Abstract
Description
Technical Field
[0001] The present invention is in the field of cleaning compositions. Background Art
[0002] Removing stubborn food stains in a faster and easier way is an ongoing goal in dishwashing. Historically, pure grease stains have received the most attention. In addition, conventional detergents and cleaning equipment easily meet daily cleaning needs. However, removing heavily encrusted and burned-on stains remains a challenge. Common methods include extended soaking and / or heavy scrubbing. Professional solutions such as pre-treatment products can often be effective, but are extremely abrasive or corrosive (high pH) to hands and surfaces. In addition, they are inconvenient for consumers because multiple products are required to completely clean. An increasingly serious problem comes from the increased use of microwave ovens that provide more intensive cooking. Therefore, it is desirable to have a detergent that is effective in removing stubborn stains. In addition, it is desirable to prepare a translucent cleaning composition incorporating the desired composition. Summary of the invention
[0003] A method for preparing a translucent cleaning composition is disclosed. The method comprises providing a perfume, providing a hydrogen bond accepting compound, providing a hydrogen bond donating compound, mixing the hydrogen bond accepting compound with the hydrogen bond donating compound to produce a eutectic liquid, adding the perfume to the eutectic liquid to produce a scented eutectic liquid, and adjusting the pH of the scented eutectic liquid to above 6.0.
[0004] A method for preparing a translucent cleaning composition is also disclosed. The method includes providing a perfume; providing a hydrogen bond accepting compound; providing a hydrogen bond donating compound; mixing the hydrogen bond accepting compound with the hydrogen bond donating compound to produce a eutectic liquid; adding the perfume to the eutectic liquid to produce a scented eutectic liquid; adjusting the pH of the scented eutectic liquid to above 6.0; and mixing the scented eutectic liquid with a solvent and a surfactant to form a cleaning composition, wherein the cleaning composition exhibits an absorbance greater than 60% at 600 nanometers.

[0011] The following description of the preferred embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.The following description relates to a cleaning composition.
[0012] The composition includes a hydrogen bond acceptor in the form of an amino acid or a quaternary ammonium salt. The amino acid can be selected from l-arginine, l-proline, l-alanine, l-phenylalanine, l-glutamine, l-lysine, beta-alanine, glycine, betaine. The quaternary ammonium salt can be a choline salt to improve the cleaning efficiency of the composition.
[0013] The amount of choline chloride can be at least 7.5 wt%, at least 10 wt%, at least 15 wt%, at least 20 wt%, at least 25 wt%, at least 30 wt%, at least 35 wt%, at least 40 wt%, at least 50 wt%, at least 55 wt%, at least 60 wt%, at least 65 wt%, at least 70 wt%, at least 75 wt%, at least 80 wt%, at least 85 wt%, or at least 90 wt%. In certain embodiments, the amount of choline bicarbonate is at least 1 wt%, 5 wt%, 7.5 wt%, at least 10 wt%, at least 15 wt%, at least 20 wt%, at least 25 wt%, at least 30 wt%, at least 35 wt%, at least 40 wt%, at least 50 wt%, at least 55 wt%, at least 60 wt%, at least 65 wt%, at least 70 wt%, at least 75 wt%, at least 80 wt%, at least 85 wt%, or at least 90 wt%. In certain embodiments, the amount of choline salicylate and / or choline dihydrocholine citrate is at least 0.5 wt%, at least 1 wt%, at least 5 wt%, at least 7.5 wt%, at least 10 wt%, at least 15 wt%, at least 20 wt%, at least 25 wt%, at least 30 wt%, at least 35 wt%, at least 40 wt%, at least 50 wt%, at least 55 wt%, at least 60 wt%, at least 65 wt%, at least 70 wt%, at least 75 wt%, at least 80 wt%, at least 85 wt%, or at least 90 wt%.
[0014] The composition optionally contains a hydrogen bond donor for the choline salt. Examples of hydrogen bond donors include, but are not limited to, urea, aromatic carboxylic acids or salts thereof, salicylic acid, salicylates, benzoic acid, benzoates, dicarboxylic acids or salts thereof, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, tartaric acid, tricarboxylic acids or salts thereof, citric acid or salts thereof.
[0015] The amount of hydrogen bond donor can be at least 1 wt %, at least 5 wt %, at least 10 wt %, at least 15 wt %, at least 20 wt %, at least 25 wt %, at least 30 wt %, at least 35 wt %, at least 40 wt %, at least 50 wt %, at least 55 wt %, at least 60 wt %, at least 65 wt %, at least 70 wt %, or at least 75 wt %.
