polymer.

[0073] Examples of naturally derived polymer structuring agents used in the present invention include hydroxyethylcellulose, hydrophobically modified hydroxyethylcellulose, carboxymethylcellulose, polysaccharide derivatives, and mixtures thereof. Examples of polysaccharide derivatives include, but are not limited to, pectin, alginates, arabinogalactan (gum arabic), carrageenan, karaya gum, tragacanth gum, gellan gum, xanthan gum, and guar gum. Examples of synthetic polymer structuring agents used in the present invention include polymers and copolymers containing polycarboxylates, polyacrylates, polyurethanes, polyvinylpyrrolidone, polyols, and derivatives and mixtures thereof. Alternatively, the compositions used in the present invention may contain polyethylene oxide (PEO) polymers.

[0074] Preferably, the composition according to the present invention comprises a rheology-modified polymer of natural origin, most preferably a rheology-modified polymer selected from xanthan gum, polyethylene oxide, or a mixture thereof.

[0075] Generally, rheology-modified polymers are included in the composition at concentrations of 0.001% to 1% by weight, alternatively 0.01% to 0.5% by weight, and more alternatively 0.05% to 0.25% by weight.

[0076] Other ingredients: The compositions of the present invention may include cleaning amines such as cyclic cleaning amines. The term “cyclic diamine” as used herein encompasses a single cleaning amine and mixtures thereof. The amine may be protonated depending on the pH of the cleaning medium in which it is used. Particularly preferred for use herein are cyclic diamines selected from the group consisting of 1,3-bis(methylamine)-cyclohexane, 2-methylcyclohexane-1,3-diamine, 4-methylcyclohexane-1,3-diamine, and mixtures thereof. 1,3-bis(methylamine)-cyclohexane is particularly preferred for use herein. A mixture of 2-methylcyclohexane-1,3-diamine and 4-methylcyclohexane-1,3-diamine is also preferred for use herein.

[0077] The composition may also contain pH adjusters and / or buffers such as sodium hydroxide, alkanolamines including monoethanolamine, and inorganic bicarbonates. The composition may further contain trace components selected from preservatives, UV stabilizers, antioxidants, fragrances, colorants, and mixtures thereof.

[0078] Spray dispenser: The spray dispenser comprises a reservoir for containing the composition of the present invention and a spraying means. Suitable spray dispensers include hand pump (sometimes called a "trigger") devices, pressurized can devices, and electrostatic spray devices. Preferably, the spray dispenser is unpressurized and the spraying means is of the trigger type. The reservoir is typically a container such as a bottle, more typically a plastic bottle.

[0079] The cleaning product of the present invention comprises a cleaning composition. This cleaning composition is typically suitable for spraying ("direct application") from a spray dispenser onto the surface of the tableware to be treated. The composition preferably forms foam on the surface immediately after application without requiring any additional physical intervention (e.g., rubbing by hand).

[0080] A spray dispenser typically includes a trigger lever, which, when pressed, activates a small pump. The main drive of the pump is typically a piston, housed within a cylinder and pressed against a spring. Pressing the trigger pushes the piston into the cylinder, pressing against the spring, which compresses the spring and pushes the composition contained within the pump out of the nozzle. When the trigger lever is released, the spring pushes the piston back, expanding the cylinder area and refilling the pump by drawing the composition from a reservoir, typically through a one-way valve. This pump is typically attached to a tube that draws the composition from the reservoir to the pump. A spray dispenser may also include a further one-way valve located between the pump and the nozzle.

[0081] The nozzle includes an orifice into which the composition is dispensed. The nozzle utilizes the kinetic energy of the composition to divide it into droplets as it passes through the orifice. A suitable nozzle may be simple, molded, or include a swirl chamber immediately before the orifice. Such a swirl chamber induces rotational fluid motion of the composition, causing it to swirl within the chamber. A film is released from the outer periphery of the orifice, and typically, the composition is dispensed from the orifice as finer droplets.

[0082] Since such a trigger-operated spray dispenser includes a pump, the composition is preferably not pressurized in the reservoir and preferably does not contain a propellant.

[0083] The spray dispenser may be a pre-compressed sprayer comprising a pressurized buffer of the composition and a pressure-operated one-way valve between the buffer and the spray nozzle. Such a pre-compressed sprayer provides a more uniform spray distribution and a more uniform spray droplet size because the composition is sprayed at a more uniform pressure. Examples of such pre-compressed sprayers include the Flairosol® spray dispenser manufactured and sold by Afa Dispensing Group (Netherlands), and the pre-compressed trigger sprayer described in U.S. Patent Application Publications 2013 / 0112766 and 2012 / 0048959.