[0016] The hydrogen bond donor may be present with the choline salt in a weight ratio of 1: 1 to 4: 1. In certain embodiments, the ratio is about 1: 1. In other embodiments, the ratio is about 2: 1 or about 3: 1.
[0017] Choline chloride itself is not a liquid salt, as its melting point is significantly above 100°C. (The upper limit indicated by the definition of a liquid salt). However, the combination of keto and hydroxy acids with simple monocarboxylic acids and dicarboxylic acids in combination with quaternary ammonium salts forms substances known as "deep eutectic solvents", which exhibit liquid salt-like properties in terms of abnormally low melting points. The optimal molar ratio of levulinic acid to choline chloride in terms of minimum melting point reduction is about 5:1 to about 1.5:1, respectively. Surprisingly, it has been found in our studies that such deep eutectic liquids also provide effective solubility and stability of components (e.g., fragrances in solution) to produce clear compositions. In addition, it has been surprisingly found that the disclosed ratios produce solutions that leave high gloss levels on surfaces after cleaning.
[0018] The cleaning composition may include a quaternary ammonium salt compound. The quaternary ammonium salt has the following formula:
[0019]
[0020] Where R 1 is hydrogen or an aliphatic group having 1 to 22 carbon atoms; R 2 is an aliphatic group having 10 to 22 carbon atoms; R 3 and R 4 Each is an alkyl group having 1 to 3 carbon atoms; and X is an anion selected from the group consisting of halogen, acetate, phosphate, nitrate and methylsulfate.
[0021] Representative examples of the quaternary ammonium salt constituting component (i) of the present invention include tallow trimethyl ammonium chloride; ditallow dimethyl ammonium chloride; ditallow dimethyl ammonium methyl sulfate; dihexadecyl dimethyl ammonium chloride; bis(hydrogenated tallow) dimethyl ammonium chloride; dioctadecyl dimethyl ammonium chloride; dieicosyl dimethyl ammonium chloride; dibehenyl dimethyl ammonium chloride; bis(hydrogenated tallow) dimethyl ammonium methyl sulfate; dihexadecyl diethyl ammonium chloride; dihexadecyl dimethyl ammonium acetate; choline chloride; ditallow dipropyl ammonium phosphate; ditallow dimethyl ammonium nitrate; and bis(cocoalkyl) dimethyl ammonium chloride.
[0022] A particularly preferred quaternary ammonium fabric conditioner is ditallow dimethyl ammonium chloride, commercially available from General Mills, Inc. under the trade name ALIQUAT-2HT and from Ashland Oil, Inc. as ADOGEN 448.
[0023] The compositions of the present invention preferably comprise organic hydroxy acids and / or keto acids for providing benefits in regulating skin condition, especially in therapeutically regulating signs of skin aging, more particularly wrinkles, fine lines and pores. Suitable hydroxy acids include C 1 -C 18 Hydroxy acid, preferably C 8 or less. The hydroxy acid may be substituted or unsubstituted, linear, branched or cyclic (preferably linear) and saturated or unsaturated (monounsaturated or polyunsaturated) (preferably saturated). Non-limiting examples of suitable hydroxy acids include glycolic acid, lactic acid, salicylic acid, 5-octanoyl salicylic acid, hydroxyoctanoic acid, hydroxyoctanoic acid and lanolin fatty acid. A non-limiting example of a keto acid is pyruvic acid. The preferred concentration range of the organic hydroxy acid and / or keto acid is from about 0.1% to about 10%, more preferably from about 0.2% to about 5%, and also preferably from about 0.5% to about 2%. Lactic acid, salicylic acid and pyruvic acid are preferred. The organic hydroxy acids enhance the skin appearance benefits of the present invention.
[0024] The compositions described herein may include carboxylic acid monomers. Carboxylic acid monomers useful in forming the copolymers of the present invention are ethylenically unsaturated carboxylic acids containing at least one activated carbon-carbon olefinic double bond and at least one carboxyl group, i.e., acids containing olefinic double bonds that are readily available for polymerization because they are present in the alpha-beta position relative to the carboxyl group in the monomer molecule or as part of a terminal methylene group. Anhydrides, particularly maleic anhydride, may also be used.
[0025] The compositions of the present invention may also contain an organic hydroxy acid. Non-limiting examples of suitable hydroxy acids include salicylic acid, glycolic acid, lactic acid, 5-octanoyl salicylic acid, hydroxyoctanoic acid, hydroxyoctanoic acid and lanolin fatty acid. The preferred acid is levulinic acid.
[0026] The product may use a fragrance delivery system. Certain fragrance delivery systems, methods of making certain fragrance delivery systems, and uses of such fragrance delivery systems are disclosed in USPA 2007 / 0275866 Al.
[0027] Such fragrance delivery systems include:
[0028] Polymer Assisted Delivery (PAD): This fragrance delivery technology uses polymer materials to deliver fragrance materials. Some examples are typical agglomerates, water-soluble or partially water-soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, plastics filled with fragrances, microcapsules, nano- and micro-latexes, polymer film formers and polymer absorbents, polymer adsorbents, etc. PAD includes, but is not limited to: a.) Matrix system: the fragrance is dissolved or dispersed in a polymer matrix or particles. The fragrance can be, for example, 1) dispersed into the polymer before being formulated into the product, or 2) added separately from the polymer during or after the formulation of the product. Although many other triggers that control the release of fragrances are known, the diffusion of fragrances from polymers is a common trigger mechanism, which enables the fragrance to be released at a certain rate from a polymer matrix system deposited or applied to the desired surface (site), or to increase the rate. Absorption and / or adsorption into or onto polymer particles, films, solutions, etc. is an aspect of this technology. Examples are nanoparticles or microparticles composed of organic materials (e.g., latex). Suitable particles include a wide variety of materials including, but not limited to, polyacetals, polyacrylates, polyacrylics, polyacrylonitrile, polyamides, polyaryletherketones, polybutadiene, polybutylene, polybutylene terephthalate, polychloroprene, polyethylene, polyethylene terephthalate, polycyclohexylene dimethylene terephthalate, polycarbonates, polychloroprene, polyhydroxyalkanoates, polyketones, polyesters, polyethylene, polyetherimides, polyethersulfones, chlorinated polyethylene, polyimides, polyisoprene, polylactic acid, polymethylpentene, polyphenylene oxide, polyphenylene sulfide, polyphthalamide, polypropylene, polystyrene, polysulfones, polyvinyl acetate, polyvinyl chloride, and polymers or copolymers based on acrylonitrile-butadiene, cellulose acetate, ethylene-vinyl acetate, ethylene-vinyl alcohol, styrene-butadiene, vinyl acetate-ethylene, and mixtures thereof.
[0029] "Standard" systems refer to "those that are preloaded", which are intended to keep the preloaded fragrance associated with the polymer until one or more times when the fragrance is released. Such polymers can also suppress the pure product odor and provide a strong and / or lasting benefit, depending on the fragrance release rate. A challenge for such systems is to obtain an ideal balance between: 1) stability in the product (keeping the fragrance inside the carrier until you need it) and 2) timely release (during use or from a dry position). It is particularly important to obtain this stability during storage in the product and product aging. This problem is particularly evident for water-based products such as heavy-duty liquid laundry detergents containing surfactants. When formulated into water-based products, many "standard" matrix systems that can be effectively obtained become "balanced" systems. "Balanced" systems or "storage" systems can be selected, which have acceptable diffusion stability in the product and available trigger mechanisms for release (such as friction). "Balanced" systems are those systems in which the fragrance and polymer can be added to the product separately, and the balanced interaction between the fragrance and the polymer leads to beneficial effects on one or more consumer touch points (relative to free fragrance without polymer-assisted delivery technology). The polymer can be preloaded with fragrance; however, some or all of the fragrance may diffuse during storage in the product, reaching a balance, the balance including the desired fragrance raw material (PRM) and the polymer association. The polymer then carries the fragrance to the surface and is usually released via fragrance diffusion. The use of such a balanced system polymer potentially reduces the pure product odor intensity of the pure product (usually more so for a preloaded standard system). The deposition of such a polymer is used to make the release feature "flat" and provide an increased shelf life. As described above, such a shelf life will be achieved by suppressing the initial intensity, and the formulator can use a higher impact or low odor detection threshold (ODT) or low Kovalz index (KI) PRM to obtain FMOT benefits without too strong or distorted initial intensity. Importantly, the fragrance release occurs within the application time period to affect the desired one or more consumer contact points. Suitable microparticles and microlatex and their methods of manufacture can be found in USPA 2005 / 0003980A1. The matrix system also includes hot melt adhesives and fragrance plastics. In addition, hydrophobically modified polysaccharides can be formulated into fragrance products to enhance fragrance deposition and / or modulate fragrance release. All such matrix systems including, for example, polysaccharides and nanolatex can be combined with other PDTs, including other PAD systems such as PAD reservoir systems in the form of perfume microcapsules (PMCs).Polymer-assisted delivery (PAD) matrix systems may include those described in the following references: U.S. Patent Applications 2004 / 0110648A1; 2004 / 0092414A1; 2004 / 0091445A1 and 2004 / 0087476A1; and U.S. Patents 6,531,444; 6,024,943; 6,042,792; 6,051,540; 4,540,721 and 4,973,422.