[0084] How to use: The cleaning products described herein are particularly suitable for a method of cleaning tableware, which optionally includes the steps of pre-wetting the tableware, spraying the cleaning composition onto the tableware, optionally scrubbing the tableware, and rinsing the tableware.

[0085] The cleaning products described herein are particularly effective in lifting dirt, especially greasy dirt. Therefore, scrubbing is optional, especially for light dirt, and is optional if the dishes are left to stand for at least 15 seconds, preferably at least 30 seconds, after the spraying step before the rinsing step is performed.

[0086] The scrubbing and rinsing processes can be performed at least partially simultaneously, for example, by scrubbing the dishes under running water or while the dishes are submerged in water. The scrubbing process may take between 1 and 30 seconds.

[0087] This method makes it possible to wash dishes more quickly and easily when they are lightly soiled. When dishes are heavily soiled with stubborn food stains such as cooking residue, baked-on food, and burnt-on food, the method of the present invention facilitates washing when the soiled dishes are immersed in the product of the present invention, either in its undiluted form or diluted with water, for a time preferably 1 to 30 seconds or longer.

[0088] method A) Viscosity: The rheological profile is measured using a "TA instruments DHR1" rheometer (TA instruments, serial number: SN960912) which employs a cone and plate configuration (flat steel Peltier plate and a 60 mm diameter, 2.026° cone). The viscosity measurement procedure includes a conditioning step and a sweep step at 20°C. The conditioning step consists of 10 seconds at zero shear at 20°C, followed by 10 seconds at 20°C. -1 The process consists of pre-shearing for 10 seconds, followed by equilibration of the sample at 20°C with zero shear for 30 seconds. The sweeping step is performed at 20°C for 0.01 seconds. -1 3,000 seconds -1 The shear rate is increased logarithmically until the maximum acquisition rate is reached, with a sampling time of 15 s and an acquisition rate of 10 points per 10, and a maximum equilibration time of 200 s (determined by rheometer based on a tolerance of 3%). When measuring shear-fluidized product compositions, high shear viscosity is 1,000 s -1It is defined by the shear rate, and low shear viscosity is 0.1 s -1 It is defined by the shear rate. The product composition of Newtonian fluids is 1000 seconds -1 The shear rate is recorded.

[0089] B) Stability: The liquid composition is stored in a 30 mL glass vial at 50°C for 1 day, and then the phase stability of the liquid composition is visually evaluated.

[0090] C) Removal of crystalline lipids: To enable comparative analysis of the crystalline grease removal capabilities of a range of test compositions, the test compositions are sprayed onto a soiled substrate containing crystalline grease, and the removal rate (%) after the cleaning test is evaluated by visual grading as described below.

[0091] The crystalline grease stain used consisted of a mixture of CABF (Consumer Average Beef Fat, L2802405 / 200B3 / E3, supplied by J&R Coordinating Services Inc (Ohio, USA)) and a 0.05% by weight concentration of an oil-soluble dye (Dye EGN Oil Red: CAS: 4477-79-6, Sigma Aldrich Ref. 234117). The crystalline grease stain was prepared by melting the CABF in a 50°C oven until completely liquefied, and then mixing in the dye.

[0092] Molten CABF at 50°C was uniformly deposited over the entire surface of an enamel tile (25cm x 7cm white enamel tile, supplied by Emaillerie Belge (Rue Saint-Denis 122, 1190 Forest, BE)) using a synthetic foam paint roller until 0.65g ± 0.05g of CABF was deposited. Before use in the test, the tile was left to stand for 3 hours at 23°C and 50 RH humidity.

[0093] For each test composition, the test was repeated three times using three different enamel tiles.

[0094] Three tiles were placed horizontally on the surface. Using a Flairosol® sprayer (supplied by AFA), the test solution was sprayed six times for a total of approximately 5 seconds, covering half of the tile surface, and allowed to stand for 4 minutes. The tiles were then rearranged vertically, 20 mL of demineralized water was sprayed onto the tiles twice, and the foam was rinsed off using a 20 mL syringe.

[0095] Photographs of the tiles were taken using a digital camera, and then visually graded on a scale of 0 to 5, with grade 0 representing no change and grade 5 representing complete removal of crystalline lipids. [Examples]

[0096] The crystalline grease removal efficacy of the liquid detergent spray composition according to the present invention and comparative compositions outside the scope of the present invention was evaluated.