[0030] Silicones are also examples of polymers that can be used as PDTs, and can provide fragrance benefits in a manner similar to polymer-assisted delivery "matrix systems". Such PDT is referred to as silicone-assisted delivery (SAD). Silicones can be preloaded with fragrances, or used as a balanced system, as described in PAD. Suitable silicones and methods for preparing them can be found in WO2005 / 102261; USPA 20050124530A1, USPA 20050143282A1, and WO 2003 / 015736. Functionalized silicones as described in USPA 2006 / 003913 A1 can also be used. Examples of silicones include polydimethylsiloxanes and polyalkyldimethylsiloxanes. Other examples include those with amine functional groups, which can be used to provide benefits associated with amine-assisted delivery (AAD) and / or polymer-assisted delivery (PAD) and / or amine reaction products (ARP). Other such examples may be found in USP 4,911,852; USPA 2004 / 0058845 A1; USPA 2004 / 0092425 A1 and USPA 2005 / 0003980 A1.
[0031] b.) Storage system: Storage system is also known as core-shell technology, or technology in which the fragrance is wrapped by a fragrance release control membrane that can be used as a protective shell. The material inside the microcapsule is called the core, internal phase or filler, while the wall is sometimes called the shell, coating or membrane. Microparticles or pressure-sensitive capsules or microcapsules are examples of this technology. The microcapsules of the present invention are formed by a variety of processes, including but not limited to coating, extrusion, spray drying, interfacial polymerization, in-situ polymerization and matrix polymerization. Possible shell materials vary greatly in their stability to water. Among the most stable are materials based on polyoxymethylene urea (PMU), which can keep certain PRMs in aqueous solutions (or products) for even longer periods of time. Such systems include but are not limited to urea-formaldehyde and / or melamine-formaldehyde. Stable shell materials include materials based on polyacrylates, which are obtained in the form of reaction products of oil-soluble or dispersible amines with multifunctional acrylate or methacrylate monomers or oligomers, oil-soluble acids and initiators in the presence of an anionic emulsifier containing a water-soluble or water-dispersible acrylic acid alkyl acid copolymer, a base or a base salt. Microcapsules based on gelatin can be prepared so that they dissolve in water quickly or slowly, depending on, for example, the degree of crosslinking. Many other capsule wall materials are available, and the observed fragrance diffusion stability is different. Without being bound by theory, after, for example, being deposited on the surface, the release rate of fragrance from the capsule is generally the reverse order of the fragrance diffusion stability in the product. Therefore, for example, urea-formaldehyde and melamine-formaldehyde microcapsules generally require a release mechanism other than diffusion release or release in addition to diffusion release, such as mechanical forces (such as friction, pressure, shear stress) for breaking the capsule and improving the fragrance (fragrant) release rate. Other triggering mechanisms include melting, dissolving, hydrolysis or other chemical reactions, electromagnetic radiation, etc. The use of preloaded microcapsules requires stability in the product to be released into an appropriate ratio when used and / or on the surface (on the site), and PRM is appropriately selected. Microcapsules based on urea-formaldehyde and / or melamine-formaldehyde are relatively stable, especially in near-neutral water-based solutions. These materials may require a friction triggering mechanism, which may not be suitable for all product applications. Other microencapsulated materials (eg, gelatin) may not be stable in water-based products and may even provide diminished benefits (relative to free fragrance control) when aged within the product. Scratch fragrance technology is another example of a PAD.Perfume microcapsules (PMCs) may include those described in the following references: U.S. Patent Applications: 2003 / 0125222 A1; 2003 / 215417 A1; 2003 / 216488 A1; 2003 / 158344 A1; 2003 / 165692 A1; 2004 / 071742 A1; 2004 / 071746 A1; 2004 / 072719 A1; 2004 / 072720 A1; 2006 / 0039934 A1; 2003 / 203829 A1; 2003 / 195133 A1; 2004 / 087477 A1; 2004 / 0106536 A1; and U.S. Patents 6,645,479B1; 6,200,949B1; 4,882,220; 4,917,920; 4,514,461; 6,106,875 and 4,234,627, 3,594,328 and US RE 32713; PCT patent applications: WO 2009 / 134234 A1, WO 2006 / 127454 A2, WO 2010 / 079466 A2, WO 2010 / 079467A2, WO 2010 / 079468 A2, WO 2010 / 084480 A2.