[0097] In Table 1, Example 1 of the present invention included a combination of the solvent of formula (I), tripropylene glycol n-butyl ether, and the solvent of formula (II), tripropylene glycol methyl ether, in addition to a surfactant system consisting of a C8-C10 alkyl polyglucoside, a C12-C14 dimethylamine oxide as an auxiliary surfactant, and a C6EO5 nonionic surfactant. The resulting composition was stable and effective in removing crystalline fats with little to no scrubbing. Comparative Example A was the same as Example 1 except that it did not contain the solvent of formula (II). Thus, the composition was effective in removing crystalline fats, but the composition was not stable and underwent phase separation. Comparative Example B was the same as Example 1 except that it contained ethanol instead of the solvent of formula (II). Therefore, the composition was stable, but the solvent of formula (I) was not very effective in removing crystalline fats in the composition.

[0098] Example 2 of the present invention was the same as Example 1, except that it had a pH of 7.0 instead of 11.2. By comparing the results of Example 2 of the present invention with the results of Example 1 of the present invention, it can be seen that when the composition is formulated to have a more neutral pH, the removal of crystalline fat is improved with little to no scrubbing. Comparative Example C was the same as Example 2, except that it did not contain the solvent of formula (II). Thus, the composition was effective in removing crystalline fat, but the composition was not stable and underwent phase separation. Comparative Example D was the same as Example 2, except that it contained ethanol instead of the solvent of formula (II). Therefore, the composition was stable, but the solvent of formula (I) was not very effective in removing crystalline fat in the composition.

[0099] Comparing the results of Comparative Example C with those of Example 2 of the present invention, it is shown that the benefits of the solvent combination of formulas (I) and (II) exist even at lower pH levels where components such as fragrances are more chemically and olfactorily stable.

[0100] [Table 1] * comparison 1 Glucopon® 215, supplied by BASF 2 Lutensol® CS6250, supplied by BASF. 3 The solvent of formula (I), sold under the trade name Dowanol TPNB, is supplied by DOW. 4 The solvent of formula (II), sold under the trade name Dowanol TPM, is supplied by DOW.

[0101] In Table 2, Example 3 of the present invention included a combination of the solvent of formula (I), tripropylene glycol n-butyl ether, and the solvent of formula (II), tripropylene glycol methyl ether, in addition to a surfactant system consisting of a C12-C14 alkyl polyglucoside, a C12-C14 dimethylamine oxide as an auxiliary surfactant, and a C6EO5 nonionic surfactant. The resulting composition was stable and effective in removing crystalline fats with little to no scrubbing. Comparative Example E was the same as Example 3 except that it did not contain the solvent of formula (II). Thus, the composition was effective in removing crystalline fats, but it was not stable and underwent phase separation. Comparative Example F was the same as Example 1 except that it contained ethanol instead of the solvent of formula (II). Thus, the composition was stable, but its effect in removing crystalline fats was low.

[0102] Example 4 of the present invention was the same as Example 3, except that it had a pH of 7.0 instead of 11.2. By comparing the results of Example 4 of the present invention with the results of Example 3 of the present invention, it can be seen that when the composition is formulated to have a more neutral pH, the removal of crystalline fats is improved with little to no scrubbing.

[0103] Comparing the results of Comparative Example G with those of Example 3 of the present invention, it is shown that the benefits of the solvent combination of formulas (I) and (II) exist even at lower pH levels.

[0104] The results of Examples 1-2 and 3-4 of the present invention demonstrate that the solvent combinations of formulas (I) and (II) are beneficial when the surfactant system contains alkyl polyglucosides of different chain lengths, over a wide range of surfactant concentrations.

[0105] [Table 2] 1 Glucopon® 600, supplied by BASF 6Another ether solvent, sold under the trade name Dowanol DPNB, supplied by DOW.

[0106] In Table 3, Comparative Example I and Examples 5-7 of the present invention contained the same surfactant system and the same concentration of glycol ether solvent of formula (I), but the weight ratio of solvent of formula (I) to solvent of formula (II) was reduced. The results show that improved stability is achieved when the weight ratio of solvent of formula (I) to solvent of formula (II) is less than 2.5 or less than 2.0.

[0107] [Table 3]

[0108] In Table 4, the examples contained an anionic surfactant at a concentration exceeding 3.0% by weight of the composition. Therefore, both compositions were comparative examples. Examples J and K demonstrate that compositions containing high concentrations of anionic surfactant already provide good stability, and that there are no problems in stably incorporating the hydrophobic glycol ether solvent of formula (I) in such anionic-rich compositions. However, as noted herein, spray droplets from such compositions tend to cause greater irritation to the nose and eyes.

[0109] [Table 4]

[0110] The data in Table 4 demonstrates that the challenge of stabilizing liquid compositions containing the glycol ether solvent of formula (I) does not exist for compositions containing high concentrations of anionic surfactants.