[0032] Molecular Assisted Delivery (MAD): Non-polymeric materials or molecules can also be used to improve the delivery of fragrances. Without being bound by theory, fragrances can interact non-covalently with organic materials, resulting in changes in deposition and / or release. Non-limiting examples of such organic materials include, but are not limited to, hydrophobic materials such as organic oils, waxes, mineral oils, petrolatum, fatty acids or esters, sugars, surfactants, liposomes, and even other fragrance raw materials (fragrance oils) and natural oils (including body dirt and / or other dirt). Fragrance fixatives are another example. In one aspect, non-polymeric materials or molecules have a CLogP greater than about 2. Molecular Assisted Delivery (MAD) can also include those described in USP 7,119,060 and USP 5,506,201.
[0033] III. Fiber Assisted Delivery (FAD): The selection or use of the site itself can be used to improve the delivery of the fragrance. In fact, the site itself can be a fragrance delivery technology. For example, different fabric types such as cotton or polyester will have different properties in terms of the ability to attract and / or retain and / or release fragrances. The amount of fragrance deposited on or in the fiber can be changed according to the selection of the fiber, and also according to the origin or treatment of the fiber, and according to any fiber coating or treatment. The fiber can be woven and non-woven, and can be natural or synthetic. Natural fibers include those prepared by plants, animals and geological effects, and include but are not limited to cellulosic materials such as cotton, linen, hemp, jute, flax, ramie and sisal, as well as fibers used to make paper and cloth. Fiber Assisted Delivery can include the use of wood fibers, such as thermodynamic wood pulp and bleached or unbleached kraft pulp or sulfite pulp. Animal fibers are mainly composed of specific proteins, such as silk, tendons, gut and hair (including wool). Polymer fibers based on synthetic chemistry include, but are not limited to, polyamide nylon, PET or PBT polyester, phenol formaldehyde (PF), polyvinyl alcohol fiber (PVOH), polyvinyl chloride fiber (PVC), polyolefins (PP and PE), and acrylic polymers. All such fibers can be preloaded with fragrances and then added to products that may or may not contain free fragrances and / or one or more fragrance delivery technologies. In one aspect, the fiber can be added to the product before being loaded with fragrances, and then loaded with fragrances by adding fragrances, which can diffuse into the fiber, into the product. Without being bound by theory, the fragrance can be adsorbed onto the fiber or absorbed into the fiber during, for example, storage of the product, and then released at one or more key moments or consumer contact points.
[0034] IV. Amine Assisted Delivery (AAD): The amine assisted delivery technology method utilizes materials containing amine groups to increase fragrance deposition or adjust fragrance release during product use. In this method, there is no need to pre-compound or pre-react one or more fragrance raw materials and amines before adding to the product. In one aspect, the amine-containing AAD materials suitable for use herein can be non-aromatic; for example, polyalkylimines such as polyethyleneimine (PEI) or polyethyleneamine (PVAm), or aromatic such as anthranilate. Such materials can also be polymeric or non-polymeric. In one aspect, such materials contain at least one primary amine. This technology will allow for increased persistence and controlled release of low ODT notes (e.g., aldehydes, ketones, enones) via amine functional groups, and, without being bound by theory, increased delivery of other PRMs via polymer-assisted delivery of polymerized amines. Without this technology, volatile top notes would be lost too quickly, leaving a higher ratio of middle and base notes to top notes. The use of polymeric amines allows higher levels of top notes and other PRMs to be used to obtain a more recent shelf life without causing the pure product to have a stronger smell than desired, or allows top notes and other PRMs to be used more effectively. In one aspect, the AAD system effectively delivers PRMs at a pH greater than neutral. Without being bound by theory, conditions in which a majority of the amines in the AAD system are deprotonated can result in an increased affinity of the deprotonated amines for PRMs such as aldehydes and ketones, including unsaturated ketones and enones such as damascone. In another aspect, polyamines effectively deliver PRMs at a pH below about neutral. Without being bound by theory, conditions in which a majority of the amines in the AAD system are protonated can result in a reduced affinity of the protonated amines for PRMs such as aldehydes and ketones, and a polymer backbone with a strong affinity for a variety of PRMs is obtained. In this aspect, polymer-assisted delivery can deliver a variety of fragrance benefits; such systems are a subclass of AAD and can be referred to as amine-polymer-assisted delivery or APAD. In some cases, when the APAD is used in a composition having a pH less than 7, such APAD systems may also be considered polymer-assisted delivery (PAD). On the other hand, AAD and PAD systems may interact with other materials, such as anionic surfactants or polymers to form coacervates and / or coacervate-like systems. On the other hand, materials containing heteroatoms such as sulfur, phosphorus or selenium that are not nitrogen may be used as substitutes for amine compounds. On the other hand, the aforementioned alternative compounds may be used in combination with amine compounds. On the other hand, a single molecule may contain an amine moiety and one or more alternative heteroatom moieties, such as thiols, phosphines and selenols. Suitable AAD systems and methods of making them are found in U.S. Patent Applications 2005 / 0003980 A1; 2003 / 0199422 A1; 2003 / 0036489 A1; 2004 / 0220074 A1 and USP 6,103,678.
[0035] V. Cyclodextrin Delivery System (CD): This technology method uses cyclic oligosaccharides or cyclodextrins to improve the delivery of fragrances. Generally, a complex of fragrance and cyclodextrin (CD) is formed. Such complexes can be pre-formed, formed in situ, or formed on or in the site. Without being bound by theory, water loss can be used to shift the equilibrium toward the CD-fragrance complex, especially when other auxiliary ingredients (such as surfactants) are not present in high concentrations and do not compete with the fragrance for the cyclodextrin pore cavity. If contact with water or increased water content occurs at a later point in time, a rich benefit may be obtained. In addition, cyclodextrins can increase the flexibility of fragrance formulators in selecting PRMs. Cyclodextrins can be pre-loaded with fragrances, or added separately from fragrances to obtain the desired fragrance stability, deposition or release benefits. Suitable CDs and methods for their preparation can be found in USPA 2005 / 0003980 Al and 2006 / 0263313 Al and in US Pat. Nos. 5,552,378; 3,812,011; 4,317,881; 4,418,144 and 4,378,923.
[0036] VI. Starch Encapsulated Admixtures (SEAs): The use of starch encapsulated admixtures (SEAs) technology can allow, for example, the conversion of liquid flavors into solids by adding ingredients such as starches to adjust the properties of the flavors. The benefits include improved retention of flavors during product storage, especially under non-aqueous conditions. Upon contact with water, flavor intensity can be triggered. Benefits at precise other times can also be obtained because the starch allows the product formulator to select PRMs or PRM concentrations that would not normally be used without the presence of SEAs. Another technical example includes the use of other organic and inorganic materials such as silica to convert flavors from liquids into solids. Suitable SEAs and methods of making them can be found in USPA 2005 / 0003980 A1 and USP 6,458,754 B1.
[0037] VII. Inorganic Carrier Delivery System (ZIC): This technology involves the use of porous zeolites or other inorganic materials to deliver fragrances. The fragrance-loaded zeolites can be used with or without auxiliary ingredients, such as coating the fragrance-loaded zeolites (PLZ) to change the fragrance release characteristics of the product during storage or during use, or to change the characteristics of the fragrance release from dry parts. Suitable zeolites and inorganic carriers and methods for their preparation can be found in USPA 2005 / 0003980 A1 and U.S. Patents 5,858,959; 6,245,732 B1; 6,048,830 and 4,539,135. Silica is another form of ZIC. Another example of a suitable inorganic carrier includes inorganic tubules, wherein the fragrance or other active substance is contained in the lumen of the nano- or micro-tubules. In one aspect, the inorganic tubules loaded with fragrances (or Tubules or PLTs loaded with fragrances) are mineral nano- or micro-tubules, such as halloysite or a mixture of halloysite and other inorganic materials including other clays. The PLT technology may also include additional ingredients on the inside and / or outside of the tubules for improving diffusion stability in the product, for the purpose of deposition at a desired location, or for controlling the release rate of the loaded fragrances. Monomeric materials and / or polymeric materials, including starch encapsulates, may be used to coat, fill, cap or otherwise encapsulate the PLT. Suitable PLT systems and methods for their preparation may be found in USP 5,651,976.
[0038] VIII. Pro-perfume (PP): This technology refers to perfume technology, which results from the reaction of perfume materials with other matrices or chemicals to form materials with covalent bonds between one or more PRMs and one or more carriers. PRMs are converted into new materials called pro-PRMs (i.e., pro-perfumes), which can then release the initial PRMs when exposed to a trigger, such as water or light. Pro-perfumes can provide enhanced perfume delivery properties, such as increased perfume deposition, persistence, stability, retention, etc. Pro-perfumes include those that are monomers (non-polymers) or polymers, and can be preformed or can be formed in situ under equilibrium conditions, such as those present during storage in the product or on wet or dry positions.

Such light-triggered pro-flavors (PPP) include but are not limited to those that release coumarin derivatives and spices and / or pro-flavors when triggered. The released pro-flavors can release one or more PRMs via any of the above-mentioned triggering mechanisms. In one aspect, the light-triggered pro-flavor releases nitrogen-based pro-flavors when exposed to light and / or moisture triggering mechanisms. On the other hand, the nitrogen-based pro-flavors released by the light-pro-flavor release one or more PRMs, which are selected from, for example, aldehydes, ketones (including enones) and alcohols. In another aspect, PPP releases dihydroxycoumarin derivatives. The light-triggered pro-flavor can also be an ester, which releases coumarin derivatives and perfume alcohols. In one aspect, the pro-flavor is a benzoin dimethyl ether derivative, as described in USPA 2006 / 0020459 A1. In another aspect, the pro-fragrance is a 3',5'-dimethylbenzoin (DMB) derivative that releases an alcohol upon exposure to electromagnetic radiation.

[0105] The invention is further described by the following examples. The examples are merely illustrative and do not in any way limit the scope of the invention as described and claimed.

[0110] like Figure 1 As shown, it was surprisingly found that by using a specific molar ratio of acid to choline chloride, a translucent solution can be produced. Figure 1 As shown, at a ratio of 5:1 to 1.5:1 (sample 100, sample 102, sample 104, sample 106, and sample 108), a translucent formulation can be obtained. However, at a ratio of 1:1 or lower, the formulation becomes turbid and / or is no longer translucent (sample 110 and sample 112).
[0111] Similarly, if Figure 2 As shown, the molar ratio can be changed depending on the acid source. For example, when urea is used, the ratio that produces a translucent formulation is between 3:1 (sample 118) and 1.5:1 (sample 122) or about 2:1 (sample 120). Exceeding this range in either direction produces a turbid formulation (samples 114, 116, 124, and 126).
[0112] like Figure 3 As shown, it has been further found that Figure 1 to Figure 2 The use of the molar ratios described in can be used to increase the amount of essential oil that can be dissolved in a formulation while still producing a clear or translucent formulation. Specifically, Figure 3As shown, when dissolving essential oils, if only levulinic acid (sample 130), only choline chloride (sample 132), or levulinic acid and choline chloride are mixed with the essential oils before mixing them (sample 134), a less clear or translucent formulation can be obtained than when levulinic acid and choline chloride are mixed together before adding the essential oils.
[0113] It has further been surprisingly discovered that by manipulating the order of addition of materials in the formulation, significantly different results can be obtained. Specifically, it has been discovered that by adding the fragrance to the formulation after the choline chloride / acid blend is created and before the pH is adjusted, a translucent formulation with a higher fragrance content can be produced. Figure 4 As shown, this manufacturing sequence produces translucent to clear formulations (Sample 136, Sample 138, and Sample 140). Figure 4 As shown, by adding the fragrance after the pH adjustment of the formulation, the resulting formulation becomes turbid and neither translucent nor transparent (Sample 142, Sample 144, and Sample 146). Without being bound by theory, it is believed that by adding the fragrance before the pH adjustment, the fragrance is allowed to be dissolved by the choline chloride / acid mixture. Once the pH is adjusted, the fragrance may no longer dissolve due to the alkaline nature of the formulation.
[0114] This is Figure 5 Further exemplified in, wherein the pH adjusted formulations produced transparent or clear formulations at a 2:1 molar ratio of levulinic acid:choline chloride (sample 154), a 3:1:5 weight ratio of succinic acid:adipic acid:glutaric acid (sample 152), a 1:8:1 weight ratio of succinic acid:adipic acid:glutaric acid (sample 150), and a 1:1:5 weight ratio of succinic acid:adipic acid:glutaric acid (sample 148). In contrast, for the same formulations, if the flavor is added after pH adjustment, there are no other changes to the composition or manufacturing process, but with the exception of the levulinic acid:choline chloride formulation (sample 162), cloudy and / or non-clear formulations (samples 156, 158, and 160) are the result.
[0115] Figure 4 and Figure 5 The example is further illustrated by the data in Table 3 below: Absorbance data of fresh solution and aged solution at 600 nm
[0116]
[0117] As shown in Table 3, clear solutions were produced for the 1% and 2% choline chloride formulations containing 5% of the acid blend, respectively, after pH adjustment and before flavor addition. Addition of natural flavor to the 1% and 2% choline chloride solutions containing 5% of the acid blend, respectively, produced cloudy, unstable solutions. Specifically, as shown in the table, by adding flavor to the formulation after the choline chloride / acid blend is produced and before pH adjustment, compositions can be produced that exhibit an absorbance at 600 nanometers greater than 60% or between 60% and 90% for both fresh and aged compositions, e.g., greater than 70%, greater than 80%, greater than 85% for both fresh and aged compositions.
[0118] Turbidity measurements of the solution measured initially and after 3 weeks of stabilization at 25°C showed absorbances below 55%, consistent with aging. Turbidity measurements of the 1:2 levulinic acid:choline chloride solution measured initially and after 3 weeks of stabilization at 25°C showed absorbances above 85%, consistent with aging.
[0119] Additionally, without being bound by theory, it is believed that the increased solubility of the fragrance allows the fragrance to be better retained within the composition. Specifically, it is believed that by dissolving the fragrance with the eutectic liquid, the top and middle odors can be retained, allowing them to disperse and deliver the target aroma when used. This is in contrast to formulations that do not retain the fragrance within the eutectic liquid, which allow the fragrance and the top and middle odors within the fragrance to diffuse into the atmosphere over time, thereby delivering a fragrance that is not equivalent to the original fragrance added to the composition.
[0120] This can be demonstrated using a diffusion test, where the formulation weight is measured at an initial time point and then after being held at a fixed temperature for a fixed amount of time. By comparing the two weights, the amount of fragrance that has diffused from the product can be determined. Without being bound by theory, and recognizing that increased temperature will result in higher diffusion, it is believed that at temperatures between 25C and 40C, 1% to 50% of the fragrance may diffuse within a month.
[0121] The above-mentioned formulation can be applied as a low viscosity aerosol spray or pump spray product. Alternatively, they can be modified as required with salt, surfactant, polymer or other thickeners to produce a medium to high viscosity liquid, flushing gel or gelled liquid that can be poured or wiped onto the surface with dirt. The treatment can be used for baking trays, conventional or microwave surfaces, cooking surfaces or other cooking devices that have been stained with food residues. They are very suitable for removing stains from protein, carbohydrate and grease sources such as kitchen floors, bathroom tubs / showers, sinks and toilets from other hard surfaces. Consumers expect low foaming products, which require minimal flushing for these tasks. These formulas contain choline chloride and contain a mixture of one or more cosolvents in addition to enhance performance.
[0122] Test Method :
[0123] Turbidimetric analysis of essential oil dissolution :
[0124] Turbidimetric Analysis The essential oil solubility test is a spectral-based analysis. Data can be collected for fresh products as well as products aged for 3 weeks at 25°C. Turbidity measurements can be performed in a 1.0 cm pathlength sample cell on a scanning dual-beam spectrometer with both deuterium and halogen lamps, such as a Perkin Elmer Lambda 35 UV / Vis spectrometer, or equivalent equipment. Spectral measurements should be obtained via a 400-700 nm absorbance scan versus an air blank. Gently pour the sample into the sample cell to minimize mixing. Record the maximum absorbance at 600 nm for all samples. Samples with an absorbance of ≥85% at 600 nm indicate a stable microemulsion of natural flavors. Samples with an absorbance of ≤85% indicate an unstable microemulsion of natural flavors.
